High purity polyacrylamide manufacturers recommend polyaluminum chloride, complex alkali, ferrous sulfate, polyacrylamide and other suitable for leather wastewater treatment of drugs, so that the water quality to meet the discharge standards. Due to the addition of raw materials, leather wastewater will produce a variety of organic compounds. We know that organic matter is difficult to remove through biochemical treatment. Ozone method and gao grade oxidation method are commonly used in leather wastewater treatment. Therefore, the application of acid and base in leather industry accounts for a large proportion. After a series of process treatment, water quality back end again coagulation precipitation is the key.
When it comes to coagulation sedimentation, the selection of polyacrylamide directly affects the effluent quality when flocculating leather wastewater. Anionic polyacrylamide is used for leather wastewater flocculation. The molecular weight and addition amount of polyacrylamide used for different leather are different. The chemical reagents used for pretreatment and back-end treatment are also different. In the selection of polyacrylamide, can be determined by a small test method to determine the content of the product and dosage into the sewage tank to add, determine the selection of high purity polyacrylamide suitable for the treatment of this industry wastewater.
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
