Studies on biodegradation of resorcinol in sequential batch reactor

This paper reports optimization of parameters for the biodegradation of resorcinol bearing aqueous solution in a sequencing batch reactor (SBR). Various parameters studied include mixed liquor suspended solid concentration (MLSS), resorcinol initial concentration and fraction of fill phase used as aerated phase. Increases in MLSS concentration and aeration time were found to induce positive effect on resorcinol removal efficiency. The settling characteristic of sludge was measured in terms of sludge volume index. The heating value of the sludge was found to be 11.64 MJ/kg.
