CST rotary drum screens consist of a wedgewire drum inside which is an internal feed tank. Flow passes into the internal feed tank and overflows the weir. The internal feed tank has the function of controlling velocities and reducing the force of the flow onto the wedgewire drum.
The effluent water flows on to the screen face and we aim to dewater between the “3” and “6” o’clock positions. The effluent waters pass through the element under gravity, trapping the solids on the screen face whilst the cleaned liquor passes through the screen element. The collected solids are discharged via the screen drum mouth.
