Emission levels

as defined by the technical guidelines for preserving the quality of air (TA-Luft) discharged by a system. Emissions are given as the mass of materials emitted with regard to the mass per unit volume (g/m3 or mg/m3), mass of the emitted materials with regard to the time as mass flow (kg/h or mg/h) or ratio of the mass of the emitted materials to the mass of the products produced or processed as a mass ratio (kg/t or g/t)
