Book Description
The recent development of less expensive and more efficient ultra-filtration membranes has stimulated a new method of biological waste treatment: membrane bioreactors (MBR). The MBR is a combination of an aeration tank for aerobic biological waste treatment and a membrane unit for physical particulate separation. For wastewater treatment, the MBR process is a modification of the conventional activated sludge process, where a membrane module is used instead of a settling tank to achieve the separation of treated water from the mixed liquor. Wastewater effluent quality is well-monitored for discharge permitting and future regulations will only be more stringent. A treatment system capable of high quality effluent is needed to address future discharge requirements. More recalcitrant compounds such as dyes, pesticides, and other organics are more frequently encountered in treatment processes. Since the ultrafiltration membrane retains these mostly insoluble compounds, their ultimate disposal is controlled and hopefully as less harmful degraded byproducts. The MBR system is capable of effective treatment even for difficult waste streams. In this study, a pilot-scale MBR is operated to investigate the performance of the system in the biodegradation of wastewater containing high molecular weight compounds. Typically, these larger compounds are difficult to treat using conventional methods. Retention of these compounds by the membrane unit improves the chances of microbial degradation. Several solids retention times (SRTs) ranging from 30 days to 2 days will be monitored and the impacts will be evaluated. Biological parameters including microbial diversity, cell viability, and enzymatic activity will be investigated at each SRT. The soluble mixed liquor will be analyzed for several physical/chemical properties throughout the study to evaluate available substrate. Chemical oxygen demand, proteins, and carbohydrates will be analyzed to show the fate of the feed substrates. Effluent quality and treatment efficiency will be studied to assess MBR operation.

Book Description
This research assessed membrane integrity monitoring methods for microfiltration (MF) and ultrafiltration (UF) membrane filtration processes. The project evaluated existing and newly developed methods for integrity monitoring using literature review and full-scale testing of the essential criteria of sensitivity, continuity, identifiably, reliability, and implementability. Recommendations are included. While this research was motivated by the USEPA's LT2ESWTR, the coverage and results have international applicability.

Book Description
The book focuses on Application of Nanotechnology in Membranes for Water Treatment but not only provides a series of innovative solutions for water reclamation through advanced membrane technology but also serves as a medium to promote international cooperation and networking for the development of advanced membrane technology for Universal well-being and to achieve the common goal of supplying economically, environmentally and societally sustainable freshwater and better sanitation systems. This book is unique because the chapters were authored by established researchers all around the globe based on their recent research findings. In addition, this book provides a holistic coverage of membrane development for water treatment, from the membrane preparation and characterizations to the performance for specific processes and applications. Since that water scarcity has become a global risk and one of the most serious challenges for the scientific community in this century, the publication of this book is therefore significant as it will serve as a medium for a good reference of an alternative solution in water reclamation. This book will provide the readers with a thorough understanding of the different available approaches for manufacturing membranes both with innovative polymeric systems and inorganic nano-materials which could give enhanced functionalities, catalytic and antimicrobial activities to improve the performance of the existing membranes. It will be useful for leading decision and policy makers, water sector representatives and administrators, policy makers from the governments, business leaders, business houses in water treatment, and engineers/ scientists from both industrialized and developing countries as well.
