PRESSURE FLOTATION APPARATUS

摘要

A pressure flotation apparatus that realizes efficient adherence of microbubbles to flocks and prevention of short-circuit outflow from the tank of raw water having flowed out from a feed well, thereby attaining efficient flotation separation processing. The pressure flotation apparatus is one including a flotation tank composed of tank frame (1) and internal tank (2) and, disposed in the flotation tank, feed well (10) with its superior portion open so that a raw water containing microbubbles is fed to an inferior portion of the feed well (10), rises through the feed well (10) and is introduced into the flotation tank from the superior portion opening, characterized in that there is provided annular baffle (20) surrounding the superior portion of the feed well.
