Color: morphological traits are yellowish solid amorphous powder, easily soluble in water, 10% (by weight) aqueous solution of red-brown transparent solution, hygroscopic. PFS is widely used in drinking water, industrial water, industrial wastewater, urban sewage, sludge dewatering purification. MF: [Fe2 (OH) n (SO43-n / 2] m morphological characters: pale yellow amorphous solid powder, easily soluble in water, 10% (by weight) aqueous solution of hygroscopic properties of red-brown transparent solution indicators: the national standard "PFS" (GB14591-93) Item Index GB14591-93 (Ⅱ) The product total iron content,%, ≥ 18.5 19.1 reducing substances (to Fe2 +) content%, ≤ 0.15 0.01 Basicity,% 9.0-14.0 14.0 PH (1% solution) 2.0-3.0 2.4 arsenic (As) content,%, ≤ 0.0008 0.0001 Lead (Pb) content,%, ≤ 0.0015 0.0001 insoluble content,%, ≤ 0.5 0.4 Application Features: Compared with other inorganic flocculants has the following characteristics: a new, high quality, efficient inorganic polymer flocculant iron salts; 2 excellent coagulation performance, alum dense settlement rate; 3 water.. effect of the fine, good water quality, does not contain aluminum, chlorine and heavy metals and other harmful substances, nor the transfer of iron ions in the aqueous phase, non-toxic, harmless, safe and reliable; 4 turbidity, bleaching, de-oiling, dehydration, sterilization , deodorant, algae, removal of COD, BOD and heavy metal ions and significant effect; 5 PH value of water bodies to adapt to a wide range of 4-11, the best PH value range is 6-9, PH value of the raw water after purification and Small changes in the magnitude of the total alkalinity, processing equipment, small corrosive; 6 for slightly polluted, including algae, low temperature and turbidity of raw water purification effect is significant, high turbidity raw water purification effect is a plus; 7 less dosage, cost Low treatment cost savings of 20% -50% PFS Uses: Widely used in drinking water, industrial water, industrial wastewater, urban sewage, sludge dewatering purification purchases PFS need help, please. call 0371 -60,263,358 Tel: 18337183918 Zhengzhou Tianhe water purification materials Limited committed to provide you the best quality products and the most sincere service welcome new and old customers to inquire, we have technical experts 24 hours to provide you with technical services.
