Abstract

1. Process for maintaining a fine gas dispersion in liquids, wherein the gases are fed into the upper half of a vertically arranged circulation device under simultaneous mechanical revolution with a defined velocity of flow and by defined hydrostatic pressure, characterized in that the produced microbubbles are transported against their lifting force and with a greater velocity of flow in the down stream than in the up stream into the lower horizontal part of the device and in that pulsations and microwhirls are produced in the riser part of the device and afterwards an outgassing of the liquid takes place.
