Division BAT 3
United Kingdom
For relevant emissions to water as identified by the inventory of waste water streams (see BAT 2), BAT is to monitor key process parameters (including continuous monitoring of waste water flow, pH and temperature) at key locations (e.g. influent to pretreatment and influent to final treatment).

- f1
-
Monitoring frequencies may be adapted if the data series clearly demonstrate a sufficient stability.
- f2
-
The sampling point is located where the emission leaves the installation.
- f3
-
TOC monitoring and COD monitoring are alternatives. TOC monitoring is the preferred option because it does not rely on the use of very toxic compounds.
- f4
-
TN and Ninorg monitoring are alternatives.
- f5
-
An appropriate combination of these methods can be used.
