Abstract: | The potential for upgrading the microbiological reduction of sulfates and for decreasing the organic pollution levels in industrial waste-water by the adjustment of the COD/SO4 ratio was investigated. The experiments involved waste-water samples coming from industrial pig farming, baker's yeast production and organic dye manufacture. The results show that in the presence of Desulfovibrio desulfuricans both the objectives can be achieved by abating the disproportion between the content of sulfates and that of organic substances. |
