A method of destroying a fluorocarbon compound includes regenerating an adsorbent to remove the fluorocarbon compound and to produce a regeneration fluid having a concentration of the fluorocarbon compound and directing the regeneration fluid to an electro-oxidation system. The method also includes applying a current to the electro-oxidation system to oxidize the fluorocarbon compound within the regeneration fluid and measuring a quantity of fluorides in the regeneration fluid to determine the progress of the removal of the fluorocarbon compound from the regeneration fluid.

Fluorocarbon destruction method

There is disclosed processes and systems for improving the efficiency of the separation of insoluble contaminants from a fluid in a floatation unit.

Methods and systems for enhanced dissolved gas floatation

A pump system includes a centrifugal pump having an impeller, a first inlet arranged to receive a first flow of liquid, a second inlet arranged to receive a flow of gas at a first pressure, the gas being soluble in the liquid, and an outlet arranged to discharge a second flow of liquid that contains the flow of gas solubilized therein. An injection pump has an inlet arranged to receive the second flow of liquid. The injection pump is operable to increase the pressure of the second flow of liquid to produce a high-pressure flow of liquid, and includes a discharge arranged to discharge the high-pressure flow of liquid.
