Research Abstract

The health impairment caused by ingestion of the arsenic in groundwater is serious especially in Asian areas. In order to remove arsenic in groundwater by coagulation or adsorption, arsenite in groundwater needs to be oxidized to arsenate.
In this research, arsenite-oxidizing bacteria are enriched from activated sludge, then 16S rRNA gene analysis was conducted. It was suggested that Rhizobium sp. is responsible for arsenite oxidation. The optimum conditions for arsenite oxidation by the bacteria were pH 7 and 30 degrees Celsius. For developing an innovative arsenic removal apparatus without aeration, oxidizer, and flocculant, a Down-Flow Hanging Sponge reactor with fixed arsenite-oxidizing bacteria was examined. As a result, when the inflow concentrations of arsenite and ferrous iron were 0.5 mg/L and 25 mg/L, respectively, the average arsenic removal efficiency was about 95 %. This efficiency was correspondent to the water quality standard for drinking water value of 0.01 mg/L.
