Abstract

1. Apparatus for water purification and/or aeration by saturation of the raw water with pressurized gas and subsequently allowing it to depressurize in a floating vessel characterized in that upstream to the flotation vessel (3) there are provided in series a first injector pump (1), a feed pump (4) and a second injector pump (2), and that the product water outlet (35) of the flotation vessel (3) through a throttle valve (39) is connected with the driving medium inlet (11) of the first injector pump (1), the suction inlet of which being designed as a gas suction inlet and the outlet of which feeds the driving medium inlet (21) of the second injector pump (2), the suction inlet (23) of the latter being designed as a raw water inlet.
