ABSTRACT
In this research which was performed with bench Scale, Adsorption of Cr(VI) from Industrial wastewater was studied & biological method of Activated sludge batch flow reactors utilized. This study indicated that Cr(VI) at first adsorped with cell walls of bacteria & then after Sedimentation it was intered to sludge & finally was removed from effluent. In this study Cr (VI) adsorption pattern was according to FreundlichIsoterm. The COD of synthetic wastwater was 3000 mg/L & Cr(VI) added to the reactors in three different stages with the Concentration of 5,10& 25mg/L.
In the 1st to 3rd stage with 10,8.5 & 9 hrs detention time Cr(VI) adsorption ratio on MLSS was 88%, 70% & 95% respectively.
According to the condition of this study Cr(VI) had no toxic effects on Activated sludge microorganisms in the reactors and the rate of microbial synthesis was increased.
