Abstract (en)
[origin: EP2060674A1] The method involves emulsifying a medium in water locally by using a mixing element (7), and the process liquid is added in less than 5 minutes after the emulsifying process. The process liquid is added in less than 3 minutes, particularly less than 2 minutes, particularly less than 30 seconds after the emulsifying process. An independent claim is included for a device for executing a method for supplying medium for de-aeration or defoaming of process liquid, particularly in paper machine.
