    The principle of action of polyacrylamide flocculants

    PAM molecular chains can be fixed on different particle surfaces to form a bridge between the sludge colloidal particles and the polymer, and at the same time, the polar groups on the molecular chains adsorb the dispersed particles, so that the particles form large Agglomerates of blocks settle.【detailed】

    Brief introduction of polyacrylamide

    Polyacrylamide (PAM) is a water-soluble polymer, insoluble in most organic solvents except polar solvents such as acetic acid and chloroacetic acid, and has good flocculation performance, which can reduce the frictional resistance between liquids. According to their ionic properties, PAM can be divided into four types: cationic, anionic, amphoteric and nonionic.【detailed】

  • How to select the appropriate PAM type for wastewater treatment plant (Part 2)

    How to select the appropriate PAM type for wastewater treatment plant (Part 2)

    Polyacrylamide PAM has good water retention and drought resistance to the soil. The test results show that the time to reach the wilting point of barley and lettuce increases with the increase of the concentration of polyacrylamide PAM, and even at a lower concentration, the time to reach the wilting point is 5 times longer than that of sandy soil without PAM. 【detailed】
