Hubert bandpass filter

The Hubert belt filter is a vertically placed filter that operates on the conveyor belt principle. Fine-mesh sieve panels - with openings from 2 to 10 mm - are mounted between two robust conveyor chains. As the panels move upwards, the water is effectively filtered, leaving solids behind on the sieve.

The removed debris is automatically cleaned at the top of the system with spray water and discharged via a flushing channel. All functional components, such as the drive unit, cleaning unit and drain, are located above the water surface at deck level and are safely shielded by a metal or composite protective cover. This makes maintenance easy and safe.

Thanks to its vertical design, it is ideally suited to locations with limited space or large water level differences. The screen is resistant to abrasive particles and aggressive (sea) water, and can be made of various high-quality materials - from coated steel to (super)duplex. Typical configurations include a recessed version or placement on a skie

Hubert belt filters are available for different flow patterns and can also be used for large tidal variations. The filters can also be supplied with a fish return system that removes fish gently and effectively.
