Separation of food waste

Optima have a range of Internal Fed Rotary Drum Screen sizes which we market under our RDS product range. The RDS machine consists of a rotating wedge wire drum with slots starting from 0.10mm up to 10mm which run down the length of the drum allowing for screening from inside to out.

This product is used for solid / water separation which usually consist of more dense particles that need to be removed from the effluent. The effluent enters the inside of the rotating drum through the feed inlet and then passing over the distribution weir on to the drum surface. The particles and water separate as the drum rotates with the solids staying on the screen and passing down the length of the drum helped by internal flights or a continuous scroll.

The solids will then discharge into a skip or other machinery for further treatment. The screened liquid travels through the drum before leaving through the liquid outlet at the bottom of the machine. The RDS machine also contains an external pressurised water spraying system to help keep the drum clean and avoid clogging.
