Division 12.2 Water consumption and waste water discharge
United Kingdom
General techniques to reduce water consumption and the volume of waste water discharged are given in Section 1.4 of these BAT conclusions. Indicative environmental performance levels are presented in the table below.
Table 26
Indicative environmental performance levels for specific waste water discharge
| The amount of raw materials refers to gross tonnage. | ||
| The specific waste water discharge level does not apply to the production of polyols. | ||
| Specific process | Unit | Specific waste water discharge (yearly average) |
|---|---|---|
| Potato processing for the production of native starch only | m3/tonne of raw materials f1 | 0,4-1,15 |
| Maize and/or wheat processing for the production of native starch in combination with modified and/or hydrolysed starch | 1,1-3,9 f2 | |
