Abstract :
The evaluation of a membrane bioreactor (MBR) for pretreatment of reverse osmosis (RO) in order to reuse and
reclamation of industrial town wastewater treatment plant was investigated in this study. Performance of MBR
effluent through water quality in term of parameters such as chemical oxygen demand (COD), total suspended
solids (TSS), total nitrogen (TN) and total coliform (TC) were measured. Also Silt density index (SDI) was used as
indicator for RO feed water. The results of this study demonstrated that MBR produce a high quality permeate
water. Approximately 75%, 98%, 74% and 99.9% removal of COD, TSS, TN and TC were recorded, respectively. Also
SDI of the permeate effluent from membrane was below 3 for most of the times. It means that pilot yield a high
quality treated effluent from the membrane module which can be used as RO feed water.
