Microscreen drum filter tertiary polishing plant

The microscreen is used when further solids and/or biochemical oxygen demand (BOD) needs to be removed:

  • Preventing damage to downstream processes
  • Improving efficiency of downstream processes
  • Reducing contamination to watercourses
  • Seperating effluents to enable recycling

The unique design of the drum filter maximises the surface area of filtration to achieve high removal efficiency with extremely low operating costs.


  • Water utilities and municipal wastewater
  • Industrial trade effluent

  •  Skid mounted options for temporary solutions
  • Choice of Form 2 or Form 4 control panels
  • Integral pumped backwash system fitted as standard
  • Collated sludge can be either pumped or gravitated, dependent on site levels
  • Optional colour finish can be specified to coordinate with other equipment on site to minimise visual impact

Cartridge based cloth/filtration system

  • One-size cartridge fits all models
  • Easy to change on site without the need for a service call
  • Polyamide or stainless steel cloths can be fitted
  • Interchangeable cloth cartridges available
  • From 20 microns upwards to provide flexibility on flow versus flux

  • Use of backwash wastewater to cleanse the cloth

Option of hire and trials:

Fast and flexible hire of WPL’s wastewater treatment units ensures that sites undergoing emergency reactive work, or planned refurbishment, can remain fully operational and within environmental consent. Whilst WPL’s full-scale operational trials provide a fast and effective solution, offering immediate enhancement to onsite industrial trade effluent treatment. This means full compliance is achieved as soon as possible, with no capital risk, putting your mind at ease while a permanent option is found.
