Spray aeration is a comparatively low-cost option to reduce trihalomethane (THM) concentrations in distribution system storage. The effect of spray on unregulated, toxic disinfection by-products was investigated bench-scale apparatus closed-tank and open-tank experiments. In the experiments, initially over 90% THMs, trichloroacetonitrile, chloropicrin were removed, while 36% dihaloacetonitriles...

Photocatalysts promised to control pollution in an environmentally benign manner, inexpensively, and with a low or cheap energy input. However, the limited chemical activity of photocatalysts has prevented their widespread use. This limitation two important consequences; addition removal efficiency for pollution, may also generate unwanted byproducts due incomplete reaction. study focuses on fo...
