Feb 01, 2016 · Sweep Factor is defined as:-(3) SF = A gas 0.25 e m 0 e x × F gas A cell Where SF denotes the Sweep Factor (min −1), A gas is the total cross sectional area of bubbles per unit volume (m 2 gas/m 3 gas), F gas is the gas volumetric flow rate (m 3 min −1) and A cell is the cross sectional area of flotation cell (m 2). As A gas is inversely propositional to bubble diameter (Walsh, 2012), smaller gas bubbles …

gas dispersion measurements in a flotation cell

Nov 01, 2003 · Gas dispersion properties were measured in a 50 L lab scale flotation cell, using these techniques. The cell was operated under batch conditions, two-phase system, (gas–liquid). The experimental conditions were modified altering the operating conditions in the cell: impeller speed and gas …

Sep 12, 2013 · Induced gas flotation (IGF) is a treatment process that clarifies wastewaters (or other waters) by the removal of suspended oil. The removal is achieved by introducing very small bubbles of air or other gases into the water or wastewater. The bubbles adhere to and enhance the buoyancy of the suspended oil which accelerates the rate at which the oil floats to the surface of the water where it can …

pulp and froth phases in gas processing - pace

Mar 22, 2010 · Gas hold-up is the volume of the gas in the pulp zone of a flotation cell. The volume of gas reduces the pulp volume and therefore decreases the residence time available for flotation. The gas hold-up depends on the amount of air added to the flotation cell and is a strong function of pulp viscosity

advances in flotation unit design for produced water

Mar 21, 1993 · The gas bubbles are formed by reducing the pressure of a gas saturated produced water stream. This produces a fine bubble dispersion which has been shown to remove smaller oil droplets than does conventional equipment. This patented process, called Hybrid Gas Flotation, allows for increased throughputs and improved effluent quality
