Is the mixing effect of PAM and polyaluminum chloride good?

PAM is a polymer water-soluble polymer, which is a high-efficiency flocculant for wastewater treatment. It can be divided into anionic PAM, cationic PAM and non-ionic PAM, and zwitterionic PAM according to ionic type.

Polyaluminum chloride is an inorganic polymer coagulant, abbreviated as polyaluminum PAC, which is produced by the bridging action of hydroxide ions and the polymerization of polyvalent anions. Pharmacy. In terms of morphology, it can be divided into solid and liquid. The solids are divided into brown, beige, golden yellow and white according to different colors. The different colors of polyaluminum chloride also have great differences in application and production technology.

Polyaluminium chloride itself is also a water purifying agent. In some industries with low requirements and a single water quality component, the treatment effect can also meet the emission requirements. PAM has a very good effect in treating wastewater. It can achieve very good results when used alone, but it is not omnipotent. In many cases, it works better with inorganic coagulants. PAM must pay attention to the following when used with polyaluminum chloride:

1) PAM and polyaluminum chloride cannot be dissolved in one dissolution tank.

2) Determine the PAM model used in combination with polyaluminum chloride by experiment.

3) It is determined through trial and error that the delivery of PAM and polyaluminum chloride is sequential.

4) Determine the amount of PAM and polyaluminum chloride by experiment.

5) Control the reaction time of wastewater and two agents.
