Treatment of Dairy Industrial Wastewater by Chemical Coagulation

Date of Publication :8th March 2017

Abstract: The dairy industry is among the most polluting food industries in volume to its large water consumption. More than 90% of cleaned water is converted into wastewater with demonstrating very high potential risk of environmental pollution. In the present study an attempt has been made to investigate the feasibility of chemical coagulation for the treatment of dairy wastewater by employing two coagulants like Aluminium Sulphate and Calcium Hydroxide. Analysis of pH, COD and TDS are considered as typical selective parameters for the present study. The COD removal of 76.5% and TDS removal of 73% was achieved with Aluminium Sulphate coagulant whereas COD removal of 82% and TDS removal of 79% with Calcium Hydroxide coagulant
