BIOCHEMICAL OXIDATION KINETICS OF WASTEWATERS FROM A NATURAL RUBBER PROCESSING INDUSTRYG. Madhu, K. E. George and D.Joseph Francis
The composite effluent samples obtained from a centrifuge rubber latex concentration unit in South India were analysed for their biochemical oxygen demand (BOD) values at 200C for definite periods in days. From the values obtained, oxygen utilisation and biochemical stabilisation rate constants, K and k respectively were determined. The average values obtained for K and k were 0.333 day' and 0.145 day-) respectively. The ultimate BUD (Lo)value for rubber latex concentration effluent was found to be 5475 mg/I.
