Study on Membrane Fouling of a Hydrogen-Based Membrane Biofilm Reactor Treating Nitrate-Contaminated Drinking Water

Abstract:

A hollow fiber membrane biofilm reactor (MBfR) using Polyethylene (PE) membranes was investigated for denitrification in nitrate-contimanitated drinking water. The reactor was operated over 85 days with influent nitrate loading increasing gradually. The result showed that maximum of nitrate denitrification rate achieved was 3.84 g NO₃ˉ-N/m³/d (1.36 g NO₃ˉ-N/m²/d) and the total nitrogen removal was more than 96%. The results also showed that the membrane pollution was mainly caused by the mineral sedimentation and EPS.
