Abstract

In one embodiment, a method includes gasifying a fuel source using a first oxygen stream supplied from an air separation unit (ASU), discharging a gasifier blowdown from a gasification and scrubbing system configured to gasify the fuel source, generating a grey water from the gasifier blowdown, and biologically treating the grey water in a reactor using a second oxygen stream supplied by the ASU.
