APAM-Anionic Polyacrylamide, Water Treatment Chemical

It is the white powder. The APAM with the molecular weight of4,000,000-26,000,000 has good water solubility, and it can bedissolved in water by arbitrary proportion but not in organicsolvents. It has the characteristics of high-polymer electrolyte inthe neutral and alkaline medium, and it is sensitive to theelectrolyte salt. And it can be cross-linked into insoluble gelwith the high valence metal ions.

Use:

(1) Industrial waste water treatment:

For the neutral or alkaline waste water with pH value of 7-14,large suspended particles and ions of positive charge, it has thebest treating effect, such as the waste water from iron industry,electroplating factory, metallurgical industry, coal washing,etc..

(2) Drinking water treatment:

When the drinking water still does not meet the standard afterthe treatment of the precipitation and filtering, then the APAM canbe used as the flocculant. Its dosage is 2%-5% of that of theinorganic flocculants, but the effect of former is dozens of timesof that of latter.

(3) It can be used for the recycling of the loss of brewers''grains in the alcohol plant and starch in the starch factory.

(4) It can be used as the water block agent in the oil field,and also the oil-displacing agent during the tertiary recovery.

(5) It can be applied in the paper-making industry. It can beused as the dispersant, retention aid, etc. in the long fiberpaper-making, and also the flocculant for the waste water from thepaper-making
