Treatment of cooling water


Book Description

Many cooling systems use water as cooling medium. They are found in public buildings, industrial production systems or power plants. Almost every cooling system using water is degraded by deposition, corrosion and microbiological fouling. This book identifies the whole bunch of problems due to water cooling systems and proposes specific solutions to all of them. The authors have an expertise of over 20 years solving cooling water problems. In this book, they advise all practitioners which need to plan, buy or operate cooling systems.

Management of Legionella in Water Systems


Book Description

Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.

A Practical Approach to Water Conservation for Commercial and Industrial Facilities


Book Description

Industry and commerce use vast amounts of water and in some parts of the world water is becoming a scarce commodity. We need to take more care in our future use of water, and this book is a 'best practice' manual for industrial and commercial users world-wide. It offers a practical account of the measures which can be taken to re-educate industrial and commercial users in the techniques of water saving and re-use anywhere in the world. The principles are covered in detail and supported by examples from specific industries and commercial operations. Author Mohan Seneviratne is Manager of Sydney Water's 'Every Drop Counts Business Program', which won the prestigious 2006 Stockholm Industry Water Award in recognition of how the utility is working in partnership with business, industry and government to help ensure the long-term sustainability of Sydney's water supply.* The first book to cover water conservation for industrial users from processing plants to pubs and clubs* Provides practical advice on implementing water conservation for users in various industry sectors* Written by a practicing water conservation consultant




Process Technologies for Water Treatment


Book Description

The Brown Boveri Scientific Symposia by now are part of a firmly established tradition. This is the tenth event in a series which was initiated shortly after Corporate Research was created as a separate entity in our company; the symposia are held every other year. The themes have been: 1969 Flow Research on Blading 1971 Real-Time Control of Electric Power Systems 1973 High-Temperature Materials in Gas Turbines 1975 Nonemissive Electrooptic Displays 1977 Current Interruption in High-Voltage Networks 1979 Surges in High-Voltage Networks 1981 Semiconductor Devices for Power Conditioning 1983 Corrosion in Power Generating Equipment 1985 Computer Systems for Process Control 1987 Process Technologies for Water Treatment The tenth event in an uninterrupted series that by now goes back almost 20 years is a good opportunity to make a few remarks on the guiding rules that have governed our symposia. Why have we chosen these titles? At the outset we establislwd certain selection criteria; we felt that a subject for a symposium should fulfill the following three requirements: It should characterize a part of an established discipline; in other words, it should describe an area of scholarly study and research. It should be of current interest in the sense that important results have recently been obtained and considerable research is still being undertaken in the world's scientific community. It should bear some relation to the scientific and technological activity of the company.







The Science and Technology of Industrial Water Treatment


Book Description

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.
