A Drum Screen consists of a cylindrical wheel structural arrangement with radial supports known as spoke provided for strength and stability during rotation. Wide Screening wire mesh panels are fixed on the circumferential surface of this cylinder. Effective sealing between the rotary drum scree and concrete wall is provided by continuous neoprene rubber seals attached to the two Peripheral edges of the drum.

These can be coated with epoxy paint galvanized or given catholic protection to protect from corrosion.
