Abstract

 
 
 Sugarcane industry is the largest consumer of freshwater and cause of adding wastewater in environment. Wastewater generation by sugarcane industry contains high chemical oxygen demand (COD), biological oxygen demand (BOD), total dissolved solids (TDS), and Total suspended solids (TSS), it ultimately reduces accessibility to oxygen. The Sindh Environmental Protection Agency (SEPA) also promulgated legal obligation regarding effluent pollutant level through the Sindh Environmental Quality Standards (Self-Monitoring and Reporting by Industry) Rules, 2014, including priority parameters of effluent discharge for sugar industry such as Effluent Flow, Temparature, pH, BOD5, COD, Oil and Grease. If wastewater by sugarcane industry is not treated rightly, it will create very worst situation in surrounding areas including, generating foul smelling and septic condition. This toxic wastewater reduces penetration, and threat to crops and aquatic life. There are many treatment techniques such as coagulation, adsorption, membrane, biological etc. by different research studies disclosed that coagulation with different chemicals alum, ferric chloride and ferrous sulphate are very effective for remove of pollution. The adsorption technique followed by coagulation is also a very effective and time saving for sugarcane industry wastewater treatment.
