Anionic polyacrylamide, because it has:
1, the role of clarification;
2, settlement promoter action;
3, filter effect;
4, thickener and other effects.
In wastewater treatment, sludge dewatering, dressing, washing, papermaking and so on, can fully meet the requirements of various fields.
Coal washing waste water treatment plan:
On coal slurry treatment in coal preparation plant typically use "Cyclone-filter-thickener (coal sludge sedimentation tank)" process. Under normal circumstances is buy polymer flocculants (PAM). Polymer flocculant and coal slurry coal slurry colloidal particles or contact, neutralizing the surface of coal-fired electricity, reducing the surface, particle coagulation sedimentation of slime. The molecular weight of polyacrylamide between million, coal slurry consisting of different size to use with different molecular weight flocculants. Pam can be divided into anionic polyacrylamide and cationic polyacrylamide and nonionic polyacrylamide three types. When using polyacrylamide in water treatment, make sure you type corresponds to the pH value of coal slurry, anionic polyacrylamide for alkaline slurry of cationic polyacrylamide for acidic slime, anionic and cationic polyacrylamide mixture, coal slurry flocculation effect is better.
