Autosep Sand Trap DF SB/SP/KP

Autosep Sand Trap DF SB/SP/KP is a multifunctional mechanical sewage and industrial wastewater treatment device. The device structure enables efficient separation of both, screenings as well as mineral elements and flotate.

The wastewater stream is first slowed down in the loosening chamber from where it flows to the filtration segment, where solid bodies are separated. Depending on model selected, the screenings are held by:
SB: Rotary slotted sieve drum with worm conveyor.
SP: Fixed, cleaned perforated sieve with worm conveyor and sweeping brushes.
KP: Slotted grid with sweeping combs.

Sieve/drum/grid automatic cleaning system is enclosed depending on wastewater level increase outside the device. The screenings are additionally cleaned, and in SB and SP devices are also drained in their compressing-draining segments. The wastewater filtered from solid elements flows to the rectangular sand trap chamber, where it is aerated, which supports light elements and fat floatation. The sand held in the sand trap is moved by the worm conveyor to the collection chamber. The upper part of the sand trap is equipped with sweeper, which transports fat to the chamber, from which it is pumped or transferred gravitationally.
