Rotary Drum Screen
in-channel (Suboscreen)
The Suboscreen from Johnson Screens is a self-cleaning, in-channel, semi-submerged rotary fine screen capable of handling high flow rates and is suitable for both municipal and industrial applications. The influent entering the Suboscreen changes direction through 90 degrees as it exits the screen resulting in a high capture of solids.
The self-cleaning rotary drum is installed semi-submerged in a channel resulting in a smaller foot print compared to competing screens. The Suboscreen includes an integral drainer screw press for screenings washing, dewatering and discharge.
The operation of the Suboscreen is normally linked to the level differential between the upstream and downstream levels in the channel.
The Suboscreen is capable of handling flow rates from 1,440 m³/hr to 14,400 m³/hr through a single unit. Slot sizes range from 0.5 mm to 6 mm on the Vee-Wire® models and 2 mm upwards on the perforated plate and mesh models.
