Gasified fluid supply device and flotation cell

Abstract

A gasified fluid delivery system, a flotation cell, and a method for treating suspended particles in sludge are described. The gasified fluid delivery system comprises a manifold and one or more tubular distributors connected to the manifold. The tubular distributors comprise one or more nozzles. The manifold is configured to distribute gasified fluid to the tubular distributors. The nozzles are configured to inject the gasified fluid into at least one of the following areas: a feed zone (F), a tamping zone (C), and / or a central zone (Z) of the tank.
