ABSTRACT
The search for unknown micro-organisms can also open up interesting possibilities for new biological wastegas treatment applications. In biological wastegas treatment systems treating reduced sulfur compounds like hydrogen sulfide and carbon disulfide, sulfuric acid is the final product at complete conversion. This acidic water leaves the biological wastegas treatment system when it is operated without the additional of pH neutralizing chemical such as caustic. When possible, this operation without the addition of chemicals is preferred as caustic can be relatively expensive and adds to operational concerns as it requires safety measures for proper feeding and storage.
