Book Description
This book describes a simplified approach to the modelling and process design of a fixed bed hybrid bioreactor for wastewater treatment. In this work a simplified model for hybrid bioreactor is developed to determine output parameters like exiting substrate concentration in bulk liquid, average substrate flux in the biofilm, effective and total biofilm thickness. The model is based on mass balance of both carbonaceous substrate and biomass under suspended and attached growth simultaneously along with substrate mass transport into the biofilm. The proposed model has also been validated with the results obtained from experimental study with municipal wastewater considering as a low strength wastewater with no inhibition. There is a flexibility of the proposed model making it a versatile one to find out the exiting substrate concentration both in hybrid bioreactor as well as in a completely mixed biofilm reactor (CMBR). The book caters to academics and practitioners working in the field of advanced wastewater treatment.

Book Description
This book deals with those processes that use semipermeable membranes to enhance or enable the biological treatment of wastewater. In this context biological treatment could involve aerobic or anaerobic processing with suspended and supported biomass, or biofilms. Membrane bioreactors for wastewater treatment are in a period of rapid development. Installations are growing at about 15% per annum. In addition to process evolution driven by industry there is a high level of research activity in academia and research organizations. Although there is a recent book (Judd, The MBR Book, Elsevier, 2006) comprehensively devoted to MBRs it can be anticipated that within the next 2 or 3 years there will be significant advances in understanding, operation and systems design to warrant a new book. In addition, the MBR Book (2006) has a bias towards the potential MBR practitioner and less reference to research and development issues. This new book will provide an update on the status of MBRs and report on cutting edge developments and fundamental insights that will enhance the application of the technology. The MBR is now part of the main stream or wastewater treatment. However the technology continues to develop rapidly and is the focus of intensive global research. This book provides a status report on MBR technology and provides details of cutting edge research and developments that are leading to enhanced MBR processes. Both academic researchers and industrial innovators have contributed their latest knowledge. Topics covered include the MBR status report, filtration systems performance (module design, hydrodynamics, energy), process configuration and design options, fouling and cleaning, effluent water quality and MBR modelling. The emphasis is on aerobic MBRs but recent developments in anaerobic MBRs and novel MBR concepts , such as biofilm MBRs and microbial fuel cells are described.

Book Description
An enormous amount of synthetic dyes is used annually in the textile, leather, plastics, paper, and dye industries due to their coloring properties. Although dyes give color to materials, they are prone to increase the level of pollution in the environment. The colored wastewater produced in industrial sectors is released into water bodies, posing threats to the ecosystem. To reduce the adverse effects of dyes in the environment, it is necessary to implement feasible and cost-effective strategies. '"Dye Biodegradation Mechanisms and Techniques - Recent Advances'' provides fundamental principles and pathways of bio-based mechanisms in dye removal. This edition firstly discusses dye classification and pollution, then concentrates on the application of fungi, mesophilic bacteria, microflora, and enzymes in dye degradation. This book also highlights the performance of sequential batch reactor systems, moving bed biofilm reactors, and hybrid bioreactors for dye biodegradation

Book Description
Many industrial processes use water as a solvent and therefore produce wastewater containing chemicals from that process. The amounts of these chemicals and the types will vary hugely depending on the industry and the processes running and may include things that are hazardous to health or the environment. This makes the treatment of industrial wastewater both extremely important and highly complex. One route for industrial wastewater treatment is the use of bioreactors. Biological Treatment of Industrial Wastewater presents a comprehensive overview of the latest advances and trends in the use of bioreactors for treating industrial wastewater. Several different types of bioreactor and their applications are discussed, alongside trends and considerations important in designing bioreactors. Bringing together a wealth of different approaches and voices this book will be a useful resource for anyone working in water treatment or looking at how industrial processes can be made more environmentally friendly.

Book Description
The most commonly used biological wastewater treatment technologies still have serious technical-economical and sustainability-related limitations, due to their high energy requirements, poor effluent quality, and lack of energy and resource recovery processes. In this thesis, novel electrochemical membrane bioreactors (EMBRs), which take advantage of membrane separation and bioelectrochemical techniques, are developed for wastewater treatment and the simultaneous recovery of energy and resources. Above all, this innovative system holds great promise for the efficient wastewater treatment and energy recovery. It can potentially recover net energy from wastewater while at the same time harvesting high-quality effluent. The book also provides a proof-of-concept study showing that electrochemical control might offer a promising in-situ means of suppressing membrane fouling. Lastly, by integrating electrodialysis into EMBRs, phosphate separation and recovery are achieved. Hence, these new EMBR techniques provide viable alternatives for sustainable wastewater treatment and resource recovery.
