Polyacrylamide PAM For Waste Water Treatment
Polyacrylamide is called PAM for short,a water-soluble high polymer and widely used in water treatment,petroleum, textile,paper-making, metallurgical, and other environment protection fields. There are totally three categories of PAM: Anionic PAM,Cationic PAM and Non-ionic type.
Mechanism of Flocculation: Through adsorbing suspension particles, the polymer chains link them to form bridge which makes the flocculation structure enlarge and thicken. This will increase flocculation strength for the higher settling effectivity and faster settling rate
Usage:
Make up dilute solution based on the trial first, usually use 0.1%-0.5% to make up dilute solution. It is better to use water which is neutral and the temperature is between 50°C-60°C.
If used PAM as flocculation agent, it is necessary to select type and size of PAM series products according to treated substance.
(1) Anionic PAM is suitable for higher density, inorganic suspension substance with positive charge.
(2) Cationic PAM is suitable for suspension substance with negative charge and containing organic substance.
(3) Non-ionic PAM is suitable for separating mixed organic and inorganic suspension, the solution is neutral or acid.
