Abstract:

Deux installations pilote destinées au traitement d'effluents secondaires par culture de micro-algues (Scenedesmus sp.) ont été opérées à Valcartier (effluents domestiques) et Vaudreuil (effluents semi-industriels). Des bassins de 15 000 L ont servi aux cultures en vrac sous conditions naturelles, avec apport de CO2 atmosphérique par huilage. Les paramètres physiques, chimiques et biologiques ont été mesurés. Les résultats montrent que, malgré les limitations en CO2 et en azote, un enlèvement moyen d'environ 95 % pour l'azote (N-NH4+, N-NO2-, N-NO3-) et de 60 % pour le phosphore (P-PO4-3) a été possible à Valcartier durant l'été; les données correspondantes sont de 92 % et de 98 % à Vaudreuil où la production de biomasse (1,02 mg/L-h) a été plus forte qu'à Valcartier (0,39 mg/L-h). Les facteurs pouvant expliquer les différences observées aux deux sites sont présentées. Les résultats montrent la faisabilité technique, durant l'été, de ce type de traitement tertiaire.

Abstract:

L’objectif de ce travail était d’étudier les liens entre les propriétés morphologiques des flocs biologiques et les performances d’un procédé à boues activées en fonction de l’âge de boue. Un protocole d’analyse d’images a tout d’abord été développé afin de mesurer de façon répétable les propriétés morphologiques de flocs biologiques. Une installation pilote d’un procédé à boues activées a ensuite été mise en oeuvre dans des conditions d’alimentation contrôlées pour trois valeurs différentes de l’âge de boue. Un suivi des caractéristiques du pilote a été effectué en termes de propriétés physicochimiques (la demande chimique en oxygène [DCO] en sortie, matières en suspension, indice de boue, taux d’épuration) et de propriétés morphologiques des flocs biologiques (distributions en taille et circularité). Si l’augmentation de l’âge de boue ne semble pas avoir un impact sur la concentration en matières en suspension et le taux d’épuration, l’indice de boue en revanche augmente, induisant ainsi une diminution de la décantabilité de la boue. Concernant les paramètres morphologiques, lors d’un changement d’âge de boue, la taille et la circularité des flocs biologiques augmentent temporairement avant de se restabiliser à leurs valeurs initiales. En régime permanent, les distributions en taille et en circularité semblent indépendantes de l’âge de boue.

Abstract:

Abstract This paper describes the development of a wind turbulence criterion for the safe operation of helicopters to offshore installations. The development of the criterion was recommended following a review of the environmental effects around offshore platform helidecks. Currently, criteria exist for ambient temperature and for vertical wind component in the vicinity of helidecks, but a questionnaire-based survey of helicopter pilots revealed that the principal safety hazard and source of highest workload is turbulence around offshore installations. The new turbulence criterion will plug a long-standing gap in the guidance on offshore helideck design. The paper describes how the criterion has been developed using piloted flight simulation in a research flight simulator together with data from wind tunnel tests on offshore platforms. Initial validation has been successfully performed, and extended to include correlation with the large database of helicopter operational flight data records being collected through the UK North Sea Helicopter Operations Monitoring Programme (HOMP). The turbulence criterion will be used, together with existing criteria on vertical wind component and temperature, in the assessment of new offshore installation designs, or proposed modifications to existing designs, to determine wind conditions where turbulence is likely to be excessive for safe helicopter operations. These will be used to estimate helideck operability and thereby inform the installation topsides design process, and will provide input to the setting and maintenance of helicopter operational limitations for individual installations. The work will lead to improved safety through better prediction of safe operating envelopes and helideck operability at the design stage. In addition, development of the work is expected to enable the wind environment around offshore installations to be mapped and monitored in-service using helicopter flight data records. The new turbulence criterion has been included in updated guidance on helideck design, and offshore installation designers are now required to inform helicopter operators about wind conditions which result in violations of the turbulence criterion on their offshore installations (as is currently the case for the temperature and vertical wind component criteria).

Abstract:

L'utilisation de l'ozone, aujourd'hui très répandue dans les filières de potabilisation, n'est pas sans effet secondaire. De nombreux sous-produits peuvent se former comme notamment les ions bromates, sous produits finaux d'oxydation des bromures contenus dans les eaux. Malheureusement, le mécanisme de production de cette espèce est complexe et dépend de nombreux paramètres difficiles à appréhender. Sur une installation pilote de type colonne à bulles fonctionnant à contre-courant, nous avons étudié l'influence de différents paramètres, comme le pH, le temps de contact, la dose d'ozone et la dose de peroxyde d'hydrogène, sur la formation des bromates et la dégradation des pesticides, représentée par l'atrazine. Les résultats de la littérature ont été confirmés lors de l'emploi unique de l'ozone. La formation des ions bromate est influencée par la présence du peroxyde d'hydrogène. Cet oxydant intervient de manière non négligeable sur la consommation des entités intermédiaires. Le couple HOBr/OBr- peut être oxydé par l'ozone moléculaire et le radical OH° mais peut également être réduit par l'ozone et par le peroxyde sous sa forme acide ou sa base conjuguée. En ce qui concerne la dégradation des pesticides, l'utilisation de peroxyde d'hydrogène couplé à l'ozone favorise l'oxydation de la molécule d'atrazine grâce à la présence plus importante de radicaux hydroxyles. Une pollution accidentelle en pesticides pourra être traitée par l'ajout ponctuel de peroxyde d'hydrogène avec une augmentation de pH, la formation des bromates sera, dans ce cas, faible. La désinfection sera alors assurée par l'étape de chloration.

The article describes the results of studies on a pilot pyrolysis installation with respect to maintenance parameters during pyrolysis of biomass in a form of pellets. Efficiency of raw fuel (pellets made from wood) conversion to processed fuels: coke, oil and post-pyrolytic gas. The described installation is atypical in terms of construction design that is based on the heat conduction mechanism (in most installations, convection in an atmosphere of inert gases or in vacuum is the dominating mechanism). Also, energy balances for biomass pyrolysis are presented.

Abstract:

Research was carried out at the experimental installation defined by the 2 MW furnace pilot from the Politehnica University of Bucharest and ICEMENRG institute who was involved for measurements. The purpose of the experimental study is to confirm that the use of a coal with low sulphur content S<0.08% is possible without the use of sulphurpurification installations for industrial purposes. But, the high moisture content of the coal has imposed the problem of its compatibility with a certain milling technology. The pilot plant is equipped with fan mill and pre-drying tower. Under these conditions, this installation allows the grinding of fuels with high moisture content. The experiments focused on the process of ignition, combustion and pollutant emissions, with the exemplification, in particular, of the emission of sulfur dioxide. Also, the outbreak temperatures and the slugging temperature were monitored. For this purpose, the outbreak of the pilot boiler was equipped with all the equipment necessary to follow these parameters. The experiments have shown positive aspects to the burning of this fuel, thus laying the foundations of future tests at industrial installations (first of all, the power plant from Deva is considered).

Abstract:

The subjective impressions of pedestrians are necessary in order to decide on the appropriate colour of light to be used for street lighting. Therefore, a pilot project aimed to compare subjective evaluations of the sidewalk illumination under two street lighting installations, realised by LEDs of 3000 K (warm white) and 4000 K (neutral white), was recently conducted in Belgrade. Both installations had comparable sidewalk illuminances as well as other relevant photometric parameters. The evaluation was done through a questionnaire. A group of 139 (61 male and 78 female) respondents, all of them university students, was asked to grade both lighting installations for the sidewalk light intensity, the appearance of human faces, the colour of light and the colour rendering as well as the overall impression. According to the median values, the 3000 K LED installation was considered better than the 4000 K installation for all aspects assessed as well as the overall impression. Although the survey results convincingly showed a preference for 3000 K LEDs for this comparison, additional research is needed using a more representative sample of people and a wider range of locations before a definite conclusion can be reached.

