The potential of Fe(II)-activated peroxymonosulfate (Fe(II)-PMS) oxidation under mild temperature applied to pretreat waste activated sludge (WAS) was investigated in this work. The reciprocal ratio of capillary suction time to its initial value (CST 0 /CST) was used to characterize sludge dewaterab...
