This study investigated the use of an electronic nose for on-line anaerobic reactor state
monitoring at the pilot-scale level and then upscaling to the full-scale level. E-nose indicator …

Anaerobic reactors in full-scale biogas plants often encounter process instability; thus, their
operational efficiency and further promotion remain limited. Process monitoring can be used …

This study aimed at analysing the utilization of an electronic nose (e-nose) to serve as a
specific monitoring tool for anaerobic digestion process, especially for detecting organic …

Biogas plants can effectively treat organic wastes from various sources and recover energy
from biomass for commercial use. However, anaerobic digestion (AD) can suffer from …
