APAM Powder For Water Treatment

Sewage APAM are many types of APAM for water treatment, among which the difference lie in the molecular weight and anionic degree of sewage APAM. 

Water treatment powder PAM ( Sewage APAM or Anionic polyacrylamide) is widely applied in industrial wastewater treatment, mainly including the following aspects:

Treating wastewater with a large number of suspended particles, high concentration and particles carrying positive charges(Sewage APAM): Such as wastewater from steel mills, electroplating plants, metallurgical plants and coal washing plants. APAM crystal powder can make the suspended solid particles in water coagulate and form large flocs through adsorption,bridging or charge neutralization, thereby accelerating particle sedimentation and improving the effect of sewage treatment by sewage APAM.

Drinking water treatment: The water sources of many waterworks in many countries come from rivers which contain more sediment and minerals and are relatively turbid. Although precipitation and filtration are carried out APAM for water treatment still need to be added.

Using sewage APAM as a flocculant, the dosage is only 1/50 of that 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 sewage APAM has a better effect.

Sewage APAM in starch plants and alcohol plants: APAM crystal powder can make starch particles flocculate and precipitate. The precipitate can be turned into cakes through pressure filtration and used as feed. APAM crystal powder can also be used for alcohol dehydration and recovery in alcohol plants.

Using APAM for water treatment in oilfield field:APAM crystal powder can be used as a water-blocking agent for profile control and water plugging in oilfields and as an oil-displacing agent for tertiary oil recovery. In terms of oil exploitation, for every ton of polymer polyacrylamide(Anionic polyacrylamide) product injected, about 100--150 tons of crude oil can be extracted more.

Anionic polyacrylamide in Paper industry: APAM crystal powder can be used as a clarifier for caustic soda solution and a fiber dispersant, improve the beating degree, increase 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 to the pump-type pulp storage tank before papermaking can increase the retention of fillers and fine fibers on the net by 20%-30% and save 20-30 kg of paper pulp per ton.