Abstract:

Relatively little is known about the distribution and diversity of marine mammals around offshore anthropogenic structures. We present results obtained from incidental sightings of marine mammals around oil and gas installations located 200 km off the Danish coast. A total of 131 sightings corresponding to about 288 animals were reported between May 2013 and May 2016. A total of seven marine mammal species were identified, five cetaceans: harbour porpoise (Phocoena phocoena), minke whale (Balaenoptera acutorostrata), white-beaked dolphin (Lagenorhynchus albirostris), killer whale (Orcinus orca), pilot whales (Globicephala spp.) and two species of pinnipeds: harbour (Phoca vitulina) and grey seals (Halichoerus grypus). The most sighted species were harbour porpoise (41%) and minke whale (31%). Relative counts and biodiversity of marine mammals observed around installations corresponded well with the expected distribution in the central North Sea. Several taxon-specific correlations were identified between number of sightings and environmental parameters (depth and latitude) or installation characteristics (installation aerial footprint). Furthermore, 85% of sightings were made during spring and summer and it is unclear whether the pattern observed reflected a natural seasonal occurrence of marine mammals in the area or an effect of reduced effort during autumn and winter. Despite the potential caveats, results obtained during this programme provide an insight into the relationship between marine mammals and oil and gas offshore installations in the North Sea.

Abstract:

A cleaning site for road and rail car tankers emits a waste water stream of 200-250 m3/d. The waste water was originally treated in a physico-chemical waste water treatment plant. It was required to improve the effluent quality in order to meet the future discharge limits. As a possible treatment technique the sequencing batch reactor (SBR) technology, with an option for powdered activated carbon (PAC) dosing, was selected. Waste water originating from road and rail car cleaning installations is known to be potentially toxic/inhibitory. As a first step in the design procedure a pilot test was run for a period of 8 months. This pilot showed the SBR to be an appropriate technology for the treatment of the waste water. The PAC option was not feasible. Based on the pilot results a full scale installation, comprising a batch reactor with a diameter of 10.4 m and a maximum water depth of 17.3 m, was designed and successfully started up. This paper presents the highlights of the total project.

Abstract:

The article is dedicated to a design of a pilot model of a 60 MW installation, operating according to a new promising compressorless combined cycle. In the course of the study, the weight-size parameters and functional indicators of the main parts of the energy complex were preliminarily determined. The auxiliary components of a compressorless combined cycle unit were selected, such as pumps, heat exchangers, compressors, pipelines and etc. Within a draft elaboration, preliminary weight, size and functional parameters of a turbine unit were defined, solutions were found for two groups of pumping equipment, and a plant prototype was designed. Additionally, the weight and size parameters of the plate heat exchangers were determined and a special design of shell-and-tube heat exchangers was designed to return the heat of combustion products. The results, obtained during the study, make it possible to simulate the behavior (develop dynamic models) of a compressorless combined cycle unit in all operating modes (from start-up to shutdown) under various conditions, as well as to carry out a feasibility study for the creation of such installations.

Abstract:

The data published by the European Container Glass Federation shows that the EU28 average collection rate for recycling of glass containers has grown to a rate of 76%. However the stabilizer produced at mechanical-biological treatment (MBT) installations at landfills still contains large amounts of recyclable glass. An industrial-scale study has been undertaken in order to assess the possibility of recovering this glass from the stabilizer. A new pilot installation was built at the MBT plant in Marszów, Poland. Tests were conducted on stabilizer samples produced at the plant (13 samples) and others collected from several MBT plants based in Poland (six samples). Processing the stabilizer on the designed line made it possible to recover on average 68.4 ± 7.0% of the glass contained in it from Marszów samples and 58.4 ± 14.2% in the case of samples acquired from other MBT installations. It is demonstrated that the concentrate quality largely depends on the stabilizer’s moisture content. A concentrate with glass content from 98.0% to 99.5% was obtained for samples of low-moisture stabilizers (for 14 out of 19 samples). The product was accepted by glass recycling plants due to its low level of contamination with other materials and its appropriate particle size.

Abstract:

The development of organic rice has been implemented in recent years in Pasawahan District, Purwakarta Regency. Philosophically, organic agriculture breaks away from its dependence on external inputs such as the LEISA (Low External Input Sustainable Agriculture) concept, therefore the availability of materials (such as organic fertilizers) provided at the local level is imperative. Consider the potential of livestock in KecamatanPasawahan, so far the utilization of animal waste to become inputs of organic farming production and other uses, such as as an energy source, is still not optimal. This community service activity aims to re-introduce the knowledge of organic fertilizer and introduce biogas/biodigester technology. In particular, this program seeks to apply that knowledge in the form of piloting the manufacture of organic fertilizers and installation of portable biogas installations at the site of community work activities. To achieve this, this program applied participatory approaches to the entire empowerment process, including workshop activities, training, monitoring and evaluation, and mentoring and consultancy, all of which are conducted in a participatory way. Related to the limited facilities and budgeting, for biodigester installations was conducted at one farmer's stall location, which is expected to become a model, while for the pilot of organic fertilizer making is done at several locations of farmer's land.

