The TA-luft (Technical guideline for air pollution levels) is the general German regulation for the protection of emmissions and immissions. It includes the threshold values for the emission of pollutants and serves as a guideline for the regional authorities in the approval of industrial or commercial systems that are subject to authorization. For installations subject to approval, the building authorities may require that operators adapt their TA-luft values to the threshold values for clean air. Our systems enable you to comply with these regulations in a safe and durable manner.
All the statistics shown here are taken from the TA Luft BMU Web page of 24 July.
Inorganic gaseous substances
The following threshold values are applicable to inorganic gaseous substances. Reference is made to mass concentrations or alternatively, mass flows with maximum waste gas thresholds not to be exceeded.
Amongst others: Arsine (AsH3), hydrogen phosphide (PH3)
Max. mass flow per substance 2.5 g/h
Max. mass level per substance 0.5 mg/m³
Amongst others: Chlorine, fluorine and its inorganic gaseous compounds, to be indicated as hydrogen chloride (HCl), hydrogen sulphide (H2S), hydrogen bromide (HBr)
Max. mass flow per substance 15 g/h
Max. mass level per substance 3 mg/m³
Amongst others: Ammonia (NH3), inorganic chlorine compounds, to be indicated as hydrogen chlorine (HCl) - if not included under Class or Class II.
Max. mass flow per substance 0.15 kg/h
Max. mass level per substance 30 mg/m³
Amongst others: Sulphur oxides, to be indicated as sulphur dioxide (SO2), nitrogen oxide to be indicated as nitrogen dioxide (NO2)
Max. mass flow per substance 1.8 kg/h
Max. mass level per substance 0.35 g/m³
Organic gaseous substances
The following threshold values are valid for organic substances in waste gas, except for organic dust substances:
Max. mass flow 0.50 kg/h (indicated as total organic carbon)
Max. mass concentration per substance flow 50mg/m³ (indicated as total organic carbon)
Total dust, including fine dust
The following threshold values are valid for dust emissions in waste gas:
Max. mass flow per substance 0.20 kg/h
Max. mass level per substance 20 mg/m³
Even with a mass flow of 0.20 kg/h, waste gas mass levels of 0.15 g/m³ should not be exceeded.
