Anionic polyacrylamide is a kind of polymer material with good water solubility and adsorption properties, so it has been widely used in water treatment. Its main function is to act as a flocculant by attracting charged parts of suspended particles in water to aggregate them into larger clumps for easy precipitation or filtration.
The advantages of anionic polyacrylamide in water treatment include the effective removal of suspended matter, turbidity, organic matter and other pollutants, while the pH value of the water is less impact, will not destroy the chemical balance of water, so it is widely used in water treatment, sewage treatment and industrial wastewater treatment fields.
However, anionic polyacrylamide in the process of use there are also some problems, such as may affect the growth of microorganisms in the water, human health is also a certain risk, therefore, in the use of anionic polyacrylamide need to pay attention to its dosage, use mode and use range, and need to strictly control the amount of residual water. Avoid adverse effects on the environment and human health.
In addition to acting as a flocculant, anionic polyacrylamide can also be used as an adsorbent to remove contaminants from water by interacting with dissolved ions or organic matter in water and fixing them to the surface of polymer materials. In addition, anionic polyacrylamide can also be used to prepare hydrogels, waterproof agents and other materials, which has a wide range of application prospects.
In conclusion, the application of anionic polyacrylamide in water treatment has wide prospect and important significance, which can effectively remove pollutants in water. But at the same time, it is necessary to pay attention to the restrictions and precautions of its use to avoid adverse effects on the environment and human health.
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
