ABSTRACT:
A microbubble generator is disclosed for optimizing the rate and amount of xygen transfer to microbial inocula or biocatalysts in bioreactor systems. The microbubble generator, and an associated immobilized cell reactor, are useful in the detoxification and cleanup of non-volatile polymeric and volatile organic-contaminated aqueous streams. In particular, they are useful in the continuous mineralization and biodegradation of toxic organic compounds, including volatile organic compounds, associated with industrial and municipal effluents, emissions, and ground water and other aqueous discharges. One embodiment of the invention includes a microbubble chamber packed with small inert particles through which a liquid effluent and oxygen or another gas are admitted under pressure, followed by a venturi chamber to further reduce the size of bubbles.
