PROCESS FOR TREATING OF LIQUID BY FLOTATION INDUCED BY FLOATING PARTICLES

摘要

Process for treating a liquid by flotation induced by floating particles that comprises a mixing step during which said floating particles are added to said liquid, a flotation step during which said floating particles rise to the surface of the liquid, and a step of separating said floating particles thus risen to the surface of the treated liquid, said process being characterized in that at least some of said floating particles have at least one flocculating polymer material attached to all or part of their surface, said process furthermore including no step of addition of gas and no step of addition of a free flocculating material not attached to said particles.
