Pneumatic flotation machine

Dec 10, 2021

A machine for dispersing gas bubbles in a liquid includes a horizontal series of adjacent flotation cells without baffles or mechanical gas distribution means. In each cell, an ejection device is mounted to expel a two-phase gas-liquid mixture into the cell. Liquid is pumped into the ejection devices so that the density and energy of the mixture at the point of ejection falls within Region I
