The MBR market continues to experience a massive growth. The best practice in the field is constantly changing and unique quality requirements and management issues are regularly emerging. The second edition of Membrane Biological Reactors: Theory, Modeling, Design, Management and Applications to Wastewater Reuse comprehensively covers the salient features and emerging issues associated with the MBR technology. The book provides thorough coverage starting from biological aspects and fundamentals of membranes, via modeling and design concepts, to practitioners’ perspective and good application examples.In the second edition, the chapters have been updated to cover the recently emerged issues. Particularly, the book presents the current status of the technology including market drivers/ restraints and development trend. Process fundamentals (both the biological and membrane components) have received in-depth coverage in the new edition. A new chapter has been added to provide a stronger focus on reuse applications in general and the decisive role of MBR in the entire reuse chain. The second edition also comes with a new chapter containing practical design problems to complement the concepts communicated throughout the book. Other distinguishing features of the new edition are coverage of novel developments and hybrid processes for specialised wastewaters, energy efficiency and sustainability of the process, aspects of MBR process automation and recent material on case studies.The new edition is a valuable reference to the academic and professional community and suitable for undergraduate and postgraduate teaching in Environmental Engineering, Chemical Engineering and Biotechnology.

Recent scientific studies have indicated that industrial and pharmaceutical chemicals in our water environment at very low levels may have significant impacts on human and environmental health. Many of these contaminants are not removed using conventional water treatment processes. The use of ultraviolet (UV) light for disinfection of water is becoming increasingly common. The use of UV for photolysis and oxidation holds promise as a clean, effective technology for transforming environmental pollutants of concern.? The goal of this research was to assess, through use of bioassays and chemical analyses, the degradation, by-product formation, and subsequent toxicity of endocrine disrupting contaminants (EDCs) following UV and UV/H2O2 oxidation treatment of water. Known EDCs were investigated for treatability and subsequent formation of estrogenic by-products over a range of UV operating points. Evaluations of treatment were made by analytical chemistry and by assessing changes in estrogenic activity utilizing both in vitro and in vivo based assays. UV light alone either from LP or MP sources at low or high UV fluences will not be effective for degradation of the estrogenic chemicals studied, therefore, utilities should not expect any effects on estrogenic contaminants under UV disinfection conditions. For effective treatment of the EDCs studied, and likely others, UV can be used in combination with low levels of hydrogen peroxide to achieve advanced oxidation conditions for destroying parent compounds and residual estrogenic activity.? The use of an estrogen screening assay should complement any chemical analysis when studying treatment processes that result in transformation of an estrogenic parent contaminant to its known or unknown breakdown products. These assays can monitor residual estrogenic activity of any by-products, monitor estrogenic activity for mixtures of pollutants, and provide an end point marker, indicating effective treatment levels. ? ?

Various environmental issues are related to urban activities. Through the growing recognition of the necessity to develop sustainable urban mana- ment, the University of Tokyo established the Center for Sustainable Urban Regeneration (cSUR) in July 2003. A research program at the cSUR was designed to create an integrated approach and to provide knowledge for s- tainable urban regeneration with the aid of a global network of researchers and professionals, and to coordinate the international research alliance made up of leading academic institutions worldwide. As part of the program, several studies have been conducted focusing on urban environmental problems in Asian megacities such as Tokyo, Taipei, Guangzhou, Shenzhen, and Bangkok. The following topics in particular were selected for integrated and strategic research supported by researchers from the fields of architecture, civil engineering, and environmental engineering: –Integrated analysis of the urban atmospheric environment and its re- tionship with control of indoor air conditions in East and Southeast Asian countries –Dynamic behavior of urban non-point pollutants in coastal envir- ments The research contains interesting intensive field-monitoring data on the coastal environment and the urban air environment. Topics also include state-of-the-art environmental monitoring and simulation analysis in urban areas. Key aspects of the research in advanced monitoring and the appli- tion of environmental numerical simulation were selected for inclusion in this book. Integrating the monitoring and modeling of urban environments is essential for engineers to identify and investigate environmental problems and their solutions.
