Sand Filtration as an Alternative Technique for the Treatment of Distillery Effluent

Abstract

Distilleries produce large volume of wastewater which poses a considerable environmental impact by polluting water and soil bodies. The present study was conducted to find a simple and economical way for wastewater treatment. Wastewater released from distilleries was filtered by using different ratio of sand and clay soil with some amount of wood ash and charcoal. The result revealed that there was a significant reduction in parameters as: pH, COD, BOD, TDS, EC and heavy metal concentrations. Maximum percentage reduction in all parameter was obtained for the filtration with 3:1 sand and clay soil with some amount of crushed wood charcoal. Minimum reduction in all parameter was recorded for the filtration with 3:1 sand and clay soil.
