Energy-Efficient External Rotary Drum Screen with Low Power Consumption | Green Technology

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 suspended matter in the sewage retained on the rotating drum, and with the rotation of the drum, it is sent to the discharging end of the other side from the inlet end, which is shoveled down by the unloading device.

The time relay in control cabinet controls the back flush solenoid valve to open and close periodically so that to clean the blockage between the drum bars.

The integral design, strong construction and high quality stainless steel material ensure the equipment can long-term operate with trouble-free and low energy consumption. Simple maintenance.
