Anionic PAM Powder For Wastewater Treatment

Anionic polyacrylamide powder is widely used in wastewater treatment,mainly including the following:

Treating wastewater with more SS value, high concentration and positive-charged particles: Such as wastewater from steel plants, electroplating plants, metallurgical plants and coal washing plants, etc. Anionic PAM treatment powder can make the suspended solid particles in water coagulate to form large flocs through adsorption, bridging or charge neutralization thereby accelerating particle sedimentation and improving the effect of APAM for wastewater treatment.

Anionic polyacrylamide for water treatment, also is drinking water treatment: The water sources of many waterworks come from rivers which contain more sediment and minerals and are relatively turbid. Although precipitation and filtration are carried out, drinking grade anionic polyacrylamide for water treatment still need to be added.

Using APAM for wastewater treatment as a flocculant, the dosage is only 1/50 of inorganic flocculants, but the effect is several times or even dozens of times that of inorganic flocculants. For rivers with severe organic pollution, the combined use with water treatment powder polyacrylamide has a better effect.

APAM for wastewater treatment in starch plants and alcohol plants: Anionic PAM treatment powder can make starch particles flocculate and precipitate. The precipitate can be filtered under pressure to form cakes for use as feed, and can also be used for alcohol dehydration and recovery in alcohol plants.

The application of water treatment powder polyacrylamide in oilfield:Water treatment powder polyacrylamide can be used as a water-blocking agent for profile control and water plugging in oilfields and as an oil displacement agent for tertiary oil recovery. In terms of oil exploitation, for every ton of anionic PAM treatment powder injected, about 100-150 tons of crude oil can be extracted more.

Anionic polyacrylamide for water treatment in paper industry: Anionic polyacrylamide powder can be used as the clarifier of caustic soda solution and fiber dispersant, improve the beating degree, improve the filler retention rate and paper strengthening effect and can also be used to improve the water filtration rate and clear water recovery. Adding a trace amount of anionic polyacrylamide powder to the pump-mouth pulp storage tank before papermaking can increase the retention of fillers and fine fibers on the web by 20%-30% and save 20-30 kg of paper pulp per ton.
