A Comparative Study of Sugar Mill Treated and Untreated Effluent- A Case Study

The treated and untreated effluent sample from Sir Shadi sugar mill Ltd. Shamli Distt Muzaffarnager of Western Utter Pradesh India during 2011-12 were collected and brought into laboratory for studying Physico-chemical parameters like Color, temperature, pH, DO, BOD, COD, TDS, TS, TSS, Chlorides, Sulphate and Oil & grease, heavy metals seed germination pattern of some important cereal crops. Untreated sugar mill effluent is found to have high contents of COD, BOD, TSS, TDS, and low contents of DO. Attempts were made to study the influence of sugar mill treated and untreated effluent on seed germination and seeding growth of cereal crops. The high concentration of distillery untreated effluents was found to inhibit the germination of cereal crops. According to the permissible limit suggested the Bureau of Indian Standards (BIS) the untreated effluents is toxic to plant so it is not permissible for irrigation. The results reflect that the treated effluents of sugar industry are not highly polluted and they satisfy the BIS Indian standards values and therefore can be used for irrigation purposes.
