Upgrade your sand filter to the Forty-X™ disc filter

Increase filtration capacity and performance in existing footprint

The Forty-X™​ Disc Filter is a high-rate tertiary filter that requires a fraction of the footprint required by traditional sand filters. Designed with unique woven media filter panels, the Forty-X Disc Filter uses an inside-out flow pattern that reduces backwash cycles and energy demand leading to lower lifecycle costs.

For applications requiring a higher solids loading capacity and greater hydraulic throughput, the Forty-X™ Disc Filter Armor series is recommended.  This innovative high-rate filtration device combines outside-in and inside-out filtration technologies within one filtration unit.  Influent water flows through an integrated pre-screen (outside-in) to woven stainless steel disc filter panels (inside-out), providing an effective and robust solution for challenging water and wastewater filtration applications.

The modular design of both the Forty-X Disc Filter and Forty-X Disc Filter Armor series 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.
