Full textAbstract:
Micro-bubbles are used in electro-flotation (EF) and dissolved air flotation (DAF) for particle separation. The efficiency of these flotation processes depends on the collision of bubble and particle and the collision efficiency is affected by certain parameters with respect to the size and zeta potential of bubble and particle. Therefore, it is necessary to monitor not only the zeta potential of the particle, but also that of the bubble. Gas bubbles are reported to be generally negatively charged in water. In this paper, we report a study performed to measure the zeta potential of bubbles in solutions containing divalent metals and find factors which can produce positively charged bubbles. Calcium and magnesium ions were selected as divalent metal ions because natural water normally contains an appreciable quantity of them. It was found that bubbles are negatively charged in CaCl2 solutions whereas, under certain conditions, they become positively charged in MgCl2. Charge reversal of bubbles was observed above 10-2 M Mg, especially above pH 9. A probable principle that explained the charge reversal could be a combined mechanism with both specific adsorption of hydroxylated species and formation of hydroxide precipitates. Creating solution conditions that can produce positively charged bubbles in flotation methods might make it possible to remove particles using lesser amounts of coagulant or even none at all.

Full textAbstract:
Organic and inorganic micropollutants are rejected by high-pressure membranes, nanofiltration (NF) and reverse osmosis (RO), primarily as a consequence of solute–membrane interactions. These interactions include steric and electrostatic effects that depend on compound properties (e.g., molecular weight (MW) and ionic charge) and membrane properties (e.g., molecular weight cutoff (MWCO) and surface charge (zeta potential)), with the added influence of membrane operating conditions (e.g., recovery). This paper summarizes the rejection trends by several NF and RO membranes for a wide range of organic micropollutants based on hydrophobicity/hydrophilicity (octanol-water partition coefficient, KOW) and charge (neutral or negative), and a more narrow range of inorganic micropollutants in the form of oxyanions (chromate, arsenate and perchlorate) of varying MW and charge. While RO provided greater rejections of micropollutants than NF, observed NF rejections were, in many cases, significant. For oxyanions, rejection was mainly influenced by ionic charge and MW. RO properties generally had little influence while MWCO and zeta potential were both significantly influential for NF. For organic micropollutants, with exception of RO versus NF classifications, membrane properties were less influential than compound properties with greater rejections generally observed with increasing MW, KOW, and (negative) charge.

The measurement of surface charge has long been proposed a convenient way to optimise coagulant dosage in water treatment processes. In the UK there has been a renewed interest in the use of charge measurement in the form of both zeta potential and streaming current for controlling coagulation and filtration processes. This paper review current knowledge on the factors effecting charge measurement and using data collected from a sampling survey of 12 UK water treatment works identified windows of optimum charge for sedimentation, flotation and filtration processes.

Full textAbstract:
H2SO4 has an effect on the sorption of organic contaminants by coking coal (CC) in wastewater. This paper focused on the effect of pH on the removal of chemical oxygen demand (COD), phenols and ammonia. UV-vis spectra, Fourier transform infrared spectra, zeta potential and Brunauer, Emmett and Teller (BET) analysis were investigated to characterize the changes of CC properties and coking wastewater (CW) at different pH values. The results showed that the COD and phenol removal efficiencies increased with decreasing pH value, while the ammonia removal efficiency was decreased gradually. A new transmittance band in the region of 340–600 cm−1 was observed in UV-vis spectra of CW in acidic condition. The absolute value of the zeta potential as the solution was gradually increasing with the increasing of pH value. Surface area and total pore volume of CC which was immersed in acidic solutions measured by BET were much higher than that of raw CC. CC has a greater adsorption capacity to organic pollution in the acidic solution mainly by van der Waals forces and hydrogen bonding.

