The SepaTech Micro-bubble System has been applied to bio-argumentation by introducing an ERP KB-12 strain into contaminated soil with volatile organic compounds such as benzene. The ERP KB-12 strain can decompose benzene under aerobic conditions and effectively reduce the odor derived from contaminants in a short time. As a result of bio-argumentation at the old site of N company's Kobe factory in Chuo-ku, Kobe, we succeeded in improving the odor by injecting a relatively small amount of the ERP KB-12 strain. The odor before implementing bio-argumentation recorded about 960 on average in some plots, but it was irreversibly reduced to almost 0 about 24 hours after injection. By combining the ERP KB-12 strain and SepaTech Micro-bubble System, it is possible to effectively purify volatile organic compounds such as benzene in situ.
