The wastewater flowing in is conducted to the perforated filtrating section. Depending on the separation effect assumed, the perforation applied may be of 1,0-10,0mm clearance. Cleaned fluid is transported to the lower tank, from where it is gravitationally transferred outside the device.
The screenings held on the sieve are removed with adjustable rotary brushes, which are automatically cleaned by the inertial sweeper. The screenings collection is performed through the discharge mechanism, which may be optionally equipped with Screenings Press DF PU. Should the fat screens be used , an innovative sequential perforation cleaning system may be applied.
