Functioning:
The wastewater flows to the filtration part through the loosening chamber. Screenings held on sieve are removed with adjustable rotary brushes, which are automatically cleaned by the inertial sweeper.
The screenings are collected through the discharge mechanism, optionally connected to the Screenings Press DF PU. Wastewater, after solid parts removal, are transferred gravitationally to the centrifugal sand trap assembled under the sieve, where it is first aerated in order to support light and fat components floatation. Fat trap is assembled in the upper part, out of which the flotate is transported outside the sand trap. In the sand trap chamber sand and mineral elements sedimentation is carried out.
The sand collected on the bottom is transported with the air-water pump to the sand separator, where the sand is cleaned with water and compressed air. Cleaned sand is removed from the device with the diagonal worm conveyor.
