MICROFLOTATION BY MEANS OF PRESSURE LIQUID

摘要

Appts. for the flotation of particles from waste water by expanding a pressurised liq. in which gas is dissolved under pressure in the waste water to form microbubbles comprises a vessel with two chamber sepd. by a partition which ends at liq. level: in the second chamber are means for removing foam consisting of particles and associated microbubbles from the liq. surface, and means for removing clarified liq. On or above the bottom of the first chamber is a nozzle device for providing the pressurised liq. with a dynamic increase in pressure immediately before expansion and releasing a rapid flowing widely devergin current of the liq. into the water.
