Polyacrylamide for Sludge Dehydration Treatment

Polyacrylamide is used for sludge dewatering. Polyacrylamide is a commonly used product for sludge dehydration. Different industries require different product models and technologies. The molecular weight of polyacrylamide affects the size and stability of the flocculation. If the flocculation is too small, it will affect the speed of drainage. If the flocculation is too large, the flocculation will bind more water and reduce the degree of mud biscuit.

Before choosing polyacrylamide, we must first understand the source, characteristics and composition of sludge. According to the different properties of sludge, it can be divided into organic and inorganic sludge. Cationic polyacrylamide and anionic polyacrylamide are respectively suitable. When the alkalinity is strong, cationic polyacrylamide can be used, but when the acidity is strong, anionic polyacrylamide is not suitable. When the solid content of the sludge is high, the amount of polyacrylamide is usually large.
