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.

Abstract: A wastewater filter includes a vessel having a bottom and a side wall that cooperate to define a filter space. A first filter media is positioned within the filter space to define a first media layer, and a second filter media different from the first filter media is positioned within the filter space above the first media layer to define a second media layer, the first media layer and the second media layer cooperating to define an interface plane. A draft tube is positioned within the second media layer and has a first end positioned a first non-zero distance above the interface plane, and a second end disposed a second non-zero distance from a top surface of the second media layer. A backwash fluid line is positioned to inject a backwash fluid into the first filter media, and a backwash gas line is positioned to inject a backwash gas into the draft tube.
