Real Time VFA Monitoring to Increase Biogas from Anaerobic Digestion for Heating Buildings

This research project aims to improve biogas production by monitoring volatile fatty acids (VFAs) in real-time during anaerobic digestion (AD). It focuses on using VFASENSE technology to make AD systems more stable and efficient.

VFASENSE includes a VFA analyser and solids separator, which provide automated, continuous monitoring of key VFA levels. This data helps keep the process stable and increases biogas production, especially for creating biomethane used in renewable energy, such as heating buildings.

The project is based in Neath Port Talbot, where sustainable energy solutions are needed. Real-time VFA monitoring will increase biogas production, helping to reduce reliance on fossil fuels and support the move to net-zero buildings. The project will also help cut greenhouse gas emissions and improve air quality. A major water utility partner will help implement the technology at its wastewater facilities to further increase biogas production.

This research supports regional goals for sustainability, economic growth, and environmental improvements, with plans for continued industry collaboration and long-term use of the technology.
