Autosep Sand Trap DF SWB/SWP
The wastewater entering the device flow into the integrated loosening chamber from where they are transferred to the filtering segment, where solid parts are separated. Depending on the model, the screenings are held by:
SWB: slotted sieve drum with worm conveyor.
SWP: Fixed, cleaned perforated sieve with worm conveyor and sweeping brushes.

Screenings held by the sieve are transported up to the draining-compressing segment, where they are washed and drained. After, the wastewater without screenings is gravitationally transferred to the centrifugal sand trap assembled under the sieve, where it is aerated in order to support light solid matter and fat floatation.

The sand trap is integrated with the fat trap, from which the flotate is transported outside the device. Sand collected on the bottom is transferred through the draining worm conveyor.
