Four major differences between polyaluminum chloride and polyacrylamide The Chinese name of PAC is polyaluminum chloride, also known as basic aluminum chloride or aluminum hydroxychloride, which is an inorganic substance.The Chinese name of PAM is polyacrylamide, and its average molecular weight can range from thousands to tens of millions. It is an organic polymer compound.In actual use, the difference between PAC and PAM is mainly reflected in four aspects: 1. Different colors, PAC has many colors, including white, yellow, and tan.PAM is only white.2. The flocculation mechanism is different.The reason why PAC can flocculate is that it will form a network structure after entering the water, and the small solid particles will be pocketed together.PAM can flocculate because it can break the electrical balance between small particles after entering the water, so that the solid particles in the wastewater can gather together by themselves.3. Different methods of use.Before using PAC, the solid should be prepared into a solution with a concentration of 10%-20%, and then poured into the pool. It is easy to use and has no special requirements.Before using PAM, the solid should be prepared with clean water to a concentration of 0.1%-0.3
