The curved screens are robustly built and require a minimum of maintenance and attention. The raw wastewater is pumped over a curved, wedge wire, screen plate where separated particles slide down, due to gravity and the screened water leaves the screen via the outlet. For very heavy polluted wastewater, a vibrating screen plate can be installed in order to guarantee clog-free operation.
Screenings spend a long time on the relatively flat bottom part of the screen plate, allowing moisture to seep from the screenings.
Wedge is widest on the inside, so slots block more difficult.
Mesh is smaller than actual slot width due to curvature of the curved screen combined with the momentum of the coarse solids.
The screenings are guided by a chute during the fall into the deposit.
Creates enough height to place a container below the screen.
By adding a hinged cover it opens effortlessly as it includes a gas cylinder assisted swing-up opening.
Cleans large surface area. The screen can be equipped with a programmable spray cleaning device in case the wastewater contains fiber-like materials or fat. This spray arm cleans large surface area and is equipped with multiple high-pressure spray nozzles which is reliable and safe
