Action principle:
(1) Charge Neutralization: PFS has a strong charge neutralization effect on colloidal substances in water.
(2) Viaduct Adsorption: the hydrolysis of PFS has an excellent adsorption effect on suspended solids in water.
(3) Selective Adsorption: PFS has selective adsorption effect on dissolved substances.


1. purifying and clarifying Sewage, Industry and textile wastewater.
2. Wastewater phosphorus treatment.
3. Sludge thickening
4. Heavy metals removal
5. Struvite control and Ordor control
6. Used as inhibitor and oxigen in mine , solvent extraction.
7. Industry waste water treatment (such as the paper making waste water, the printing wastewater, the massacre waste water, the automobile manufacturing waste water, the beer factory waste water and so on).
8. 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.  


How to use:

Dissolve the solid first, make it into 10% aqueous solution, then put the solution into wastewater or sludge.

PFS Advantages:
1. the effect of PFS is obviously better than aluminum sulfate, When the dosage is above 200*10-5.
2. In purifying, precipitating, dehydrating, deodorizing and other aspects, PFS works better.
3. Wide PH range (4~11) and wide water temperature range have no effect on PFS. Little causticity to the equipment.
4. Larger alum, and faster formation.
5. It will have less iron ion after purifying with PFS. and PFS is innoxious.
6. For COD, BOD, color and heavy metals in all kinds of wastewater, PFS has a better removal effect.
7. The flocculi (flocculating) body has a strong ability to combine with microorganism, so it has a good removal effect on plankton and other microorganisms.
8. Reducing the content of nitrate nitrogen and iron in water.
