EVALUATION OF DIGESTION PARAMETERS IN AN INTEGRATE ANAEROBIC BAFFLED REACTORFOR TREATING INSTITUTIONAL WASTEWATER

Abstract

The present study was to investigate a laboratory scale integrated anaerobic baffled reactor (IABR) using institutional wastewater with eight hydraulic retention time (HRT) of 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 5.0 and 6.0 days for the degradation of organic pollutants. Six sets of an average influent Chemical Oxidation Demand (COD) of 888, 768 and 656, 1064, 1168 and 1304 mg/l were carried out for the experimental investigation. The maximum COD removal efficiency obtained was 94.37% with an OLR of 0.540 kg COD/m³.dat a HRT of 3.0 days with the addition of co substrate.
