  • Water reuse market is all set for dramatic expansion

    "Water reuse market is all set for dramatic expansion" - a review by Sahana Singh, Editor, Asian Water, February 2010 From a probable solution to a low-value proposition and finally to the current avatar of high-value application, water reuse is all set to revolutionise the urban world. Driven by water scarcity, revulsion for big dam projects and a progressive breakdown of the ‘yuck ...

  • Efficiencies of advanced formulation Manganese - Case Study

    With manganese being the most commonly deficient trace element in UK soils and potentially impacting on the development, health, quality and yield of arable and vegetable crops, countering deficiencies is a necessity for many farms. John Bird from F D Bird & Sons, tells us how switching to a lower volume product has brought efficiencies in both time and cost.  Treatment of manganese ...

  • Neuthox improves the water quality by removing unwanted bacteria - Case Study

    NEUTHOX removes biofilm in cooling tower and leaves the water system completely free of unwanted bacteria Using an electrolysis process of saltwater the ECA generator produces the liquid NEUTHOX, which contains hypochlorous acid, and is highly efficient in eliminating bacteria. A biofilm consists of living and dead organic and inorganic material collected on a surface, which in ...

  • Data analytics methodology for monitoring quality sensors and events in the Barcelona drinking water network

    Water quality management is a key area to guarantee drinking water safety to users. This task is based on disinfection techniques, such as chlorination, applied to the drinking water network to prevent the growth of microorganisms present in the water. The continuous monitoring of water quality parameters is fundamental to assess the sanitary conditions of the drinking water and to detect ...

  • Water quality characteristics of Poyang Lake, China, in response to changes in the water level

    As one of the few remaining lakes that are freely connected with the Yangtze River, Poyang Lake exhibits large annual water level (WL) fluctuations. In this study, weekly samples were collected at the north end of Poyang Lake from September 2011 to December 2012, and we investigated the mechanism of limnological responses to fluctuations in the WL. The study covers three seasons that were ...

  • An integrated model for simulating and diagnosing the water quality based on the system dynamics and Bayesian network

    An integrated model for simulating and diagnosing water quality based on the system dynamics and Bayesian network (BN) is presented in the paper. The research aims to connect water monitoring downstream with outlet management upstream in order to present an efficiency outlet management strategy. The integrated model was built from two components: the system dynamics were used to simulate the ...
