ABSTRACT

Disclosed herein is a process for recycling water in a cellulosic conversion process that comprises selecting process stream(s) that may contain reduced levels of inhibitors and subsequently subjecting the stream(s) to a treatment process to produce treated water. The treated water is thereafter recycled to the cellulosic conversion process, associated utilities or the seal water system. The process streams selected for treatment may comprise less than 5 wt% organic content and/or less than 5 wt% inorganic content. The process of the invention comprises at segregating process streams based on their treatment requirements. The segregated process streams may be sent to respective separate treatments selected from anaerobic digestion, aerobic digestion, physical separation and chemical treatment. More... »
