MEMBRANE BIOREACTOR

摘要

A membrane bioreactor which provides close contact between microbial cells and a gas by culturing microbial cells on the outside of a membrane through which a culture medium can flow and passing the gas through a support matrix surrounding the membrane. The cells are too big to pass through the membrane and so are trapped on its surface in close contact with both gas and liquid. This enables high oxygen transport rates, a superior environment for growth and thus a saving in power consumption.
