Abstract:
Microplastics from sewage and wastewater treatment facilities can be discharged into rivers and oceans, and the treatment facilities themselves can be a point source of microplastic pollution. The microplastic detection status and methods were compared in Miwon, Cheongju, Jecheon, and Chungju sewage treatment facilities in Chungcheongbuk-do. Samples were collected from the inlet, filtration facility, and discharge of Miwon Sewage Treatment Facility, a Porous Substrate Bioreactor (PSBR) construction corporation. Additionally, the inlet, first settling tank, final settling tank and outlet samples were taken from three sewage treatment facilities (Cheongju, Jecheon, and Chungju), which use bioreactor transformation processes. In the results, raw water showed a range of 232-1,510 pieces/L, and effluent water showed a range of 0.7-6.7 pieces/L. All four sewage treatment facilities showed high treatment efficiency of 98.5-99.9%. The treatment processes showed high removal efficiency in the order of CNR (97.0%) > PSBR (95.9%) > NPR (91.5%) > SMART3 (70.3%). As a study was conducted on only one sewage treatment facility for each process, additional research is necessary.

Abstract:
The paper presents the influence of sewage composition on treatment in pilot-scale facility for reject waters (RW) from sewage sludge centrifugation. The facility consisted of mechanical (two tanks with 10 d retention each) and biological parts composed of three subsurface flow reed beds working in batch. Two years of monitoring of the facility proved high efficiency removal of predominant pollutants: chemical oxygen demand (COD) 75–80%, biochemical oxygen demand (BOD) 82.2–95.5% and total nitrogen 78.7–93.9% for low ratio of BOD5/COD in discharged RW. The differences in efficiency removal were correlated with the composition of organics and nitrogen compounds rather than with concentrations. It was assumed that high concentration of colloidal fraction of Org-N and COD in discharged RW led to a decrease in efficiency removal.

Abstract:
The technological process of Galvano-chemical protection, according to qualitatively-quantitative characteristics, represents one of the most complex contaminants in wastewater. A large number of contaminants (metal ions, cyanides, acids, bases, grease and oils, organic solvents, surfactants, phosphates, etc.), found in galvanic wastewater are treated through conventional methods (chemical oxidation and reduction, neutralization, sedimentation, coagulation and flocculation). The reason why galvanic wastewater treatment systems in the Republic of Serbia are conventional is of economic nature. The present study has been undertaken to evaluate the performance of Sewage Treatment Plant located at Aleksinac, Company of "Frad" district which is based on Sequential Batch Reactor process. Performance of this plant is an essential parameter to be monitored as the treated effluent is discharged into the Moravica River. The Performance Evaluation will also help for the better understanding of design and operating difficulties (aeration, blowers, etc.) in Sewage Treatment Plant. Research goal: The efficiency of sewage treatment plants can be illustrated by a study on the evaluation of pollutant levels of the influent and the effluent at the treatment plant of sewage treatment plants discharging into the environment.

Abstract:
Wastewater treatment facility receives, in addition to the influent, the return flow after sewage sludge treatment. Thus, the organic load on the facility increases as well as the nitrogen and phosphorus content load. There was studied the effect of different stages of sewage sludge treatment (sludge thickening, mechanical dewatering, storage on the grit bays and in the gathering ponds) on ammonium nitrogen content in the incoming flow. It is established that the most concentrated water by ammonium nitrogen is the return water from the gathering ponds, but the less concentrated is the supernatant water from sludge lagoons. Taking into account volume of the return flow the secondary ammonium nitrogen load from the every stage of sewage sludge treatment is calculated. It is revealed the seasonal and climatic impact on the gathering ponds return flow composition; it is shown that the biggest fluctuations occur in spring-summer period. The dependence of ammonium nitrogen content in the return flow on sludge thickening process time in the sludge lagoons is determined. The load contribution on the treatment facility by ammonium nitrogen in the return flow was 3% in the relation to this in the influent. The conclusion was made that with the existing technology of sewage sludge treatment the isolated scheme of return water treatment is not required. The comparative analysis on the effect of thermophilic and mesophilic conditions of anaerobic sewage sludge treatment on ammonium nitrogen content in the liquor was carried out. It was found that the higher ammonium nitrogen secondary load is created by the liquor of thermophilically treated sewage sludge: it is 16,4% versus 11,8% of mesophilically treated. Hence, the including of anaerobic sewage sludge treatment in the scheme significantly increases the load on treatment facility by ammonium nitrogen. In the conditions of cascade denitrification the distribution of incoming in the denitrification zones water flow is of great importance for providing required content of readily available organic substances. The change of ammonium nitrogen content in this flow will require the adjustment of its volume.

