In this paper, the response mechanism of activated sludge exposed to low-dose ozone at less than 20mgO(3)g(-1) total suspended solids (TSS) was studied by analyzing the changes in sludge activity and the evolution of C, N, P and metals from sludge following ozonation. The intracellular ATP concentration was not affected at less than 5mgO(3)g(-1) TSS and thereafter decreased rapidly to around 60% when the ozone dose increased to 20mgO(3)g(-1) TSS. Similarly, the efficiency of sludge… CONTINUE READING
