Since 1993 Mahr Machinenbau have designed, manufactured and installed more than 250 bar screens worldwide. Their most recent innovation, the 2mm multi-rake, front return screen was designed to match the performance of the equivalent 6mm perforated screen.

The “MM2MM” multirake screen will prevent fine to medium size solids and floating waste from entering areas that may damage process plant.

UK Water Company’s discharge permits includes a condition specifically requiring a 6mm aperture screen however the Environment Agency has clarified that if an alternative design, is proven to perform as well, then the Environment Agency would review the Water Companies permit to allow this to happen.

The MM2MM Multi-rake bar screen with 2mm spacing has recently undergone rigorous testing at Chester-Le-Street WwTW and has been proven to have a capture rate that is at least equal to that of a 6mm perforated screen and with lower head losses.
