This paper presents current respirometric methods for general biological control using techniques developed for application in wastewater treatment, particularly for the control of the activated sludge process. It also presents recent developments of this method for application in treatment systems of Constructed Wetlands. New methods developed in the Engineering Laboratory (Lisa) at the University of Trento (Italy) are described. The methods use two distinct lab methodologies for respirometry application in Constructed Wetlands. The first one characterizes soil bacteriological activity measuring O2 concentration in the gaseous phase and the other one measures O2 concentration in watery phase.
