Dissolved air flotation DAF is a water treatment process for removing oils, solids, and greases from a water supply The process helps clarify wastewaters by eliminating different types of suspended matter DAF dissolves air in pressurized water then releases it at atmospheric pressure

Froth Treatment is a process by which water and fine solids are removed from bitumen froth produced in Extraction using hydrocarbon based gravity separation In a Paraffinic Froth Treatment facility, a paraffinic solvent is used as the diluent, producing a very clean final product that can be sold directly to market without an upgrading step

Introduction to Mineral Processing Froth Flotation Froth flotation is considered to be the most widely used method for ore beneficiation In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer

For flotation treatment systems, the application of the Nanoflotation technology is through the use of a surfactant and a patent pending high intensity mixing system The high intensity mixing is caused by the froth generated from the use of the surfactant The fluid containing the solids passes through a high intensity mixing zone which

FROTH FLOTATION So many variables influence flotation that it will be long before every one of them can be investigated and its influence on the process determined The froth flotation process was patented by E L Sulman, H F K Pickard, and John Ballot in 1906, 19 years after the first cyanide process patents of MacArthur and the Forests
