Polymer Ferric Sulphate
Polymer Ferric Sulphate
Name: Polymer Ferric Sulphate (PFS)
Molecular formula: [Fe2(OH)n(SO4)3-n/2]m (n<2, m=f(n))
Appearance: Light yellow amorphous powder, hygroscopic, readily soluble in water. 10%(W/W) aqueous solution is a transparent orange solution.
PFS solid
PFS solution
Specification: in conformity with GB14591-93
Item | PFS solid | PFS solution |
Fe3+, % , ≥ | 19-21 | 9-14 |
Reducing substances (counted by Fe2+), % , ≤ | 0.15 | 0.1 |
Basicity, % | 9.0-14.0 | 9.0-14.0 |
PH (1% aq. solution) | 2.0-3.0 | 2.0-3.0 |
As, % , ≤ | 0.0008 | 0.0001 |
Pb , % , ≤ | 0.0015 | 0.0005 |
Non-soluble, % , ≤ | 0.5 | 0.4 |
Applications: As flocculant in purification of municipal water, industrial water, waste water, domestic sewage and sludge dewatering.
Features:
1. High-efficiency inorganic polymer flocculant.
2. Good coagulating property. Flocs formed are large and easily settable.
3. PFS is nontoxic. It can capture aluminum, chloride and heavy metal, and will not cause Fe contamination.
4. Good effect in decolorizing, capturing oil, bacteria, algae, reducing COD, BOD and heavy metal.
5. Low corrosion. Working pH range 4-11, with best performance at pH 6-9. pH and basicity of water almost do not change after treatment with PFS.
6. Suitable for purification of low-turbidity, low-algae, low-temperature, low-contaminated raw water. Particularly effective for high-turbidity raw water.
7. Lower dosage required and save 20%-50% of cost.
Usage & Caution:
Users shall determine the suitability of PFS for the raw water to be treated by sample test prior to use.
1. Preparation of PFS working solution: dissolve PFS in water at the concentration of 10-30% (W/W), stir until it is completely hydrolyzed. Dilute the result red brown liquid to required concentration, usually 2-5% for tap water and 5-10% for industrial waste water.
2. Dosage: Dosage can be determined according to the formation and settling of flocs by sample test. For treatment of tap water under identical condition, the dosage of PFS is equivalent to polyaluminum chloride, or 1/3-1/4 of that of aluminum Sulphate.
3. Pump calculated amount of the above PFS working solution into gauge tank, and add into the raw water to be treated.
4. Generally the PFS working solution shall be used right after preparation. Use pure tap water for preparation. Sometimes slight precipitation may occur depending on the water used.
5. Keep close attention to the progress of the application which may be divided into three stages:
(1Coagulation: Large amount of micro flocs formed in a very short time after the PFS working solution is mixed with raw water. The water turns more turbid. Vigorous stirring is needed at this stage, usually 250-300r/min in sample test for 10-30S¡ê?at the maximum not exceeding 2min.
(2Flocculation: The micro flocs grows to form large ones. Mild stirring at first and then standing for 1015min is required at this stage. In the sample test, stir at 150r/min for 6 min, then 60r/min for 4 min.
(3Sedimentation: water flow shall be very slow at this stage for floc settling. To achieve high efficiency, lamella settling or flotation method can be used. In the sample test, stir at 20-30r/min for 5 min, stand for 10 min, and test turbidity.
6. Compulsive filtration: choose suitable filter material or filter aid to achieve good capture effect and filtration speed. This is a key step for improvement of water quality.
