Polyferric Sulfate Applications in Water Treatment

Specification：

Description:

Polyferric Sulfate (PFS) is popularly favored in many sewage treatment plants as a sludge coagulant superior to the commonly used aluminum salts in settling velocity, pH scope of application, and environmental compatibility. When PFS dissolves in water, a significant quantity of highly charged polymeric cations, namely polynuclear complexes of iron with hydroxyl bridging, such as [Fe2(OH)3]3+, [Fe2(OH)2]4+, [Fe8(OH)20]4+, [Fe3(OH)4]5+, and [Fe2(OH)3]6+ are generated. Therefore, in the biochemical reaction stage of the sewage plant, the use of polyferric sulfate can change the activity of the sludge to a certain extent and enhance the dehydration of the sludge.

Characteristics

• Polyferric Sulfate production process is the most advanced technology of spray drying method.
• Poly Ferric Sulfate Solid Powder is easy to be damp when it is exposed in the air.
• Strong electric neutralization of colloidal substance in wastewater.
• The polyferric sulfate solution have the good adsorption bridging function for suspended solids in wastewater.
• Selective adsorption of soluble substances.
• Effectively remove the color matter, SS, COD, BOD and arsenic(As), mercury(Hg) and other heavy metal ions of the wastewater.

Application:

1. Drinking water purifying.
2. Sludge dewatering.
3. Industry waste water treatment (such as the paper making waste water, the printing waster water, the massacre waste water, the automobile manufacturing waste water, the beer factory waste water and so on.),
4. Many kinds of industry circulating water treatment (ex,the make-up water of the high pressure boiler in the heat and power plant, the industry waste water in biochemical treating factory, the waste emulsifying solution, the opalescent solution and the oil waste water.
5. Clarifying agent in Sugar, Medicine, Tanning, Cosmetic etc Mining water clarifying
