Working principle of exogenous backwash system
The water to be treated comes from the inlet pipe to the two-position three-way valve on the inlet side. Under control of the valves, the water goes through each disc filter unit while the system is doing the filtration process. Water after filtering comes from inside of each filter unit to the two-position three-way valves on the outlet side. Under control of the valves, the water goes to the outlet pipe. When the filter units gather more impurities and the pressure difference reaches the setting value or the system reaches the setting time,the system will shift to backwash mode. For example, if the PLC gives a signal to two-position three-way valves on both sides of the first filter unit, the valve on the inlet side will close the inlet port and open the drain port, while the outlet side valve will close the outlet port and open the backwash port. Backwash water comes into the filter and brings the dirty to the drain port. After backwash the unit will come back to filtration mode. The system will make the filter unit do backwash one by one. When one unit is under backwash mode, others can still keep filtration state.
Working principle of filtration state:
Water to be treated comes from the inlet port into the surface of the disc cartridge. Since discs are tightly pressed by the spring on the top of the filter cartridge, with the water going into the inside of the disc cartridge, the impurity will be trapped on the intersection of discs. After that the clean water comes out from inside of the filter to the outlet port.
Backwash State:
When the pressure difference reaches the setting value or the system reaches the setting time, the system will automatically enter the backwash mode. The PLC controls the valve and changes the water flow direction. Backwash water comes from the outlet port, and closes the one-way diaphragm on the bottom of the disc cartridge. Then the backwash water can only go through from nozzle channels on the interior center of the cartridge. High pressure of the nozzle channels tightens the spring and loses discs, meanwhile the backwash water squirts out from the channel along the tangent direction of discs and rotates and separates discs evenly, taking the impurities away from the discs. After backwash state, water flow direction changes and discs are pressed again, and the filter will enter filtration state
