Abstract
There is provided a system and a method for regenerating a material that reduce the incidence of scaling due to scale forming contaminants. The method may include reducing a temperature of a treated material exiting a wet air oxidation unit in a scale reducing heat exchanger prior to delivery of the treated material to a second heat exchanger which heats a source waste material comprising a scale forming contaminant therein with heat from the first treated material to form a heated waste material comprising the scale forming contaminant.
