Polyferric Sulfate 【English Name】Polyferric Sulfate 【Molecular Formula】[Fe2(OH)n(SO4)3-n/2]m(n<2, m = f (n)) 【Technical Specification】 In conformity with GB14591-96 （Ⅱ） ITEM INDEX GB14591-96（Ⅱ） OUR PRODUCT IRON(FE) % , ≥ 19.0 19.0 REDUCTIVE OBJECT（CACLULATION TO Fe2+）% , ≤ 0.15 0.10 BASICITY , % 8.0-16.0 14.0 PH （1% WATER SOLUTION） 2.0-3.0 2.4 【Morphological Character】 PFS is a high-efficiency inorganic polymeric flocculant, generally non-toxic and environmental friendly. It is practically soluble in water, and forms large amount of polynucleic complex ions like [Fe2(OH)3]3+, [Fe2(OH)2]4+, [Fe8(OH)20]4+, which are prone to render flocculation. It is advantageous as regards the following points: Its cost or quantity is effectiveness, fast settling of flocs, broad pH compatibility, low iron contamination, high heavy metal removal rate, easy dehydration of sludge etc. 【Application】In purification of municipal water, industrial water and waste water in varied industries like chemical, oil, mining, paper, brewery, dye printing, steel, gas industries and more, regardless of location and type of water source. Generally, PFS is dissolved in water to make an aqueous solution prior to the addition into the water to be treated. User shall determine the dosage according to real conditions. Once added, simply stir to cause flocculation. 【Feature】with the other inorganic compared with the following characteristics : 1). New, high-quality, efficient iron salts inorganic polymer flocculants; 2). Coagulation excellent performance, alum density, velocity rapidly; 3). water purification excellent results, good quality, non-aluminum, chlorine and heavy metal ions such harmful substances nor iron to the water transfer, non-toxic, environmentally sound, safe and reliable; 4). in addition to turbidity, color, oil, dehydration, degerming, deodorant, algae removal, the removal of COD, BOD and heavy metal ions effectiveness significantly; 5). water adapt wide range of pH 4 -11, the best pH range of 6-9, purification of the raw water pH and total alkalinity of small changes in the rate of corrosion of small processing equipment; 6). right-pollution, including algae, low temperature and turbidity of raw water purification marked effect on the high turbidity of raw water purifying effect acupuncture; 7 . Dosing low, low costs, the cost savings of 20% -50%. 【Package】N. W. 25Kg, plastic woven bag with liner. 【Storage】It shall be kept well closed in a dry and ventilated place, although absorption of moisture may not influence its effectiveness. The vessel used for dissolution or delivery shall be acidproof.
