“…Similarly, the sectional resistance model that considers the contribution of uneven cake formation 1 was equally non-suitable to simulate membrane fouling although it was reportedly able to delineate general trends (Li and Wang 2006). Finally, the integration of ASM1-SMP hybrid and resistancein-series (Lee et al 2002), could not be validated and its applicability remains unknown, while the integration of ASM3 and resistance-in-series (Wintgens et al 2003b) was unable to simulate temporal permeability consistently (Geissler et al 2005). …”

Controlled landfilling remains a commonly applied method for municipal solid waste disposal with leachate generation being an inevitable consequence of the decomposition of the waste and the percolation of water through decomposing waste. The membrane bioreactor (MBR) technology has evolved into an effective process in treating such high strength wastewater streams because of its ability to retain high biomass concentration through membrane separation. This paper presents a critical review of the application of the MBR technology for the treatment of leachate and evaluates its performance in this context while highlighting factors affecting MBR operation. The paper concludes with outlining existing gaps and future research needs to improve the understanding and performance of the MBR technology for leachate treatment.

“…Geissler et al [72] set up a model to describe permeability loss of a submerged HF module based on a semi-empirical approach (resistance in series with two fitting parameters) and calibrated this at full scale over three months. Busch et al [86] developed this further to a rigorous model with a www.cet-journal.com high level of detail by including phenomena like concentration polarization, microbial growth in the biofilm, pressure drop in the permeate, etc.…”

Membrane Bioreactors in Waste Water Treatment – Status and Trends

2010

Due to their unique advantages like controlled biomass retention, improved effluent quality, and decreased footprint, membrane bioreactors (MBRs) are being increasingly used in waste water treatment up to a capacity of several 100,000 p.e. This article reviews the current status of MBRs and reports trends in MBR design and operation. Typical operational and design parameters are given as well as guidelines for waste water treatment plant revamping. To further improve the biological performance, specific or hybrid process configurations are shown to lead to, e.g., enhanced nutrient removal. With regards to reducing membrane fouling, optimized modules, advanced control, and strategies like the addition of flux enhancers are currently emerging. IntroductionThe first reported application of membrane bioreactor (MBR) technology in waste water treatment was in 1969, when an ultrafiltration membrane was used to separate activated sludge from the final effluent of a biological waste water treatment system, and the sludge was recycled back into the aeration tank [1]. Due to their unique advantages like superb and hygienic effluent and reduced footprint which has been shown on large scale [2], MBRs, which are combinations of common bioreactors and membrane filtration units for biomass retention, are becoming increasingly popular for waste water treatment. In Europe, the first full-scale MBR plant for treatment of municipal waste water was constructed in Porlock (UK, commissioned in 1998, 3800 p.e.), soon followed by the Büchel and Rödingen WWTPs (Germany, 1999, 1000 and 3000 p.e., respectively), and Perthes-en-Gâtinais WWTP (France, 1999, 4500 p.e.). . Since then, a large number of new results has been published presenting novel process configurations, more insight into the occurring phenomena, and pointing out innovative ways to combat fouling [11,12]. Between 2005 and 2009, the EC funded two major projects on all aspects of MBR technology (AMEDEUS and EUROMBRA), the outcomes of which can be found on www.mbr-network.eu. This paper aims to provide an overview of where MBR technology stands today and which future trends in process configuration and fouling control are emerging. Due to the vast amount of worldwide studies on MBR, this article will not be able to reflect all ongoing developments in the same depth, but will attempt to highlight the main economic and operational trends. Current Status of MBR Market and CapacityThe global market for membrane bioreactor technology is expected to grow at a compound annual growth rate of 10.5 %, increasing in value from $296.0 million in 2008 to $488.0 million by 2013. Growth rates of MBR systems are not the same for all world regions and are not increasing from the same base. Municipal/domestic wastewater treatment was the ear-

“…In the literature to date, a limited number of applications of ANNs have been made to MBRs for modeling of a plant operation [20,21]. Geissler et al [20] used an ANN model to predict the filtration performance in a submerged capillary hollow fiber membrane treating municipal wastewater. Cinar et al [21] have also proposed an ANN model for a submerged MBR treating cheese whey and evaluated its performance at different sludge residence time (SRT).…”

A membrane sequencing batch reactor (MSBR) treating hypersaline oily wastewater was modeled by artificial neural network (ANN). The MSBR operated at different total dissolved solids (TDSs) (35,000; 50,000; 100,000; 150,000; 200,000; 250,000mg/L), various organic loading rates (OLRs) (0.281, 0.563, 1.124, 2.248, and 3.372kg COD/(m(3)day)) and cyclic time (12, 24, and 48h). A feed-forward neural network trained by batch back propagation algorithm was employed to model the MSBR. A set of 193 operational data from the wastewater treatment with the MSBR was used to train the network. The training, validating and testing procedures for the effluent COD, total organic carbon (TOC) and oil and grease (O&G) concentrations were successful and a good correlation was observed between the measured and predicted values. The results showed that at OLR of 2.44kg COD/(m(3)day), TDS of 78,000mg/L and reaction time (RT) of 40h, the average removal rate of COD was 98%. In these conditions, the average effluent COD concentration was less than 100mg/L and met the discharge limits.