Full textAbstract:
The paper presents an overview and discussion on the link between natural organic matter (NOM) character and its treatability by coagulation. Trials were conducted on a series of bench scale and pilot plant trials on three source waters: two from UK moorland catchments and one from a US snow melt source. Overall the work demonstrates the importance of the polarity balance and the charge density of the NOM contained within the source water. The hydrophobic content controls the coagulant demand such that variation in the demand between sources or sampling periods can be accounted for by changes in the hydrophobic content and its charge density. The raw water hydrophilic content, and specifically the nonacid fraction, provides a useful indicator of the achievable residual. Analysis of coagulation performance revealed a clear relationship between zeta potential and residual DOC. For each source an operational zeta potential range exists within which the residual concentration is optimal. Comparison of the ranges achieved during each trial demonstrated that a communal range between −10 and +3 mV exist for all waters thus providing a useful guide range for operational control.

Future, flexible thermal energy conversion systems require new, demand-optimized high-performance materials. The High performance Ferritic (HiperFer) stainless steels, under development at the Institute of Microstructure and Properties of Materials (IEK-2) at Forschungszentrum Jülich GmbH in Germany, provide a balanced combination of fatigue, creep and corrosion resistance at reasonable price. This paper outlines the scientific background of alloy performance development, which resulted in an age-hardening ferritic, stainless steel grade. Furthermore, technological properties are addressed and the potential concerning application is estimated by benchmarking versus conventional state of the art materials.

Full textAbstract:
Charge neutralisation is an important mechanism in (polyelectrolyte) conditioning of biotic sludges and required for efficient sludge dewatering. Based on results from streaming potential and zeta potential measurements, it has been suggested that charge neutralisation is more complete on the outside of the sludge flocs than on the inside. This paper discusses the development of a technique for assessing the spatial distribution of polyelectrolyte (PE) within sludge flocs. After flocculation with a fluorescently labelled PE, fluorescence microscopy can be used to visualise the distribution of the PE in the sludge flocs. Preliminary results indicate that the PE can penetrate relatively deep into the sludge flocs (and flocculi). Inhomogeneity in the PE distribution arises from differences in exposure to PE in different regions, and from differences in the affinity of the PE for different substances.

The paper describes the investigation of how the make up of raw water influences the physical properties of flocculated suspensions. The work focuses on the properties of four characteristic organic fractions separated as a function of their hydrophobicity. Mesoscale data indicates that the hydrophobic fractions dominate the make up of the water and are the most easily removed. Microscale and nanoscale data reveals that the fulvic acid fraction (FAF) generates statistically smaller and more compact flocs than those formed by the other fractions and the hydrophilic fractions form the most internally open and dendritic structures. The FAF fraction was also seen to dominate the zeta potential response of the raw water.

Full textAbstract:
In light of global warming mitigation efforts, increasing sludge disposal costs, and need for reduction in the carbon footprint of wastewater treatment plants, innovation in treatment technology has been tailored towards energy self-sufficiency. The AB process is a promising technology for achieving maximal energy recovery from wastewaters with minimum energy expenditure and therefore inherently reducing excess sludge production. Characterization of this novel sludge and its comparison with the more conventional B-stage sludge are necessary for a deeper understanding of AB treatment process design. This paper presents a case study of a pilot-scale AB system treating municipal wastewaters as well as a bio- (biochemical methane potential and adenosine tri-phosphate analysis) and physico-chemical properties (chemical oxygen demand, sludge volume index, dewaterability, calorific value, zeta potential and particle size distribution) comparison of the organic-rich A-stage against the B-stage activated sludge. Compared to the B-sludge, the A-sludge yielded 1.4 to 4.9 times more methane throughout the 62-week operation.

