Disinfection Alternatives for Safe Drinking Water. (Library Corner).Edward A. Bryant, George P. Fulton, George C. Budd (1992) Readers will gain a thorough understanding of alternative methods of drinking-water disinfection--and how those methods relate to current and future U.S. Environmental Protection Agency Environmental Protection Agency (EPA), independent agency of the U.S. government, with headquarters in Washington, D.C. It was established in 1970 to reduce and control air and water pollution, noise pollution, and radiation and to ensure the safe handling and regulations--from this authoritative book. Written by three practicing engineers with many years of experience in the design of water treatment facilities, Disinfection disinfection, n the process of destroying pathogenic organisms or rendering them inert. disinfection, full oral cavity, n a procedure used to reduce active periodontal disease, usually completed within a certain short time frame. Alternatives for Safe Drinking Water drinking water supply of water available to animals for drinking supplied via nipples, in troughs, dams, ponds and larger natural water sources; an insufficient supply leads to dehydration; it can be the source of infection, e.g. leptospirosis, salmonellosis, or of poisoning, e.g. discusses trends and legislation, what's known about the mechanisms of disinfection, and the relative accuracy of techniques for determining the toxicity of chemicals. Detailed descriptions are given for each of the common and uncommon disinfection or disinfection-related techniques: chlorine, chloramination, chlorine dioxide chlorine dioxide, n an oxidizing agent used in oral care to decrease amounts of volatile sulfur compounds that may cause halitosis. , ozonation, ultraviolet radiation systems, membrane filtration, air stripping Air stripping is the transferring of volatile components of a liquid into an air stream. It is a chemical engineering technology used for the purification of groundwaters and wastewaters containing volatile compounds. , and activated carbon absorption. This comprehensive book explores many areas of interest, including * concerns about the formation of by-products during the disinfection process; * the use of ozone as an alternative disinfectant disinfectant, agent that destroys disease-causing microorganisms and their spores. Disinfectants, or germicides, are sometimes considered to be substances applied to inanimate bodies, whereas antiseptics, not so potent, are agents that kill microbes on living things. ; * the use of activated carbon to remove by-products and their precursors; * the use of ultraviolet processes and membrane processes as a new technology; * renewed interest in chloramination for secondary disinfection; and * the maximum practical use of chlorine dioxide within prescribed limitations. The authors make valuable recommendations on the upgrading and operation of plant facilities. They give detailed information on arriving at effective, low-cost water treatment plant designs that satisfy regulations and meet varying treatment needs. Emphasis is placed on flexibility of design and options for the future, so that plants can be updated further as regulations change. The book also features summary tables that can be used to quickly initiate a design study once the disinfection process is grasped. 518 pages, handover n. 1.
