<p>METHOD AND APPARATUS FOR MICROFLOTATION BY MEANS OF PRESSURE LIQUID This invention relates to flotation treatment of a first liquid in a container for cleaning said first liquid from contaminating particles by upward injection into said first liquid of a pressurized second liquid containing gas dissolved therein under pressure, whereby dissolved gas will be liberated from said second liquid by the expansion thereof in said first liquid and spread as minute bubbles into said first contaminated liquid to entrain and carry contaminating particles to the surface of the liquid in the container, wherein said second liquid is subjected to a dynamic pressure increase immediately before the expansion thereof and is spread upward into the first contaminated liquid in a substantial divergent, homogeneous fast flowing flow for effectuating the initiation of the generation of gas bubbles only when the injected second liquid is well distributed in the contaminated liquid.</p> |
