OXYGEN TREATMENT OF WATER AND PULP FROM PAPER OR CARDBOARD PRODUCTION |
| 摘要 |
Methods for seating water and gulp used in a paper or cardboard manufacturing process. Oxygen and nutrients are added to the water or pulp to increase the activity of aerobic bacteria resulting in a reduction of organic substances such as fatty acids. Alternatively oxygen alone is added to the water or pulp to reduce all both aerobic and anaerobic bacterial activity. |
