A basic understanding of column flotation operation is essential in order to recognize the critical function of the gas sparging system a column flotation cell is basically a cylindrical vessel with a large heightto diameter ratio gas is introduced near the bottom of the cell through a gas distributor system the dispersed bubbles rise.

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 twophase gasliquid 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.

Removal Of Fine Particles From Water By Dispersed Air

A theoretical treatment is presented which attempts to quantify the benefits obtained by using smaller bubbles or larger particles in dispersed air flotation the limited experimental data obtained so far suggest that the theory is sound particularly in its prediction of the effect of bubble size.

Odm Dissolved Air Flotation Equipment Wastewater

Air flotation is a dissolved air system that generates a large number of fine bubbles in the water so that the air adheres to the suspended particles in the form of highly dispersed tiny bubbles resulting in a state where the density is less than that of water.

dispersed air flotation units dispersed air flotation involves the generation iof air bubbles either pneumetically or by mechanical meansin both cases relatively large air bubbles are generatedin order to control the size and stability of air bubbles frothere are added to the flotation.