Abstract:

The technology of thermal utilization of meat-and-bone meal (MBM) is still at the research state. However, there are already a number of existing pilot-scale installations that provide the complete, effective and environmentally safe process conducting. The universal technology was developed that allows to combust various types of waste, including animal waste, municipal waste and sludge, mixed at any ratio with different types of biomass. It provides the possibility to utilize the waste-and-biomass fuel mixtures of up to 90%wt of moisture content, whilemaintaining the allowable pollutant emission to the atmosphere and soil. This regards mainly NOx, SO2, HCl and VOC. Contrary to the typical large scale grate boilers used for waste incineration, the developed operating pilot-scale plant with a capacity of 12MW offers the complete combustion of animal meal, resulting in a flue gas which is proved to be free of flammable gaseous components and sooty particles in slag and fly ash. The thermal decomposition and combustion of waste using this technology ensuresthermal conversion of chemical energy contained in waste and biomass intothe heat and electricity, while preserving the optimum thermodynamic efficiency of technological system. The efficiency of the prototype installation varied between 88.36 and 84.84% depending on the load.

Abstract:

The study specifies the value of the dust resistance coefficient in the process of wood dust filtration in a pilot-scale test stand. The experiments were carried out for one type of filter material—polyester with a PP film previously used in different production lines. Filter bags from the filtering installation of the processing line for narrow surfaces of furniture panels of the honeycomb structure with a chipboard frame, HDF, natural veneer cladding, and a line of CNC drilling machines, were taken into account. Before the pilot-scale tests, the bags had been in use in industrial installations from zero to nine months. All tests were performed under identical filtration conditions. The values of the dust resistance coefficient depend on the operating time and the conditions in which filtration is carried out in an industrial plant, and increased from 6507 s−1 to 10,208 s−1 for the bags from the filter of the narrow surfaces processing line and to 29,729 s−1 for the bags from the filter of the drilling line. The most important factor influencing the properties of the filter bag in the process of wood dust filtration in an industrial filter is the cleaning pulses frequency.

Abstract:

This publication presents research work which contains the optimum parameters of the agri-biomass: maize and oat straws torrefaction process. Parameters which are the most important for the torrefaction process and its products are temperature and residence time. Thermogravimetric analysis was performed as well as the torrefaction process using an electrical furnace on a laboratory scale at a temperature between 250–525 °C. These biomass torrefaction process parameters—residence time and temperature—were necessary to perform the design and construction of semi-pilot scale biomass torrefaction installations with a regimental dryer and a woody and agri-biomass regimental torrefaction reactor to perform a continuous torrefaction process using superheated steam. In the design installation the authors also focused on biochar, a bi-product of biofuel which will be used as an additive for natural bio-fertilizers. Kinetic analysis of torrefaction process using maize and oat straws was performed using NETZSCH Neo Kinetics software. It was found that kinetic analysis methods conducted with multiple heating rate experiments were much more efficient than the use of a single heating rate. The best representations of the experimental data for the straw from maize straw were found for the n-order reaction model. A thermogravimetric analysis, TG-MS analysis and VOC analysis combined with electrical furnace installation were performed on the maize and oat straw torrefaction process. The new approach in the work presented is different from that of current scientific achievements due to the fact that until now researchers have worked on performing processes on oat and maize straws by means of the torrefaction process for the production of a biochar as an additive for natural bio-fertilizers. None of them looked for economically reasonable mass loss ratios. In this work the authors made the assumption that a mass loss in the area of 45–50% is the most reasonable loss for the two mentioned agri-biomass processes. On this basis, a semi-pilot installation could be produced in a further BIOCARBON project step. The kinetic parameters which were calculated will be used to estimate the size of the apparatuses, the biomass dryer, and biomass torrefaction reactor.

