Abstract

In a microbubble injector usable to separate materials of different density by flotation, a deflector wall deflects radially a flow of water exiting under pressure from an injector hole and containing dissolved air at the saturation concentration. This procures cavitation which is localized at the edges of the hole and which generates the required microbubbles of air downflow thereof.
