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

under external pressure, these large and compact floc structures had greater compressive resistance, which avoided deformation and blockage of drainage channels and voids. it was beneficial to reduce srf and evidently enhanced sludge dewatering performance.

optimization conditions to obtain cationic polyacrylamide

for example, biosolids dewatering flocculants typically require a cationic degree of 40–50%. to dewater very young, high f/m, pure bio-sludges, cpams with a cationic degree of 60–70% would be needed. paper mill sludge dewatering flocculants would require cpams with a cationic degree of 10–30%.

optimizing the conditions of cationic polyacrylamide inverse,free radical polymerization by inverse emulsion is considered a better method to generate cpam with a high molecular weight, faster reaction rate, high conversion efficiency, and ease of controlling the temperature of the reaction [12,25].

combined use of inorganic coagulants and cationic

these results suggested that the combined use of inorganic coagulants and cationic polyacrylamide is more favorable for improving sludge dewatering performance than with individual use of coagulant or flocculant.
