Strains degrading and decolorizing acid dyes, Nylosan red E-BL 150%. were isolated from natural system, was named as ARK3. The optimal culture conditions of temperature and pH were , 7.0, respectively. Growth rate of cells in conditions of aerobic shaking more than standing culture conspicuously increased, and optical density of those to strain ARK3 were found as 1.38 and 0.25 after 42 hrs. Decolorization efficiency in batch culture which used as immobilization media to natural zeolite was 15% after 6 hrs, while suspension culture was 5%, also its of immobilization and suspension culture were 90% and 85% after 48 hrs, respectively. Decolorization efficiency of air-lift bioreactor was more than 90% to a dilution rate of , but that was decreased as 70%, when the dilution rate was . Even though at maximum dilution rate of this study, there was not appeared \\\"wash out\\\" phenomienon of biomass. Decolorization efficiency was 97.7% at a dilution rate of , when influent dye concentration was . But if influent dye concentration increased as , even though MLVSS increased, that of treatment water decreased as 93%. Also, when influent dye concentration increased as and , decolorization efficiencies of treatment water abruptly decreased as 85% and 63%, respectively. Decolorization efficiency was more than 92% to the limit volumetric loading rate of hr, without regard to variation of influent dye concentration or hydraulic retention time. if volumetric loading rate was more than , at same condition, decolorization efficiency was lower decrease of retention time than increase of influent dye concentration.entration. |
