Product Description:

Polyacrylamide is divided into cationic polyacrylamide(CPAM), anionic polyacrylamide(APAM) and nonionic polyacrylamide(NPAM).  Anionic polyacrylamide (APAM) is a water-soluble polymer, mainly used for flocculation and sedimentation of various industrial wastewater, sedimentation clarification treatment, such as wastewater treatment of steel factory wastewater, electroplating factory wastewater, metallurgical wastewater, coal washing wastewater, etc. Mud dehydration, etc. It can also be used for clarification and purification of drinking water. Because its molecular chain contains a certain number of polar groups, it can absorb solid particles suspended in water to bridge between particles or agglomerate particles to form large flocs through charge neutralization, so it can accelerate particles in suspension. The sedimentation has a very obvious effect of accelerating the clarification of the solution and promoting filtration.

Application Fields:

Since the molecular chain of anionic polyacrylamide contains a certain amount of polar groups, it can absorb solid particles suspended in water, and bridge between particles to form large flocs. Therefore, it accelerates the settling of particles in the suspension, and has a very obvious effect of accelerating the clarification of the solution and promoting filtration. This product is widely used in the treatment of chemical industrial wastewater and waste liquid, and municipal sewage treatment. Tap water industry, high turbidity water purification, sedimentation, coal washing, mineral processing, metallurgy, iron and steel industry, zinc, aluminum processing industry, electronics industry and other water treatment. During use, it is sometimes used together with cationic polyacrylamide, polyaluminum chloride(industrial grade PAC or drinking water grade PAC) and PFS Polymeric Ferric Sulfate according to the situation.

1. Clarification and purification;
2. Sedimentation promotion;
3. Filtration promotion;
4. Thickening and other functions.
5. It can fully meet the requirements of various fields in terms of waste liquid treatment, sludge concentration and dehydration, mineral processing, coal washing, paper making, etc.

Packaging & Storage:

Polyacrylamide is generally packed in 15kg, 25kg, pp bags or paper-plastic composite bags, and can also be packed according to customer requirements.
The number of stacking layers shall not exceed 20, and the shelf life is 2 years. The products must be stored in a cool, shading, ventilated and dry place, and pay attention to moisture.
