BASEL, Switzerland--(BUSINESS WIRE)--Axalta Coating Systems (NYSE: AXTA), a leading global manufacturer of liquid and powder coatings, is supplying its Abcite® thermoplastic powder coating to protect pipes and fittings of Berliner Wasserbetriebe, Germany’s largest municipal drinking water supply company. Berliner Wasserbetriebe supplies drinking water to Berlin’s 3.5 million inhabitants via a complex network of nine waterworks, eight pumping stations and roughly 7,900 km of pipes. Reliable water transport and safety are key issues for drinking water companies, as it is vital for the water to remain safe when it comes out of the tap. The reliable, lasting corrosion protection Abcite provides made it the ideal choice for the new pipes and fittings at the Mariendorf pumping station to the south of Berlin. “As we know, burst water pipes and leaks can have a tremendous financial implication for the water company and for the community as a whole,” noted Michael Cash, Axalta’s Senior Vice President and President of Industrial Coatings. “Abcite, part of Axalta’s extensive global industrial coatings portfolio, can help to prevent corrosion damage and to ensure reliable water transportation. Its use by Berliner Wasserbetriebe showcases Axalta’s ability to provide sustainable, high-performance solutions when there’s much at stake.” Tasked with applying Abcite to the pipes and fittings for the Berliner Wasserbetriebe project was Berlin-based Trapp Infra, who specializes in the production of steel parts for pipelines. “Convincing a customer like the Berliner Wasserbetriebe is not an easy task, but the many advantages of Abcite – its performance, its certification, as well as its many worldwide references – made it an obvious choice. I am sure this is just the first chapter of a long success story for Abcite in Germany,” said Peter Wurl, Trapp Infra’s Managing Director. In use for over 20 years, Abcite has been controlled, tested and certified to the most stringent standards for contact with drinking water, not only in Germany, but also in Belgium, France, the UK and in North America, Australia and New Zealand. Its unique thermoplastic technology creates an impermeable barrier, offers durable adhesion to steel, excellent chemical resistance and minimizes bacterial growth as well as friction loss. Abcite provides outstanding impact resistance, which helps to prevent handling damage, and can be used to coat both the interior and exterior of pipes in one single coating step. Abcite is robust and simple to apply, as it does not require a primer.

IPCC climate change scenarios have a global perspective and need to be scaled down to the local level, where decision makers have to balance risks and investment costs. Very high investments might be a waste of money and too little investment could result in unacceptable risk for the local community. PREPARED is industry driven, 12 city utilities are involved in the project and the RDT carried out is based on the impacts of climate change the water supply and sanitation industry has identifed as a challenge for the years to come. The result of PREPARED will be an infrastructure for waste water, drinking water and storm water management that will not only be able better cope with new scenarios on climate change but that is also managed in a optimal way. We will have complexes monitoring and sensor systems, better integration and handling of complex data, better exploitation of existing infrastructures through improved real time control, new design concepts and guidelines for more flexible and more robust infrastructures. PREPARED will involve the local community in problem identification and in jointly finding acceptable system solutions, that are supported by all, through active learning processes. Activities and solutions in PREPARED will be based on a risk assessment and risk management approach for the whole urban water cycle, through the development of innovative Water Cycle Safety Plans. Other innovations are sensors and models that will enable faster and better actions on changes and new design rules for more resilient design. We will combine European knowledge with valuable knowledge from Australia and the USA, to make the European Water sector more competitive. This to enable our industrial partners to export the products developed in PREPARED to other regions of the world, thus contributing to the Lisbon Goals but also to the MDGs. To ensure this exploitation the PREPARED consortium consist of more than 50% industrial partners and is demand driven.

FORTRESS will identify and understand cascading effects by using evidence-based information from a range of previous crisis situations, as well as an in-depth analysis of systems and their mutual interconnectivity and (inter-)dependency. FORTRESS will seek to intervene in current crisis response practices by bridging the gap between the over-reliance on unstructured information collection on one side and a lack of attention to structural, communication and management elements of cross-border and cascading crisis situations on the other. It will use state of the art information collection and modelling tools to assist stakeholders in evaluating what information is significant, relevant and of greater priority so that they can adjust their actions accordingly. It will do so by using evidence-based information from historical crisis case studies (WPs 2 and 3), as well as comprehensive analysis of the different relationships between systems (WP 4), and systems and sensitivity information from current crisis management contexts and practices in four system simulations (WP 5). This will enable FORTRESS to build a collaborative and accesible, modelling platform for cascading and cross-border effects in a range of crisis situations (WP 6). This will feed into the development of the FORTRESS Incident Evolution Tool (FIET) in WP7; a user-friendly tool with cross-border capabilities that can be used in a cascading crisis. FIET can be used as a foresight tool to assist decision-makers in understanding the potential effects of their decisions in training environments. FIET is also a decision support tool that is user-friendly enough to be employed during a crisis to assist real-time decision making. FIET will be subject to rigorous testing in the field to evaluate its effectiveness, and the project will ensure its user-friendliness by undertaking extensive training with decision-makers to optimise the look and feel of the system (WP 8).

