Packaging and storage PAFC product is 25kg woven bag lined with plastic film. It should be placed indoors in a cool dry place, avoid the sun and rain, not toxic, flammable, perishable goods mix. Hydraulic conditions and the formation of alum coagulation process status PAFC PAFC coagulation process in three stages of the coagulation process. PAFC picture 1. cohesion phases: a liquid into the coagulation tank and raw water coagulation in a very rapid formation of fine alum process in a short time, then the water becomes more turbid, it requires water to produce intense Turbulent. 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.
