Polyferric Sulfate - PFS – XUNYU GROUP
Polyferric sulfate(PFS) is a polyhydroxy, combination of multi-core, cationic polymeric inorganic flocculant. It can be quickly mixed with water at any ratio. The solution contains a large amount of ferric iron and ferrous iron-like (Fe2(OH)3)3+, (Fe3(OH)6)3+, (Fe8(OH)28)4+, which has a larger molecular weight than other inorganic coagulants.

Get PriceCan polymeric aluminum ferric sulfate be used as a modified coagulation reagent?
Conclusions In this research, results of an experimental study on polymeric aluminum ferric sulfate as a modified coagulation reagents for treatment of wastewater were presented. During the process of preparing PAFS, parameters influencing the synthesis process were experimentally tested.
Which coagulant is prepared by polymeric aluminum ferric sulfate (PAFs)?
Therefore, many Al–Fe composite coagulants have been prepared such as Polymeric Aluminum Ferric Sulfate (PAFS), Polymeric Aluminum Ferric Chloride (PAFC) etc. Polymeric Ferric Sulfate (PFS) is a pre-hydrolyzed coagulant, prepared by partially neutralization of ferric sulfate.
How to use solid polyferric sulfate?
Before using,dissolve the Solid Polyferric Sulfate in running water in the proportion of 10%-30% to get red brown solution, then dilute it to dosing solution required for coagulation, the concentration of dosing solution is 2-5% for waste water treatment.
What is polymeric ferric sulfate?
Polymeric ferric sulfate is widely used in drinking water, industrial water, all kinds of industrial wastewater and urban sewage and sludge dewatering purification treatment. Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N.
