Streamline BAF Precast Concrete Sewage System

The Streamline BAF has become synonymous with highly efficient waste water treatment systems over the last 25 years.
During this time Streamline Environmental have managed to achieve efficiency levels far in excess of any European Standards and thanks to our unique designs and simplistic maintenance, Streamline BAF Systems have helped thousands of homeowners to protect their surrounding environment with minimal maintenance costs.

How does the Streamline 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: The Aeration Chambers
The next stage of the waste water treatment involves aerobic breakdown. This takes place in the aeration chambers, where masses of naturally occurring bacteria inhabit specially designed filter media. The Streamline BAF has two aeration chambers 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 Streamline BAF System.
