ABSTRACT The present invention is concerned with a method of coagulating sludge, which comprises sequentially adding to sludge an anionic polymer coagulant having a pH of 6-8, a cationic polymer coagulant having a pH of 3-6 and an anionic polymer coagulant, each polymer being added in a coagulating amount. The method of the invention enables sludge to be coagulated at a far higher efficiency with a far smaller dewatering load than in the typical conventional methods using an inorganic salt and a pH adjusting reagent.
