ABSTRACT
The physico - chemical parameters of the effluent from Haryana Distilllery, Yamuna Nagar were determined. From the various physico -chemical properties determined, Water Quality Index (WQI) values were computed to evaluate the pollution load of the effluent. According to the permissible level suggested by Bureau of Indian Standards (BIS), almost all the water quality parameters (WQPS) in the distillery effluent under study were found to be very high and above the permissible limits. It is concluded that the waste water being discharged by Haryana Distillery is highly polluted and it exceeds the prescribed limits for irrigation and public use. The percentage of sodium exceeds the desired limit for irrigation. Kelley’s ratio, magnesium ratio and sodium absorption ratio are above the limits for irrigation. Hence the distillery effluent is to be treated before discharging it in to the Western Yamuna Canal, a source of irrigation.
Key Words : Distillery effluent , Irrigation Water Quality Indices, Water Quality Parameters water Quality Index, Pollution load
INTRODUCTION
Distilleries are allied industries of sugar cane factories which produce byproducts such as molasses , baggases and fibre cakes. Among these products, molasses is most important because it is used for fermentation in distillery ,for biofertilizer industries and as feed for domestic animals. In distilleries molasses is used as raw material for the production of alcohol and besides producing alcohol, produce largest amount of
