Abstract—The objective of this work was to evaluate the
effectiveness of integrated biological conventional treatment
with membrane bioreactor (MBR) system in removing organic
and nutrients from dairy industry wastewater. A pilot
treatment system including biological treatment and submerged
MBR system was installed at Kuwait Institute for Scientific
Research (KISR) research plant. The integrated MBR system
was operated at the following conditions: average influent flow
rate of 1 m3/d, average sludge retention time (SRT) of 38 d, and
average hydraulic retention time (HRT) of 2 h. The results
clearly show the performance of the integrated system in
removing organic matters with an average removal efficiency of
99% for both biological oxygen demand (BOD) and chemical
oxygen demand (COD). However, good reduction in nutrients
concentration in the system effluent. The average reported
efficiencies on total nitrogen (TN), ammonium (NH4-N) and
total phosphorus (TP) were 45, 44.8 and 67.1%, respectively.
Index Terms—Dairy, industrial wastewater, membrane, removal efficiency.
