Method and Apparatus for Diffusing Gas into a Liquid

A method and apparatus for diffusing or reducing gas into a liquid is described. This invention covers several different methods for infusing or reducing gas into a liquid with a feedback loop that monitors specific parameters of the process and can vary controls to achieve a targeted value or keep within a range of values. The parameter of interest is the ORP (Oxidative Reduction Potential) and one way to determine that value is using an ORP sensor to directly measure it at various points in the process such as on the untreated incoming process fluid, right after infusing the reducing gas, or later in the process such as where the fluid is discharged back into the original tank in the case of a recirculating system or when it is discharged to the next phase of the treatment train.
