THM CONTROL IN WASTEWATER EFFLUENT WITH CHLORINE DIOXIDE AS A SUPPLEMENTARY OXIDANT

Abstract

This full-scale study was designed to investigate the reduction of trihalomethane (THM) formation in wastewater effluent by augmenting chlorine disinfection with chlorine dioxide. Although the six-month trial phase has just recently been initiated, a chlorine dioxide dose of 1.4 mg/l prior to filtration and disinfection has generated encouraging preliminary results. Disinfection capabilities have remained intact with significantly less chlorine usage. Decreasing THM concentrations hasbeen linked to the decreased levels of chlorine at the specified dose of chlorine dioxide. This auxiliary chlorine dioxide system will remain in operation until approximately March 2002; therefore, more data and results will be added to the discussion as the study progresses.
