  • Sorbents with biocidal properties for disinfection of water for various purposes

    Conventional methods for water disinfection, especially chlorination, have a lot of disadvantages and should be perfected or substituted with safer and more efficient methods. One of the possible solutions to this problem is the application of sorbents with high disinfection efficacy. In this study, the opportunity of producing sorbents with biocidal properties based on non-oxidizing biocides ...

  • Development and evaluation of a small scale water disinfection system

    Provision of microbiologically safe drinking water for people living in the rural areas of developing countries remains a major challenge to date. A simple gravity-driven membrane point of use system was developed based on woven fabric microfiltration (WFMF) membranes. The WFMF is a loose type of membrane (0.45 μm). However, complete disinfection is not achieved with the WFMF, hence it was ...

  • Chlorine Disinfection of Blended Wastewater Effluents

     KeywordsBlended Wastewater, Disinfection IntroductionFlow to publicly owned treatment works (POTWs) increases during wet weather events, due to intrusion of storm water into sanitary collection systems and use of combined sewer systems. When such flows exceed the hydraulic capacity of a POTW alternate flow management techniques must be employed to ensure that ...

  • The Benefits Of UV Disinfection In The Pharmaceutical Industry

    The quality standards required for purified water in the production of pharmaceuticals have never been stricter, with manufacturers having to conform to an ever increasing number of international standards. Craig Howarth, Managing Director of Hanovia Limited, introduces a number of interesting new developments in UV technology for disinfection and dechlorination. ...

  • Ozone as a Disinfecting Agent in The Reuse Of Wastewater

    More and more countries are taking measures to reuse wastewater. This has been prompted by the ever decreasing availability of good quality raw water and the increasing cost of producing potable water. Disinfection is a major treatment step in the direct reuse of reclaimed wastewater to ensure environmental and public health protection. “Disinfection is the destruction, inactivation or removal of ...

  • Evaluation of hybrid treatments to produce high quality reuse water

    Four tertiary hybrid treatments to produce high quality reused water, fulfilling Brazilian drinking water regulations, from a slaughterhouse's secondary treated effluent were evaluated. The pilot plant with a capacity of 500 L h−1 was set up and consisted of these stages: pre-filtration system (cartridge filter 50 micron, activated carbon filter, cartridge filter 10 micron), oxidation (H2O2) or ...

  • Disinfection By-Products (DBP) Precursor Monitoring

    Chlorine has long been used as a primary disinfection method for many water and wastewater treatment applications. However, there is growing concern about the harmful DBP’s produced by the use of chlorine. DBP’s, such as triahalomethanes (THMs), can occur when the natural organic matter (NOM) that is present in the water is combined with chlorine. More specifically, the portion of ...

  • Developmental effects and genotoxicity of 10 water disinfection by-products in zebrafish

    Disinfection by-products are contaminants produced during drinking water disinfection. Several DBPs have been implicated in a variety of toxic effects, mainly carcinogenic and genotoxic effects. Moreover, DBPs exposure has also been associated with an increased risk of developmental effects. In this study, the developmental toxicity and genotoxicity of 10 DBPs (four trihalomethanes [THMs], five ...

  • Evaluation of treatment and disinfection of water using cold atmospheric plasma

    In this paper, the disinfection of water is investigated using plasma spark treatment and the results are compared with conventional techniques. Inactivation of the Enterococcus faecalis and Escherichia coli bacteria is considered in the treatment process of water by the plasma spark. For this purpose, many physical and chemical parameters of water are measured and the ...

  • Reclaimed Water Chlorination: Reducing Chemical Cost and Improving Disinfection Efficiency

     ABSTRACT Irvine Ranch Water District’s (IRWD’s) Michelson Water Reclamation Plant (MWRP) produces 14 MGD of reclaimed water for unrestricted landscape irrigation. The reclaimed water distribution system includes two seasonal storage reservoirs that are considered waters of the State. Nitrogen removal at the plant and dechlorination prior to the reservoirs are therefore required. The ...

  • Disease-causing bacteria made more resilient by standard water disinfection practices

    Halogenated nitrogenous disinfection by-products (N-DBPs) in water increase bacterial resistance to antibiotics, new research shows. The study found that a strain of bacteria which can cause disease in humans, Pseudomonas aeruginosa, increased its resistance to a range of different antibiotics by an average of 5.5 times after the bacteria were exposed to chemicals which form as by-products of ...

  • TROJAN Wastewater Disinfection System Installed at innovative Wessex Water Works

    Wessex Water Works and Trojan Technologies Inc. have found a way to combine a new BAF (Biological Activated Filter) plant with UV technology at its sewage treatment works at Bridgewater, Somerset.
