Abstract
A comparative study of air and pure oxygen activated sludge systems, with respect to energy requirements and performance characteristics, was conducted. It was shown that despite the higher efficiency of absorption the oxygen system is in most practical cases more energy demanding than the air system. Treatment efficiencies and sludge production rates were found to be similar in both cases. However, the oxygen system produced a sludge with better settling characteristics, particularly when operated at low BOD loadings.This publication has 5 references indexed in Scilit:
