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.... distillation is being used for the desalination of seawater, and reverse osmosis is being used to treat brackish and seawaters with TDS concentrations ranging from 500 to 36, 000 mg/1. Ion exchange is being used to deionize water for laboratory and industrial use. ... Another process, electrodialysis, has a TDS removal application range for concentrations from 1000 to 5000 mg/l. ... Since silver is a very noble metal, its domain of stability covers a large portion of a pE- pH diagram [41].
