    摘要： The invention refers to an apparatus for producing water saturated with air under high pressure and preferably intended for dispersion in flotation plants, which apparatus comprises a preferably standing cylindrical pressure vessel (21) which during operation to a controlled level is partly filled with pressurized water flowing through said vessel and out through an outlet in the lower part of the vessel and partly with continuously added compressed air, whereby during the passage of the water through the vessel (21) air is dissolved in the water. The supply of pressurized water to the apparatus is arranged at the upper part of the pressure vessel (21) by means of a spray-nozzle (24) or similar arrangement which splits the water flow. The spray-nozzle is so designed that at least part of the water flow sprays and essentially covers the inner walls, of the upper, during operation air filled portion, of the vessel (21) by means of a water curtain which portion is supplied with compressed air through a conduit (27) arranged in the wall of the vessel in this portion.

    摘要： Method for purifying a liquid by means of flotation at which the water to be cleaned as well as the dispersion water (or liquid) is fed to the lower part of a first long and narrow standing preferably cylindrical vessel (23) whereby in the water column defined by the form of the vessel a rising water current is achieved which gives to the particles or flocculations in the water column a rising movement which movement increases the flotation effect of the micro bubbles which are created at the dispersion nozzle as well as during the successive decrease in pressure which takes place in the water column and which bubbles by means of the design of the vessel will be given a high concentration, which vessel (23) at least at its upper open end is surrounded by a second open vessel (22) the edges of which reach higher than the upper edge of said first vessel (23) and at the lower part of which a pipe joint (32) is arranged for the outflow of the cleaned liquid and at the upper part of which a third vessel (29) is arranged for receiving of the separated impurities from the second vessel (22).
