Dependable and effective mechanical solid separation using tried-and-true technology: compact design with integrated screens washing and pressing A special patented mechanism underpins the HUBER Fine Screen ROTAMAT® Ro1 operation, enabling the combination of screening, washing, transport, compaction, and dewatering in a single unit. The throughput can be independently adjusted to meet site-specific requirements based on the screen size (screen basket diameter of up to 3000 mm) and screen bar spacing (6 or 10 mm). All stainless steel components of the HUBER Fine Screen ROTAMAT® Ro1 are acid treated in a pickling bath. These 35° inclined screens can be supplied as tank-mounted pieces or put straight into the channels. Wastewater enters the inclined screen basket through the open end and passes through the screen. The bars in the screen basket hold in place objects that are suspended or float. In order to retain solids smaller than the bar spacing, blinding the screen surface creates an additional filtering effect.
The rake arm on the axle center begins to rotate when there is a difference in water levels upstream and downstream of the screen, which is brought on by screen surface blinding. Its tines lift the screenings to a position at twelve o'clock, clean the basket, and remove all of the screenings by entirely extending through the screen bars. The screens fall into the integrated screw conveyor-equipped trough that is positioned in the middle. After that, the rake is brought back to its 12 o'clock position. A movable comb removes the screens from the rake during this return movement, giving the tines one last cleaning. The screens are moved out of the trough and via the rising pipe by means of the conveying screw's rotational movement. The screens are dewatered and compacted without creating an unpleasant odor as they travel through the slanted pipe and are then released into the customer's container or another conveying equipment.

Fine-screen benefits include:
a) Low headloss and high separation efficiency
The screen area is significantly bigger than that of a vertical or steeply inclined screen because of the screen basket's form and 35° installation, which leads to a low headloss, high separation efficiency, and maximum throughput.
B) Constructed entirely from stainless steel
Because the machine is entirely composed of stainless steel and is pickled in an acid bath, corrosion is eliminated, requiring minimal maintenance.
c) Dependable, self-cleaning functionality
Full engagement of the rake's tines ensures positive cleaning of the entire screen surface. Even with extreme levels of pollution, the screen remains unaffected. Furthermore, a single flow channel ensures that the screenings stay continuously inside the basket (in front of the screen area); that is, during the cleaning process, the screenings are not removed from the wastewater and moved into the downstream flow that has already been cleaned.
d) Multiple roles integrated into a single system
Within a single, compact unit, the ROTAMAT® Screen completes the tasks of screening removal, transport, washing, dewatering, and compaction. An extra bagging unit ensures that the system will run without producing any unpleasant odors.
e) Installing outside
If necessary, the ROTAMAT® Ro1 can be offered with extra insulation in addition to frost protection for outdoor installations.
f) Repurposing
The ROTAMAT® Screens' design for further alterations, enabling the systems to be tailored to evolving needs. For instance, the integrated screening and washing system and the heating system can both be retrofitted.
g) Low upkeep
Not lubricated. Visual examination and routine checking are adequate.
