ABSTRACT
BACKGROUND: Hydrogen sulphide (H2S), methyl mercaptan (MM), dimethyl sulphide (DMS) and dimethyl disulphide (DMDS) are the main odorous compounds found in waste gases from wastewater treatment plants. It is known that two-stage biofiltration can be used for improving the removal efficiency of mixture compounds in gas effluent. So the performance of two biotrickling filters, the first one with Acidithiobacillus thiooxidans (BTA), and the second one with Thiobacillus thioparus (BTT) was researched.
