UV FOR WASTEWater polishing
In order to protect the natural environment (rivers, lakes, beaches, coastal areas) increasingly stricter regulations have been implemented to limit release of pathogenic microorganisms originating from domestic wastewater. Therefore, many wastewater utilities have adopted ultraviolet (UV) as the most appropriate treatment option as opposed to chemical disinfection.
UV disinfection of municipal wastewater is the only cost-effective disinfection alternative that does not have the potential to create or release carcinogenic by-products into the environment. In addition, UV is an effective disinfectant for chlorine-resistant protozoa like Cryptosporidium and Giardia. While unregulated in wastewater, these harmful protozoa, if left untreated, can find their way into drinking water intakes or recreational waters.