The municipal wastewater in Europe contains a potential chemical energy of 87,500 GWh per year in its organic fraction, which is equivalent to the output of 12 large power stations. Due to the currently applied technologies and related energy loss at each process step, wastewater treatment in Europe today consumes instead the equivalent of more than 2 power stations. Many operators are thus targeting incremental energy efficiency towards energy neutrality, but recent studies have shown that with novel process schemes using existing technologies, sewage treatment plants could actually become a new source of renewable energy, without compromising the treatment performance. The project POWERSTEP aims at demonstrating such innovative concepts in first full scale references for each essential process step in order to design energy positive wastewater treatment plants with currently available technologies. The following processes will be demonstrated in 6 full-scale case studies located in 4 European countries: enhanced carbon extraction (pre-filtration), innovative nitrogen removal processes (advanced control, main-stream deammonification, duckweed reactor), power-to-gas (biogas upgrade) with smart grid approach, heat-to-power concepts (thermoelectric recovery in CHP unit, steam rankine cycle, heat storage concepts), and innovative process water treatment (nitritation, membrane ammonia stripping). These individual technology assessments will merge into integrative activities such as treatment scheme modelling and design, global energy and heat management, carbon footprinting, integrated design options, as well as extensive dissemination activities. POWERSTEP will demonstrate the novel concepts and design treatment schemes of wastewater treatment plants that will be net energy producers, paving the way towards large implementation of such approaches and quick market penetration and supporting the business plans of participating technology providers.

The AquaNES project will catalyse innovations in water and wastewater treatment processes and management through improved combinations of natural and engineered components. Among the demonstrated solutions are natural treatment processes such as bank filtration (BF), managed aquifer recharge (MAR) and constructed wetlands (CW) plus engineered pre- and post-treatment options. The project focuses on 13 demonstration sites in Europe, India and Israel covering a repre-sentative range of regional, climatic, and hydrogeological conditions in which different combined natural-engineered treatment systems (cNES) will be demonstrated through active collaboration of knowledge and technology providers, water utilities and end-users. Our specific objectives are to demonstrate the benefits of post-treatment options such as membranes, activated carbon and ozonation after bank filtration for the production of safe drinking water to validate the treatment and storage capacity of soil-aquifer systems in combination with oxidative pre-treatments to demonstrate the combination of constructed wetlands with different technical post- or pre-treatment options (ozone or bioreactor systems) as a wastewater treatment option to evidence reductions in operating costs and energy consumption to test a robust risk assessment framework for cNES to deliver design guidance for cNES informed by industrial or near-industrial scale expe-riences to identify and profile new market opportunities in Europe and overseas for cNES The AquaNES project will demonstrate combined natural-engineered treatment systems as sus-tainable adaptations to issues such as water scarcity, excess water in cities and micro-pollutants in the water cycle. It will thus have impact across the EIP Waters thematic priorities and cross-cutting issues, particularly on Water reuse & recycling, Water and wastewater treatment, Water-energy nexus, Ecosystem services, Water governance, and DSS & monitoring.

This study exemplifies the use of Life Cycle Assessment (LCA) as a tool to quantify the environmental impacts of processes for wastewater treatment. In a case study, the sludge treatment line of a large wastewater treatment plant (WWTP) is analysed in terms of cumulative energy demand and the emission of greenhouse gases (carbon footprint). Sludge treatment consists of anaerobic digestion, dewatering, drying, and disposal of stabilized sludge in mono- or co-incineration in power plants or cement kilns. All relevant forms of energy demand (electricity, heat, chemicals, fossil fuels, transport) and greenhouse gas emissions (fossil CO2, CH4, N2O) are accounted in the assessment, including the treatment of return liquor from dewatering in the WWTP. Results show that the existing process is positive in energy balance (-162 MJ/PECOD *a) and carbon footprint (-11.6 kg CO2-eq/PECOD * a) by supplying secondary products such as electricity from biogas production or mono-incineration and substituting fossil fuels in co-incineration. However, disposal routes for stabilized sludge differ considerably in their energy and greenhouse gas profiles. In total, LCA proves to be a suitable tool to support future investment decisions with information of environmental relevance on the impact of wastewater treatment, but also urban water systems in general. © 2013 IWA Publishing.

