(JP10502411-W)      Treatment of an anaerobic digester effluent gas stream to render it usable as a fuel gas for a fuel cell or other power plant, comprises: (a) adding oxygen to the gas stream to form an O-enriched gas stream; (b) removing entrained particulates including water, solids and bacteria from the enriched gas stream to form a particulate-free, O-enriched gas stream; and (c) removing H2S from the gas stream from (b) via the Claus reaction to form a H2S-free gas stream suitable for use as a fuel gas source. Also claimed is a system for treating the effluent gas stream comprising: (a) a line for receiving the effluent gas stream; (b) a station connected to the line for adding oxygen to the gas stream to produce an O-enriched gas stream; (c) a station for receiving the enriched gas and removing particulates; and (d) a station for removing H2S from the gas stream.    USE -   The process is used for treating anaerobic digester effluent gas for use as fuel gas for a fuel cell or power plant.    ADVANTAGE -   The process removes H2S and particulates e.g. water, solids and bacteria. The process reduces disposal problems from wastewater treatment facilities including anaerobic digesters and produces a usable gas.
