CHAMPION Rotary Drum Screen
Quick Overview
Rotary Drum Screens with independent operation
•Suitable to be installed in each channel and in every condition
•Pre-treatment of Domestic & Municipal Waste Waters
•Solids Recovery & Processing from Industrial Effluents
•MBR Membrane Bioreactor Inlet Screening

The necessity was to design one equipment to be installed in each channel and in every condition; for example:

Absence of lateral channel “bypass”
Big sizes solids and/or longs fibres present in the effluent
High solids concentration

CHAMPION drum screen was designed without any bearing and any fix or rotating arm in the lower part . Screen area is totally free with big advantages not only for the incoming solids, but also concerning head loss.

CHAMPION Rotary Drum Screens - Operation

CHAMPION Rotary Drum Screens are integrated machines consisting of a screen, a screw conveyor and compactor. During operation, solids within the incoming flow will enter into the drum screen and progressively collect into the screen mesh and cause it to gradually blind. The upstream water level will rise and at a predetermined level, the drum screen and screw conveyor will activate and rotate immersing a clean section of the screen into the effluent. During rotation the solids or screenings will become inverted and then fall into the screw conveyor. Spray nozzles and a roller brush fixed to the periphery of the drum screen will clean away any residual solids from the mesh.

Another big advantage is also that when the drum will stop because the reduction of the effluent level, the screw conveyor will continue to rotate for a certain time to lift up immediately all the solids until the compaction zone. The hopper inside the drum will be always free and also in case of effluent entering inside the hopper, the solids will not be rejected in the channel.

The screenings are conveyed, compacted and dewatered and depending upon the solid properties, a volume reduction of around 40% DS or greater can be achieved prior to disposing the screenings into a skip or wheel bin.

A jet wash facility in the compaction zone will break down and remove faecal and other semi-solid or soluble matter and return it to the inlet flow. Additional jets can be installed in the transport zone to meet higher specifications of organic solids removal. Faecal matter washing efficiencies greater than 90% and screenings weight reduction of 50% can be achieved.

The compactor and wash system can be omitted to suit requirements such as CSO applications where the screenings are returned to the downstream sewer. CHAMPION drum screens can be supplied for direct installation into a channel or as a complete package inside a stainless-steel tank with or without the option of a bypass rake screen.

Continuous bagging systems are available to receive screenings and abate odour, the screenings can then be sealed without any personal contact. Any possibility for the big size solids to find some possible obstacles
