Application of cationic polyacrylamide in the treatment of organic wastewater
Cationic polyacrylamide in the acidic or alkaline medium are positive, the sewage with negative charge of suspended particles purification treatment effect is ideal, can be fast and effective flocculation precipitation, clarify the effluent. Cationic polyacrylamide treatment of organic wastewater, mainly used in pharmaceutical wastewater, printing and dyeing wastewater, brewery wastewater, food processing wastewater, meat products factory wastewater, aquaculture wastewater, monosodium glutamine wastewater, sugar factory wastewater, textile wastewater, domestic sewage, general treatment of such wastewater with cationic polyacrylamide purification effect is better than anionic and non-ionic type effect, Because this kind of wastewater is generally more negative charge. Cationic polyacrylamide is widely used in treating organic wastewater and dewatering sludge.
Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N. It is a hard glassy solid at room temperature. The products are liquid glue, latex and white powder particles, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, aqueous solution is uniform transparent liquid. After long-term storage, the solution viscosity will decrease due to slow degradation of polymer, especially when the storage conditions are poor.  Polyacrylamide, as lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducer and thickener, has been widely used in drilling, acidification, fracturing, water plugging, cementing and secondary oil recovery, tertiary oil recovery. It is a very important oil field chemical.Learn more
Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and easily soluble in water. 10% (mass) aqueous solution is red-brown transparent solution and hygroscopic. Polyferric sulfate is widely used in drinking water, industrial water, all kinds of industrial waste water, municipal sewage, sludge dewatering purification treatment.Learn more
