Explain the working principle of filtered water?

The working principle of a water filter is quite simple: when the filter is in operation, the water to be filtered enters through the inlet and flows through the filter mesh, with any particles or impurities in the water getting trapped inside the mesh. The process cycle takes place through the pipelines required by the user for export; the filter pores gradually become smaller, which creates a pressure difference between the inlet and outlet. When this pressure difference reaches a set value, the differential pressure transmitter sends an electrical signal to the controller. The controller then activates the drive motor, which uses the transmission components to rotate the shaft. Once the filter screen has been cleaned, the pressure difference drops to its minimum value, and the system returns to its initial filtering state, allowing it to operate normally.

By using water as the filtering medium, most dust and microorganisms are dissolved and trapped in the water as they pass through; the remaining particles are further filtered after passing through the filter, resulting in exhaust air emitted from the vacuum cleaner being cleaner than the air taken in.

The filtering action of the filter media is used to trap impurities in water, thereby purifying the filtered water.
