polymerization ferric sulphate (PFS)
Molecular formula: [Fe2(OH)n(SO4)3-n/2]m
Application:
used in domestic water , industrial water , industrial waste water purification treatment of urban sewage and sludge dewatering.
Polymeric ferric sulphate (PFS) is a high-efficient inorganic coagulating agent. In water treatment, it hydrolysis to many electropositive multinucleated ion which neutralized negative charge of colloidal particle in water and adsorption colloidal particle, through adhesion, bridges, cross-linking made particles flocculation and sedimentation.

Use methods and precautions :
Under different circumstances, site commissioning or for beaker test to obtain the best conditions and the best dosage to achieve the best treatment effect.
1, before using this product at a certain concentration (10-30 % ) PFS dissolved into the water stirring to fully dissolve and let stand until reddish brown liquid , and then diluted to the desired concentration watered dosing coagulation .
2 , the dosage is determined , based on the nature of the raw water can be formed by commissioning or beaker experiment , as may be the amount of alum , made raw water can be used in other dosage as a reference , the products and the solid chloride polymerization under the same conditions roughly the same amount of PFS, PFS solid dosage 1/3-1/4 . If the original product with a liquid , can be calculated according to the discretion of the appropriate agent concentration . Approximate weight ratio of 1:3 may be.
3 , when used, will be above the prepared liquid, pumped into the measuring tank , liquid dosing and coagulation of raw water through metering .
4 , the date of the preparation date of the next general use , dispensing needs water, a little sediment is normal.
5, Pay attention to the water conditions of the three stages, the coagulation process and the formation of PFS status.
Appearance
Red brown sticky and transparent liquid; Light yellow unformed solid.
