Screen higher flows in the same overall area as a conventional escalator screen and remove double the amount of screenings compared to a conventional 6 mm bar raked screen.
The FSM Alpha Beta screen with 6 mm perforated screen panels removes up to 82% of screenings from inlet works flows, preventing the build-up of screenings and resultant clogging of downstream wastewater treatment plant.
The FSM Alpha Beta Escalator screen is an innovative inlet screen and storm screen which allows higher hydraulic flows to pass through a fixed channel when compared to a conventional escalator screen. The FSM Alpha Beta Escalator screen can remove double the amount of screenings when compared to a conventional 6 mm bar raked screen.
The FSM Alpha Beta Escalator screen can be channel mounted or in a stainless steel tank as part of a Design for Manufacture Assembly (DfMA) package.

The FSM Alpha Beta screen with 6 mm perforated screen panels removes up to 82% of screenings, preventing the build-up of screenings and resultant clogging of downstream process plant.
The 30° angle of the screen below the water level provides nearly double the screen surface available for screening and enabling an increase in flow throughput without extensive civils.
Removing more solids than conventional screens, the FSM Frankenberger Alpha Beta screen can improve the efficiency of ferric dosing plants, and also protect Membrane Bioreactor (MBR) processes, helping to reduce the amount of phosphorus that needs to be removed before discharge to a watercourse. We can deliver fine screening, often down to 1-3 mm for MBR protection.
