EXPERIMENTAL RESEARCH ON PERMEATE FLUX OF AIRLIFT CERAMIC MEMBRANE-BIOREACTOR

To raise permeate flux of ceramic membrane, reduce industrial specific power consumption, airlift circulation was led into membrane bioreactor under the suction filtration. Experiment was done under airlift condition of nozzle diameter, airlift location, airlift speed, gas nature etc, and comparisonwas carried out with the no airlift condition. Data has proved that the steady permeate flux can rise greatly with airlift circulation. The airlift membrane-bioreactor is potentially applicable in water treatment and bioengineering fields.
