  • Comparative analysis of two low cost point-of-use water treatment systems

    The study examined two low-cost point-of-use water treatment systems developed in respect of bacterial and particulate removal when exposed to surface water for three months. Bacterial removal efficiency was estimated using E. coli and fecal coliforms, while particulate reduction efficiency was estimated by determining turbidity and total suspended solids (TSS). The systems investigated were ...

  • A Case for Point-of-Use RO Ultrapure Water Systems

    ULTRAPURE WATER CRITERIA - AN OVERVIEW 'Pure water' is a relative term. Practically speaking, no water, naturally occurring or treated by man, consists solely of H2O molecules. Forever in pursuit of achieving equilibrium with its surroundings, water has unique characteristics that result in its ability to dissolve most matter. This property of water to dissolve and transport materials is ...

  • A critical evaluation of two point-of-use water treatment technologies: can they provide water that meets WHO drinking water guidelines?

    Point-of-use (POU) technologies have been proposed as solutions for meeting the Millennium Development Goal (MDG) for safe water. They reduce the risk of contamination between the water source and the home, by providing treatment at the household level. This study examined two POU technologies commonly used around the world: BioSand and ceramic filters. While the health benefits in terms of ...

  • Household survey of installation and treatment efficiency of point-of-use water treatment systems in Hanoi, Vietnam

    Since urban water supply is not yet available for every inhabitant in Hanoi City, numerous residents look for alternative sources such as groundwater and rainwater to compensate the supply shortage. However, in parts of Hanoi, it was reported that groundwater is polluted by various contaminants including arsenic (As) and ammonia (NH4-N). Therefore, numerous types of point-of-use (POU) water ...

  • A compact point-of-use water purification cartridge for household use in developing countries

    Simple, low-cost household interventions are known to be effective in lowering the incidence of waterborne diseases in developing countries. However, high costs along with operational and maintenance issues have prevented the successful adoption of these interventions among the affected communities. To address these limitations, a cost-effective, gravity-driven water purification cartridge has ...

  • Application of cryptocrystalline magnesite-bentonite clay hybrid for defluoridation of underground water resources: implication for point of use treatment

    A new synthesis method was established to fabricate a nanocomposite material comprising of cryptocrystalline magnesite and bentonite clay that has high adsorption capacity for ionic pollutants. To synthesize the composite at 1:1 weight (g): weight (g) ratio, a vibratory ball mill was used. Batch adsorption experiments were carried out to determine optimum conditions for fluoride adsorption. ...

  • Point-of-use chlorination of turbid water: results from a field study in Tanzania

    Household-based chlorine disinfection is widely effective against waterborne bacteria and viruses, and may be among the most inexpensive and accessible options for household water treatment. The microbiological effectiveness of chlorine is limited, however, by turbidity. In Tanzania, there are no guidelines on water chlorination at household level, and limited data on whether dosing guidelines ...
