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 PriceWhat is coagulant polymeric aluminum ferric sulfate (PAFs)?
In addition, the introduction of the PO 43 − group in the PFS improved the degree of polymerization, and increased the stability of the product . In this study, the composite coagulant polymeric aluminum ferric sulfate (PAFS) was synthesized using FeSO 4 .7H 2 O and nitric acid (HNO 3) under different Al/Fe, OH/Fe and P/Fe molar ratios.
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.
Can 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.
What is polyaluminum sulfate (PAFs)?
In this investigation, polyaluminum sulfate (PAFS), an inorganic flocculant, was synthesized using municipal solid waste incineration (MSWI) fly ash. The morphology and structure of PAFS were characterized using x-ray diffraction and Fourier-transform infrared spectroscopy (FTIR).
What ions are present in a ferric coagulant?
It contains poly-nuclear complex ions, such as Fe 2 (OH) 24 +, Fe 3 (OH) 45 +, formed by the OH bridges and large number of inorganic macromolecular compounds with high positive charge, which results in efficient coagulation than the respective non-polymerized ferric coagulant .
What is an Al Fe composite coagulant?
An Al–Fe composite coagulant uses the advantage of the presence of both Al and Fe polymers, to overcome the problems associated with the individual coagulants such as generating small flocs during slow mixing speed, high residual Al concentration and the increase in residual color in treated water, etc.
