HUBER Fine Screen ROTAMAT® Ro1 Reliable and efficient mechanical solids separation with well-proven technology

HUBER Fine Screen ROTAMAT® Ro1 units are either installed directly into the channels, or are supplied as tank-mounted units, with an inclination of 35°.

The wastewater flows into the open end of the inclined screen basket and passes through the screen, where floating and suspended materials are retained by the screen bars. As the screen surface becomes clogged, an additional filtering effect occurs, allowing solids smaller than the bar spacing to be captured. When a certain water level upstream or differential between upstream and downstream of the screen is reached, caused by the blinding of the screen surface, the rake arm positioned on the axle center begins to rotate.

The tines of the rake, which extend fully through the screen bars, clean the basket by removing all the screenings and lifting them to the 12 o'clock position. The screenings then drop into the centrally positioned trough, which is equipped with an integrated screw conveyor. The rake is then returned from the 12 o'clock position, and during this return movement, a hinged comb pushes the screenings off the rake, ensuring the tines are also cleaned. As the conveying screw rotates, the screenings are transported out of the trough and conveyed through the rising pipe.

As the screenings are conveyed and compacted within the inclined pipe, they are dewatered without generating any odor nuisance. Once dewatered, the compacted screenings are discharged into the customer's container or a downstream conveying unit for further handling.
