Effect of organic loading on flock formation was observed in the activated sludge process of fish-meat wastes. The presence of carbohydrates in the waste was a distinct obstacle in the purification process and, in particular, a remarkable bulking phenomenon was observed experimentaly at the concentration of 0.5% sucrose in the waste. Fish oil was also a striking obstacle in the waste purification. From the reduction rate of triphenyl tetrazolium chloride dehydrogenase activity in the bulking sludge was found to be lower than that not containing carbohydrates or oil. High nitrogen loading in the wastes caused turbidity in supernatant liquid after purification. The prolific growth of different filamentous microorganisms was found in the bulking sludge after organic loading.
