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
