The optimum SRT for the stabilization of WAS should be higher than 10.7 d. Effects of temperature on SCOD release were greater at SRT of 32 d and 6.4 d. CST was not correlated with soluble proteins/soluble carbohydrates in supernatant. CST was observed to be the minimum at SRT of 10.7 d both in MT-AD and RT-AD.
