  • Water Treatment Optimization - Case Study

    Drinking water treatment in North America has stringent requirements for effluent water quality, with a great amount of attention being drawn to the presence of hazardous disinfection by-products (DBPs) persisting through water distribution systems. The operation of water treatment plants involves addition of various mixing agents to help with coagulation and settling of organics in the raw water ...

  • Impact of European Water Framework Directive Article 7 on Drinking Water Directive compliance for pesticides: challenges of a prevention-led approach

    Article 7 of the European Water Framework Directive (WFD) promotes a prevention-led approach to European Drinking Water Directive (DWD) compliance for those parameters that derive from anthropogenic influences on raw water quality. However, the efficacy of pollution prevention interventions is currently uncertain and likely to be variable, which makes absolute compliance with the drinking water ...

  • Determination of Bisphenol A in Drinking Water

    A comprehensive sample preparation and analytical procedure was developed for determining BPA in drinking water. This fast procedure employed materials and techniques selected in part for speed, but also those that would not contribute unwanted artifacts. The use of SPE allowed BPA to be extracted plus concentrated, which may result in greater method sensitivity compared to simple headspace or ...

  • Drinking Water and Politics

    You might be interested in a recent journal paper of mine that focuses on the impact of politics on drinking water. The paper seeks to address a growing lack of historical knowledge in the water industry of how European Union (EU) water policy has developed and been responded to. It also aims to overcome the lack of comparative studies that explore the ...

  • Organisational arrangements and drinking water quality

    This paper discusses the findings of a research project which explored the impact of varying organisational arrangements on drinking water quality in England and Wales, and the Republic of Ireland. It is established that drinking water quality has been of a consistently higher standard in England and Wales in comparison with the Republic of Ireland. It is also demonstrated that the associated ...

  • Direct potable reclamation in Windhoek: a critical review of the design philosophy of new Goreangab drinking water reclamation plant

    Direct drinking water reclamation from the Goreangab reclamation plant, has been a reality in Windhoek, Namibia since 1968. Potable reclamation is a fixed part of the water supply and waste water has become an indispensible resource for the survival and continued growth of the city. The multi barrier concepts that were applied 40 years ago have been refined over many years. Improvements in water ...

  • Return of drinking water supply in Paris to public control

    The ‘reclaiming’ by Paris of its water back into public hands is a paradox in the homeland of transnational water companies and at a time when the European Commission rather favours the liberalisation of public services ‘of general economic interest’. Yet what has happened is more complex. A quick historical review of management formulas in Europe reveals both the ...

  • A policy development perspective on drinking water policy

     This paper seeks to address the lack of knowledge in the water industry of how policy development can be understood to have shaped the development and application of European Union (EU) drinking water policy. In particular, the paper develops a comparative understanding of how policy development can be viewed as having affected the development and application of the Drinking Water Directive ...

  • Chlorites Control in European Drinking Water Treatment Plants

    ABSTRACT The paper reports initial results for experiments carried out at Fortore drinking water treatment plant aimed at controlling chlorites. Research was performed in parallel with a full-scale drinking water plant (Fortore, Italy) and a pilot plant at Mosina water treatment plant which supplies potable water to the city of Poznań (Poland). Both plants operated with pre-disinfection ...

  • West Columbia, SC, municipal drinking water

    The Lake Murray Water Treatment Plant (LMWTP) in West Columbia, S.C., was dedicated in 1991 with a capacity of 6 million gal per day (mgd). With upgrades completed in 2007, the plant has a current capacity of 22.5 mgd. Most of the water from LMWTP is sold; 19% of the water is distributed to the system for which the LMWTP management and staff is responsible. 0In the early 1990s, the water ...

  • Detection of PPT levels of atrazine in drinking water

    MATRIX: Drinking Water ANALYTES: Atrazine LIMIT OF DETECTION: 5 ppt RANGE OF DETECTION: 5 to 500 ppt MATERIALS: Atrazine RaPID AssayÒ Kit and Sample Diluent Reagents: atrazine control (preparation described below), methanol and ethylacetate (pesticide grade) and distilled or deionized ...


  • Increased sample throughput for ICP-OES on drinking water and waste water

    The application of an SC-FAST sample introduction system to the analysis of natural and certified water samples is described. The SC-FAST system consists of an autosampler, sample loop, switching valve, high efficiency nebulizer and a glass cyclonic spray chamber to perform analysis by direct nebulization. The potential benefits of this introduction system are numerous and include: increased ...

  • Effects of intermittent polyelectrolyte addition on water quality in direct filtration

    The effects of intermittent polyelectrolyte addition on the quality of effluent water and on the development of filter headloss were studied. Anionic and cationic polyelectrolytes were applied to two similarly constructed pilot sand filters. The surface water used in the study was obtained from Ömerli, which is one of the main drinking water reservoirs of Istanbul. Six sets of experiments were ...

  • Direct injection ion chromatography for the control of chlorinated drinking water: simultaneous estimation of nine haloacetic acids and quantitation of bromate, chlorite and chlorate along with the major inorganic anions

    Most methods for the analysis of haloacetic acids published in recent years are based on ion chromatography with direct injection, employing a gradient elution with potassium hydroxide (KOH). This work reports the exploration of an alternative eluent, a buffer of sodium carbonate/sodium hydrogen carbonate, aimed at the simultaneous analysis of nine haloacetic acids along with bromate, chlorite ...

  • Comparing electrochemical disinfection with chlorination for inactivation of bacterial spores in drinking water

    Drinking water disinfection techniques without the dosage of chemicals are regarded as more advantageous in terms of costs and practical use. Here we investigated the efficacy of electrochemical disinfection for inactivation of Bacillus subtilis spores – a model microorganism of highly resistant pathogens. The effect of electrochemical disinfection with ...

  • The South Australian Safe Drinking Water Act: summary of the first year of operation

    The Safe Drinking Water Act 2011 was introduced in South Australia to provide clear direction to drinking water providers on how to achieve water safety. The Act requires drinking water providers to register with SA Health and develop a risk management plan (RMP) for their water supply that includes operational and verification monitoring plans and an incident notification and communication ...
