Abstract

A biofiltration system using peat as solid support inoculated with Thiobacillus thioparus (ATCC 23645) was developed for treating a gaseous stream containing high concentrations of H₂S. The inoculation systems allowed an efficient colonisation of the peat with T. thioparus, reaching 2.7 x 10⁸ cells g^-1 of dry peat. The biofilter reached an efficiency of 100% when fed with 355 ppm H₂S and an air flow of 0. 030 m³ h^-1. When increasing the inlet concentration of the acid, the removal efficiencies of H₂S decreased, reaching 90 and 60%, at 0.070 and 0.030 m³ h^-1, respectively. A maximum value for the elimination capacities of 55 g m^-3 h^-1 was obtained. Mathematical modelling based on Ottengraf's model enabled a prediction of the performance of the biofilter.
