A biofilm is grown on the gas permeable membrane on the liquid side of the membrane. Teh gas permeable membrane is supported by the structure of the membrane itself. The biofilm is chosen from bacteria to degrade cetain pollutants by means of anaerobic fermentation, aerobic heterotrophic oxidation, dehalogenation, and hydrocarbon oxidation. This is accomplished by means of oxygen and alternate gases (i.e., methane) through the gas permeable membrane to certain bacteria growing on the liquid side of the gas permeable membrane.Field of SearchUtilizing contact surfaces supporting microorganism (e.g., trickling filter, etc.)Including adding ancillary growth medium for microorganism For or with specific microorganism Anaerobically, with subsequently aerobically treating liquid Aerobic treatment And internally circulating the liquid And anaerobic treatment WITH GAS-LIQUID SURFACE CONTACT MEANS With separator Organic Aromatic compound (e.g., PCB, phenol, etc.) | |
