A hybrid flotation–membrane cell is pre-sented, which combines a membrane module submerged in a flotation cell. The solid particles are partially removed by flotation, while clean water is obtained from the membrane module. Fewer solid particles remaining in the dispersion are thus deposited on the surface of the mem-

flotation cell rotor. Traditionally flotation plant design blower selection and control has been based on using an oversized positive displacement blower, or an industrial fan, with any excess air discharged to atmosphere. While easy to select and design, this type of circuit contains inefficiencies especially when it comes to energy consumption.

The flotation cell has a particle collection regime in the lower half of the vessel and the loaded bubbles are recovered at the top of the vessel. The complete unit is a pressurized system. The DFR has a very low footprint due to the absence of a froth phase, the mass pull does not dictate tank size and the installation is on a single level

Nov 01, 2011In flotation cells, we add air, create bubbles of a certain size and speed that provide the surface area to do the flotation. The more bubbles and the smaller the bubble, the more surface area we have to do the work. This surface area we create is known as the surface bubble flux (Sb) and controls the kinetics of flotation.

This research presents three models of froth flotation that recognize flotation as an interfacial phenomenon wherein the rate of solids-surface-area removal is related to the bubble-surfacearea flux. These models use two streams, air and liquid, within the vessel. The solids within the column are associated with one, or both, of these streams. The procedures and benefits of batch tests for
