Functional Description

Sewage enters the pre-treatment chamber via gravity or vacuum, where it is macerated before entering the bioreactor.
In the bioreactor, wastewater moves in a serpentine path for maximum contact time and treatment. Sludge is recirculated to the pre-treatment tank.
After biological treatment, water flows into the settling chamber where remaining solids are removed and returned to the pre-treatment chamber.
Treated water is sterilized with chlorine or UV light before being discharged overboard.
