The kinetics of photochemical oxidation of organic carbon pollutants, with and without sensitization by chlorine, have been determined. The results, which are suitable for use in designing reactors for any type of lamp and lamp-reactor geometry, are based upon data obtained for secondary effluents from Sacramento area municipal treatment plants. A trough reactor with parabolic reflector was the most suitable design for a large-scale, tertiary treatment plant based upon photochemical oxidation. Cost calculations were made for reducing the TOC from 10 to 4 mg/liter and maintaining a chlorine concentration of about 0.8 mg/liter. For a capacity of one-million gallons per day of secondary effluent, treatment costs are given. (Author)
