Anaero Technology products

Our most flexible multi-stage digestation/fermentation model can be confiigured in several stage and all reactors also have recirculation capability giving hundreds of possible operational configurations. 4 1st stage digesters with individual feeders and heaters with 4 2nd stage reactors with individual heating and mixing and possible recirculating. Optional third, forth and more stages with recirculation between stages. Rocking the research boat with developments beyond biogas!

Anaero Technology offers lab-scale anaerobic digestion research bioreactors designed for automatic feeding of heterogeneous feedstock, replicating full-scale anaerobic digestion (AD) processes. These advanced systems incorporate components such as feeders, digesters, digestate tanks, and gas flow meters, ensuring precise mass balances within a gas-tight setup. The bioreactors support frequent feeding with automatic feeders capable of delivering small slurry volumes with precision. Mixed feeds with a 19% dry solids average, commonly entering full-scale food waste AD plants, have been used with these bioreactors for over 8 years. This approach helps address challenges such as foaming, inhibition, and optimal loading, which often skew results when managed manually. By leveraging real feed instead of diluted alternatives, these bioreactors significantly contribute to mixed feedstock research, including food waste and sludge. Equipped with gas flow meters and data loggers, the system is well-suited for advancing AD process research and optimization.

The Pegasus model offers three 5 litre reactors for bio-methane potential tests (BMP). It features robust stainless steel mixers, easy sample handling, and a second tank for digestate storage. The reactors are made of 316 stainless steel and have a large volume of 3 litres each. The Pegasus model also provides air-tight ports for accessing the reactors during the tests, allowing pH monitoring, nutrient supplementation, or sampling. Additionally, the stainless steel paddles ensure thorough mixing even for high solid substrates.
