Disc Filter for tertiary treatment filtration

Designed for the filtration of large volumes of wastewater, the compact system has the capability to filter high flows (volumes) of liquids.


  • Utilities and municipal wastewater
  • Industrial trade effluent

Trial and hire – no capital risk

  • Trial equipment to prove the technology before investment
  • Extensive fleet of emergency hire equipment
  • Skid mounted option

Fast and effective hire of the Disc Filter offers immediate enhancement to onsite effluent treatment – bringing your site into compliance.

How the Disc Filter works

Waste water flows by gravity from the central drum through filtration segments. The filter drum is idle at the beginning of the filtration cycle – it does not rotate. Suspended solids get caught on the inner side of the segments covered by a filter cloth. As the cloth gradually becomes clogged with suspended solids, the water flow through the cloth decreases and water level inside the drum gradually increases. Water level probe activates the rotation of the filter discs and in the same time the backwash system is turned on.

High-pressure backwash rinses impurities off to the sludge manger. The water level inside the drum decreases, the flow is again at its peak with minimum water level. The filtration cycle repeats. Filtration proceeds continually without interruption.
