Zhenqing Water clearing agent is an organic-inorganic macromolecule synthetic polymer that can quickly and effectively destroy the electric double layer at the oil-water interface, reduce the strength of the interfacial film, and significantly reduce the interaction with the anionic polymer in the sewage, and has excellent water-clearing effect. At the same time, the reaction speed is very fast, the resulting compact silk flower has good fluidity, and the separation speed is fast, which can effectively avoid the sticky "containing sludge" problem in sewage treatment.
