Division BAT 27 In order to reduce emissions to water from wood fibre production, BAT is to use a combination of the techniques given below.
United Kingdom
| Descriptions of the techniques are given in Section 1.4.2. | ||
| Technique | Applicability | |
|---|---|---|
| a | Mechanical separation of coarse materials by screens and sieves | Generally applicable |
| b | Physico-chemical separation, e.g. using sand filters, dissolved air flotation, coagulation and flocculationf1 | |
| c | Biological treatment | |

BAT-associated emission levels (BAT-AELs) for the direct discharge to a receiving water body of process waste water from wood fibre production
| Parameter | BAT-AELs(average of samples obtained during one year) |
|---|---|
| mg/l | |
| TSS | 5–35 |
| COD | 20–200 |
The associated monitoring is in BAT 14.