The paper states that operating sewage pumping station always goes together with high electrical energy consumption, even if most suitable sewage pumping is used. Under conditions of strongly marked land forms with height difference the authors suggest using the so-called “continuity of stream” and claim that it would result in short-term work of water-pumping sets. This method would allow to enlarge water-pumping sets overhaul period and to reduce energy costs. The paper introduces practical results obtained while operating a certain sewage facility. These results make possible to calculate the efficiency of the introduces method of clean water runoff pumping.

Abstract:
About 80 percent of the water supplied to consumers in Indian cities gets converted into sewage. The metros, major cities and towns together generate about 20,000 million litres of wastewater (sewage) per day. About 50 to 70 percent of the pollution load of rivers and streams is from domestic sewage. Sources of fresh water are getting exhausted and development of new water resources is cost intensive and time consuming. Since water stored in dams and lakes is the main source of water for urban population, it is to be conserved, collected after its use and treated before it is discharged into the nearby water bodies. Sustainable development is necessity of the present world for every industry. Wastewater treatment industry is not an exceptional for this; in fact it is primary need for conservation of natural water sources. To prevent the degradation and to maintain the quality of water in the rivers, the sewage generated from cities is to be treated before its disposal into the nearby river. The treated sewage can be used for secondary purposes like gardening, agriculture, industrial reuse and recreational fields. The paper discusses the integrated approach in decentralised planning, designing and execution of new sewage treatment plants of Pune and Pimpri-Chinchwad Municipal Corporation for sewage treatment and disposal.

Abstract:
Nowadays, risk management applies to every technical facility, branch of the economy, and industry. Due to the characteristics of the analyzed wastewater treatment plant and the specificity of the used processes, one must approach different areas individually. Municipal sewage treatment plants are technical facilities; they function as enterprises and are elements of larger systems—water distribution and sewage disposal. Due to their strategic importance for the environment and human beings, it is essential that they are covered by risk management systems. The basic stage of risk management is its assessment. On its basis, strategic decisions are made and new solutions are introduced. Constant monitoring of the operation of a treatment plant allows for assessment of whether actions taken are correct and whether they cause deterioration of the quality of sewage. In our work, we present a method of risk assessment based on historical data for an existing facility and obtained results.

Abstract:
碩士<br>逢甲大學<br>會計所<br>100<br>Water resources management is very important topic of discussion today as environmental protection consciousness awakening among the citizens and water resources depleting at an alarming speed. Specifically, waste water and sewage treatment are the top issues that are commonly discussed in today’s medias. Although our country’s cost accounting system of wastewater and sewage treatment has adopted activity-based costing, the system is not updated regularly and therefore it could result in unrealistic cost allocations. Because of cost effectiveness consideration enterprises generally do not voluntarily consider installations of wastewater and sewage treatment facilities. As technology advances the Economic Value Added deriving from installations of such facilities is very likely to bring long-term values to the enterprises. This study focuses on a Taiwanese private university that voluntarily installed wastewater and sewage treatment facilities and used it as a case study. Research objectives include building of a model to calculation the costs associated with the installation of wastewater and sewage treatment facilities and using the model to perform a cost-benefit analysis.

Abstract:
Abstract Palo Verde Nuclear Generating Station, operated by Arizona Public Service Company, is comprised of three 1,270 MW pressurized water reactors. The plant site is 55 miles west of Phoenix, Arizona, in the Sonoran desert. The Water Reclamation Facility is an on-site, 90 million gallon per day tertiary treatment plant, that receives secondary treated sewage from the cities of Phoenix and Tolleson. The plant operating license requires zero water discharge from the site. Evaporation ponds collect and detain tower blowdown and other non-radioactive wastewater streams. Original guidelines for wastewater flow to the evaporation ponds consumed available volume at an accelerated rate. Expenditures associated with constructing more ponds were expected but undesirable. An aggressive project to solve the problem produced alternate approaches to water management. Water mass balance computer modeling, based on experimental and empirical data provided guidelines for splitting the tower blowdown stream between final wasting to the evaporation ponds and through the tertiary treatment plant for reprocessing. Tower chemistry control based on saturation index values for specific scaling species, in conjunction with water balance constraints, have provided positive control in maintaining and reducing evaporation pond levels.

