Henan Jin-Lan Environmental Protection Technology Co., Ltd. of PAFC and good quality, excellent price, integrity first! Tel: 0371-64311988 Mobile: 15515658256, Fax: 0371-64361588 Contact: Li. Hydraulic conditions and the formation of alum coagulation process status PAFC coagulation process in three stages. 1. cohesion stage: the 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. 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 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, low density alum was gradually decreased, while continuing to collide big knot, to the late residual turbidity basic 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. 4. 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. 5. This product is 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. 6. 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. 7. This product should be stored in dry, moisture, avoid hot places (<80oC, do not damage the packaging, the product can be long-term storage). 8. This product must be dissolved before use, dissolve equipment and dosing facilities should be corrosion-resistant materials. PAFC performance: 1, high: ferric chloride-based composite polymers, the molecular structure of a large, strong adsorption capacity, water is better than all conventional inorganic purifying agent. 2, with less: for equipment, piping corrosion small, easy operation, low dosage, low cost purification. 3, fast: after floc into raw water to form a large, sedimentation speed, high activity and good filtration. Adaptable: Strong adaptability to a variety of raw water, minimal impact on the water's PH value (PH value 6-9). Regardless of the level of raw water turbidity, wastewater pollutant concentrations size, its purifying effect is remarkable.
