Internally Fed Drum Screen

Here at MAK Water, we’re a leading supplier of a range of water treatment, wastewater and sewage solution products. The REKO Internally Fed Drum Screen TM is a free-standing unit used for the separation of settling solids from waste water. It processes water by means of an internally-fed rotating drum screen. Requiring low investment and very little maintenance, this product is perfect for those looking for an efficient and affordable drum screen.

 

Working principle

The essential part of the REKO Internally-Fed Drum Screen TM is the rotating wedge wire or perforated drum, as this is used as the screening surface.

The polluted liquid flows into the drum via the inlet chute and passes the drum from the inside to the outside. Separated solids are retained on the inside of the drum, where they accumulate and dewater. The solids are then transported towards the discharge end of the drum by an internal spiral.

For automatic cleaning of the drum, a cleaning system with flat jet nozzles is mounted on the outside.

As the drum rotates, a spray arm with flat jet nozzles cleans the entire surface. The rotating drum and the cleaning system are guarded by a hinged cover with gas-springs.

The drum itself is driven by a directly coupled motor while the drive end of the drum is supported by a self-aligning flange bearing. The discharge end of the drum is supported by two support wheels. All bearings can be lubricated via grease nipples on the outside of the machine. Optionally, an automatic lubricating system is available.

ADVANTAGES OF THE REKO DRUM SCREENS TYPE TM:

  • A directly coupled motor drive is installed so the drum cannot slip.
  • Driving components, such as gear wheels, chains, belts, etc. are missing which means this driving principle is very reliable and requires very little maintenance.
  • All bearings can be lubricated simply through grease nipples on the outside of the machine.
  • Maintenance and replacement of the wheels and bearings is very simple from the outside of the machine
  • All parts in contact with the raw water are manufactured using stainless steel.
