For different types of raw mud such as municipal sludge, river and lake sludge, ditch sludge, construction mud, etc., deep dewatering of sludge/bottom mud (municipal sludge Wc<60%, dredged sludge Wc<30%) is achieved by fitting efficient and neutral conditioning agents and combining precise dosing control methods. The relevant agents and their application schemes have been successively applied in Changsha sludge comprehensive disposal and Wuxi Taihu dredging projects, and have obtained positive evaluation.
