Anionic Polyacrylamide Flocculant Coal Washing And Wash Sand Chemicals Agent

Anionic polyacrylamide (APAM) is a water-soluble polymer. It is mainly used for the flocculation, precipitation and clarification treatment of various industrial wastewater such as wastewater from iron and steel plants, wastewater from electroplating plants, metallurgical wastewater, and coal washing wastewater. Mud dehydration, etc., 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, bridge between particles or make particles agglomerate to form large flocs through charge neutralization, so it can accelerate the suspension The sedimentation of the particles has a very obvious effect. It has the function of accelerating the clarification of the solution and promoting the filtration.

Coal washing wastewater treatment plan:
The coal preparation plant generally adopts the "cyclone-thickener-filter press (slime sedimentation tank)" treatment process for the treatment of slime water. Under normal circumstances, it is a high-molecular flocculant (polyacrylamide) for purchased machines. The polymer flocculant interacts with the slime particles or slime colloids, neutralizes the electrical properties of the slime surface, reduces the surface energy, and makes the slime particles agglomerate and settle. The molecular weight of polyacrylamide is generally between one million, and flocculants of different molecular weights should be used for slime water of different particle sizes. Polyacrylamide can be divided into three types: anionic polyacrylamide, cationic polyacrylamide and non-ionic polyacrylamide. When using polyacrylamide for water treatment, please make sure that its type is consistent with the pH value of the slime water. Anionic polyacrylamide is suitable for alkaline slime water, cationic polyacrylamide is suitable for acidic slime water, and anionic polyacrylamide is suitable for acidic slime water. Mixed with cationic polyacrylamide, the flocculation and sedimentation effect of slime water is better.
