Download or read book Dietary Reference Intakes for Vitamin A, Vitamin K, Arsenic, Boron, Chromium, Copper, Iodine, Iron, Manganese, Molybdenum, Nickel, Silicon, Vanadium, and Zinc written by Institute of Medicine and published by National Academies Press. This book was released on 2002-07-19 with total page 804 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.

Download or read book Ozone in Water Treatment written by Bruno Langlais and published by Routledge. This book was released on 2019-07-16 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the advent of the Safe Drinking Water Act Amendments of 1986, many water utilities are reexamining their water treatment practices. Upcoming new regulations on disinfection and on disinfection by-products, in particular, are the primary driving forces for the big interest in ozone. It appears that ozone, with its strong disinfection capabilities, and apparently lower levels of disinfection by-products (compared to other disinfectants), may be the oxidant/disinfectant of choice. Many utilities currently using chlorine for oxidation may need to switch due to chlorine by-product concerns. Utilities using chloramines may need to use ozone to meet CT requirements. This book, prepared by 35 international experts, includes current technology on the design, operation, and control of the ozone process within a drinking water plant. It combines almost 100 years of European ozone design and operating experience with North American design/operations experience and the North American regulatory and utility operational environment. Topics covered include ozone chemistry, toxicology, design consideration, engineering aspects, design of retrofit systems, and the operation and economics of ozone technology. The book contains a "how to" section on ozone treatability studies, which explains what information can be learned using treatability studies, at what scale (bench, pilot, or demonstration plant), and how this information can be used to design full-scale systems. It also includes valuable tips regarding important operating practices, as well as guidance on retrofits and the unique issues involved with retrofitting the ozone process. With ozone being one of the hottest areas of interest in drinking water, this book will prove essential to all water utilities, design engineers, regulators, and plant managers and supervisors.

Download or read book IRON—Binary Phase Diagrams written by O. Kubaschewski and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the official dinner of a· meeting in May 1939, I was seated next to Max Hansen. When I congratulated him on the well deserved success of his "Aufbau der Zweistoff-Legierungen", he smiled: "yes, it was a struggle with the hydra, and so it has taken me seven years", meaning that whenever he had thought to have finished the phase diagram of a particular system, new evidence would turn up like the new heads of the Greek monster. There is no need to point out the importance of assessed phase diagrams to metallurgists or even anyone concerned with the technology and applica tion of metals and alloys. The information contained therein is fundamental to considerations concerning the chemical, physical and mechanical properties of alloys. Hansen's German monograph was followed by a revised English edition in 1958 with K. Anderko and the supplements by R.P. Elliott (1965) and F.A. Shunk (1969). All those who have made use of these volumes will admit that much diligent labour has gone into this work, necessary to cope with the ever increasing number of publications and the consequent improvements.

Download or read book Manganese Removal from Groundwater written by J.H. Bruins and published by CRC Press. This book was released on 2017-03-16 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Netherlands, Belgium and other European countries, manganese is removed by conventional groundwater treatment with aeration and rapid (sand) filtration. Such a treatment process is easy to operate, cost effective and sustainable, because it does not make use of strong oxidants such as O3, Cl2, ClO2 and KMnO4 with the associated risk of by-product formation and over or under dosing. However, application of aeration-filtration is also facing drawbacks, especially the long ripening time of filter media. Due to the long ripening time, water companies have to waste large volumes of treated water, making this process less sustainable. Also, costs associated with filter media ripening (man power, electricity, operational and analysis costs) are high. Therefore decreasing the filter ripening time, regarding manganese removal is a big issue. Although already extended research has been carried out into manganese removal, the controlling mechanisms, especially of the start up face of filter media ripening, are not fully understood yet. The emphasis of this thesis is to provide a better understanding of the mechanisms involved in the ripening of virgin filter media, regarding manganese removal and how to shorten or completely eliminate the long ripening period of filters with virgin material. This thesis therefore highlights the role of the formation of a manganese oxide coating on virgin filter media. Characterization and identification revealed that the responsible manganese oxide for an effective manganese removal was Birnessite. It was found that Birnessite, formed at the beginning of the ripening process was of a biological origin. Based on the knowledge that manganese removal in conventional groundwater treatment is initiated biologically, long ripening times may be reduced by creating conditions favouring the growth of manganese oxidizing bacteria, e.g., by limiting the back wash frequency and / or intensity. Additionally, this thesis also shows that the use of freshly prepared manganese oxide, containing Birnessite, can completely eliminate filter media ripening time.

Available in PDF, EPUB and Kindle. Book excerpt: This book is divided into three sections: the first reviews the main processes available for treating water for drinking (potable) purposes, the second goes into some detail about the design and operation of the non-filtration (clarification) processes, and the third deals exclusively with filtration and related applications. It is intended as a source of practical information rather than a theoretical research treatise and includes discussion of component parts of the process units with reasons for design features as well as operating principles.This book fills a gap between general reviews and research papers, and contains much information which is based on experience passed down within organisations and which tends not to be published.

Download or read book Removing Iron and Manganese from Underground Water written by Bart Polfliet and published by . This book was released on 2006 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract Almost all towns in the Ostrobothnic region supply their drinking water from the groundwater. As a consequence, the purification of underground water, to use it as drinking water is very important in this region. The hard climate in the region seriously limits the options for purification of the needed water. In the last ten years, a lot of work has been done in the field of water purification and distribution in this region. The quality of the underground water in the region is high, the only problems being high manganese and iron concentrations and sometimes high humus concentrations. Manganese is one out of three toxic essential trace elements, which means that it is not only necessary for humans to survive, but it is also toxic when too high concentrations are present in a human body. In addition to that, both iron and manganese give an unpleasant metallic taste to the water. The subject for this research project was chosen because pure drinking water is very important. There are countless possible methods to remove manganese and iron from water. It seemed like a good idea to test some of them, to see if the water purification system in this region could be further optimised. Most information on this issue was gathered from and international research program, to investigate future options and co-operation possibilities between the different Barents regions, in relation to drinking water production. In addition to that, most of the information on the current purification technique was found on the internet. For the project a number of samples will be taken from a purification facility. After the samples are taken, measurements will be done to determine the amounts of iron and manganese in every step of the purification process. When this determination is done, the samples will be subjugated to a number of experimental treatments. For this research project, the samples will be taken from the Kempele water purification facility. Good results were found after tests with a perchlorate or a hypochlorite treatment. These products seem to be able to remove the manganese rather fast from a water sample. Also, good results were achieved with a potassium hydroxide treatment. Towards the future, more research is required to see if these methods are also efficient in large scale situations. Also, some other treatments are advised to be researched, which were currently not possible due to limitations in the laboratory.
