Division BAT 8 BAT is to monitor the key process parameters according to the table given below.
United Kingdom
| I. Monitoring key process parameters relevant for emissions to air | |
|---|---|
| Parameter | Monitoring frequency |
| Pressure, temperature, oxygen, CO and water vapour content in flue-gas for combustion processes | Continuous |
| II. Monitoring key process parameters relevant for emissions to water | |
| Parameter | Monitoring frequency |
| Water flow, temperature and pH | Continuous |
| P and N content in biomass, sludge volume index, excess ammonia and ortho-phosphate in the effluent, and microscopy checks of the biomass | Periodic |
| Volume flow and CH4 content of biogas produced in anaerobic waste water treatment | Continuous |
| H2S and CO2 contents of biogas produced in anaerobic waste water treatment | Periodic |
