Biological and Chemical Strategies for the Treatment of Sugar Industry Effluents

Abstract

The waste effluents from sugar industries create lot of pollution problems in the adjacent areas.  Sugar industries discharge huge quantities of residual water causing damage to the biotic as well as abiotic environment due to its pungent smell, higher BOD and COD values and the exceeded concentration of chlorides, sulphates, heavy metals, carbohydrates, nutrients, oil and grease. Current studies were performed to evaluate the available strategies used to minimize the pollution load created by sugar industries. Attempts have been made to overview various available procedures such as construction of microbial fuel cell, hydrolytic pre-treatment, valorization of sugar industry waste, synthesis of silver nanoparticles, symbiotic process, chemical and electrical oxidation processes, which are used for the treatment of sugar industry effluents.
