Abstract
Upflow anaerobic sludge blanket reactor (UASBR) works best in the hot climatic condition. In India, UASB process has been used in almost 23 sewage treatment plants. However, when UASB process is applied for sewage treatment (where the undiluted BOD is between 200–300 mg/L), the cumulative experience has shown need for post-treatment of UASB effluent. During last two decades, more efforts have been put on use of electrocoagulation (EC) process for treatment of various effluents. Literature has reported promising results also. Study undertaken focuses to evaluate applicability of EC process for post-treatment of UASB reactor-treated municipal wastewater. Understanding the significance of various process variables is initial step to be achieved before optimizing any process. EC has many process variables like current density (CD), electrolysis time, influent waste strength, initial pH, electrolyte dose (NaCl dose), interelectrode distance etc. Here, significance of CD, time and NaCl dose were studied. Response surface methodology (RSM) was used as statistical tool for experimental design and data analysis with Design Expert software version 8.0. It is understood from the results that CD and time are significant variables, while NaCl dose was not found significant variable. Thus, it is reported from the study that process efficiency of electrocoagulation of sewage pretreated with UASBR will be affected with change in current density and electrolysis time but electrolyte variation found insignificant.
