Abstract
The UASB reactor was operated at optimum Organic Loading Rate (OLR) of 0.60kg-COD/m3-day, with Hydraulic Detention Time (HDT) of 2.67-1.58hrs during the study, using actual effluent of the textile mill. The mean values of K, Ks, Kd, Y and µmax obtained while operating the UASB reactor at optimum conditions were determine to be 0.31d-1, 77.5mg/L, 0.32d-1, 0.23 and 0.26d-1, respectively. The calculated concentration of effluent substrate, HDT, effluent biomass and biomass yield were found to be 10.95mg/L, 4.8hrs, 1632mg/L and 0.28, respectively. For a textile effluent of 1000GPD, the computed volume of the reactor was found to be 12.50m3. And the determined biomass per was estimated to be 2.12kg/day. Hence, the values of coefficients K, Ks, Kd, Y and µmax obtained will be used to validate the model and to predict treatment efficiency, and predict organic loading methane productivity of any UASB reactor treating textile effluent.
