Impact/Purpose:

Development of greener water treatment technologies is important to produce safe drinking water and also for homeland security applications such as decontamination. Clean water plays a critical role in protecting human health. The approach used by the water industry to provide safe drinking water and prevent outbreaks of waterborne diseases involves the concept of a combined filtration/disinfection treatment system. Widely used chlorine disinfectant is economical but results in generation of toxic disinfection byproducts (DBPs). Novel innovative technologies are being developed as alternative approaches for mitigation of DBPs that are formed due to the reaction of chlorine with naturally occurring organic substances in water. The combination of filtration followed by UV disinfection treatment reduces DBP formation and seems very promising for safer drinking water production. In this study, the effectiveness of a novel innovative high efficiency filtration/UV disinfection treatment system consisting of a charged membrane filter (CMF) and an ultraviolet (UV) unit was evaluated for microbial disinfection.

Description:

In both developing and industrialized nations, a growing number of contaminants are entering water supplies from human activities. In addition, the events of September 11, 2001, in the United States have raised concerns about the potential for intentional contamination of water supply systems using biological agents, as have natural disasters. These public health and environmental concerns have driven efforts to treat water sources, ensuring that the pathogens are removed and water sources are safe.
