Distillery Wastewater Management using Natural Coagulant for Sustainable Environment

In India distilleries have become a major source of pollution as 88% of its raw materials are converted into waste and discharged into the water bodies, causing water pollution. The present study determine physical and chemical parameters in the treatment process of distillery wastewater using natural coagulants and assessing by comparing the performance with chemical coagulant alum. The plant-based method was best for distillery wastewater treatment. The crude extracts obtained from natural coagulant Hibiscus rosa-sinensis followed by Moringa oleifera have manifested improved coagulation performance compared to commercial alum. It exhibited a good reduction in turbidity, sulphate, biological oxygen demand, and chemical oxygen demand.
