Abstract

An apparatus and method for the treatment of contaminated water by biodegradation is provided. In particular, the apparatus and method are suited for the biodegradation of volatile organic compounds (VOC's) such as trichloroethylene and related compounds or benzene and related compounds. The process employs an immobilized soil bioreactor (ISBR) having a headspace re-circulation system.
