Mineral scale deposits, corrosion, suspended matter, and microbiological growth are factors that must be controlled in industrial water systems. Research on understanding the mechanisms of these problems has attracted considerable attention in the past three decades as has progress concerning water treatment additives to ameliorate these concerns. The Science and Technology of Industrial Water Treatment provides a comprehensive discussion on the topic from specialists in industry and academia. The book begins with an overview of water chemistry and covers the characteristics of commonly encountered mineral scales. It addresses the formation and control of different scales in various systems and examines new developments in membrane-based separation processes. Next, it provides a detailed account on the operational challenges of reverse osmosis systems and scale control in thermal distillation processes. The text explores corrosion control in cooling, boiler, geothermal, and desalination systems and it discusses the interactions of polyelectrolytes with suspended matter. Includes coverage of a range of bacterial species, including Legionella The book examines bacterial species commonly encountered in water supplies, the mechanisms of biofouling, approaches to control it, and criteria for selecting biocides for water treatment applications. An entire chapter is devoted to Legionella in water systems. Contributors describe various analytical techniques for identifying mineral scales and deposits. They also examine applications of polymers for treating industrial and wastewater systems and give an account of analytical approaches for monitoring various operational parameters and chemicals used to treat industrial water systems. A valuable addition to the library of academic researchers, this volume will also prove useful to those working not only in the water treatment industry, but also to those in petroleum, textiles, pharmaceuticals, and other areas where purity processes are a significant concern.

Providing the population of the Earth with safe drinking water is one of the biggest challenges of modern society. In recognition of this problem the United Nations Organization and UNESCO declared 2003 to be the International Year of Freshwater. On November 19-22, 2003, the NATO Advanced Research Workshop (ARW) on “Modern Tools and Methods of Water Treatment for Improving Living Standards” took place in Dnepropetrovsk, Ukraine. Thirty-one participants from 15 countries including Bulgaria, Canada, Croatia, Czech Republic, Denmark, Italy, Lithuania, Moldova, Poland, Romania, Russia, UK, Ukraine, USA, and Uzbekistan attended the meeting. They discussed the scientific concepts and practical means for the solution of the complex social, economic and ecological problems associated with water purification, consumption, conservation, and protection. They also established a network of scientists and specialists to foster further collaboration and the exchange of ideas. The location of the ARW was chosen quite deliberately. The city of Dnepropetrovsk is located on the banks of the Dnieper River and it has a population of about 1. 3 million people. As it is one of the largest industrial centers, it shares all the environmental problems, which are found in the modern Ukraine. In 2001, one in seven of the water samples taken from Ukrainian industrial and drinking water supply systems did not meet sanitary-hygienic standards, and one in twelve did not meet microbiological standards.

Focuses on the application of membrane technologies in removing toxic metals\metalloids from water. Particular attention is devoted to the removal of arsenic, uranium, and fluoride. These compounds are all existing in the earth’s crust at levels between two and five thousands micrograms per kg (parts per million) on average and these compounds can be considered highly toxic to humans, who are exposed to them primarily from air, food and water. In order to comply with the new maximum contaminant level, numerous studies have been undertaken to improve established treatments or to develop novel treatment technologies for removing toxic metals from contaminated surface and groundwater. Among the technologies available, applicable for water treatment, membrane technology has been identified as a promising technology to remove such toxic metals from water. The book describes both pressure driven (traditional processes, such as Nanofiltration, Reverse Osmosis, Ultrafiltration,etc) and more advanced membrane processes (such as forward osmosis, membrane distillation, and membrane bio-reactors) employed in the application of interest. Key aspect of this book is to provide information on both the basics of membrane technologies and on the results depending on the type of technology employed.

Soluble and insoluble impurities present in water used for domestic and industrial applications can lead to the deposition of unwanted materials on equipment surfaces. Impurities such as dissolved minerals, natural organic compounds, and suspended particles can impact various processes and systems including boiling and cooling processes, desalination, geothermal power generation, milk pasteurization, oil and gas refining, the pulp and paper industry, and biological systems. Understanding the mechanisms of scale inhibition and dispersion is important in addressing the resulting challenges. Mineral Scales in Biological and Industrial Systems presents developments in mineral scale formation and control in a variety of industrial and biological systems, providing in-depth discussions on topics important to academic researchers and industrial technologists. With contributions from experts in their respective fields, this book comprises 22 chapters in 5 parts. It begins by addressing precipitation and inhibition of various scale-forming salts—such as calcium carbonate, calcium sulfate, calcium fluoride, and calcium phosphate—in various industrial systems, including boilers, cooling, and high-pressure and high-temperature applications. Part II describes the precipitation and inhibition of salts encountered in sugar refining and geothermal power generation. Part III describes mineral scales that are important in biological systems. Part IV deals with the control of suspended matter in industrial water systems. Part V examines analytical techniques commonly used to characterize mineral scales and deposits during in-house evaluation of new products and deposit samples received for characterization from industrial installations, as well as product failure analyses. Covering the broad scope of mineral scales, this book both reviews current concepts and presents new information, with detailed discussions on fundamental and mechanistic aspects of mineral scale formation and inhibition.

The Select Committee report Waste Or Resource? Stimulating A Bioeconomy? (HL 141) advises that the UK could miss out on a massive opportunity to create a flourishing multibillion pound economy from waste. Although there are many kinds of waste generated from a variety of sources, the Lords inquiry looked specifically at waste which contains carbon. Around 100 million tons of carbon-containing-waste are available every year which could potentially be exploited as a resource. While preventing the creation of waste in the first place is a laudable policy goal, it is inevitable that there will always be waste, or unavoidable by-products such as orange peel, coffee grounds or waste gas from factories and power stations. Using cutting edge technologies, wastes such as these can be converted into valuable products such as fuels, flavors and fragrances, plastics, paint or pharmaceuticals. There are environmental benefits to be had from harnessing the was

This brief describes the development of a new model for realistically characterizing solution-diffusion transport mechanisms in polymeric membranes that are used for separation and purification of organic solvents. Polymeric membranes used in these environments, if not selected appropriately, undergo excessive swelling and compaction resulting in lowered performance or membrane destruction in the long-term. This brief describes the relationship between key parameters from a chemical, mechanical and thermodynamic perspective. Moreover, the authors show how this new model points membrane manufacturers, scientists, and engineers towards an understanding of how these key parameters are considered in (1) designing and manufacturing membranes for the right application, (2) designing the right test experiments to determine the long-term membrane behavior in a short time, (3) minimizing the number of experiments to determine a reliable membrane for an application and (4) selecting the right membrane with higher level of certainty. The overall benefits of the model includes saving money and time. A simplified version of the model is included to assist the reader.
