Abstract :
A new material, polyvinyl chloride hollow fibers with single layer have an inner diameter of 0.085 cm, an outer diameter of 0.15 cm and a pore size of 0.01 μm, was used to consisted a hollow fiber membrane biofilm reactor (MBfR). The MBfR was operated to remove nitrate from contaminated groundwater using hydrogen as electron donors. The TN removals of 99% was achieved with the effluent nitrate and nitrite below limit values of drinking water.
