4. How sand filter works

1. Filtering

When filter is under operation, the original water flow into packing layer advective by through
The upper water distributor, in where matched with spherical shell. Impurities are hold back at
Packing layer. Then Collector under filter will accept these water, and flows out them. One thing
Needs to emphasizes that advective filtering can improve the filter efficiency under the high speed

2. Backwash

The head loss increases as the impurities accumulates at packing layer continuously. When
It comes into a limit or reached to time limit, system will switched into backwashing to clean
Packing layer's impurities. To clean these accumulated impurities is a must thing.
In the process of backwash, the on-off switch of three-way valve will be changed by PLC,
With inlet closed, and drain let open. Impurities will out through three-way vale's drain outlet.
On FQG system, a circulation exists at packing layer under the function of the specialized
Collector. Silica sand rub each other, which high efficiently improves the backwash. When
Backwash is finished, valve returns to filtering state, which another filtering comes into backwash.
Normally a filter system is made of multi-filter tank, they work in turn, which ensure there's no
Stop in backwash.
