Hygroscopic. Performance indicators: People's Republic of China in line with national standards, "PFS water purification agent" (GB14591-93) Item Index GB14591-93 (Ⅱ) The product of total iron content,%, ≥ 19.1 reducing substances (as 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 Second, use: widely used in drinking water, industrial water, industrial waste, urban sewage, sludge dewatering of purification. Third, the application features: Compared with other inorganic flocculants have the following characteristics: 1. New, high quality, efficient inorganic polymer flocculant iron salts; 2. Coagulation excellent performance, alum dense settlement rate; 3. Net the effect of water quality, water quality, 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; 4. In addition to the cloud, discoloring, from oil, dehydrated, unless bacteria, deodorant, algae, removal of COD, BOD and heavy metal ions and significant effect; 5. adapt to a wide range of water PH value 4-11, the best PH value in the range of 6-9, after purification of raw water PH value and total alkalinity small range of processing equipment small resistance; 6. micro pollution, including algae, low temperature and turbidity water purification treatment effect is remarkable, high turbidity water purification effect is a plus; 7. low dosage, low cost, processing cost savings of 20% -50%. The use of 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. 1, before using this product at a certain concentration (10-30%) alum solution into the pool, into the fully hydrolyzed water stirred and allowed to 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 formulated 5-10% direct dosing. 2, 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 solid polymeric chloride under the same conditions roughly the same amount of aluminum, 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. 3, when used, will be prepared above the liquid pumped metering tank, dosing liquid raw water through the measurement of coagulation. 4, the date of the preparation of the day in general use, dispensing needs water, a slight sediment is normal. 5, pay attention to the water conditions of the three stages of the coagulation process and the formation of alum status. (1) The 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. (2) 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. (3) settling stage: it is in process of settling floc sedimentation tank, it 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 large number of coarse alum perianth inclined tube (plate) wall barrier deposited at the bottom, the upper water in order to clarify the water, the rest of the small particle size, density of alum was gradually decreased, while continuing to collide big knot, to the late residual turbidity 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. 6, 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. 7, the product used in environmental protection, processing, and use of industrial waste water system is substantially the same high-color, high COD, BOD of raw water treatment, combined with very good additive effect. 8, the use of 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. This product should be stored in dry, moisture, avoid hot places (<80oC, do not damage the packaging, the product can be long-term storage). 10, the product must be dissolved before use, dissolve equipment and dosing facilities should be corrosion-resistant materials.
