Bench-, pilot-, or full-scale studies were conducted to evaluate the cost and performance of selected treatment technologies for reducing trihalomethane concentrations in drinking water. The four Florida plant sites that were selected for study used highly organic surface or ground raw water sources and served populations of less than 30,000. Low-pressure membrane processes (ultrafiltration), polyvalent aluminum chloride (PACl) coagulation, dissolved air and froth flotation, lime softening followed by alum coagulation, and modifications to conventional lime softening and alum coagulation were investigated. Short-term pilot-scale testing of an ultrafiltration process showed great promise as a THM control technology; however, further work on process pretreatment and disposal of reject water is indicated.
