Advantages and disadvantages of two processes and economy 10 Ordinary fast filter and continuous sand filtration are two mature processes that are widely used at present,Difficult to distinguish,All have their own advantages and disadvantages.Economy,Easier to manage.Single,Water quality is different from standard.Sewage treatment is relatively thorough,Water quality can meet national standards.The investment is relatively large,Management is cumbersome.If it's just a general domestic sewage treatment,It is recommended to use ordinary fast filter.If there is industrial sewage,Or use continuous sand filtration.Application Scope of active sand filter I. continuous sand flow filter: Based on countercurrent principleIt is a continuous filtration equipment integrating coagulation, clarification and filtration,It is widely used in the fields of drink

What does the filter precision of stainless steel filter mean is 20U? What is the relationship between the filter mesh and the size of the mesh? The filter accuracy is 20 microns.The number of mesh of the filter is the number of holes, which is the number of holes on each square inch. The larger the number of entries, the smaller the aperture. In general, the number of mesh × aperture (micron) = 15000. So Micron number = 15000/mesh. For example, the aperture of the 400-purpose screen is about 38 microns; the aperture of the 500-purpose screen is about 30 microns. Here is the corresponding value of the number of mesh and Micron:Mesh (mesh) micron (μm)2 8000 100 1503 6700 115 1254 4750 120 1205 4000 125 1156 3350 130 1137 2800 140 1098 2360 150 1061700 160 961400 170 9014 1180 175 861000 180 80880 200 75830 230 6224 700 240 6128 600 250 5830 550 270 5332 500 300 4835 425 325 4540 380 400 3842 355 500 2545 325 600 2348 300 800 1850 270 1000 1360 250 1340 1065 230 2000 6.570 212 5000
