A novel membrane bioreactor (MBR) with gravity flow was applied to treat domestic sewage and landfill leachate. The variation of permeate flux and its impact factors were studied. The long-term test showed that the average permeate flux of this MBR couldbe 11.2 Lx (m(2) x h)(-1) under the pressure of 8.5 kPa for treating domestic sewage while 6.4 L x (m(2) x h) (-1) and 15.0 kPa, respectively, for landfill leachate. The permeate flux increased with increase of aeration density and decrease of activated sludge concentration when aeration density was less than 400 m(3) x (m(2) x h)(-1). While activated sludge concentration and aeration density had hardly impact on the permeate flux when aeration density was more than 400 m(3) (m(2) xh)(-1). The performances of several different cleaning solutions were tested and the results showed that NaOH-NaClO solution had the best cleaning efficiency. The permeate flux can recovered over 85% of the initial flux. A very high concentration of soluble extracellular polymeric substances (soluble EPS) existed in landfill leachate compared with domestic sewage, which was the main cause leading to a lower permeate flux when treating landfill leachate.
