Biqing water free samples, technical support, Tracking service, your satisfaction, my pleasure ......... PFS (poly iron) Description: Name: Solid PFS (referred to solid polyethylene iron) formula: [Fe2 (OH) n (SO4) 3-n / 2] m morphological characters: pale yellow amorphous powdery solid, easily soluble in water, aqueous solutions over time into a red-brown from pale yellow transparent solution. PFS uses: PFS is widely used in drinking water, industrial water, industrial waste, urban sewage, sludge dewatering of purification. PFS application features: Compared with other inorganic flocculants have the following characteristics: the new, high quality, efficient inorganic polymer flocculant iron salts; excellent coagulation performance, alum dense settlement rate; excellent water effects, water quality Well, does not contain aluminum, chlorine and heavy metals and other harmful substances, no transfer of iron ions of the aqueous phase, non-toxic, harmless, safe and reliable; turbidity, bleaching, de-oiling, dehydration, sterilization, deodorant, algaecide , removal of COD, BOD and heavy metal ions and significant effect; adapt to a wide range of water PH value of 4-11, the optimum range of 6-9, purified small raw water PH value and total alkalinity change width, processing equipment low corrosion; micro pollution, including algae, low temperature and turbidity water purification treatment effect is remarkable, high turbidity water purification effect is a plus; low dosage, low cost, processing cost savings of 20% -50%. PFS using the methods and precautions: Due to the raw water varied in nature, should be under different circumstances, or for beaker test site commissioning, to obtain the best conditions and the best dosage to achieve the best treatment effect: Before use, the polymerization ferric sulfate according to a certain concentration (10-30%) alum solution into the pool, the water injection sufficiently stirred to hydrolysis, stand to reddish brown liquid, then diluted with water to the desired concentration dosing coagulation. 2-5% water can also be dubbed in direct dosing, industrial wastewater treatment dubbed 5- 10% direct dosing. Dosage is determined, based on the nature of the raw water may be formed by commissioning or beaker experiment, as the right amount of alum may be prepared another dose of the original water can use as a reference, the product and the amount of solid PAC under the same conditions roughly the same as a solid amount of aluminum sulfate 1 / 3-1 / 4. If the original using a liquid product, it can be calculated according to the discretion of the appropriate drug concentration. Approximate weight ratio of 1: 3 may be. In use, the liquid prepared above pumped metering tank, dosing liquid raw water coagulation by measure. Under normal circumstances the date of the preparation of the day use, dispensing needs water, a slight sediment is normal. Note that the three stages of the coagulation process and the formation of hydraulic conditions alum status. ⑴ condensed phases: a liquid into the coagulation tank and raw water coagulation in a very rapid formation of fine alum short time, then the water becomes more turbid. It requires water to produce intense turbulence. Beaker experiment should be fast (250-300 rev / min) for 10-30S, generally no more than 2min. ⑵ flocculation stage: alum is growing thicker process, requiring an appropriate degree of turbulence and sufficient residence time (10-15min), to the latter can be observed sinking slowly gathered a large number of alum, clear surface layer is formed. Beaker experiment first / min stirring for about 6 minutes at 150 rpm, and then to 60 rev / min stirring for about 4 minutes to a suspended state. ⑶ settlement stage: it is in process of settling floc sedimentation tank, requires slow water flow, in order to improve the general efficiency of the use of oblique tube (plate) settling tank (preferably separated floc flotation method), a lot of thick alum inclined tube (plate) wall barrier deposited at the bottom, the upper clarified water, the rest of the small particle size, low density alum was gradually decreased, while continuing to collide big knot, to the late residual turbidity was basically unchanged . Beaker experiment should be 20-30 rev / min slow stir 5 minutes, and then allowed to settle for 10 minutes and measured residual turbidity. Enhanced filtration, mainly rational use of the filter layer structure and aid to improve the filter's removal, it is an important measure to improve the water quality. PFS used in environmental protection, industrial waste water treatment. Use water and made much the same, high-color, high COD, BOD of raw water treatment, combined with very good additive effect. Chemical coagulation method of business, the original use of equipment without making a big transformation, just an additional pool of dissolved alum to use this product. 9, PFS must be dissolved before use, dissolved equipment and dosing facilities should be corrosion-resistant materials. Storage: PFS shall be kept in a dry, moisture, avoid hot places (<80 ℃, do not damage the packaging, the product can be long-term storage). Packing: PFS must be dissolved before use, dissolved equipment and dosing facilities should be corrosion-resistant materials. PAC (Polyaluminium Crforide) referred to PAC, also commonly known as basic aluminum chloride or coagulant, it is between AlCl3Al (OH) 3 between a water-soluble inorganic polymers, chemistry through formula [Al2 (OH) nCl6-n] m wherein m represents the degree of polymerization, n represents the degree of PAC neutral product. Color yellow, dark brown, dark gray resin-like solid. The product has a strong bridge adsorption properties, in the hydrolysis process, accompanied by physical and chemical processes occur condensation, adsorption and precipitation. PAC Performance: 1, the fundamental difference between the PAC and the traditional inorganic coagulant is the traditional inorganic coagulant for the low molecular weight crystalline salt, and the PAC by the form of changing the structure of polyhydroxy complexes composed of amorphous inorganic polymer, which exhibits many different from the traditional PAC coagulant specific coagulation functions. 2, aluminum, calcium adjust production of PAC products, basicity (basicity) can greatly improve the economic efficiency of production and use is very obvious, alkalized degree increased from 65% to 92%, raw materials costs can be 10% reduction in cost can be reduced by 40%. Water better than other similar products in the production process. PAC Uses: The product is widely used to purify the life, production water, sewage, industrial waste water, low temperature and low turbidity water purification treatment, paper, leather waste water treatment, power plant ash waste water recycling, printing and dyeing, wool, waste removal COD, BOD and SS decolorization purification. PAC use: ⑴ the solid product with water at room temperature 1: 2.5-1: 3 (weight ratio) mixture was stirred for 30 minutes, and other drugs completely dissolved, add water to dilute 30-40 times or diluted depending on the desired concentration liquid after use. ⑵ source water turbidity in the 100-500mg / L, the dosage is 5-10mg. Before using the best quality characteristics according to a small test, select the best value, and then put into use. PAC Products Special Features: ⑴ chemically stable at room temperature, long storage without deterioration, hygroscopic solid bare, but not bad, non-toxic and harmless. ⑵ adapt water PH value range 4-14, but the best treatment range of PH value of 6-8. ⑶ treated water body adaptable, quick response, less consumption of drugs, low cost of water, alum large, quick settlement, taking into account, and can improve equipment utilization. PAC Packaging and storage: The product is lined with PVC film, outer layer polypropylene woven bag, net weight 25kg /. Store in a cool, dry place to prevent the sun and rain, not with toxic, flammable, perishable goods mix.
