This second edition demonstrates how chemistry influences the design of water treatment plants and how it should influence the design. Historically, water treatment plants have been designed from hydraulic considerations with little regard to chemical aspects. The many chemical reactions used for removal of pollutants from water simply cannot be forced to occur within current designs. This book re-examines this traditional approach in light of today's water quality and treatment. Will current water treatment processes be sufficient to meet future demands or will new processes have to be devised? Chemistry of Water Treatment assesses the chemical and physical efficacies of current processes to meet the demands of the Safe Drinking water Act, providing expert information to persons responsible for the production of potable water into the next century.

Life is impossible without chemistry. Engineering chemistry has a special role to play in the curriculum of under graduate students of all branches of Engineering. The present book entitled “ENGINEERING CHEMISTRY LABORATORY MANUAL” is very useful to Engineering students of various Institutions. The practical book providing simple and easy approach on the subject matter to Engineering students.

Whether you are a new employee or seasoned professional you need easy access to the latest test methods, updated quality control procedures, and calculations at your fingertips. You need to perform analyses quickly and easily and troubleshoot problems as they arise. You need a resource that is not only informative, but also practical and easy to use. Drinking Water Chemistry: A Laboratory Manual fills this need. The book gives you a thorough overview of the most basic, and therefore important, laboratory topics such as: Laboratory Safety - dos and don'ts based on real experience Sampling - preservation techniques, online sampling, and record keeping Laboratory Instruments - practical use ranges, principles of operation, calibration, conditioning, useful life and replacement, common quality control issues Chemical Use - reagents, standards, indicators, purpose and use, chemical quality and properties, avoidance of contamination, molecular weight calculations Quality Control - replicate analyses, spiked, split, and reference samples, percent recovery of standard, standard deviation, control charts, and everyday quality control measures Weights and Concentrations - care and analytical balances, mathematical conversions among concentration units, dilutions and concentration changes The remaining chapters cover test analysis including: reason for the test, type of sample taken, treatment plant control significance, expected range of results, appropriate quality control procedures, apparatus used, reagents, including function, concentration and instructions for preparation, procedural steps, calculations and notes on possible problems, and references. This is a working manual, meant to be kept by your side in the lab, not on the shelf in an office or library. You can bend it, you can lay it flat, you can take it anywhere you do your job. Useful and practical Drinking Water Chemistry: A Laboratory Manual provides the information you need to perform tests, understand the results, apply them to the determination of water quality before and after treatment, and troubleshoot any problems.

Environmental Chemistry, Eighth Edition builds on the same organizational structure validated in previous editions tosystematically develop the principles, tools, and techniques of environmental chemistry to provide students and professionals with a clear understanding of the science and its applications. Revised and updated since the publication of the best-selling Seventh Edition, this text continues to emphasize the major concepts essential to the practice of environmental science, technology, and chemistry while introducing the newest innovations to the field. The author provides clear explanations to important concepts such as the anthrosphere, industrial ecosystems, geochemistry, aquatic chemistry, and atmospheric chemistry, including the study of ozone-depleting chlorofluorocarbons. The subject of industrial chemistry and energy resources is supported by pertinent topics in recycling and hazardous waste. Several chapters review environmental biochemistry and toxicology, and the final chapters describe analytical methods for measuring chemical and biological waste. New features in this edition include: enhanced coverage of chemical fate and transport; industrial ecology, particularly how it is integrated with green chemistry; conservation principles and recent accomplishments in sustainable chemical science and technology; a new chapter addressing terrorism and threats to the environment; and the use of real world examples.
