What is Biofiltration of high concentration of hydrogen sulphide using Thiobacillus thioparus about?

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 H 2 S. The inoculation systems allowed an efficient colonisation of the peat with T. thioparus , reaching 2.7 )/10 8 cells g (1 of dry peat. The biofilter reached an efficiency of 100% when fed with 355 ppm H 2 S and an air flow of 0.030 m 3 h (1 . When increasing the inlet concentration of the acid, the removal efficiencies of H 2 S decreased, reaching 90 and 60%, at 0.070 and 0.030 m 3 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.
