Potassium Permanganate and Chlorine Reactions with Natural Organic Compounds in Algerian Surface Water

Abstract:

The aim of this work is to study effect of two powerful oxidants (potassium permanganate and chlorine) on natural organic matter in surface waters. Trials are conducted out with three Algerian surface waters under controlled experimental conditions (oxidant dose applied and contact time). Permanganate was used alone in the first step, while the combination permanganate-chlorine was used in the second step.As for chlorine demand, permanganate consumption seems correlated with physicochemical characteristics of waters and particularly the nature and content of organic matter. The effect of a coupling preoxidation by permanganate / post-chlorination resulted in a decrease of chlorine consumption and amounts of produced trihalomethanes.
