hydrogen sulfide (H2S) removal of minerals in the media using Thiobacillus thioparus TK-1 in air suspension biofilm reactor (BAS) has been studied to evaluate the relationship between biofilm formation and changes in the rates of input load. aqueous sodium sulfide was fed as substrate in the continuous reactor-DOWN. The reactor was operated at a constant temperature of 30 ° C and pH 7, temperature and pH optimum for growth of biomass. The launch of the reactor was made of basalt material. Optimal treatment performance was obtained at a loading rate of 4. 8molS2-m-3h-1 with a conversion efficiency of 100%. The main. . .
