| (c) | Wet scrubber | ||
Table 10
BAT-associated emission level (BAT-AEL) for channelled dust emissions to air from drying
| The upper end of the range is 20 mg/Nm3 for drying of demineralised whey powder, casein and lactose. | ||
| Parameter | Unit | BAT-AEL (average over the sampling period) |
|---|---|---|
| Dust | mg/Nm3 | < 2-10 f1 |
The associated monitoring is given in BAT 5.
