Produktbeschreibung
Provides a thorough overview of the process, equipment, and techniques used for softening water with potassium chloride (KCl) regenerant Sodium chloride (NaCl) is typically used to soften water, yet the resulting sodium-rich runoff has no benefits and poses human health and environmental problems. Water Softening with Potassium Chloride lays out an alternative approach that offers a "win-win" for both the environment and softening performance. Written by the pioneer of the process, this unique resource presents the background, research data and studies, pro and con arguments, and practical applications involved in using potassium chloride for water softening. The coverage in this comprehensive reference includes: * What is potassium chloride? * What is hard water? * Lowering water hardness * The ion exchange process * Basic chemistry of ion exchange * Operation and types of water softeners * Potassium chloride regenerant for water softening * Comparison of KCl and NaCl as regenerants * Environmental Insiderations * Potassium and human health * Ongoing research Along with the above topics, appendices describe a standard test protocol for comparing sodium chloride and potassium chloride and provide data obtained from a comprehensive comparison study. Water Softening with Potassium Chloride is an unmatched reference for professional water treatment specialists, environmental science researchers, students in these and related fields, as well as members of the public interested in making a positive impact on the environment.
Autorenporträt
WILLIAM WIST (deceased) spent eleven years at Central Canada Potash as a lab technician, senior chemist, and chief chemist. After joining Potash Corporation of Saskatchewan Inc. in 1980 as chief chemist, he set up and equipped a new research and development laboratory for them. From 1988 until his retirement in 2005, he was chief chemist and pilot plant supervisor. Bill spearheaded the research and development of the use of potassium chloride as a water softening regenerant, in addition to other projects involving potash product quality and analytical procedures. JAY H. LEHR holds a PhD in environmental science from the University of Arizona and an engineering degree from Princeton University. He is the author of twenty-eight books and over 600 journal and magazine articles. He has taught at the University of Arizona and The Ohio State University, directed a professional society of environmental scientists, and formed a variety of environmental teaching and consulting firms. ROD McEACHERN holds a PhD in chemistry from the University of Saskatchewan. He currently works as the Director of R&D with the Potash Corporation of Saskatchewan Inc. in Saskatoon, Canada. His research interests include the application of new technology to environmental stewardship through improved air pollution abatement equipment, improved waste management practices, and process improvements to potash operations.
