How to dissolve anionic polyacrylamide

Anionic polyacrylamide is generally used for wastewater treatment flocculant, cationic polyacrylamide CPAM is generally used for sludge dewatering; anionic polyacrylamide as a flocculant when the dosage is generally 1-2ppm, that is, each treatment of 1 ton of wastewater dosage is about 1-2g; the use of anionic polyacrylamide is generally formulated as about 0.1% of the aqueous solution, cationic polyacrylamide can be formulated 0.1% -0.5%; preparation of the solution should first add water in the tank, and then open the mixer, and then anion Polyacrylamide APAM slowly added along the whirlpool. Anionic polyacrylamide agent can not be a one-time rapid input, otherwise the anionic polyacrylamide will agglomerate to form a "fish eye" and can not dissolve; after adding anionic polyacrylamide should continue to stir more than 30min to ensure its full dissolution; After the anionic polyacrylamide should be used as soon as possible, anionic polyacrylamide generally do not exceed 36h, cationic polyacrylamide dissolved easily hydrolyzed, should be used within 24 hours.
