| Abstract | The increasing dependent on biologically treatment to treat toxic and hazardous waste emphasize the need for continuous improvement of treated methods. In this research, the sulfide rich wastewater was treated with Thiobacillus species and designed combination which developed the sulfide oxidation and advantaged of the Airlift for sulfide removal. The purpose of this study focused on the finding of the several parameters effecting to the Airlift reactor tested: Sulfide loading rate, sulfide removal efficiency, % of sulfur production, pH, and Temperature and DO concentration. Airlift could be removed sulfide with areobicacilly at high pH value (7.5-7.8), average temperature 33 °C and short HRT 2.8 hr. Airlift reactor could effetely maintain and increased the removal efficiency, the identical sulfide removal while increased sulfur recovery of the whole process.The morphological examination of the sulfur oxidation bacteria liked worm temperature (Peak 35 °C) but some could alive in the low temperature (About -18°C). Regarding the pilot plant development, the laboratory analysis data was used for reactor volume of Airlift pilot plant for Industry. Then the settler was designed using Laboratory scale settling column test data |
