Bio-decomposition and Bio-kinetic Characterization of Tannery Effluent Treatment
N. B. Prakash, Vimala Sockan

Abstract
The paper mainly deals with the kinetic behavior of anaerobic organisms, bacterial growth kinetics, substrate utilization, kinetic models describing the biotransformation of reactions during anaerobic digestion of composite tannery effluent under varying organic loads. The studies showed that an optimum BOD influent load of. 0.8 Kg BOD/m³/day with 3 days retention time could be adopted to yield about 97 percent BOD reduction. The Biokinetic coefficients were evaluated using modified Monod’s equations to study the metabolic performance of the digestion process. The role of magnesium carbonate during anaerobic digestion has been studied for the enhancement of methane generation.
