  • Release on:2020-04-17

Anionic Polyacrylamide APAM for Coal Washing Water Treatment is ultra high molecular weight polyelectrolyte copolymerized with acrylamide and acylate, molecular weight up to more than 20 million, with strong ability of adsorption and bridging, it can be used in coal washing wastewater. In coal preparation plant, generally using anionic polyacrylamide flocculant can meet the requirements,but for difficult sedimentation slime water with high ash content, fine granularity, cationic polyacrylamide is available.

Item

Anion Polyacrylamide

Advantages:

Coal washing tailing centrifugal separation
Sedimentation and filtration of coal powder and coal mud.
Highly improve the recovery rate of coal powder and the filtration speed.

Polyacrylamide Coal washing wastewater treatment option:

High molecular weight flocculant(polyacrlamide) is widely used for Coal preparation plant, it can be used in the sedimentation process to promote solid-liquid separation , High molecular flocculant contact with coal particles or slime colloid, neutralize the electrical property of slime surface, reduce surface energy, make the coal particle coagulation precipitation.
