The removal of biodegradable organic substances is a very important aspect of evaluation the treatment efficiency in a wastewater treatment plant (WWTP). The amount of oxygen consumed by microorganisms to oxidise organic substances is characterised by(More)
A biochemical oxygen demand (BOD) biosensor for effective and expeditious BOD(7) estimations was constructed and the non-steady phase of the output signal was extensively studied. The modelling approach introduced allows response curve reconstruction and a curve fitting procedure of good quality, resulting in parameters indicating the relationship between(More)
