The invention is concerned with a procedure for removing volatile substances from water when distilling or evaporating water. The water to be purified, when it is feed water for a distilling apparatus (10), is heated to a high enough temperature or distillate or water to be evaporated or that has been evaporated and which already is at a high enough temperature is conducted into a vessel (31, 31a) communicating at it's top end with ambient air. Pure air is conducted into the same vessel (31, 31a) so that water and air are flowing in said vessel (31, 31a) in opposite directions. The pure air is arranged to discharge in the lower part of said vessel (31, 31a) through a dispersing means (33, 33a) in the form of microbubbles into the water and to carry along with it the harmful substances present in the water, whereby said harmful substances depart from the water by evaporation. The invention is furthermore concerned with apparatus for performing the procedure. |
