Abstract

Distillery wastewater and its toxicity is a serious concern worldwide. Unfortunately, if discharged into the environment without proper treatment, it causes serious environmental problems and health hazards in human and animals. Due to very high chemical oxygen demand (COD), biological oxygen demand (BOD), it causes inhibition of seed germination and depletion of vegetation by reducing the soil alkalinity and manganese availability in agricultural land whereas in aquatic environments, it reduces sunlight penetration and decreases photosynthetic activity and dissolved oxygen content damaging the aquatic fauna and flora both. Various physico-chemical and biological approaches employing membranes, coagulant, bacteria, fungi, microalgae etc. used for the treatment of distillery wastewater.
