poly ferric sulfate
1. Good flocculation and water purification effect
2. Stable performance
3. Extensive usage
Poly Ferric Sulfate(PFS)
Poly ferric Sulfate/PFS
1, Molecular formula
[Fe2(OH)n(SO4)3-n/2]m
Light yellow amorphous powder solid, it is easily soluble in water, 10%(by weight) water solution is red brown apparent solution. It has the property of hygroscopicity.
2, Usage
It is widely used in water treatment of drink water, industry water, various industrial waste water, urban sewage, sludge dewatering, etc.
3,Using method and precautions
As to the different raw water properties, on site commission or beaker test can be made to different conditions, get the best use condition and the best dosage for the best handling effect.
1, Before using, put the product into dissolved alum pond as to specific density(10-30%), running water flowed stir and fully hydrolyzed, standing to a reddish brown liquid, and then diluted water to the desired concentration and put into coagulation. As to water factory, 2-5% is also can be used, 5-10% is fit for industry waste water treatment.
2, As to the dosage, it is determined by raw water properties through commission or beaker test to watching the alumen ustum, or consult the other dosage. Under the same conditions, the dosage is almost same to that of solid PAC. It is 1/3-1/4 that of solid aluminum sulfate. If it is liquid product, decided according to the pharmacy concentration calculated. Generally determined by weight ratio of 1:3.
3, During use, pump the prepared liquid into the meter tank, mix the liquid.
4, Ordinarily, it is prepared on time and running water is necessary, little sediment is normal.
