Surely everyone knows something about anionic polyacrylamide? But where can anionic polyacrylamide be used?
Anionic polyacrylamide as a common flocculant, mainly used in industrial solid-liquid separation process, especially flocculant settlement, sewage clarification, sludge concentration and other processes, the main industry applications of anionic polyacrylamide include: urban sewage treatment, paper making, petrochemical, metallurgy, food processing, dyeing and sugar and mineral processing and other industrial wastewater treatment.
Anionic polyacrylamide main application scope:
1. Domestic sewage and organic wastewater treatment. Polyacrylamide is positive in acid-base neutral medium.
2. Polyacrylamide is used as a flocculant for the treatment of tap water from rivers, with less dosage, less effect and low cost, especially the combination of inorganic flocculants is better, and it will become an efficient flocculant for the treatment of water works in the Yangtze River, Yellow River and other basins.
3. Polyacrylamide can also be used in oilfield chemical additives, such as clay anti-swelling agent and oilfield acidification thickener.
When anionic polyacrylamide is used, the concentration should be controlled at 0.1-0.2%, and the dissolution dilution tank should be set up when the supporting dissolving equipment and dosing system are not used. Use screw pump to add, dosage according to the actual situation adjustment.
With the increasing environmental protection requirements, the amount of anionic polyacrylamide will increase significantly, and the current insufficient capacity of anionic polyacrylamide in China will intensify.
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
