Cationic Polyacrylamide Flocculant CPAM For Wastewater Treatment

Cationic polyacrylamide (CPAM) is a linear polymer compound. Because it has a variety of active groups, it can interact with a variety of substances and adsorb to form hydrogen bonds. Mainly used for flocculating negatively charged colloids, with functions of turbidity removal, decolorization, adsorption, adhesion, etc., suitable for dyeing, papermaking, food, construction, metallurgy, mineral processing, coal powder, oil field, aquatic product processing and fermentation industries. The treatment of wastewater with high organic colloid content is especially suitable for the dehydration treatment of industrial sludge such as municipal sewage, municipal sludge, and papermaking sludge.

1) Polyacrylamide is an organic polymer compound, which can be divided into anionic polyacrylamide, cationic polyacrylamide and non-ionic polyacrylamide. It is white powder or granule, easily soluble in water, but the dissolution speed is very slow;

2) Anionic polyacrylamide is generally used as a flocculant for wastewater treatment, and cationic polyacrylamide is generally used for sludge dewatering;

3) When used as a flocculant, the dosage is generally 1-2ppm, that is, the dosage for each ton of wastewater treated is about 1-2g;

4) When in use, the anionic type is generally formulated into about 0.1% aqueous solution, and the cationic type can be formulated into 0.1%-0.5%;

5) When preparing the solution, first add water to the dissolving tank, then turn on the mixer, and then slowly add PAM along the vortex. PAM cannot be put in quickly at one time, otherwise PAM will clump to form "fish eyes" and cannot be dissolved;

6) After adding PAM, generally continue to stir for more than 30 minutes to ensure complete dissolution;
 

7) The dissolved PAM should be used as soon as possible. Generally anionic type should not exceed 36 hours. The cationic type is easily hydrolyzed after being dissolved. Should be used within 24 hours.
