Different parameters are used to assess the efficiency of biogas plants. The most common parameters used in practice are VS destruction and COD reduction. Both parameters indicate the mass conversion of organic matter into biogas. During anaerobic operation more parameters need to be balanced e.g. nitrogen and sulphur. The mass flow balance can be used to assess the quality of the operation process based on sampling and analysis. In principle a quantification of mass transfer processes is only feasible with regard to mass flow balances. The anaerobic reactor is considered a "black box" with following interfaces: sewer gas, inlet and outlet [20]. The validation of measurements is facilitated by applying closed balances. In the following the balances of different anaerobic systems will be discussed with respect to the parameters nitrogen and sulphur and conclusions will be given for optimizing the operation of biogas plants.
