Pesticide Removal by Combined Ozonation and Granular Activated Carbon Filtration

Pesticide Removal by Combined Ozonation and Granular Activated Carbon Filtration PDF Author: Ervin Orlandini
Publisher: Routledge
ISBN: 1351425307
Category : Science
Languages : en
Pages : 184

Book Description
This research aimed to identify and understand mechanisms thar underlie the beneficial effect of ozonation on removal of pesticides and other micropollutants by Granular Activated Carbon (GAC) filtration. This allows optimization of the combination of these two processes, termed Biological Activated Carbon filtration. The study concluded that ozonation significantly improves removal of atrazine by GAC filtration not only due to the wellknown effect of oxidation of atrazine, but also due to the effect of partical oxidation of Background Organic Matter (BOM) present in water. Ozone-induced oxidation of BOM was found to improve adsorption of atrazine in GAC filters. Biodegradation of atrazine in these filters wasnot demonstrated. Higher GAC's adsorption capacity for atrazine and faster atrazine's mass transfer in filters with ozonated rather than non-ozonated influent were explained as due to ozonated BOM. Both can be attributed to enhanced biodegradability and reduced adsorbsbility of partially ozidated BOM compounds, resulting in their increased biodegradation and decreased adsorption in GAC filters.

Activated Carbon

Activated Carbon PDF Author: Zaid K. Chowdhury
Publisher: American Water Works Association
ISBN: 1583219072
Category : Technology & Engineering
Languages : en
Pages : 353

Book Description
"Many books have been written about granular activated carbon. Some focus on the theory of performance and removal mechanisms while others focus on design features. This book focuses on solutions. It describes the challenges facing water providers to provide safe water that is acceptable to their customers, utility experiences using activated carbon, activated carbon applications, and design and procurement approaches. The appendices include detailed case studies and a life-cycle assessment demonstrating favorable sustainability considerations for activated carbon when compared to other treatment technologies. Never before has all of this information been together in one location. The what, why, and how of activated carbon are connected in this book and demonstrate why this treatment technology has maintained its status as an integral treatment technology in the quest for pure water over millennia"--

Taste and Odour in Source and Drinking Water

Taste and Odour in Source and Drinking Water PDF Author: Tsair-Fuh Lin
Publisher: IWA Publishing
ISBN: 1780406657
Category : Science
Languages : en
Pages : 322

Book Description
This book provides an updated evaluation of the characterization and management of taste and odour (T&O) in source and drinking waters. Authored by international experts from the IWA Specialist Group on Off-flavours in the Aquatic Environment, the book represents an important resource that synthesizes current knowledge on the origins, mitigation, and management of aquatic T&O problems. The material provides new knowledge for an increasing widespread degradation of source waters and global demand for high quality potable water. Key topics include early warning, detection and source-tracking, chemical, sensory and molecular diagnosis, treatment options for common odorants and minerals, source management, modelling and risk assessment, and future research directions. Taste and Odour in Source and Drinking Water is directed towards a wide readership of scientists, engineers, technical operators and managers, and presents both practical and theoretical material, including an updated version of the benchmark Drinking Water Taste and Odour Wheel and a new biological wheel to provide a practical and informative tool for the initial diagnosis of the chemical and biological sources of aquatic T&O.

Removal and Degradation of Pharmaceutically Active Compounds in Wastewater Treatment

Removal and Degradation of Pharmaceutically Active Compounds in Wastewater Treatment PDF Author: Sara Rodriguez-Mozaz
Publisher: Springer Nature
ISBN: 3030775097
Category : Science
Languages : en
Pages : 383

Book Description
This book reviews water treatment technologies for the removal of pharmaceutically active compounds (PhACs). It provides the reader with an overview of state-of-the-art techniques and recent efforts to develop more sustainable approaches. After nearly two decades of research into the presence and impact of PhACs in the environment, they remain one of the hottest topics in the fields of environmental chemistry, toxicology and engineering. Accordingly, intensive research efforts are currently being devoted to water treatment technologies that can reduce the presence of these emerging contaminants in water bodies. This book examines various types of contaminated water from industry, hospitals and urban wastewater. It provides the reader with a range of potential solutions for water treatment and reuse, and addresses the advancement of analytical tools for evaluating the performance and efficiency of treatment technologies.
