Correct application of stainless steel filter screen

No matter what kind of filtration equipment, it's very important to grasp the correct application method of the equipment before putting it into use Today we're going to introduce to you the correct application method of stainless steel filter screen Come and have a look with us This is a kind of filter material with different particle size used in the equipment It is arranged from bottom to top according to its size When the sewage passes through the filter layer from top to bottom, the suspended solids in the water will flow into the small pores in the upper filter material, which are subject to the double effects of adsorption and machinery, and then blocked by the surface layer of the filter material At the same time, there will be "overlapping" and "bridging" effect between these blocked suspended substances, forming a layer of film on the surface of the filter layer, which continues to play a filtering effect I features of the equipment: 1 Compact structure and diversified functions; 2 Obvious reaction and good filtration effect; 3 Continuous self-cleaning filtration; 4 Effective reduction of suspended matter content in raw water; 5 Special raw materials with long service life 2 Working principle of the equipment 1 Washing: the so-called washing is also the normal filtering action It only needs to change the valve to the washing direction After being pressurized by the booster pump, the sewage is sent to the valve of the sand filter After the continuous switching of multiple valves, the water enters from the water cap after passing through the sand layer, flows upward from the central rod, and the Zui is finally discharged from the sewage outlet 2 Backwashing: the backwashing is also very simple Just change the valve to the backwashing position The basic operation procedure is the same as the above steps The water flushes upward from the bottom of the sand layer, making the sand layer roll continuously, so that the accumulated pollutants can be washed away, and Zui is finally discharged from the sewage outlet 3 Operation: the principle is the same as the previous washing and backwashing Since the multi-channel valve can be switched, the water Zui will eventually be discharged from the water outlet 4 Filtration: first, turn the valve to the backwashing position, and the water will wash the inside of the equipment from the bottom to the top through the central pole from the water inlet, and the dirty water will be discharged from the sewage outlet After 10-15 minutes, turn the valve to the washing position, and the water will be ejected from the water inlet and flow down from the upper layer of the filter material, so that the remaining dirty water will also be discharged from the drain outlet The whole process only takes about 10-15 minutes At the end of Zui, turn the valve to the running position The operation of the filter equipment should be subject to regular positive and negative flushing The principle is the same as the previous description Through the above introduction, the correct use of stainless steel filter screen method is shown in front of everyone First, we need to know its basic performance, and then grasp the correct operation method, so that we can use this equipment well.
