Forty-X™ Disc Filter Armor Series

High solids loading capacity and greater hydraulic throughput.

​The Forty-X™ Disc Filter Armor series is a high-rate filtration device that utilizes an integrated pre-screen and stainless steel disc panel that are designed to accommodate high solids loading capacities and greater hydraulic throughput. Forty-X-Armor Series.png

The modular design provides a flexible and dependable filtration solution for tertiary filtration, municipal, and industrial reuse/recovery, product recovery, process water filtration, and conventional filter retrofit applications.

 Armored to Protect

​Evoqua’s Forty-X™ Disc Filter Armor series combines outside-in and inside-out filtration technologies within one filtration unit.  Influent water flows through an integrated pre-screen (outside-in) to the disc filter panels (inside-out).  This innovative combination of two filtration technologies into one unit provides an effective and robust option for those difficult applications.


The integrated pre-screen is like "Armor" protecting the disc filter by providing initial filtration of large organic and inorganic materials.

 Features & Benefits

  • An integrated pre-screen to accommodate high solids loading and protect the disc filter by removing organic and inorganic materials. 
  • ​Woven 316 stainless steel flat media panels for greater hydraulic throughput.
  • Automated chemical cleaning system.
  • Easy to operate and maintain.
  • Modular design offers flexibility and expandability.
  • Suitable for retrofit of existing conventional filters.

 Operation of Integrated Pre-Screen

 Innovative Disc Filter Panel Design

Evoqua's woven optimum tertiary mesh (OTM) filter panel utilizes 316L stainless steel threads to create a weave that improves solids collection and rejection.  The panel configuration includes a robust, molded structural fram and a pressure -assisted seal allowing the panels to sustain and operate at a higher headloss and provides higher throughput when compared to other woven polyester flat panel disc filter designs.