ABSTRACTThis is a cross institution project involving four Institutes of Technology in Ireland. The objective of this project is to assess the use of technology to enhance the assessment of laboratory sessions in Science and Health. In science, health and engineering, the laboratory sessions are at the core of the learning process for skill development. These laboratory sessions focus on the skills acquisition. The Irish Institute of Technology sector, in particular, develops these skills and considers them essential for ‘professionally ready’ graduates. In terms of student progression and retention, the assessment structure has been identified as having a significant impact on student engagement.The Technology Enhanced Assessment Methods (TEAM) project led by Dundalk Institute of Technology and partnering with Institute of Technology Sligo, Athlone Institute of Technology and Institute of Technology Carlow is exploring the potential offered by digital technologies to address these concerns. It aims to develop a framework for applying the principles of effective assessment and feedback to practical assessment. The TEAM project also aims to facilitate dialogue among stakeholders about what it is we want student to learn in laboratory sessions and how our assessment can facilitate this. A peer network of discipline-specific academics and students in the Science and Health field has been established across all four Institutes. As the network focuses on authentic skills assessment in all core modules, including physics and chemistry, the best practice from this project will inform future assessment procedures across laboratory sessions and may be considered for application within a Science and Materials Engineering context.Assessing the skills acquired in this environment takes many forms. Using student and stakeholder feedback along with an extensive literature review of the area, the team identified key technologies that cut across science and health disciplines, with the potential to influence and enable the learning process. The emphasis was on developing a powerful learning environment approach to enable students to deepen their learning through engagement with the process. The areas identified are: (i) Pre-practical preparation (videos and quizzes), (ii) Electronic laboratory notebooks and ePortfolios, (iii) Digital Feedback technologies and (iv) Rubrics).This paper describes the student experience and perceptions of the adoption of digital technology in science practical assessments. It also describes the process involved in setting up the pilot structure and it presents the initial results from the student survey.

Academic institutions present a unique opportunity for anaerobic digestion (AD) projects in that they have a concentrated population that generates waste, utilizes heat and electrical power, and often are motivated to implement sustainability initiatives. However, implementation of AD on college campuses in the U.S. is only beginning to emerge and data required to size and operate digesters are limited. This paper provides formulae to estimate food waste generated at college and university campuses base upon data collected at the Rochester Institute of Technology. Bottom-up and top-down estimates are presented and results are compared to an extensive review of publicly available data from other colleges and universities. The bottom-up methodology resulted in a lower estimate (18 kg food waste/enrolled student) than the top-down estimate (29 kg/enrolled student). Both were significantly lower than the estimate previously reported in the literature (64 kg/enrolled student). Bench-scale co-digestion experiments of the food waste with dairy manure resulted in a methane yield of 437 ml CH4/g VS. Applying this methodology to only 4-year colleges in New York State has the potential to generate 27 million GJ of energy from food waste.

Autistic Spectrum Disorder (ASD) is a developmental disability, which can affect communication and behavior, causing significant social, communication, and behavior challenge. From a rare childhood disorder, ASD has evolved into a disorder that is found, according to the National Institute of Health, in 1% to 2% of the population in high income countries. A potential early and accurate diagnosis can not only help doctors to find the disease early, leading to a more on time treatment to the patient, but also can save significant healthcare costs for the patients. With the rapid growth of ASD cases, many open-source ASD related datasets were created for scientists and doctors to investigate this disease. Autistic Spectrum Disorder Screening Data for Adult is a well-known dataset, which contains 20 features to be utilized for further analysis on the potential cause and prediction of ASD. In this paper, we developed an Autism classification algorithm based on logistic regression model. Our model starts with featuring engineering to extract deep information from the dataset and then applied a modified logistic regression classifier to the data. The model can predict the ASD in an average F1 score of 0.97, which displays the superiority and feasibility of the proposed model. Besides, the data visualization technique was used to displays several feature distributions images for people to better understand the data and related feature engineering.

