To meet the emission limits, four out of five successively measured values have to be lower than the emission limit
value and only one measured value may exceed the emission limit (maximum 50 % of the emission limit). The majority
of the parameters have to be determined with mass proportional homogeneous daily average samples. The parameters
temperature, TSS, pH, cyanide, sulphide, POX and sum of volatile aromatics (BTXE) are determined with random samples.
Waste water from the production of the following substances has to observe the following special
emission limits. The production specific emission limits are related to the installed production
capacity in tonnes.
