How does the Sepcon BAF Sewage System Work?
Stage 1: The Primary Settlement Chamber
In the first stage of sewage treatment, anaerobic breakdown takes place in the primary settlement chamber. The waste water is introduced and the solids drop to the bottom, becoming separated from the liquid.
Stage 2: Twin Aeration Chambers
The next stage of the waste water treatment involves aerobic breakdown. This takes place in the two side by side aeration chambers, where masses of naturally occurring bacteria inhabit specially designed filter media. The Sepcon BAF has two aeration chambers side by side to ensure that there is a the highest levels of treatment.
These bacteria are sustained with air, which is continuously supplied from a purpose-built pump in the unit’s top section. As the liquid flows slowly through the filter media, the bacteria feed on the waste and remove it from the liquid.
Stage 3: Final Settlement Chamber
In the last stage of waste water treatment, the liquid flows from the aeration chamber into the final settlement chamber. Suspended sludge consisting of bacteria is carried with the liquid into the settlement chamber and settles to the bottom of the chamber. The remaining treated liquid now meets the required standard to be safely passed out of the Sepcon BAF System.
