“…This process can achieve high N-removal by simultaneous denitrification within the biofilm [28]. In addition, less biomass is suspended and the circulating media generate some scrubbing action which both improve filterability [30,31] despite the fact that the attached biomass has a much higher fouling potential than suspended activated sludge [32].…”

Membrane Bioreactors in Waste Water Treatment – Status and Trends

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-

“…Tertiary treatment normally includes media filtration followed by carbon adsorption and sometimes physico-chemical treatment [10]. Advance treatment processes for tannery effluent treatment include advance oxidation processes such as Fenton, H 2 O 2 /UV, electrochemical oxidation, and electro-Fenton oxidation and membrane bio-reactors and membrane separation processes [2,[10][11][12][13][14][15][16][17].…”

“…Biotrickling filters have less operating and capital constraints, less relation time/high volume through put and capability to treat acid degradation product of VOCs (Cox and Deshusses, 1998). In membrane bioreactors there are no moving parts, process scale up is more easy and flow of gas and liquid can be varied independently, without the problems of flooding, loading or foaming (Artiga et al, 2005). Bioscrubbers need relatively smaller space requirements and able to deal with high flow rates and severe fluctuations.…”

Volatile Organic Compounds (VOCs) are among the most toxic chemicals which are detrimental to humans and environment. There is a significant need of fully satisfactory method for removal of VOCs. There are several methods including physical, chemical and biological treatments available to remove VOCs by either recovery or destruction. The aim of the present study is to summarize the available methods for VOC removal; trying to find a promising method among the available techniques. A wide range of VOCs can be treated biologically in which it offers advantages over more traditional processes including lower operating and capital costs and a smaller carbon footprint. However, due to a complex nature and diversity of VOCs it is hard to find a simple and promising method. Treatment still requires more research to solve the associate problems with available VOC elimination techniques.
