Abstract

This report compares the biocidal efficiencies of UV irradiation and chlorination using secondary effluents of varying quality; assesses the efficiency of UV inactivation of total and fecal coliforms; investigates the effect of suspended solids and particle size distribution on UV disinfection of secondary wastewater effluent; evaluates existing UV disinfection models and presents a newly developed model; and compares the economic feasibility of UV irradiation with that of chlorination/dechlorination.
