Abstract:

The use of membrane bioreaetor (MBR) has been an increasing issue in replacing the conventional water and wastewater treatment processes to produce high quality treated water. In MBR systems design,the submergedmembranebioreactor (SMBR)can assist in significantlyreducingpower consumptionas the entire treatment activity (such as adsorption/biodegradation,liquid-solid separation, andsludgeaccumulationandwithdrawal)canbe carriedout in a singleunit. In this study, the performance of conventional 5MBR and non-eonventional submerged membrane adsorption bioreactor (SMABR) was evaluated in terms of organic and bacterial removal efficiencies,biomassgrowthvia specificoxygen uptake rate (SOUR) and mixed liquor suspendedsolids (MLSS), and membrane fouling through the development of transmembrane pressure (TMP) and sustainableflux.Theresults indicatethat both ofSMBRand5MBARproducedvery high effiuentquality. However,SMABRappeared to have a better performance as it achieved nearly 100%ofTOC andCOD removalswhile having lowerTMPdevelopment and higher SOUR,The MLSSkept constant (around 10 gIL) after 10 days operation in 5MBAR compared to about 4 gILofMLSS in 5MBR case. In order 10 enhancethe sustainableflux, an idea ofadding a predeterminedamountof spongeinto 5MBRreactor was proposedand tested, The results show that 10% of volume fraction of sponge addition could increase 2 folds of sustainablefluxofSMBRsystemat an air flow rate of9 L/min.
