The control requirement of sub- content, is added without hydrogen peroxide and is passed through air oxidation and can equally play and convert ferric ion for ferrous ion
Effect, to control production cost.
Flocculant PAM uses cationic, and iron hydroxide glue can be effectively reduced using cationic PAM in ion degree 40%
The sludge specific resistance of body, ferric hydroxide colloid particle electric double layer is by effective Fast Compression, adsorption bridging between colloidal solid, colloid
For grain unstability by filters pressing, filter cake being capable of rapid shaping.
