【Products】 PFS morphological traits are pale yellow amorphous solid powder, easily soluble in water, 10% (by weight) aqueous solution of a reddish brown transparent solution, is a new, high quality and efficient inorganic iron salts polymer flocculant. Use products PFS widely used in drinking water, industrial water, industrial wastewater, urban sewage, sludge dewatering purification. Advantages】 【PFS compared with other inorganic flocculants has the following characteristics: coagulation performance, alum dense settlement rate; purification effect of the fine, the water quality is good, does not contain aluminum, chlorine and heavy metals and other harmful substances nor iron ions in water phase transfer, non-toxic, harmless, safe and reliable; turbidity removal, bleaching, de-oiling, dehydration, sterilization, deodorization, algae, removal of COD, BOD and heavy metal ions and other significant effect ; adapt to a wide range of PH value of water is 4-11, the optimum range of PH value is 6-9, after purification of raw water PH value and total alkalinity relative amplitude of the processing equipment corrosive; pair of slightly polluted, including algae, low temperature and turbidity of raw water purification effect is significant, the high turbidity of raw water purification effect is a plus; less dosage, low cost, processing cost savings of 20% -50%. 【Specifications】 GB 14591-2006 GB 14591-2006 Ⅰ Class Project Class Ⅱ Liquid Solid Liquid Solid Density / g/cm3 (20 ℃) ??≥ 1.45 - 1.45 - total iron mass fraction /% ≥ 11.0 19.0 11.0 19.0 reducing substances (with Fe2 + meter) mass fraction /% ≤ 0.10 0.15 0.10 0.15 Basicity /% 8.0 ~ 16.0 8.0 ~ 16.0 8.0 ~ 16.0 8.0 ~ 16.0 insoluble mass fraction /% ≤ 0.3 0.5 0.3 0.5 PH (1% water solution) 2.0 ~ 3.0 2.0 ~ 3.0 2.0 ~ 3.0 2.0 ~ 3.0 Cadmium (Cd) mass fraction /% ≤ 0.0001 0.0002 - Mercury (Hg) mass fraction /% ≤ 0.00001 0.00001 - chromium [Cr (Ⅵ)] mass fraction /% ≤ 0.0005 0.0005 - arsenic (As) mass fraction /% ≤ 0.0001 0.0002 - Lead (Pb) mass fraction /% ≤ 0.0005 0.001 - [] due to the raw water use practices varied in nature, should be under different circumstances, site commissioning or for beaker test, get the best conditions of use and the optimal dosage to achieve the best treatment effect. 1, before using this product at a certain concentration (10-30%) alum dissolved into pools, into water stirring to fully hydrolyzed, standing to reddish brown liquid, and then diluted in water to the desired concentration dosing coagulation . 2-5% of water can also be dubbed in direct dosing, industrial wastewater treatment dosing directly dubbed 5-10%. 2, to determine the dosage according to the nature of the raw water through the production debugging or beaker experiment, as the formation of an appropriate amount of alum may be, under the same conditions of the product and the amount of solid PAC roughly, is a solid aluminum sulfate dosage of 1 / 3-1/4. If the original using a liquid product, according to the discretion of the appropriate drug concentration calculations. Generally at a weight ratio of 1:3 may be. 3, when used, to the preparation of a good liquid, pumped into the measuring tank, through the metering and dosing of raw water coagulation liquid. 4, under normal circumstances the date using the date of preparation, dispensing needs water, a little sediment is normal. [Note] This product should be stored in dry, moisture, avoid heat, storage and transportation of toxic substances is to prevent pollution and heat moisture, do not damage the packaging. This product is non-toxic polyethylene plastic plus woven bag, net weight: 25KG. This product can be stored for a long if there are problems, can be further consultation Shaoxing City Qingxin Water Treatment Materials Co., Order hotline Zhao Wang 18,106,881,811 13,018,805,088 13,017,705,088
