  • How Does Polyaluminium Chloride Work

    2021-4-8 · The purification effect of high turbidity water is obvious. The working principle of polyaluminum chloride is mainly to destabilize the edema fine suspended particles and colloidal ions, aggregate, flocculate, coagulate, through the mechanism of adsorption electric neutralization, adsorption bridging, compression of double electric layer, and sediment net trapping, so as to achieve the purification …
