Abstract

The bacterial biomass adsorption technology  is able to removing heavy metals from wastewater.  In this paper the isolation and selection of bacterial strains residual galvanic plant was performed,  four isolates were resistant to heavy metals, of which the AR-1 strain has the largest adsorptivity chromium (VI).  Biosorption experiments showed that the biomass obtained from the AR-1 strain is able to remove 90,1  % of chromium (VI)  in  the standard solution studied to a pH value of 6 units and a mass of adsorbent for 0,6 g·dm-3;  however, in a real womb  with 1,16 mg·dm-3 is  achieved  the concentration  decreasing  to 0,23 mg·dm-3, which corresponds to a removal percentage of 80,1 %.

Keywords: chromium, biosorption, waste waters, pollution, heavy metals.
