This research report evaluates the fouling and flux decline performance of membranes after the source water is pretreated with coagulation, and identifies the conditions under which coagulation can improve membrane performance as well as the mechanisms that cause natural waters to foul membranes. Conducted at the University of Illinois, the experiments involved collecting raw water from lakes and rivers, coagulating the water in the laboratory, characterizing the physical and chemical composition of the water before and after coagulation, measuring flux decline as the water was filtered through MF and UF membranes, and examining the fouled membranes with scanning electron microscopy.

Coagulation and Flocculation in Water and Wastewater Treatment provides a comprehensive account of coagulation and flocculation techniques and technologies in a single volume covering theoretical principles to practical applications. Thoroughly revised and updated since the 1st Edition it has been progressively modified and increased in scope to cater for the requirements of practitioners involved with water and wastewater treatment. A thorough gamut of treatment scenarios is attempted, including turbidity, color and organics removal, including the technical aspects of enhanced coagulation. The effects of temperature and ionic content are described as well as the removal of specific substances such as arsenic and phosphorus. Chemical phosphorus removal is dealt with in detail, Rapid mixing for efficient coagulant utilization, and flocculation are dealt with in specific chapters. Water treatment plant waste sludge disposal is dealt with in considerable detail, in an Appendix devoted to this subject. Invaluble for water scientists, engineers and students of this field, Coagulation and Flocculation in Water and Wastewater Treatment is a convenient reference handbook in the form of numerous examples and appended information.
Pretreatment for Reverse Osmosis Desalination is a comprehensive reference on all existing and emerging seawater pretreatment technologies used for desalination. The book focuses on reverse osmosis membrane desalination, which at present is the most widely applied technology for the production of fresh drinking water from highly saline water sources (brackish water and seawater). Each chapter contains examples illustrating various pretreatment technologies and their practical implementation. - Provides in-depth overview of the key theoretical concepts associated with desalination pre-treatment - Gives insight into the latest trends in membrane separation technology - Incorporates analytical methods and guidelines for monitoring pretreatment systems
This book provides a critical, carefully researched, up-to-date summary of membranes for membrane bioreactors. It presents a comprehensive and self-contained outline of the fundamentals of membrane bioreactors, especially their relevance as an advanced water treatment technology. This outline helps to bring the technology to the readers’ attention, and positions the critical topic of membrane fouling as one of the key impediments to its more widescale adoption. The target readership includes researchers and industrial practitioners with an interest in membrane bioreactors.

Approximately 77 percent of the freshwater used in the United States comes from surface-water sources and is subject to natural organic matter contamination according to the United States Geological Survey. This presents a distinct challenge to water treatment engineers. An essential resource to the latest breakthroughs in the characterization, treatment and removal of natural organic matter (NOM) from drinking water, Natural Organic Matter in Waters: Characterization and Treatment Methods focuses on advance filtration and treatment options, and processes for reducing disinfection byproducts. Based on the author's years of research and field experience, this book begins with the characterization of NOM including: general parameters, isolation and concentration, fractionation, composition and structural analysis and biological testing. This is followed by removal methods such as inorganic coagulants, polyelectrolytes and composite coagulants. Electrochemical and membranes removal methods such as: electrocoagulation, electrochemical oxidation, microfiltration and ultrafiltration, nanofiltration and membrane fouling. - Covers conventional as well as advanced NOM removal methods - Includes characterization methods of NOM - Explains removal methods such as: removal by coagulation, electrochemical, advanced oxidation, and integrated methods
Treating potable and polluted water for the world's population is still one of our most important challenges. The United Nations estimate that more than 1.2 billion people suffer from inadequate water supply and an even larger number, up to 4 billion people, are without hygienic disposal of waste and wastewater. Water technology and the necessary "know-how transfer", has been the key objective of the Gothenburg symposia from the very beginning. The contents of this book respond to these challenges and demonstrate the impressive development of the field of chemical waster and wastewater treatment. The Chemical Water and Wastewater Treatment Series provides authoritative coverage of the key current developments in the chemical treatment of water and wastewater in theory or practice and related problems such a s sludge production and properties, and the reuse of chemicals and chemically-treated waters and sludges. For the tenth in the series, the contributions document the development if the field of chemical water and wastewater technology, both in terms of new technological developments as well as public and administrative acceptance and approval of the solutions offered. Such new developments include the use of membrane technology, the application of computational tools for kinetic process modelling and optimisation as well as the use of advanced oxidation processes in actual water treatment. Chemical Water and Wastewater Treatment VII covers fundamental science, new technological developments and practical experience and is an invaluable reference source for engineers scientists and administrators, active in the treatment of drinking water, municipal and industrial wastewater and sludges.
