(JP9224656-A)      A process for the treatment of sewage containing selenium (Se) comprises: (a) microbially treating the sewage to reduce 6-valent Se present in the sewage to 4-valent Se and/or simple Se; and (b) separating any resulting liquid from any solid that is present. Also claimed is an apparatus for the treatment of sewage containing Se comprising: (i) means for microbially treating the sewage to reduce 6-valent Se present in the sewage to 4-valent Se and/or simple Se; and (ii) means for separating any resulting liquid from any solid that is present.    USE -   The process is especially useful for treating desulphurized sewage from power generating facilities.    ADVANTAGE -   The process enables effective removal of Se at a low cost.
