Stainless Steel Filter Disc For Sewage Filtration

The stainless steel filter disc is a mesh made of stainless steel wire after bending and then weaving. This mesh has strong rigidity, and the mesh is square and the hole is large.

Features of stainless steel wire cloth discs:

Direct filtration, simple process, good air permeability, uniform and stable precision, no leakage, good regeneration performance, fast regeneration speed, convenient installation, high efficiency and long service life.

Stainless steel filter disc for sewage filtration:

The medium enters from the inlet of the filter device, and then passes through the sewage filter screen from the inside to the outside. The impurities larger than the mesh are intercepted and accumulated on the inner surface of the filter screen to form a filter cake. These filter cakes can also capture some of the finer particles in the water of impurities.

Self-cleaning process:

The differential pressure switch continuously detects the differential pressure inside and outside the filter screen, and when it reaches the preset value, it will transmit a signal to the control box to start the cleaning cycle. The cleaning mechanism of the filter device is a sewage suction device that moves up and down in a spiral type. It is a hollow structure, and several sewage suction pipes are evenly distributed vertically and evenly at a certain distance on its axis.

The dirt extractor communicates with a blowdown valve. When the blowdown valve is opened, the pressure difference formed between the water pressure inside the filter device and the outside atmosphere makes the suction pipe generate strong suction, and the water flows from the outside of the filter screen to the inside in reverse at high speed to flush the impurities down into the sewage suction device and discharge through the blowdown valve.
