Modular & Skid-Mounted External Rotary Fed Drum Screen | Pre-Assembled for Easy Installation

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 equipment is composed of rotating drum, driving mechanism, unloading mechanism, recoil pipeline, sealing assembly, inspection door assembly, tank body, slag hopper, etc.

Working process: Sewage (or other raw water) flows from the front of the drum, through the drum, into the drum, and flows out from the bottom.

The suspended solids in the sewage stay on the rotating drum.

With the rotation of the drum surface, the trapped dirt is sent from the water inlet end to the discharge end on the other side, and is shoveled down by the discharge mechanism.