Abstract:
Abstract For years nickel-based and cobalt-based alloys have been used to help control corrosion and wear in the chemical process industries. Today, as environmental concerns increase, the use of high alloys in industrial and hazardous waste treatment facilities for solving chronic materials problems is increasing. Such high alloys help to ensure safe and reliable equipment operation while often times reduce maintenance and down-time costs. Field testing of Ni-and Co-based alloys in waste treatment applications are discussed. Examples are provided to highlight applications in incinerator off-gas scrubber components, acid reclamation vessels, sewage and municipal waste treatment facility components and acid waste hauler corrosion liners. Typical modes of failure of low alloys due to the existence of aggressive conditions in these applications are referenced. Prototype construction and service performance of critical equipment made from high alloys help justify their use. Meaningful corrosion data and/or prototype field performance can be utilized to determine estimated life-cycle costs which include not only capital expenditure of the equipment but also expected downtime, maintenance and replacement costs. Specifically, case histories involving UNS N06022; nominally 57Ni-22Cr-13Mo-3W-3Fe and UNS NO6030; nominally 43Ni-30Cr-5Mo-2W 15Fe will be reviewed. In addition to these two Ni-based alloys, a cobalt-based alloy (nominally 53Co-26Cr-9Ni-5Mo-2W-3Fe, designed to resist both corrosion and wear, will also be presented. The technical merit and cost effectiveness of these high alloys in comparison to other alloys (Table 1) will also be discussed.

Abstract:
Abstract Passaic Valley Sewerage Commission (PVSC) manages the sixth-largest wastewater treatment plant in the U.S., processing up to 350 million gallons per day (MGD) at peak flow. To restore the degraded condition of the facility’s clarifiers, PVSC administered a test program to evaluate the performance of concrete repair and coating alternatives. Five protective coatings were subjected to intensive, side-by-side testing for periods up to eight to twelve months to test for delamination in multicoat systems, pinholes, holidays, and adhesion in an active setting. Three of the participating manufacturers scored the minimum ranking of eight on a scale of ten. With one manufacturer pulled from the study, two coatings in total were approved and specified. Of the two specified, one product scored the highest possible rank—the only product that could be applied without a resurfacing material and could be sprayed up to 500 mils in a single coat. Applied to PVSC’s infrastructure, the quick cure epoxy offered structural enhancement and long-term protection to prevent concrete degradation. This project emphasizes the importance of testing coatings under live field conditions to better understand their long-term performance instead of solely relying on a product’s technical data sheet (TDS) that only reflects laboratory testing.

Abstract:
The Pinellas County Resource Recovery Facility (PCRRF) is a 3,150 tons per day mass burn facility located in Pinellas Park, Florida. Due to local water use restrictions and increasing costs for potable water supplies in central Florida, Pinellas County has continuously sought to reduce potable water usage at its facilities. The PCRRF’s boiler makeup water system represented a prime target. Accordingly, a makeup water pre-treatment system using reclaimed water from a sewage treatment plant as its source, has been installed upstream of the existing reverse osmosis membrane and mixed bed polishing demineralizers. The pre-treatment system consists of a micro-filtration module, followed by a reverse osmosis module, which results in an overall configuration of micro-filtration, two stage reverse osmosis, and polishing demineralization. The system has been operational for approximately six months, and is producing excellent quality makeup water for the facility boilers. This paper will describe the pre-treatment process and its operational results to date.

Abstract:
Efficient utilization of biomass by a cogeneration system (CGS) is a promising technology for promoting sustainable energy development. Sewage treatment plants are facilities that have been continuously producing biogas by anaerobic digestion. Thus, the potential of a biogas-fuelled CGS in a sewage treatment plant is estimated to be very high. However, there have been few reports on the performance of a biogas-fuelled CGS, particularly regarding the effect of ambient temperature on its performance, and the most efficient arrangement of a biogas-fuelled CGS remains unknown. In this study, performance of a biogas-fuelled CGS was simulated under three typical ambient temperature (low, medium and high) conditions using actual data for a CGS with a micro gas turbine. In the beginning of this study, the relation of energy balance of the plant and ambient temperature was clarified. It was found that the amount of heat demand is ambient temperature-dependent but that the amount of biogas fuel produced is almost constant throughout the year. When a boiler is replaced with a biogas-fuelled CGS to utilize the biogas, under a high temperature condition, the CGS is not able to fully utilize all of the biogas produced, and therefore another pathway of biogas utilization is needed. Under a medium temperature condition, a gas storage system is needed for using biogas efficiently. However, some of the biogas still cannot be utilized efficiently. Under a low temperature condition, since ambient temperature varies greatly between summer and winter, the amount of heat demand of the plant also varies greatly throughout the year. This leads to an imbalance in biogas production and heat demand, and therefore attention must be given to energy management in this condition. The combination of other auxiliary equipment such as a boiler, heat pump and gas storage with the CGS is required in order to cover the total heat demand throughout the year. Four possible arrangements of the CGS with different auxiliary components were proposed and their performances were compared. It was found that all of the proposed CGS arrangements can sufficiently cover the total heat demand by only using biogas produced in the facility. Compared to the conventional system, all proposed CGS arrangements can reduce electrical power demand by 23∼28%, recover 74∼77% of the energy of biogas produced, and utilize almost 100% of the biogas produced. The arrangement with a heat pump is more efficient than the arrangement with a boiler. It was also found that excess biogas in summer can be used in winter by storing the biogas. Thus, a CGS arrangement that includes a gas storage system will enable efficient utilization of biogas and recovered exhaust heat.

