Emulsion special agent 2 is an inorganic polymer graft copolymer with high molecular weight and unique chemical structure. After dissolving in water, it can simultaneously exert the interaction between the adsorbent and the neutralization of the particles. The emulsified oil, Colloidal coagulation and separation of precipitation; excellent degreasing, decolorization, COD removal effect. And excellent performance, the removal speed is extremely fast, can completely remove the oil glial, alum in the water large, settling speed, decolorization rate is greater than 90%, COD removal rate is very high, sludge is small.
