Abstract:
An apparatus for removing organic contaminants from water comprising:an immobilized soil bioreactor (ISBR), the ISBR including a reaction chamber including a top portion, a bottom portion, an aeration side and a non-aeration side, the aeration and non-aeration sides segregated by a supported soil matrix, the supported soil matrix including a microorganism culture adapted for the biodegradation of the organic compounds, the supported soil matrix extending substantially from the bottom portion to the top portion wherein the supported soil matrix allows a circulation of fluid around the supported soil matrix from the aeration side to the non-aeration side; and,a headspace re-circulation system operatively connected to the ISBR for circulating fluid around the supported soil matrix, the headspace re-circulation system including means for pumping gas phase in the top portion of the ISBR to the bottom portion of the ISBR on the aeration side of the ISBR.
