Provides a thorough overview of the process, equipment, and techniques used for softening water with potassium chloride (KCl) regenerant Sodium chloride (NaCl) is typically used to soften water, yet the resulting sodium-rich runoff has no benefits and poses human health and environmental problems. Water Softening with Potassium Chloride lays out an alternative approach that offers a "win-win" for both the environment and softening performance. Written by the pioneer of the process, this unique resource presents the background, research data and studies, pro and con arguments, and practical applications involved in using potassium chloride for water softening.
The coverage in this comprehensive reference includes:

• What is potassium chloride?
  
  
• What is hard water?
  
• Lowering water hardness
  
• The ion exchange process
  
• Basic chemistry of ion exchange
  
• Operation and types of water softeners
  
• Potassium chloride regenerant for water softening
  
• Comparison of KCl and NaCl as regenerants
  
• Environmental Insiderations
  
• Potassium and human health
  
• Ongoing research

Along with the above topics, appendices describe a standard test protocol for comparing sodium chloride and potassium chloride and provide data obtained from a comprehensive comparison study. Water Softening with Potassium Chloride is an unmatched reference for professional water treatment specialists, environmental science researchers, students in these and related fields, as well as members of the public interested in making a positive impact on the environment.
