research on a new cationic polyacrylamide (cpam) with high purity

flocculation is one of the commonly used sludge conditioning methods in water supply plants, which can improve the sludge dewatering performance by reducing the specific resistance of sludge (srf), decreasing the amount of sludge, and finally lowering the transportation cost and subsequent disposal cost of sludge. therefore, it is particularly important to develop new and efficient flocculants
