Book excerpt: New USEPA regulations require changes to water treatment that can accelerate infrastructure degradation. One recent regulation of particular concern in this regard is the Enhanced Coagulation Rule, which requires improved removal of Total Organic Carbon (TOC) from water supplies. One of the most common means of improving TOC removal is to enhance existing coagulation treatment processes by reducing coagulation pH or using higher coagulant doses. There is substantial concern that the lowered coagulation pHs and higher coagulant doses will significantly accelerate degradation of infrastructure. The goal of this research was to concisely describe what is known about accelerated degradation of infrastructure from conditions brought about during enhanced coagulation. It was anticipated that such an effort would allow utilities to decrease damage by learning from the experiences of others, reviewing of the literature, and executing some new experiments. Originally published by AwwaRF for its subscribers in 2004.

Available in PDF, EPUB and Kindle. Book excerpt: This manual is a source document for utilities that are considering a coagulant changeover. It is intended to provide an appreciation of what must be considered for a successful changeover based on the input of U.S. and Canadian utilities (Chapters 1 and 6). New regulatory requirements will likely have the broadest and most substantial impact on primary coagulant use (Chapter 3). The Interim Enhanced Surface Water Treatment Rule (IESWTR) and Stage 1 Disinfectant and Disinfection Byproducts Rule (Stage 1 DBPR) will make finished water requirements more stringent to address microbial removal and the impacts of disinfection. Enhanced Coagulation and/or other operational and treatment practices will be used to achieve these requirements. The science of coagulation (Chapter 4) requires a special focus to address the intricacies of coagulation chemistry. The manual provides a step-by-step methodology to conduct a coagulant changeover using a detailed protocol (Chapter 5) -- background, executive summary.

Available in PDF, EPUB and Kindle. Book excerpt: Over the last few years there has been a growing concern over the increasing concentration of micropollutants originating from a great variety of sources including pharmaceutical, chemical engineering and personal care product industries in rivers, lakes, soil and groundwater. As most of the micropollutants are polar and persistent compounds, they are only partially or not at all removed from wastewater and thus can enter the environment posing a great risk to the biota. It is hypothesized that wastewater is one of the most important point sources for micropollutants. Treatment of Micropollutants in Water and Wastewater gives a comprehensive overview of modern analytical methods and will summarize novel single and hybrid methods to remove continuously emerging contaminants - micropollutants from the aqueous phase. New trends (e.g. sensor technology, nanotechnology and hybrid treatment technologies) are described in detail. The book is very timely because the new techniques are still in the development phase and have to be realized not only in the laboratory but also on a larger scale. The content of the book is divided into chapters that present current descriptive and analytical methods that are available to detect and measure micropollutants together with detailed information on various chemical, biological and physicochemical methods that have evolved over the last few decades. Treatment of Micropollutants in Water and Wastewater will also enable readers to make well informed choices through providing an understanding of why and how micropollutants must be removed from water sources, and what are the most appropriate and available techniques for providing a cost and technologically effective and sustainable solutions for reaching the goal of micropollutant-free water and wastewater. The book will be suitable for water and wastewater professionals as well for students and researchers in civil engineering, environmental engineering and process engineering fields.

This book was released on 2010 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Treatment facilities out of compliance with EPA regulations are often not using optimal chemical treatment. Determination of the most effective chemical type, combination and concentration can aid in reduction of disinfection by-product precursors. The effects of optimal chemical treatment using enhanced coagulation and enhanced softening was tested on three surface waters (two reservoirs and one lake sources), and one ground water (alluvial wells). Results indicated enhanced coagulation was more effective at removing DBP precursors from waters with higher initial UV-254 absorbance values and lower alkalinities while enhanced softening was more effective for waters with lower initial UV-254 absorbance values and higher alkalinities. In a number of cases, ferric salts outperformed aluminum salts at reducing the DBP formation potential. Redox potential measurements were added to the list of analyses to determine trends and the feasibility of using this parameter as an additional indicator of process efficiency. It is expected that Eh will trend as the inverse of pH. However, this research presents that under constant pH conditions, the Eh readings seem to indicate the destabilization and stabilization processes expected during the coagulation step in drinking water treatment. Comparison of the Eh readings from the start of various treatment stages to the end provides some indication of the effectiveness the enhanced coagulation or enhanced softening process has on the removal of organic precursors for disinfection by-products.

Available in PDF, EPUB and Kindle. Book excerpt: For decades an increasingly rapid urbanization pace, modern industrial development, and constantly intensive agricultural practices have caused controlled or uncontrolled release of hazardous contaminants that seriously threaten our environment. All natural spheres (atmosphere, hydrosphere, biosphere, lithosphere, and anthroposphere) seem to have been exposed to harmful practices and emerging research in nanomaterials is now trying to combat their adverse impact on physical ecosystems and organisms, as well as human health. In this context, pollution remediation at the nanoscale has come to the forefront for its potential to unlock sustainable, highly efficient, and cost-effective technologies, capable to restore in situ or ex situ land, water, and air resources. Nanotechnology to Monitor, Remedy, and Prevent Pollution covers design, fabrication, and extensive applications of engineered nanostructured materials in various shapes and morphologies (such as nanoparticles, wires, tubes, fibres) that, because of their size, surface-to-volume ratio, and high reactivity, function as catalysts and adsorbents of organic pollutants (aliphatic and aromatic hydrocarbons), gases, chemicals (arsenic, manganese, iron, nitrate, heavy metals), antibiotics, and biological entities (bacteria, viruses, parasites). Their integration with biotechnological processes for monitoring and prevention of pollution is also explored alongside the invisible dangers caused by noise. This is a valuable book for academics, researchers, undergraduate and postgraduate students working on environmental engineering for sustainability, environmental sciences, biotechnology, and nanotechnology.? Comprehensively presents applications of state-of-the-art nanotechnologies and nanomaterials for control, prevention, and removal of persistent air, water, and soil pollutants. Provides a new benchmark for pros and cons of established processes for nano remediation, revealing the importance of such research beyond national boundaries and policies. Classifies noise as a contaminant and discusses how its real impacts on human and animal life can be limited through impedance-matching nanotechnology.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The T.E Maxson Wastewater Treatment Plant (WWTP) located in Memphis, TN is designed to treat 90 million gallons per day (mgd) of municipal and industrial wastewater daily. Bar screens, Primary Clarifiers, Biotowers, Activated sludge and secondary clarifiers are main treatment units.Biotowers are one of major sources of odorous emissions usually under anaerobic condition. In other words, removing more colloidal and suspended organics in primary clarifiers can improve biotowers performance ans decrease malodorous conditions in biotowers. Chemically enhanced primary treatment (CEPT) is using chemical treatment in primary clarifiers to promote particulate contaminant removal. The main goal of this research was to study contaminant removal efficiency of different coagulants, polymers and their blends on influent wastewater of Maxson WWTP. In this regard, the effect of alum, ferric sulfate, aluminum chlorohydrate(ACH), polydiallyldimethylammonium(polyDADMAC), polyamine and ACH-polyamine, and ACH-polyDADMAC were examined in terms of enhancing removal of TSS, COD, TKN, BOD5, soluble BOD5, total phosphorus, and pH.

Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive Water Quality and Purification, Four Volume Set provides a rich source of methods for analyzing water to assure its safety from natural and deliberate contaminants, including those that are added because of carelessness of human endeavors. Human development has great impact on water quality, and new contaminants are emerging every day. The issues of sampling for water analysis, regulatory considerations, and forensics in water quality and purity investigations are covered in detail. Microbial as well as chemical contaminations from inorganic compounds, radionuclides, volatile and semivolatile compounds, disinfectants, herbicides, and pharmaceuticals, including endocrine disruptors, are treated extensively. Researchers must be aware of all sources of contamination and know how to prescribe techniques for removing them from our water supply. Unlike other works published to date that concentrate on issues of water supply, water resource management, hydrology, and water use by industry, this work is more tightly focused on the monitoring and improvement of the quality of existing water supplies and the recovery of wastewater via new and standard separation techniques Using analytical chemistry methods, offers remediation advice on pollutants and contaminants in addition to providing the critical identification perspective The players in the global boom of water purification are numerous and varied. Having worked extensively in academia and industry, the Editor-in-Chief has been careful about constructing a work for a shared audience and cause
