Overview

The automatic backwash sewage filter is mainly composed of a high-quality carbon steel cylinder, a special structure stainless steel wedge filter screen, a steering valve, and a sewage device. When the filtration is normal, the water flow diversion valve is in the open state. After passing through the filter screen, the treated water uses the principle of inertia to settle small particles, impurities, and suspended solids in the water near the discharge outlet due to inertia.

Automatic backwash sewage filterStructure and Principle

Backwash sewage discharge

When backwashing and discharging, the water flow diversion valve is in the closed state, and the discharge valve is opened. At this time, the water flow is forced to enter the outer side of the filter cartridge and the shell interlayer through the inlet section of the filter cartridge, and reverse the impurities adhered to the mesh holes from the outer side of the filter cartridge, achieving the purpose of cleaning the filter. Due to the closure of the diversion valve, the water flow rate increases after backwashing, and the backwashing effect is good.
