Effectiveness of Water Treatment Processes in Pesticide Removal

Abstract

This article discusses the effectiveness of water treatment processes in coping with relatively small concentrations of pesticides in raw water. Duplicate pilot water treatment plants at the Taft Center were used to evaluate the effectiveness of conventional and auxiliary treatment processes. The methods and procedures used included: the chromatographic method; solubility and incidental loss; coagulation and filtration; chlorine; potassium permanganate; ozone; powdered activated carbon; and, granular activated carbon.