Full textAbstract:
Abstract The use of aerial robotic systems that physically contact oil and gas structural assets to obtain measurement data in offshore and marine environments carries unique challenges and operational variables. The objectives of this paper are to demonstrate, with examples, how these aerial robotic systems afford safer, cheaper, and better nondestructive testing (NDT) measurement collection methodology and allow more robust insight into assets conditions than the slower, less safe, and more expensive manual method. To take NDT measurements such as Ultrasonic Wall Thickness (UT) Measurements at height, currently one needs to utilize a lift, ladders or other solutions to reach areas on certain assets. This can be both dangerous, due to the possibility of falls, and time consuming. Utilizing an aerial robotics platform for contact based (not visual) NDT measurements such as Ultrasonic Thickness (UT) allows workers to remain safely on the ground. Drones, with robotic arms, have the potential to improve inspection, testing and data collection. This paper explores an aerial robotic system that flies up to a structure with a metal sub-straight, then under full autonomous software control, touches a UT measurement probe to the target and records the measurement data compliant with American Petrolium Institute (API) and other standards. The use of aerial robotics systems for NDT is still a new and novel application utilizing existing technologies such as electronic measurement readers, drones, etc. with a system of complex integrations that allows for a better application of science. Aerial Robotic NDT systems have the potential to improve the inspection, testing and data collection aspects of coated and uncoated assets, in part, by making the NDT measurement process easier and safer thus allowing for more frequent measurements and/or a larger quantity of measurement samples. When possible, working at heights should be eliminated as part the hierarchy of fall protection stipulated by both OSHA and ANSI. For this reason alone, the use of aerial robotic systems is important now and in the immediate future Oil & Gas infrastructure, including Offshore. This paper intends to provide readers an awareness of this new technology as well as provide information about its efficacy, limitations and operational requirements.

Despite the fact that the invention of the fuel cell is more than 160 years old, the fuel cell industry today is still in its infancy. While there are many large companies active in the industry, it is, for the most part, dominated by many small and startup companies focused on the design and development of fuel cell systems. Relatively little attention has been given to the cost effective high-volume (i.e., automated) manufacture of the resulting systems and components. If the wide spread commercial use of fuel cells is to become a reality, and we are to realize the potential benefits to our environment and mankind it is essential that we also put the appropriate level of attention on the enabling manufacturing technologies. Celanese Ventures GmbH is a “new venture” arm of Celanese AG, located in Frankfurt, Germany. They are focused on developing the market for their high temperature polybenzimidazole (PBI®)-based membrane material for use in Proton Exchange Membrane (PEM) fuel cells. Several years ago Celanese realized that the best way to ensure the market for their membrane material is to develop the capability to produce complete membrane electrode assemblies (MEAs) that can be incorporated into fuel cell systems being developed by other companies. Furthermore, such value-added processing can be economically advantageous. This paper will describe the multi-phased collaboration between Celanese, the Flexible Manufacturing Center (FMC) located at Rensselaer Polytechnic Institute (RPI), and Progressive Machine and Design (PMD) to develop a fully automated high temperature MEA pilot manufacturing line that began operation in September, 2002. The FMC has and continues to serve in a unique role for a university research center. The FMC has been involved in the concept development, laboratory proof of principle, acquisition management, technical representation during the design, build and implementation phases, and the ongoing optimization of and improvements to the operational pilot line. We will describe the unique properties of the high temperature PBI® membrane and the benefits of this form of membrane in PEM fuel cell operations. The specific role of the FMC during each phase of the project will be highlighted, and a description of the resulting pilot line will be provided. Finally, we will discuss the important role that effective technology transfer plays in a project with the magnitude and complexity described herein.

