GT-D02 is a kind of highly efficient cationic flocculant, which is a patent product of our company independently developed. The product is a composite polymer water treatment chemicals, with a large number of positive charge groups on the molecular chain, is a kind of unique properties of the cationic polymer. With a strong flocculation and demulsification capability, used in the treatment of wastewater of machining wastewater, waste cutting liquid and high oil, high COD sewage, high chroma sewage treatment and sludge concentration. This product can be used as a high efficient cationic flocculant, but also as a reverse phase of oily wastewater, oil and water separation agent, bleaching agent and flotation agent. This product is used in conjunction with GT-D01, and has a good effect on treating high concentration emulsion wastewater.
