The water filter element's value is concentrated in filtration. So how does it work? This is mainly due to the working principle behind the water filter. The liquid to be filtered passes through a high-flow filter element . Water from the inlet pipe then enters the filter through a drainage channel. It is collected by the water distribution network and discharged through an outlet pipe. After filtering for a time, the amount suspended matter in the filter layer will increase and the porosity will decrease, increasing the flow rate of pore water. The filtration resistance of the water increases on the one hand. The other side is that the water flow removes the impurities from the pores, which causes water quality to deteriorate. The filtration and reaction will take place if the head loss is greater than the allowed value or the concentration of suspended solids exceeds the limit. It is important to stop flushing the filter. The filter's backwash water enters through...
