  • Advanced Water Treatment Technologies May Bring Purified Water to San Diego

    'In four years, half of San Diego may be filling its glasses with tap water that once ran through its toilets,' reported the San Diego Union-Tribune recently. A plan to mix 'repurified water' with the City's raw drinking water reservoir could become a reality, thanks to the wonders of water treatment technology. Such a possibility elicits various reactions including disgust, marvel and fear. ...

  • Distillation treatment and removal of contaminants from drinking water

    Distillation treatment typically removes most of the dissolved materials. In addition, the boiling process kills biological contaminants. Nevertheless, there are certain volatile and semi-volatile organic compounds that may not be removed by distillation (CDPH 2009). Organic compounds that boil at temperatures greater than the boiling point of water (some pesticides) can be effectively removed ...

  • gaiasafe filter products for drinking water purification - Case Study

    Problem In some water works chlorination of drinking water is used to eliminate mikrobes. Chlorinated water may have disagreable taste and smell. Some water works use aluminium salts to clean the water. This leads to low concentrations of aluminium in drinking water. Today it is known that aluminium may be toxic to men. Old piping installations inside or outside private homes often where ...

  • Separation of finely dispersed sorbents from purified water by ultra-flocculation and turbulent micro-flotation

    This paper describes studies of the process of recovery of finely dispersed sorbents from water by means of ultra-flocculation, sedimentation and turbulent micro-flotation, and the sequential combination of these steps. With reference to the most commonly used finely dispersed sorbents in the purification of water from organic contaminants, heavy metals and radio nuclides (aluminium hydroxide, ...

  • Removal of inorganic anions from drinking water supplies by membrane bio/processes

    This paper is designed to provide an overview of the main membrane-assisted processes that can be used for the removal of toxic inorganic anions from drinking water supplies. The emphasis has been placed on integrated process solutions, including the emerging issue of membrane bioreactors. An attempt is made to compare critically recently reported results, reveal the best existing membrane ...

  • Total photosynthetic pigments in addition to turbidity during the selection of coagulant treatments: a drinking water treatment perspective

    Total photosynthetic pigments (TPP) or chlorophyll-a analysis can be useful in selecting coagulant treatments that will improve phytoplankton removal and reduce treatment costs. The objectives of this study were to compare the efficacy of phytoplankton and turbidity removal when using TPP and turbidity as indicator parameters of appropriate coagulant treatments as well as to evaluate the ...

  • Rapid, specific and quantitative polymerase chain reaction (PCR) detection of pathogenic protozoa Entamoeba histolytica for drinking water supply

    In this study, a quantitative species-specific polymerase chain reaction (PCR) method to rapidly detect E. histolytica in water is developed. First, the specificity of E. histolytica PCR detection was verified by using species-specific primers of 16S-like rRNA genes to clearly differentiate it from the closely related amoebae species E. dispar and E. ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...
