Abstract

Our research work focused on the applicability of dielectric measurement methods in wastewater-sludge treatment processes. On the one hand, we wanted to investigate how the soluble chemical oxygen demand (SCOD) - a key characteristic in sewage sludge utilization - changes due to the different sludge pre-treatment processes, and whether these changes are in connection with the dielectric behaviour of the material matrix. In addition, we also investigated whether the anaerobic digestion of sewage sludge, as a bio-energy production method can be monitored by measuring certain dielectric properties. The experimental results revealed that there is a strong correlation between the change in SCOD of different types of wastewater sludge that occurs due to the applied pre-treatment methods and the dielectric constant (at f=450 MHz frequency), and we also found connection between the nascent biogas yield and the dielectric behaviour of the fermentation medium.
