A novel grille form complex membrane module composed of glass fiber covered with organic membrane and the dynamic membrane bioreactor (DMBR) with this complex membrane were studied. The results showed that the flux of the dynamic membrane of glass fiber tube without covering with organic membrane solution was only 4 L/(m2 x h) at a trans-membrane pressure (TMP) of 0.02 MPa.

Removal of inorganic nitrogen (inorganic-N) from toilet wastewater, using a pilot-scale airlift external circulation membrane bioreactor (AEC-MBR) was studied. The results showed that the use of AEC-MBR with limited addition of alkaline reagents and volumetric loading rates of inorganic-N of 0.19-0.

- A new fiberglass tubular self-forming dynamic membrane bioreactor (DMBR) was tested in a lab for treating landfill leachate, achieving stable performance over 80 days.
- The modified membrane module improved efficiency, allowing for a higher membrane flux of 6 L/(m2 x h) at a lower trans-membrane pressure of 1,450 Pa.
- The system effectively reduced turbidity to below 1.0 NTU and achieved over 71% COD, 96% BOD5, and 98% NH4(+)-N removal, with the dynamic membrane contributing 19.34% of COD removal on its own.
