Process Parameter Study of Ferric Production in an Immobilization Bioreactor

Abstract:

Fe(III) from biooxidation can be used in different industrial processes, such as hydrometallurgy, treatment of acid mine drainage and removal of H₂S from some industrial waste gases. Many researches showed that the immobilization of the iron-oxidizing cells is helpful to increase the Fe(II) oxidation rate. In this study, a moderate thermopile Sulfobacillus sibiricu(S.s) is immobilized and the polyurethane foam is chose as the supporter. A reactor is established for testing the capability of the immobilized bacteria and the optimum reaction conditions are investigated. The experimental results show that under the conditions that the initial concentration of Fe(II) is 10 g/L, the dilution rate is 0.165/h and aeration rate is 300 L/h, the maximum oxidizing rate of Fe(II) can be reached.
