          How does the sand filter method work?

          During normal operation, the water to be filtered reaches the medium layer through the water inlet. At this time, most pollutants are trapped on the upper surface of the medium, and small dirt and other floating organic matter are trapped inside the medium layer to ensure that the production system is not affected. The interference of pollutants can work well. After the operation, when the impurities and various suspended matters in the water reach a certain amount, the filter system can detect the pressure difference between the inlet and outlet in real time through the pressure difference control device. When the pressure difference reaches the set value, the electronic control PLC will give the control system The three-way hydraulic control valve in the middle sends a signal. The three-way hydraulic control valve will automatically control its three-way valve corresponding to the filter unit through the waterway, so that it closes the inlet channel and opens the sewage channel. At this time, due to the lower pressure of the sewage channel, other filters The water of the unit will enter through the water outlet of the filter unit under the pressure of water, and continuously flush the medium layer of the filter unit to achieve the effect of cleaning the medium. The washed sewage is filtered by the water under the action of water pressure. The sewage outlet of the unit enters the sewage pipe to complete a sewage discharge process. The AIGER sand filter can also be used for timing control. When the time reaches the time set by the timing controller, the electric control box sends a cleaning signal to the three-way hydraulic control valve. The specific drainage process is as above.
