At present, tannery is a very important part of society, tannery industrial wastewater also has a certain pollution to the environment, and anionic polyacrylamide, just solve this problem. Leather products are closely related to our life. Such as clothes, shoes, hats, handbags, leather sofas, car cushions and so on are mostly leather products, leather products are easy to handle, long use time, but the production process of leather products is very complex.
I have been to the tannery production site before, but I still remember the pungent smell and strong chroma of the wastewater. Leather products themselves carry odor, production and processing need to add a variety of chemical additives, make odor more complex. Leather industry produced wastewater alkaline, high pollutant concentration, high chroma. Waste water contains more toxic substances and sulfide, which is one of the difficult industrial waste water to be treated. So you need to use anionic polyacrylamide to chemically treat these industrial effluents, which have been purified
Leather wastewater can be treated by physical and biological treatment to treat the water quality. In the process of water treatment, pretreatment mainly adopts coarse and fine grating to remove impurities insoluble in water or insoluble in water. Anionic polyacrylamide manufacturers recommend the use of coagulation precipitation method to remove ammonia nitrogen, suspended solids, COD, BOD and other partial pollutants. To create conditions for subsequent biochemical treatment.
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
