Physicochemical Characterization of Distillery Effluent from One of the Distilleries Found in Addis Ababa, Ethiopia

Abstract

Effluents released from distillery industries are known for the damage they cause to the natural ecosystem if proper pretreatment procedure is not performed. A study is required to assess the physicochemical property of the effluent such as colour, odour, total dissolved solid (TDS), chemical oxygen demand (COD), pH, biochemical oxygen demand (BOD), electrical conductivity, and heavy metals which are considered as the mostly reported parameters to indicate the level of pollution from industrial effluents. The present study was conducted to investigate the physicochemical characteristic of one of the distillery effluent found in Addis Ababa, Ethiopia. In our investigation lower pH, higher temperature, higher concentration of chemical oxygen demand (COD) and biochemical oxygen demand (BOD) have been recorded.
