Evaluation of Ozonation and Chlorination for Disinfection of Blackwater.

摘要

Ozonation and chlorination were experimentally evaluated as alternative techniques for the disinfection of blackwater. The experiments focused primarily on determining the dosages of chlorine and ozone required to achieve a fecal coliform concentration of 200 colonies per 100 ml. The required ozone dosage (< 750 mg/l for the samples tested) was approximately three times as great as the required chlorine dosage (< 240 mg/l for the samples tested). Various temperatures and pH's were also investigated, but the effects of these parameters did not appear to be significant. (Author)
