Externally rotary fed drum screen description

This stainless steel wedge wire screen is self-cleaning by nature due to constant back washing.

This often allows for only intermittent use of the spray bar cleaning system, reducing water usage.

Not well suited for fine screening of high flows, but the use of the doctor blade system makes this mechanical screen well suited when oils and grease are present.

Sized based on peak flow, solids and fats, oils, grease loadings in the wastewater/process water, these units can be configured with a variety of piping scenarios, overall dimensions and slot openings.

Bypass configurations allow for bypass of overflow when upset conditions occur.

Externally rotary fed drum screen function

The AC speed motor drives the grid cylinder through the reducer, and the sewage passes through the inlet valve to the water tank and rises to the filter water level through the uniformly distributed box plate.

The water enters the cylinder through the gap of the grid and is discharged from the bottom of the grid cylinder,and cleans the grid.

The impurities and fibrous organic substances larger than the grid gap are blocked by the grid and carried to the other side of the cylinder by the rotating grid cylinder.

After being discharged by the unloader to the slag hopper, the water content of the treated garbage is lower than 30%-50% than the original equipment.

The filtered sewage flows into the outlet tank and is discharged through the drain.
