Simple systems to characterize wastewaters - the case of biomethane potential

Abstract

Manometric methods, also called respirometers, have been used for decades to measure the main parameters defining the organic pollution of wastewaters, such as BOD (biochemical oxygen demand) or CoDb (biodegradable chemical oxygen demand). In fact, BoD (or CoDb) are not compounds but properties of wastewater. For known compounds, the theoretical CoDb can be calculated. For example, with an aerobic system and tertiary compounds (C, o, H):
