Forty-X™ disc filters use pleated, woven media in a unique, inside-out configuration taht provide maximum disc filter performance at the same time as easily rejecting troublesome, inorganic materials.

At the heart of each Forty-X™ disc filter, individual media panels with integral frames support the woven media and ensure the geometry of the pleated surface. The media panels have a moulded, one-piece construction with structural stiffeners through the center of the panel area. The unique pleated design reduces the opportunity for fabric tear-out and effluent contamination and increases the true cloth area available for filtration by 40% over flat panel designs. This gives the Fory-X™ disc filter a more sustainable operation in terms of throughput, better feed distribution, and fewer backwash cycles.

In operation, influent flows through openings in the central drum and into the centre of each media panel. It then flows out through the filter media as a high-quality filtrate, providing and inside-out flow, which captures solids on the inside of the panel, making them easier to remove during backwashing cycles.

The Forty-X™ disc filter configuration minimises lifetime costs with fewer moving parts and lower energy demands for backwashing. Wind-safe sliding covers provide easy access to the interior, for inspection of the media panels, quick release spray nozzles and the centralized lubrication block. The filtrate is always accessible and in plain view.

The Forty-X™ disc filter frame-only design is an ideal drop-in retrofit for existing traveling bridge filters and can also be easily retrofitted to most other conventional filtration system. This is because it has an exceptionally small footprint relative to the high volume filtration capacity of the filter. The micron-rated media panels can be changed-out when filtration requirements change.
