Spray dried PFS ( polymeric Ferric Sulphate ) used in water treatment
polymeric ferric sulphate PFS,for water treatment
A, Product specifications: Polymeric ferric sulfate morphological character: light yellow amorphous solid, it is easy to dissolve in the water, 10% (weight) of aqueous solution for red brown transparent solution. Moisture absorption. Flocculant polymerization ferric sulfate are widely used in drinking water, industrial water, all kinds of industrial waste water, city sewage and sludge dewatering of purification treatment. B.Performance: Conform to the national standard of the People's Republic of China "the sparsity of polymeric ferric sulfate" (GB14591-93)
GB14591-93 (II) | Typical measured values | |
Fe, % , ≥ | 18.5 | 19.1 |
Reducing substances (counted by Fe2+), % , ≤ | 0.15 | 0.01 |
Basicity, % | 9.0-14.0 | 14.0 |
PH (1% aq. solution) | 2.0-3.0 | 2.4 |
As, % , ≤ | 0.0008 | 0.0001 |
Pb , % , ≤ | 0.0015 | 0.0001 |
Non-soluble, % , ≤ | 0.5 | 0.4 |
C.Application features:
1. The economy, high quality, and high efficiency lron kind of inorganic polymer flocculant, 2. Polymeric ferric sulfate coagulation excellent performance, alum flowers dense, sedimentation speed;
(3) flocculant polymerization ferric sulfate purification effect is good, good water quality, do not contain the aluminum, chlorine and heavy metal ions and other harmful substances, and also have no iron ion water phase transfer, non-toxic, harmless, safe and reliable
4. Turbidity removal, decoloring, to take off the oil, dehydration, degerming, deodorization and algae, remove the water COD, BOD and heavy metal ions, such as effectiveness significantly;
5. Polymer iron sulfate water PH value to adapt to a wide range for 4-11, optimum PH value range is 6-9, after purification of raw water PH value and total alkalinity variation amplitude of small, to processing equipment corrosive small;
6. To the micro pollution, containing algae, low temperature and low turbidity raw water purification treatment effect is remarkable, the high turbidity water purification effect is a plus;
7. Polymeric ferric sulfate drug dosage less, the cost is low and the processing costs can save 20% - 50%.
D. Method of use:
Because of the different nature of raw water, should according to the different conditions, the commissioning or beaker test, obtains the best conditions of use and the best drug dosage in order to achieve the best treatment effect .
1, before using, will polymer iron sulfate in a certain concentration (10-30%) into soluble alum pool, injection water mixing make full hydrolysis, quiet place to a reddish brown liquid, again against the water dilution to required concentration coagulation dosing. Water can also match into 2-5% direct additive, industrial wastewater treatment with directly into 5-10% additive.2, the determination of dosing amount, according to the nature of raw water by production debugging or beaker experiment apparent alum flowers form right amount and decide, system water can original with other medicine dose as reference, under the same conditions polymerization ferric sulfate and solid polyaluminium chloride dosage is approximately equal is solid aluminium sulfate dosage of a third - 1/4. If the original use is liquid product, can according to the corresponding agent concentration calculation for discretion. General weight than 1:3 and decide.3, when using, the above preparation good liquid medicine, pump into the tank, through measuring additive solution and raw water coagulation.4, usually the preparation day use, dispensing need water, slightly sediment is a normal phenomenon.
E.The main items:
7, polymeric ferric sulfate used in environmental protection, industrial wastewater treatment, use method and system waterworks is approximately the same as that of high chromaticity, high COD, BOD of raw water treatment, complementary with auxiliary role in good effect.
8, the chemical coagulation method of the enterprise, the original use equipment need not make big transformation, just add soluble alum pool can use polymeric ferric sulfate.
9, polymeric ferric sulfate should be stored in dry, moistureproof, avoid hot place (< 80 oc, do not damage the packaging, the product can be stored for a long time).
10 and polymeric ferric sulfate must be dissolved to use, dissolving equipment and dosing facilities should adopt resistant material.
F. Package Plastic woven bag with PE liner. n.w. 25kg.
