Wastewater Reuse: Removal Of Emerging Trace Organic Contaminants (Troc), Faisal Hai, Long Nghiem, Stuart Khan, William Price, Kazuo Yamamoto

This chapter reviews current and new technologies for the removal of emerging TrOC from wastewater for reuse purposes. In particular, it compares the relative performance of Membrane bioreactors (MBR) with other conventional biological processes. It is shown that MBR has many intrinsic advantages over other methods leading to superior performance. Fundamental to this is the presence of a membrane barrier which provides a range of other adsorption mechanisms for TrOC. However, in practice there are many factors affecting TrOC removal by MBR, leading to sometimes conflicting reports in the literature from both lab scale studies as well as full scale …

The aim of this study was to demonstrate the complementarity of combining membrane bioreactor (MBR) treatment with UV oxidation or high pressure membrane filtration processes such as nanofiltration (NF) or reverse osmosis (RO) for the removal of trace organic contaminants (TrOC). The results suggest that the removal mechanisms of TrOC by either UV oxidation or NF/RO membrane filtration differ significantly from those of an MBR system. Thus, they can complement MBR treatment very well to significantly improve the removal of TrOC. MBR treatment can effectively remove hydrophobic and readily biodegradable hydrophilic TrOC. The remaining hydrophilic and biologically persistent TrOC were …

The potential fields of application of biocatalytic membrane reactors have widened considerably in recent years. Although biocatalytic membrane reactors, in general, are yet to achieve broad industrial application, in the not too far future they are expected to play a major role, not only for the production, transformation and valorization of raw materials but also for environmental remediations. This chapter comprehensively reviews the laboratory scale studies which demonstrate the potential of biocatalytic membrane reactors in wastewater treatment applications. Studies reponed in the literature, however, serve as proof of concept only. Issues that need to be addressed in order to achieve …
Scenarios For Peer-To-Peer Learning In Construction With Emerging Forms Of Collaborative Computing, Teemu Leinonen, Jukka Purrna, Kiarii Ngua, Alexander Hayes
Scenarios For Peer-To-Peer Learning In Construction With Emerging Forms Of Collaborative Computing, Teemu Leinonen, Jukka Purrna, Kiarii Ngua, Alexander Hayes
Alexander Hayes Mr.
Many small and medium enterprises (SMEs) in Europe are interested in finding new methods of training and workplace learning. Technology-enhanced practices of peer-to-peer learning may offer various new possibilities for SMEs. In this study we consider emerging technologies for informal learning in construction work. These technologies include wearable computing, invisible and ambient computing, augmented reality and novel interaction technologies. Three preliminary scenarios presented in this paper demonstrate how these technologies may be used. These scenarios have been developed, with a focus on the use of technology within a community supporting peer-to-peer learning, that may negate some of the social concerns …
