Table 4
BAT-AELs for total chromium and sulphide emissions through indirect discharges of waste water from tanneries into urban waste water treatment plants
| Parameter | BAT-AELs |
|---|---|
| mg/l(monthly average values based on the average of the 24-hour representative composite samples taken over a month) | |
| Total chromium (as Cr) | < 0,3-1 |
| Sulphide (as S) | < 1 |
