Unique place for stainless steel filter mesh installation

The unique location of the facility, the compact design of the structure, the diversified functions, the surface response, the good filtration effect, the continuous self-cleaning filtration, the effective reduction of the suspended solids content in the raw water, the selection of special raw materials, and the service life. long. The office principle of the facility and the washing: the so-called washing is the normal filtering action.

Just change the valve to the position of washing, the sewage is sent to the valve of the sand filter after the increased pressure of the booster pump, and through the continuous switching of the multi-way valve, the water passes through the sand layer and then flows from the lower water cap. It goes in, flows upward from its center rod, and finally discharges from the sewage outlet. Backwashing: Backwashing is also very simple, just change the valve to the position of backwashing.

The basic operation process is the same as the above steps. Water rushes upward from the bottom of the sand layer, so that the sand layer is constantly smashed, so that the accumulated pollutants can be washed away, and finally discharged from the sewage outlet. Operation: The principle is the same as the previous forward washing and back washing, because the switching of the multi-way valve can be completed, and the water will finally be discharged from the water outlet.

Filtration: First, turn the valve to the backwash position, and the water will be flushed from the bottom to the top of the facility through the core rod from the water inlet, and the dirty water will be discharged from the sewage outlet. After 10-15 minutes, turn the valve to the washing position, the water will be sprayed from the water inlet and flow down from the leader of the filter material, so the remaining dirty water will also be discharged from the sewage outlet. .

The whole process only takes about 10-15 minutes. At the end, the valve is turned to the running position, and the operation of the filter device should be carried out on a regular basis with positive and negative flushing. The principle is the same as the previous description.
