Chemical oxygen demand balance for the degradability of the liquid fraction (in grams of O2 based on a liter of effluent)
| Chemical oxygen demand (g O2) | Percentage of initial total chemical oxygen demand value | ||
| Initial state | Total | 134.9 | 100 |
| Dissolved | 54.6 | 40 | |
| Non-dissolveda | 80.3 | 60 | |
| Final state | Methane | 77.2 | 57 |
| Dissolved | 9.4 | 7 | |
| Non-dissolveda | 48.2 | 36 |
aNon-dissolved chemical oxygen demand was calculated from the measured values for total and dissolved chemical oxygen demand.
