Abstract:
A vacuum ultraviolet coupled with multistage filtration system with a treatment capacity of 1.5 m3/d was employed to treat the effluent from the end of a municipal water supply network. The performances of the system for the removal of organic micropollutants (atrazine), assimilable organic carbon (AOC), microorganisms, residual chlorine, disinfection byproducts (trichloromethane) and dissolved organic matter were continuously monitored. The system removed all atrazine in water during the operation. The effluent AOC was always less than 70 μg/L, and the total number of microbial colonies was below 10 CFU/mL. In addition, the system also had a good removal efficiency on dissolved organic matter in drinking water. The system effectively improved the water quality of the water supply network and ensured the health and safety of drinking water for the people.
