<p>An ionizer (1) is of the type comprising shear means for subjecting water to shear and air impulsion means (23) for bringing air into contact with the sheared water. Lower operating noise, less frequent maintenance and reduced water consumption are provided by fabricating the shear means with a plate (31/33), a drive (37) for rotating the plate (31/33) and means (39/41) for spraying water onto the plate (31/33) whilst it is rotating. As well as producing air rich in negative ions, the ionizer also humidifies the air. <IMAGE></p> |