Abstract:

The paper is an overview of the results obtained up to date from the combustion and co-combustion activities with Greek brown coal in different installations, both in semi-industrial and laboratory scale. Combustion tests with Greek lignite were realized in three different Circulating Fluidized Bed Combustion (CFBC) facilities. Low rank lignite was burned in a pilot scale facility of approx. 100kW thermal capacity, located in Athens (NTUA) and a semi-industrial scale of 1.2 MW thermal capacity, located at RWE's power station Niederaussem in Germany. Co-combustion tests with Greek xylitic lignite and waste wood were carried out in the 1 MWth CFBC installation of AE&E, in Austria. Lab-scale co-combustion tests of Greek pre-dried lignite with biomass were accomplished in a bubbling fluidized bed in order to investigate ash melting problems. The obtained results of all aforementioned activities showed that fluidized bed is the appropriate combustion technology to efficiently exploit the low quality Greek brown coal either alone or in conjunction with biomass species.

Abstract:

Urban public art is an art exhibition held in public places, contextualized with their surroundings and its audience. Technology is a significant trend in public art due to its connection possibilities with human life, fostering different kinds of interaction. In this way, this work presents an installation proposal consisting of an environment for creating collaborative random music from interaction with mobile devices in public spaces. Everyone participating in the installation is a composer and interaction is a chance agent, although it follows John Cage's composition methods. In order to probe technology, we carried out two pilot studies, followed by a workshop for the installation itself. Those two pilot studies led us to a new version that was put into practice during the workshop. During the workshop, participants' interaction generated fourteen compositions, and the sounds resulting from the collaborative composition were made available to the public through a website.

Abstract:

The modern society is, nowadays, facing two major problems: the energy sources depletion and the degradation of the ecologic system because of wastes rejection. The energetic valorization of wastes contributes on the resolution of both problems. In the present work, a feasibility study of an industrial pilot scale installation for the production of biodiesel from waste grease traps is lead. The installation is meant to transform 1000 tons of fat trap grease per year to biodiesel by transesterification. The daily production of the unit reaches 3200 l of biodiesel. All necessary equipments were sized following process engineering design and based on lab scale optimization experiments. Installation energy balance was also realized and it showed that the energy required for the installation functioning does not exceed 3.5% of the heating value of produced biodiesel.

Abstract:

A new concept of the architecture of hybrid lighting systems for installations of combined lighting is considered. The cascade principle of constructing the optical path of such complexes is described, in which the design contains two stages of the cascade: the upper and lower stages. The upper (input) structure is made on the basis of the corresponding modification of the hollow tube “Solatube®” (daylight), and the lower one, based on the “Solatube®” fibre of a larger diameter, is combined with LED artificial light block and is designed to transmit mixed light (daylight and artificial light). The results of studies on the efficiency of light transmission made it possible to optimize the solution of the new modification of the hybrid lighting complex “Solar LED”, lower stage of the cascade, and to develop the nomenclature of the production line “S”. The description of the first experience of using this complex in the pilot combined illumination system of the “meeting room” in the shopping centre “IKEA Belaya Dacha” headquarters is given. A completely autonomous power supply system for a lighting installation based on solar panels has been implemented.

Full text

Abstract:

ScaleGuard® is a continuous on-line monitor that detects scaling at an early stage when fed with the concentrate of a pilot- or full-scale plant. Scaling is observed in the ScaleGuard before it occurs in the full-scale installation. The ScaleGuard is used to optimize the recovery of two full-scale plants: one reverse osmosis plant treating pretreated surface water and one nanofiltration plant treating anaerobic groundwater. Based on the results of the ScaleGuard the conversion of both the reverse osmosis plant and the nanofiltration plant has been increased from 80% to 82%. The interpretation of the results of the ScaleGuard which was connected with the reverse osmosis plant was not unambiguous. This was due to the mass transfer coefficient decline in the ScaleGuard which could not be attributed to scaling. Results in the nanofiltration plant did not give room for any doubt. In addition, safe supersaturation ratios were derived from experience in pilot- and full-scale plants using anti-scalants for seven sparingly soluble inorganic compounds.

Abstract:

Shading analyzer systems are necessary for selecting the most suitable installation site to sustain enough solar power. Afterwards, changes in solar data throughout the year must be evaluated along with the identification of obstructions surrounding the installation site in order to analyze shading effects on productivity of the solar power system. In this study, the shading analysis tools are introduced briefly, and a new and different device is developed and explained to analyze shading effect of the environmental obstruction on the site on which the solar power system will be established. Thus, exposure duration of the PV panels to the sunlight can be measured effectively. The device is explained with an application on the installation area selected as a pilot site, Denizli, in Turkey.

