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 obstacl

• Business Description: Champion Screens Manufacturing Company is a subsidiary of Champion
  
  Filters Manufacturing Company A 3 decade old organization specialized
  
  in design & manufacture of all types of Automatic Filtration &
  
  Screening Systems.
  
  Champion Screens produces wedge wire screens for virtually all screening applications.
  
  We have separate wedge wire screen making machinery for cylindrical screens & flat panels.
  
  We have the capability to produce screens as large as 4 meters in diameter X 6 meters length in one single piece construction.
  
  Wedge wire flat panels are made on flat panel manufacturing machine.
  
  So we can offer a truly flat panel instead of a re rolled slit cylindrical screen.
  
  Needless to say this offers better screening efficiency and better dewatering ability.
  
  Champion Screens have full fledged wedge wire manufacturing plant in house.
  
  Wedge wire (Vee Shaped or V wires) are manufactured in house.
  
  There are no limitations of size or shape of wedge wire.
  
  We can make vee shaped, v shaped, triangular shaped, trapezoidal wedge shaped, rectangular wedge, drop shaped wedge , wedge wires in any profile for optimum production.
  
  Cylindrical wedge wire screens are made by wrapping a wedge shaped (v shaped) wire on a cage of longitudinal rods.
  
  Each & Every intersection of this wedge wire & beneath support rods is welded.
  
  We make vee wire screens from Low carbon steel wedge wire, Stainless Steel grade 304 wedge wire, Stainless Steel AISI 316 wedge wire, Duplex Stainless Steel Wedge Wire, Super Duplex Stainless Steel Wedge Wire.
  
  We make wedge wires from wires as small as 0.25mm diameter to 18mm width & above if required.
