International Journal of Environment and Pollution (IJEP), Vol. 38, No. 3, 2009

Abstract: The operational performance of a submerged hollow fibre Membrane Bio-Reactor (MBR) for treatment of municipal wastewater on pilot scale was investigated. The experimental results indicated that the removal efficiency for SS, COD, NH₄-N, turbidity, bacterium, iron (Fe²⁺) and Manganese (Mn²⁺) was 100%, 94.5%, 98.3%, 99.7%, lg6, 99%, 92.3%, respectively. The water quality of the effluent was quite good. The reclaimed water could be reused either directly or indirectly for municipal or industrial purposes. The MBR had a strong ability to resist loading shock and DO was a crucial factor to membrane fouling.
