The water to be treated comes from the inlet pipe to the two-position three-way valves. Under control of the valves, the water goes through each disc filter unit while the system is doing the filtration process.
Advantages: 1. Constant filtering efficiency: As core element of filter, the uniformity of groove style filtering superposition piece reaches to international first rate standard. 2. High efficiency backwash, energy and water saving. 3. Full automatic control, flow continuously: The filtering and backwash may be carried out at the same time. 4. Low cost, reliable and long service life system.
