Abstract—In the present scenario of indian economy, sugar mills and distilleries are backbone of agro-industrial economy.At the same time these industries are facing severe effluent treatment problems.They treat effluent by conventional methods which are not adequate In the present work attempt is made to remove organic matter from the effluent by using bagasse flyash as an economical adsorbent. The studies were carried out in a batch operation to optimize the parameters like adsorbent dose, pH, initial concentration and contact time. The dissolved oxygen of the diluted effluent (1% concentration) was also reported along with COD. Experimental results for 100 ml of batch sample indicates that with an increase in adsorbent dose, COD decreases steeply up to 3 gm, and remains constant with further increase in adsorbent dose. Moreover, the dissolved oxygen of a diluted effluent (1% concentration) was found to increase from 3 mg/l to 8.5 mg/l. This analysis shows the importance of increased dissolved oxygen content for the aquatic life. The optimum pH, contact time and initial concentrations were found to be 6, 2.5 hr and 6000 mg/l respectively.
