    Abstract: A new hydrogen-based hollow fiber membrane biofilm reactor (MBfR) using CO2 for pH control and as carbon source was developed in this work. Systematic research was conducted to investigate the MBfR performance including effluent nitrate, pH and Langelier Saturation Index (LSI) under different CO2 pressure. A mathematical model was built up to predict optimal CO2 pressure before the project was carried out. Long-term performance of the new MBfR was also evaluated. When CO2 was delivered at 0.05 MPa, 99% nitrate was removed with a constant neutral pH in the reactor.