Abstract:
A combined sewer system is a facility that collects both municipal sewage and surface runoffs. These facilities may overflow (combined sewer overflow or CSO) during large storms which results in serious pollution, i.e. the flows exceed the capacity of the treatment plant. An approach to reduce the number of combined sewer overflows is to store rainfall runoffs temporarily [1]. The Treatment Shaft system is a relatively new but proven patented technology (U.S. Patent [2] and other patents) that includes the necessary CSO control and treatment, with less footprints than existing systems, and at a reduced cost. In this system, wastewater is collected in a large shaft equipped with baffles and partitions designed to ensure a very slow velocity within the system. In this study, the efficiency of the Treatment Shaft system for separation of solid contents without the use of flocculation agents is investigated. Moreover, the effect of geometry modifications on the separation efficiency is evaluated. For this purpose, a Computational Fluid Dynamics (CFD) approach for multiphase flow of particulate wastewater is used to evaluate the performance of various Treatment Shaft designs for a 10-year, 1-hour rainstorm event. It is shown that the Treatment Shaft is an effective technology to separate particles larger than 175μm, and more than 50% of the particles of size 175μm or more are settled. Additionally, several design variations are assessed and a design with a less footprint is specified.

Abstract:
Addressing environmental challenges while improving social and economic conditions calls for innovative solutions. One of those challenges is the management of organic waste, which if left untreated can lead to water pollution, greenhouse gas emissions, and soil degradation. Brazil produces substantial amounts of organic waste due to its sizeable population and extensive agricultural production. As one of the largest economies in the Global South, the development of innovative solutions to organic waste management in Brazil can potentially pave the way for their adoption in other countries within the Global South. Biogas systems are solutions for organic waste treatment that simultaneously make use of the energy content, reduce gas emissions, and facilitate nutrient recycling. Nevertheless, their multifaceted nature also entails numerous barriers to their widespread implementation. Thus, this report explores the barriers to the development of biogas systems in Brazil and possible strategies to overcome these.Diverse data collection methods were used in the study. A literature review helped identified overall barriers to biogas systems development. This was followed by a field study in Brazil, involving visits to biogas facilities and interviews with stakeholders. The results were combined to understand the impact of the identified barriers across sectors. Finally, a workshop with Brazilian and Swedish stakeholders helped validate the findings and explore possible strategies to overcome barriers to biogas systems development.In the report barriers across eight categories are discussed, namely technological, economic, market, regulatory, cultural, environmental, network, and biomethane barriers. Technological barriers include lack of specialized knowledge, which leads to challenges in operation and maintenance of biogas reactors. Another type of technological barrier is limited access to infrastructure such as gas pipelines and sewage networks, which leads to technical challenges regarding both substrate supply and gas handling. High initial investments and funding accessibility are the most prominent economic barriers. Market barriers include competition with cheaper waste treatment solutions, lack of structured markets for biogas, and limited access to markets. The absence of a national biogas-specific policy, spatial diversity in state-level regulations; together with few and isolated incentives for biogas production are the major regulatory barriers. Cultural barriers include limited knowledge among society and substrate holders about biogas benefits, resistance to waste segregation practices, and sectoral structures hindering collaboration across the biogas value chain. Although environmental aspects of biogas systems are usually drivers to the implementation of biogas facilities, concerns such as gas leaks, odors, and soil contamination risks associated with poor facility design and performance are environmental barriers. Network barriers stem from limited platforms for discussion and interaction among actors, ultimately delaying the establishment of a unified national agenda for biogas development. Due to its characteristics, the production, distribution, and utilization of biomethane face additional challenges across various barrier categories, with major obstacles including uncertainties in grid injection contracts and infrastructure, as well as the expectation that biomethane prices should match those of natural gas.To overcome some of the barriers presented above, the study explored two strategies that could be pursued by actors interested in biogas systems development in Brazil. First, biogas cooperatives are proposed as one solution, allowing resource pooling for technology investment and enhanced biogas production. Second, dedicated biogas producers could play a crucial role,viparticularly in addressing financing challenges and ensuring efficient operation. Dedicated biogas producers could improve the technical efficiency and environmental performance of biogas facilities. Options for biogas utilization include electricity generation and biomethane production, with the latter offering tax benefits and reduced transportation costs when producers can use the biomethane for transportation themselves.The report highlights barriers across various dimensions and addresses strategies to overcome these barriers, such as biogas cooperatives and dedicated biogas producers. Future research could focus on testing these strategies in the Brazilian context through case studies, pilot projects, and collaborative initiatives to refine interventions and accelerate the adoption of biogas technologies.
