http://www.cnwatertreatment.com Our advantage: 1. Factory price, 2. Good Quality, 3. Free sample, 4. ISO Cerficate, 5. A long stable supplier, 6. Good support to you Specifications Polyferric sulfate 1. PFS have strong adsorption 2. Applicable to a wide range of PH 3. Alum the formation of large, fast, 1. Property & Specification Name: Solid Polymer Ferric Sulphate (SPFS) Molecular formula: [Fe2(OH)n(SO4)3-n/2]m Appearance: Light yellow amorphous powder, hygroscopic, readily soluble in water. 10%(W/W)aqueous solution is a transparent orange solution. 3. Features: (compared with other inorganic flocculant) 1). High-efficiency inorganic polymer flocculant. 2). Good coagulating property. Flocs formed are large and easily settable. 3). SPFS is non-toxic. 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 SPFS. 6). Suitable for purification of low-turbidity, low-algae, low-temperature, low-contaminated raw water. Particularly effective for high-turbidity raw water. 7). Low dosage required, save 20%-50% of cost. 4. Usage & Caution Users shall determine the suitability of SPFS for the raw water to be treated by sample test prior to use. 1. Preparation of SPFS working solution: Dissolve SPFS 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 SPFS is equivalent to polyaluminum chloride, or 1/3-1/4 of that of aluminum Sulphate. 3. Pump calculated amount of the above SPFS working solution into gauge tank, and add into the raw water to be treated. 4. Generally the SPFS 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: (1)Coagulation: Large amount of micro flocs formed in a very short time after the SPFS 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?