Eight commercially available powdered activated carbons (PAC) were examined regarding organic micro-pollutant (OMP) removal efficiencies in wastewater treatment plant (WWTP) effluent. PAC characteristic numbers such as B.E.T. surface, iodine number and nitrobenzene number were checked for their potential to predict the OMP removal of the PAC products. Furthermore, the PAC-induced removal of UV254nm absorption (UVA254) in WWTP effluent was determined and also correlated with OMP removal. None of the PAC characteristic numbers can satisfactorily describe OMP removal and accordingly, these characteristics have little informative value on the reduction of OMP concentrations in WWTP effluent. In contrast, UVA254 removal and OMP removal correlate well for carbamazepine, diclofenac, and several iodinated x-ray contrast media. Also, UVA254 removal can roughly describe the average OMP removal of all measured OMP, and can accordingly predict PAC performance in OMP removal. We therefore suggest UVA254 as a handy indicator for the approximation of OMP removal in practical applications where direct OMP concentration quantification is not always available. In continuous operation of large-scale plants, this approach allows for the efficient adjustment of PAC dosing to UVA254, in order to ensure reliable OMP removal whilst minimizing PAC consumption. © 2014 Elsevier Ltd.

The competitive impacts of different fractions of wastewater treatment plant effluent organic matter (EfOM) on organic micro-pollutant (OMP) adsorption were investigated. The fractionation was accomplished using separation by nanofiltration (NF). The waters resulting from NF were additionally treated to obtain the same dissolved organic carbon (DOC) concentrations as the initial water. Using size exclusion chromatography (LC-OCD) it could be shown that the NF treatment resulted in an EfOM separation by size. Adsorption tests showed different competitive effects of the EfOM fractions with the OMP. While large EfOM compounds that were retained in NF demonstrated a reduced competition as compared to the raw water, the NF-permeating EfOM compounds showed an increased competition with the majority of the measured OMP. The effects of small size EfOM are particularly negative for OMP which are weak/moderate adsorbates. Adsorption analysis was carried out for the differently fractionized waters. The small sized EfOM contain better adsorbable compounds than the raw water while the large EfOM are less adsorbable. This explains the observed differences in the EfOM competitiveness. The equivalent background compound (EBC) model was applied to model competitive adsorption between OMP and EfOM and showed that the negative impacts of EfOM on OMP adsorption increase with decreasing size of the EfOM fractions. The results suggest that direct competition for adsorption sites on the internal surface of the activated carbon is more substantial than indirect competition due to pore access restriction by blockage. Another explication for reduced competition by large EfOM compounds could be the inability to enter and block the pores due to size exclusion. © 2014 Elsevier Ltd.

A multiresidue method for the simultaneous quantification of 72 micropollutants in aqueous samples by ultra high performance liquid chromatography-high resolution mass spectrometry (UHPLC-HRMS) is described. A variety of substance classes like industrial chemicals, analgesics, anticonvulsants, antihypertensives, psychoactive substances, flame retardants, neutral and acidic pesticides are comprised. A sample volume of 1. mL was enriched by online solid phase extraction (SPE), separated on a 2.6. μm core-shell column and detected with an Exactive™ high resolution mass spectrometer. Simultaneous determination of compounds with different ionization behavior was achieved by polarity switching. One complete run lasted 15. min. The method was validated in the matrices drinking water (DW), diluted surface water (dSW) and diluted waste water treatment plant effluent (dWW) by analyzing 10 replicates spiked at two concentration levels. Limits of quantification (LOQs) ranged between 0.01 and 0.06. μg/L in DW, 0.03 and 0.38. μg/L in dSW, 0.06 and 0.38. μg/L in dWW. The accuracies were between 77 and 117% in DW, 70 and 121% in dSW, 71 and 121% in dWW for both spike levels, respectively. Five compounds in dSW and one compound in dWW were affected by matrix effects, leading to accuracies outside the ranges stated above. The precision for level 2 was excellent with relative standard deviations (RSDs) between 2.2 and 6.5% in DW, 0.5 and 4.9% in dSW and between 1.2 and 6.6% in dWW. © 2012 Elsevier B.V.

PAC adsorption is a widespread option for the removal of organic micropollutants (OMP) from secondary effluent. For an optimal exploitation of the adsorption capacity, PAC recirculation is nowadays a common practice, although the mechanistic interrelations of the complex recirculation process are not fully resolved. In this work, extensive multi-stage batch adsorption testing with repeated PAC and coagulant dosage was performed to evaluate the continuous-flow recirculation system. Partly loaded PAC showed a distinct amount of remaining capacity, as OMP and DOC removals considerably increased with each additional adsorption stage. At a low PAC dose of 10 mg PAC L-1, removals of benzotriazole and carbamazepine were shown to rise from <40% in the first stage up to >80% in the 11th stage at 30 min adsorption time per stage. At a high PAC dose of 30 mg PAC L-1, OMP and DOC removals were significantly higher and reached 98% (for benzotriazole and carbamazepine) after 11 stages. Coagulant dosage showed no influence on OMP removal, whereas a major part of DOC removal can be attributed to coagulation. Multi-stage adsorption is particularly beneficial for small PAC doses and significant PAC savings are feasible. A new model approach for predicting multi-stage OMP adsorption on the basis of a single-stage adsorption experiment was developed. It proved to predict OMP removals and PAC loadings accurately and thus contributes towards understanding the PAC recirculation process. © 2016 Elsevier Ltd.
