The ADI-BVF® reactor is an anaerobic digestion system that offers very stable, robust wastewater treatment and biogas generation under a wide range of operating conditions. ADI Systems is the inventor and exclusive provider of this patented* technology, which has been installed in 135 full-scale applications around the world. Our experience with low-rate anaerobic digestion is unmatched in the wastewater treatment industry.
The ADI-BVF® reactor treats wastewater streams with moderate to high concentrations of organics (COD/BOD), suspended solids, and fat, oil, and grease (FOG), typically without the need for primary treatment. The technology can be configured as an in-ground earthen basin or an above-ground tank based on space availability. It is sized to work at low volumetric loading rate conditions, and designed to handle variations in wastewater flows and characteristics and maximize biogas production. This makes the ADI-BVF® reactor an ideal choice for treating wastewater from a variety of industries.
The ADI-BVF® reactor can serve as the workhorse for your wastewater treatment plant and offer the following benefits:
