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
Membrane integrity is in an interesting combination of science, engineering, and regulations. The book introduces the reader to the subject in the context of drinking water filtration. Both theoretical and practical aspects of membrane integrity testing are discussed along with historical and future technologies. Discussed are the types and causes of integrity breaches, tests to perform to discover them, how to establish a membrane integrity testing program and government disinfection regulations.

Book Description
This book provides information and tools to assist operators in evaluating treatment plant operational changes (such as the changes in treatment efficiency due to changes in the raw water). and to help operators make corresponding water chemistry or other process changes to keep the plant operating properly. Both operators and system managers can use the analysis tools to more easily understand and operate a plant and be able to identify and correct any plant deficiencies.

Book Description
High-pressure (HP) membranes, reverse osmosis, and nanofiltration are used increasingly to treat brackish and organic laden surface waters as water purveyors are forced to utilize lower quality source waters to meet potable water demands. In addition, reverse osmosis has become an integral part of the advanced reclamation process for the indirect potable reuse of domestic wastewaters. In these applications, HP membranes are expected to serve as a positive barrier to pathogens. To date, integrity methods for full-scale HP membrane systems have been limited to conductivity and total organic carbon monitoring, approaches that can only assess pathogen removals to two logs (99%). The first objective of this research was to determine the integrity of RO and NF membrane systems with respect to viral passage using both particulate (MS2 viruses and fluorescent microspheres) and soluble (Rhodamine WT) surrogates. The second objective was to compare the capability of these surrogates for use in assessing integrity of intact and compromised RO and NF membranes when evaluated in a number of configurations.

Book Description
This study increases our current understanding on the degradation/ageing mechanisms occurring on porous membranes used in the water and wastewater industries. Accelerated membrane degradation was obtained through both static and consecutive ageing protocols on the pilot-scale, and a range of carefully selected characterisation and analytical techniques was used to characterise the nascent changes faced by the membrane material. The report covers four interrelated sections: Critical assessment of characterisation techniques Static accelerated ageing Consecutive accelerated ageing Consecutive ageing of industrially-aged membranes. This final report summarises the aims, objectives, outcomes and limitations of the individual work packages, along with some recommendations for future work. This book is co-published with Water Research Australia.

Book Description
This is a comprehensive guide to single-stranded RNA phages (family Leviviridae), first discovered in 1961. These phages played a unique role in early studies of molecular biology, the genetic code, translation, replication, suppression of mutations. Special attention is devoted to modern applications of the RNA phages and their products in nanotechnology, vaccinology, gene discovery, evolutionary and environmental studies. Included is an overview of the generation of novel vaccines, gene therapy vectors, drug delivery, and diagnostic tools exploring the role of RNA phage-derived products in the revolutionary progress of the protein tethering and bioimaging protocols. Key Features Presents the first full guide to single-stranded RNA phages Reviews the history of molecular biology summarizing the role RNA phages in the development of the life sciences Demonstrates how RNA phage-derived products have resulted in nanotechnological applications Presents an up-to-date account of the role played by RNA phages in evolutionary and environmental studies

Book Description
This is the third volume of the five-volume book series “Engineering Tools for Environmental Risk Management”. The book series deals with the following topics: • Environmental deterioration and pollution, management of environmental problems • Environmental toxicology – a tool for managing chemical substances and contaminated environment • Assessment and monitoring tools, risk assessment • Risk reduction measures and technologies • Case studies for demonstration of the application of engineering tools The authors aim to describe interactions and options in risk management by providing a broad scientific overview of the environment, its human uses and the associated local, regional and global environmental problems; interpreting the holistic approach used in solving environmental protection issues; striking a balance between nature’s needs and engineering capabilities; understanding interactions between regulation, management and engineering; obtaining information about novel technologies and innovative engineering tools. This third volume provides an overview on the basic principles, concepts, practices and tools of environmental monitoring and contaminated site assessment. The volume focuses on those engineering tools that enable integrated site assessment and decision making and ensure an efficient control of the environment. Some topics supporting sustainable land use and efficient environmental management are listed below: • Efficient management and regulation of contaminated land and the environment; • Early warning and environmental monitoring; • Assessment of contaminated land: the best practices; • Environmental sampling; • Risk characterization and contaminated matrix assessment; • Integrated application of physical, chemical, biological, ecological and (eco) toxicological characterization methods; • Direct toxicity assessment (DTA) and decision making; • Online analyzers, electrodes and biosensors for assessment and monitoring of waters.; • In situ and real-time measurement tools for soil and contaminated sites; • Rapid on-site methods and contaminant and toxicity assessment kits; • Engineering tools from omics technologies, microsensors to heavy machinery; • Dynamic characterization of subsurface soil and groundwater using membrane interface probes, optical and X-ray fl uorescence and ELCAD wastewater characterization; • Geochemical modeling: methods and applications; • Environmental assessment using cyclodextrins. This book series focuses on the state of knowledge about the environment and its conscious and structured application in environmental engineering, management and decision making.
