Abstract
The investigation covered studies on the accumulation of volatile solids in extended sludge aeration activated sludge systems grown on sodium acetate, the rates of synthesis and degradation of proteins, carbohydrates, and fats in extended sludge aeration activated sludge. It was found that for extended sludge aeration (long sludge retention time) activated sludge operating either as a conventional activated sludge plant or as a uniform concentration activated sludge plant, volatile solids continually accumulated in the system.
