If you want to clean up the sewage in the sand washing site, the effect of compaction is better. First of all, the flocculation speed should be fast, and then the water quality should be clear. The effect of mud clumping is better. Generally, we recommend using anionic 12 million molecular weight and nonionic.

Anionic polyacrylamide is usually used as a sand washing flocculant for the wastewater treatment of sand washing sites. Anionic polyacrylamide is a water-soluble polymer. Because its molecular chain contains a certain number of polar groups, it can adsorb solid particles suspended in water, bridge the particles or neutralize the charge to agglutinate the particles to form a large flocculant.

Choose the right polyacrylamide model, the sludge impurities can be pressed into a mud cake through a filter press, and the dissolved agent is fully mixed with the sewage through the premix tank. The sewage flows into the first sedimentation tank to achieve mud-water separation, the mud clumps tightly and is easy to clean up, and the fresh water flows into the second sedimentation tank. Excessive, and finally flows into the clear water tank to realize recycling.
