| abstract | The invention relates to a method for producing paper, in which a paper web (1) is pressed and dewatered on at least one revolving felt web (2), the felt web (2) being removed in a region of its circulation separated from the paper web (1) is treated by impurities with an acidic and / or basic cleaning solution by the cleaning solution of the felt web (2) is fed and discharged after sufficient residence time, and during this treatment by controlling a cleaning concentrate addition a predetermined p H range of the cleaning solution is sought and wherein, after this treatment, the cleaning solution is washed out of the felt web (2) and the felt web (2) is neutralized as necessary to a p H value close to 7. It is essential that the electrical conductivity of the cleaning solution is measured during the mentioned treatment for the removal of impurities and that the control of the cleaning concentrate addition to the cleaning solution is effected as a function of the measured conductivity of the cleaning solution, using a respective cleaning concentrate suitable, individual calibration. |
