Scandinavian Biogas technology enables high utilization of the reactor volume, resulting in lower investments for new biogas plants and higher gas production in existing ones. Depending on the substrates and general circumstances, we can increase the gas production in the existing digester volume in wastewater treatment plants several times. When it comes to ethanol by-products, we reach levels of around 6Nm3 per m3 of digester volume per day. Scandinavian Biogas applies a mesophilic anaerobic digestion process, which is carefully optimized to yield the best stability, functionality and gas production.
While we keep the exact steps of the process for ourselves, the secret lies in combining a set of techniques, each developed over several years of R&D. Our people at our laboratory, located at Linköping University in Sweden, constantly develop and fine-tune these methods, to make them even more versatile and adaptable to the shifting conditions of the global biogas market.
In comparison to most producers, we put more focus on a few important areas:
- Mixing. Mixing means not just simply stirring the substrate. The process has to be sensitively adjusted to give the microbes the best possible environment.
- Ultrasound treatment. Unique in the industry, our ultrasound treatment helps the digestion by breaking apart organic structures in the substrate and facilitating for the microbes. Read more about the ultrasound treatment in the next section.
- Heating. Most biogas producers do not provide the best possible conditions for the mesophilic microbes to thrive – we do.
- Chemical balancing. We tightly control a wide range of trace substances to keep the micro and macro environment optimized.
- Monitoring. We can remote-control, in real time over the internet, the reactor environment. Should anything deviate from the optimal levels, we can correct it immediately to prevent a downturn in performance.