Abstract:

In Leuven, Belgium, a full-scale pilot plant to test P-recovery from digested municipal wastewater sludge was built in April 2013. This paper illustrates the value of using large-size pilot-plant by explaining the economic evaluation of the installation. The uncertainty analysis of the price per tonne of phosphorus (P) recovered on the basis of the information available during planning is compared with analyses after six months and then two years of operation. It is shown that the most sensitive of the economic model's parameters should determine the size of the pilot-plant.

Abstract:

The freeze–thaw cycle is one of the major sources of damage to granular-surfaced roadways, especially in areas where the timing of heavy agricultural traffic coincides with that of spring thawing. To help local roads agencies plan better for annual budgets and frost embargos, it is useful to be able to predict the frost depth and number of freeze–thaw cycles under a given roadway based on continually updated weather and soil data. Computational modeling can help in this regard, and may be conducted by collecting data on weather and the thermal and hydraulic properties of the soil, as well as soil temperature, moisture, and suction, and using the data directly in the analyses. In order to obtain accurate field data for model calibrations and predictions, an appropriate sensor network and data acquisition system must be carefully planned and installed. This article details the development and installation procedures for one such system of sensors for subgrade temperature, water content, and matric suction, and presents lessons learned throughout the process. Various issues are discussed relating to selection of the sensor and data acquisition system, laboratory and field checks, borehole sensor installation tools, and post-installation troubleshooting and monitoring. To ensure a successful installation beneath the granular roadway, laboratory and field trials were first performed. Salient details of a pilot installation in Hamilton County, IA are provided to guide others developing and scaling similar subgrade sensor systems.

Full text

Abstract:

Among the several options of managed aquifer recharge (MAR) techniques, the aquifer storage and recovery (ASR) is a well-known sub-surface technique to replenish depleted aquifers, which is contingent upon the selection of appropriate sites. This paper explores the potential of ASR for groundwater recharge in the hydrological, hydrogeological, social, and economic context of South Bihar in India. Based on the water samples from more than 137 wells and socio-economic surveys, ASR installations were piloted through seven selected entrepreneurial farmers in two villages of South Bihar. The feasibility of ASR in both hard rock and deep alluvial aquifers was demonstrated for the prominent aquifer types in the marginal alluvial plains of South Bihar and elsewhere. It was postulated through this pilot study that a successful spread of ASR in South Bihar can augment usable water resources for agriculture during the winter cropping season. More importantly, ASR can adapt to local circumstances and challenges under changing climatic conditions. The flexible and participatory approach in this pilot study also allowed the farmers to creatively engage with the design and governance aspects of the recharge pit. The entrepreneurial farmers-led model builds local accountability, creates avenues for private investments, and opens up the space for continued innovation in technology and management, while also committing to resource distributive justice and environmental sustainability.

Abstract:

In a project involving the construction of a new link of European Freeway E18, an 800-mm pipe was to be founded on a cushion of expanded polystyrene under an embankment fill of 9.3 m. In a pilot study measurements were taken of soil-pipe contact earth pressures around the circumference of the pipe, vertical earth pressures in the soil above the crown, relative diameter changes of the pipe in the vertical and the horizontal directions, and pipe settlements into the cushion. The design of the complete structure was partly done by using the active design program SPIDA (Soil Pipe Interaction Design and Analysis). The results indicate that the safety margin in the design was greater than first expected because the reinforced standard pipe, designed for only 5 m of fill, was uncracked, even though the height of fill was 9.3 m. The measured deformations of the pipe were smaller than those expected for the concrete to crack. The earth pressure measurements showed a pronounced soil arching effect in the soil above the pipe.

For meeting the EU standards existing installations have to be upgraded to nutrient removal (nitrogen and phosphorus). One of these installations is the WWTP of the city of Bruges. In the process design phase of the WWTP a pilot study and dynamic modelling are used to optimise the dimensions of the different tanks. To minimise the load overflowing in the collector system it is decided to increase the maximum flow through the WWTP using a storm water regime in the aeration tank.

Abstract:

AbstractThe present paper deals with the classification of the suitability of combined sewers for the installation of heat exchangers and with assessment of the theoretical potential of wastewater in the sewer system for heating of buildings. A classification scheme involving criteria like theoretically available heat, sewer diameter, number of the heat exchanger parallel modules in the sewer cross-section, hydraulic conditions (hydraulic capacity of the sewer, pressurized flow), and potential fouling by biofilm growth was developed. First, individual sewers in the pilot catchment were assessed based on monitoring the flow characteristics and wastewater temperatures and on pipe flow modelling. Second, connectivity of the suitable and partly suitable sewers was examined with respect to the length necessary for the installation of the heat exchanger with the minimum required power of 100 kW. For the continuous sewer sections, the maximum potential power was calculated. The presented approach is generally applicable, however, for other heat exchanger types and other climatic and economic conditions, values of the suitability criteria for the heat exchanger installation must be adapted.

Abstract:

The main objective of the study was to verify the effectiveness of active pedestrian crossings equipped with flashing lights activated automatically by detected pedestrians. A pilot study was conducted in two sites, where speed profiles of vehicles over the distance of 30 m before the crossing were analyzed. The study produced promising results in terms of reducing vehicle speeds so the next study investigated four other unsignalized pedestrian crossings. They were video-recorded for 48 h each, before, after and a year after installation. The ANOVA test was used to check the statistical significance of changes in selected indicators. Even after a year from the installation, the effect of the active signage remained significant. The average percentage of drivers yielding to pedestrians was 77.4% higher and the average waiting time 25.2% lower than before the installation. The average speeds of vehicles were 3.53 km/h lower on collector and 2.60 km/h lower on arterial streets. A decline in the probability of a pedestrian being killed or severely injured (KSI) ranged from 6.3 pp (9.4%) on the arterial streets immediately after the installation up to 12.9 pp (31.7%) on the collector streets one year after.

Abstract:

The use of renewable energies is imperative nowadays. One of the ways to use clean technologies is installation of photovoltaic systems which convert solar energy into electricity, through solar plants. The country?s potential for usage of solar energy is determined by the analysis of climatic conditions. The research is conducted on the example of a small-scale solar plant - a pilot project installed in the city of Nis, concerning the analysis of the mounted system and giving the recommendations for their design with the aim of improving efficient energy use. Limitations in the installation of solar plants can occur in the case of an unfavorable position of the building where the installation is planned, and more often, the limitations are related to the investment costs and length of the repayment period of these kinds of technologies. This paper represents a promotion of sustainable electricity supply for our country and it is in correlation with the legal directives of using renewable energies.

The process in this study was conducted on removal of chromium(III) in a solution simulating a typical spent chrome tanning bath by the resin having matrix of styrene-divinylbenzene-based macroporous sulphonate, Amberjet 1200Na. The column experiments were carried out with the bed volumes of the resin as 751 mL and 1016 mL for different installation systems of the laboratory-scale pilot plant. The feeding solutions in the bed volumes of 200 and 190 were used for each installation system. The regeneration behaviour of the resin was determined by using reverse regeneration procedure with the solution of hydrogen peroxide in alkaline. The regeneration kinetics of the exhausted resin was examined with a range of the solutions having different concentration series of the alkaline hydrogen peroxide. The solutions of the basic chromium sulphate were recycled for each installation system following the regeneration cycles. The chromium ions in effluent were quantitatively eluted, and satisfactory removal of chromium(III) and recovery of chromium(VI) were achieved.

Full text

Abstract:

The goal to decrease greenhouse gas (GHG) emissions is spurring interest in renewable energy systems from time-varying sources (e.g., photovoltaics, wind) and these can require batteries to help load balancing. However, the batteries themselves add additional GHG emissions to the electricity system in all its life cycle phases. This article begins by investigating the GHG emissions for the manufacturing of two stationary lithium-ion batteries, comparing production in Europe, US and China. Next, we analyze how the installation and operation of these batteries change the GHG emissions of the electricity supply in two pilot sites. Life cycle assessment is used for GHG emissions calculation. The regional comparison on GHG emissions of battery manufacturing shows that primary aluminum, cathode paste and battery cell production are the principal components of the GHG emissions of battery manufacturing. Regional variations are linked mainly to high grid electricity demand and regional changes in the electricity mixes, resulting in base values of 77 kg CO2-eq/kWh to 153 kg CO2-eq/kWh battery capacity. The assessment of two pilot sites shows that the implementation of batteries can lead to GHG emission savings of up to 77%, if their operation enables an increase in renewable energy sources in the electricity system.
