EnviroLine - Envirorak - Bar Screen
Envirorak inclined screens, RKS series, are installed in channels. They fulfill both fine or coarse screening function. They can also be equipped with a fully integrated compactor for screenings dewatering (RKS/P series). The effluent passes through the screen, while the waste is stopped by vertical bars spaced apart according to the desired mesh. The screen start-up is programmed periodically, and by loss of head measurement caused by the accumulation of waste on the bars. The waste is lifted by means of multiple rakes drived by two lateral chains.

The screening waste is falling down directly into an integrated screw compactor installed transversally where it is compressed and dewatered. Screenings can also be conditionned into a continuous plastic bagging unit before beeing dumped into a container.

- Screenings discharge downstream
- Rake driving by lateral chains
- Simple design, reliable and sturdy
The structure of the screen is made up of two lateral frame structures fitting the required channel width. For channel installation, lateral rubber bands are sealing the gap between screen and civil-work. Envirorak screens are covering configurations up to 2 meter width and up to 10 meters discharge height.
The screen consists of fixed bars or Johnson profil whose space between them defines the screening mesh. This model with multiple rakes is particularly adapted for high loaded effluent and can be used either as a fine or coarse screen (3 to 60 mm bar spacing).
Rakes are fixed to lateral chains driven by toothed wheels. The precision of the upward movement of the rakes along the bar screen and then along the sliding plate guarantees a perfect scraping and raising of waste up to the point of discharge.
The screening waste can thus be unloaded in a container. They can be also transferred to a conveyor or a transversal screw compactor integrated to the unit (Version RKS/P).