Full textAbstract:
Over time, robots degrade because of age and wear, leading to decreased reliability and increasing potential for faults and failures; this negatively impacts robot availability. Economic factors motivate facilities and factories to improve maintenance operations to monitor robot degradation and detect faults and failures, especially to eliminate unexpected shutdowns. Since robot systems are complex, with sub-systems and components, it is challenging to determine these constituent elements’ specific influence on the overall system performance. The development of monitoring, diagnostic, and prognostic technologies (collectively known as Prognostics and Health Management (PHM)), can aid manufacturers in maintaining the performance of robot systems by providing intelligence to enhance maintenance and control strategies. This paper presents the strategy of integrating top level and component level PHM to detect robot performance degradation (including robot tool center accuracy degradation), supported by the development of a four-layer sensing and analysis structure. The top level PHM can quickly detect robot tool center accuracy degradation through advanced sensing and test methods developed at the National Institute of Standards and Technology (NIST). The component level PHM supports deep data analysis for root cause diagnostics and prognostics. A reference data set is collected and analyzed using the integration of top level PHM and component level PHM to understand the influence of temperature, speed, and payload on robot’s accuracy degradation.

Full textAbstract:
In late 2004, the pilot Solzinc solar reactor was commissioned. The European Union and the Swiss Federal Office of Science and Education are funding this project to demonstrate the technical feasibility and the economical potential of producing Zn by reducing zinc oxide with the aid of concentrated solar energy and a small amount of carbon at a close to industrial scale. The zinc can be used as a means to store solar energy in a chemical way, e.g. suited to release electricity in Zinc-air fuel cells. This allows on demand use, boosting the availability of solar energy. Furthermore, as the Zinc-air fuel cells’ waste is ZnO, we get a cyclic process by reducing this ZnO in the Solzinc solar reactor. Numerous lab tests and numerical studies of the chemical and thermal behavior of the solar carbothermic ZnO reduction process were conducted by the Swiss Paul Scherrer Institute, the Swiss Federal Institute of Technology, the Israeli Weizmann Institute and the French CNRS Processes, Materials and Solar Energy laboratory. An indirectly heated beam-down reactor concept was chosen and influencing parameters, such as the type of carbon, the stoichiometry of the ZnO-C mix and the process temperature were explored. Based on these findings the technology was scaled up for the pilot plant for about 0.25 MW solar input leading to a designed zinc production rate of 50kg/h. The Swedish company ScanArc Plasma Systems AB developed a special quench system to produce zinc dust directly from the gaseous zinc exhausted from the solar reactor. The dust’s characteristics were adapted to the requirements of the Zn-air fuel cells developed by the German company ZOXY Energy System AG. The resulting zinc can be easily stored and transported for generating electricity as needed. In 2004, the pilot reactor, the quench system and extensive instrumentation were installed at the Weizmann Institute’s solar facilities to process batches of up to 500 kg of ZnO-C mixture. After cold testing of the installation and fulfilling all safety requirements, the first batches were processed. This paper explores the results of the commissioning to show the technical feasibility of this process to produce zinc and to store solar energy.

Recently, the prospects of virtual laboratory environments developed using commercial multi-player computer game engines and their associated software development kits for providing undergraduate engineering and science students with engaging and interactive laboratory experiences have started to be explored. There is a strong potential for such virtual laboratory environments to be readily accepted by today’s students who are accustomed to using advanced communication and entertainment technologies. While online laboratories based on either remotely operated hardware or pure software simulations are often criticized for lacking student interactivity and for being limited to the data collection and result analysis aspects of traditional hands-on laboratories, these shortcomings can be overcome with virtual laboratory environments implemented based on multi-player computer game engines. For instance, game engines allow one to include into the experimental procedure the assembly process of the experimental setups before carrying out any data collection. Furthermore, such virtual laboratory environments can facilitate and even force certain interactions by the students of a laboratory group. This paper discusses recent developments at Stevens Institute of Technology (SIT) that enable students to assemble laboratory equipment inside a virtual laboratory environment implemented using the “Source” game engine (1) and “Source” software development kit (2). In this environment, the students can interactively select and assemble components of laboratory hardware into complete experimental setups, which are subsequently used in experimental procedures. This assembly process can be performed in a cooperative fashion with multiple students collaboratively interacting with each other as well as with the experimental equipment. Such game-based educational tools are expected to find applications for teaching and training in a wide array of fields.
