Abstract
Disclosed are systems and methods useful in waste processing. Disclosed is the use of a regenerative thermal oxidation (RTO) unit for production of industrially useable steam. Disclosed are systems including a stripping unit associated with a regenerative thermal oxidation (RTO) unit so that the stripping unit provides fuel for the RTO unit and the RTO unit provides a stripping gas for the stripping unit. Disclosed are systems including an RTO unit providing steam to operate a vapor condensation (VC) unit.
