Poly Ferric Sulphate PFS in water treatment

详情

Product Name: Poly Ferric Sulphate (Abbrev. PFS )
CAS No.:  ********9

EINECS No.:  ********9


Color: light yellow powder or deep red liquid

 
Molecular Formula: [Fe2(OH)n(SO4)*-n/2]m


Chacteristics:
1. It is a new, high quality and efficient inorganic polymer coagulant.
2. It has a good coagulation function with thick flocs and fast sedimentation.
3. The product has an excellent purifying effect. It is safe, reliable, nonpoisonous and harmless.

 It doesnt contain any harmful substances such as Aluminium, Chlorine and heavy metal ions,

neither does it have water phase transference of iron ions.
4. It can be used in discolouring, dehydrating, deodorizing, degreasing, sterilizing as well as

discarding heavy metal iron, radioactive substance and carcinogens in the water, and eliminate

COD, BOD, and colour.
5. It can treat water that the pH is from 4 to *1, (the optimum pH is **9).

After treatment, the pH has little change. Further, the product has little corrosiveness to the

equipment.
6. It has a very good effect in purifying the river water with algae, low temperature and low

turbidity, and slightly contaminated.

7. It has a better effect in purifying the high turbidity river water.


Specifications:

Applications:
1. Before using, dissolve the product in running water in the proportion of ****0% to have red brown solution, then dilute it to dosing solution required for coagulation.

The concentration of dosing solution is **5% for drinking water treatment,

and ***0% for waste water treatment.
2. Determination of the optimum dosage. In view of the different property of raw water,

 it can be determined by the experiment.

For the waterworks, you may refer the dosage of other flocculant operated before.

Under the same conditions, its dosage is almost equal to the Poly Aluminum Chloride,

1/**1/4 of the solid Alum.
3. It is normal to have a little of precipitation in the solution.
