Grinder & Screen Package | Discam

Supplier: NOV Australia

The Discam is a unique new grinder and screen package, which offers a much more effective and low maintenance alternative to handling screenings than conventional systems.


With the ability to capture up to 95% of solids at 5mm or 9mm aperture sizes, this innovative solution combines the self-cleaning Discreen with a high torque Muncher.  No manual attendance or cleaning is required and disposal costs for handling debris extracted by traditional screening processes is eliminated.

The Discam is constructed using a series of shafts, two of which are fitted with interleaving cutters and spacers to give ‘positive displacement’ solids grinding, whilst the remaining shafts are fitted with overlapping and intermeshing discs.

Easily retrofitted into existing sewage pump stations or inlet works, as well as installed in new build facilities, this high performance package is suitable for almost any type of waste water facility.

Features and Benefits of the Discam Grinder and Screen Package:

  • Power savings, elimination of manual handling and associated transport costs, odour control and automated operation are all achieved when installing a Discam to replace conventional screening systems to existing or proposed submersible pump stations
  • Intermeshing discs give a self cleaning screen, no cleaning required
  • Ability to remove up to 95% of solids at the given aperture sizes
  • The Muncher® allows liquid to pass through the cutter stacks, filtering, trapping and macerating the entrained solids
  • Lower cutter tip speeds dramatically reduce impact load
  • Slow speeds also ensure low noise and vibration and good abrasion resistance
  • Screening apertures at 5.5 and 9.0mm available
  • 1000mm, 1500mm and 2000mm channel depth options
