Your challenges

Polishing of effluent

By removal of the very small particles from effluent, it might be possible to reuse this water.

Heavy Duty design

The Disc Filter, thanks to the specific panel design, unlike the lower headloss allowance of other outside/in flow designs, our inside/out flow characteristic prevents problematic and costly overflow situations assuring that the filtrate is always accessible and in plain view.

Retrofit or upgrading of existing plants

The Disc Filter has been developed to make sure that existing filtration systems can be upgraded using the same concrete structures and existing tanks or simply by replacing the panels and the washing system.

How does it work?

The process

Water flows by gravity into the central drum and passes inside-out through filter panels on both sides of each disc. Solids are trapped inside; clean water flows out into the surrounding tank. Discs stay 65% submerged and remain still—until clogging raises the water level. Then, the backwash kicks in: discs rotate, solids are rinsed off with filtered water via easy-to-maintain nozzles, and discharged. Simple, smart, and self-cleaning.

Our positive impact

High efficiency washing system

The Disc Filter’s pleated media design offers quick release cleaning for efficient cycling without labor-intensive maintenance. This and other features improve the cleaning process while helping prevent media wear. The specially designed spray mechanism offers twice as many nozzles in a configuration that efficiently releases solids from the pleated media. The inherent simplicity of our configuration minimizes lifetime costs with fewer moving parts and lower energy demands for backwashing.

Replacing Discs

Each disc can be easily replaced in a matter of seconds, simply by loosening the locking screws. The panels can be easily and fast removed with no need of emptying the tank or disassemble the filter.

Modular design

Modular design with maximum flexibility for possible future expansion and/or different effluent requirements.
