Engineering & Technical Specifications Airaflo Biofiltration System 1. Containment Odors are emitted from air streams with high concentrations of VOCs, sulfur and nitrogen compounds. Odor sources in the conveyance or treatment process must be located and contained. The odorous gases can then be ventilated from the source to Airaflo modules. 2. Ventilation Depending on the concentration of odorous compounds and the volume of air to be extracted from each source, ventilation is achieved via ducting and/or extraction fans. Pre-assembled Pod ___________________ Excellent performance across broad range of odor producing compounds _______________________ Long media life _______________________ Passive system, no power required _______________________ Prepackaged modules for easy installation _______________________ Built-in pH control _______________________ Built-in condensate drainage system _______________________ 3. Airaflo Biofiltration The waste airstream is directed to the interior bottom of the modules. The airstream flows through the recycled seashells, which provides pH control, and then through the granular high-density peat media. Beneficial bacteria reside on the peat media which provides optimal treatment through high porosity, water retention, high cation exchange capacity, high buffering capacity and a large surface area.
