ACTIFLO® Disc is a polishing solution designed to achieve high removal levels of suspended solids and phosphorus in municipal and industrial wastewater for water reuse. 

Actiflo® Disc’s configuration combines two efficient and compact treatment processes: a conventional Actiflo® phase, namely coagulation-flocculation ballasted bu microsand which allows for high-performance clarification, followed by a rotating disk filter polishing system for tertiary treatment.

With a total removal rate in excess of 95% for phosphorus and up to more than 99% for suspended solids, Actiflo Disc’s performance exceeds most discharge and reuse standards.


  • Very compact solution, easy to adjust to present facilities or sites to be refurbished.
  • Compactness: a footprint up to 80% lower than other conventional processes.
  • Very low water losses
  • Provides a protective barrier against parasites (ex: Helminth eggs).
  • Lower turbidity, suspended solids and reduces residual phosphate contents.
  • Gravity filtration
  • Continuous supply with no shutdown to wash filters


Thanks to its unique equipment design, ACTIFLO® Disc is applicable in several industrial and municipal situations.

Municipal applications

  • pre-treatment upstream of the membrane to produce drinking water
  • Wastewater treatment
  • Tertiary wastewater treatment for reuse in irrigation, replenishing the groundwater table or for urban use.

Industrial applications

  • Industrial wastewater treatment
  • Production of process water
  • Wastewater treatment for reuse
