Physical Water Conditioning - 122

This presentation explains the chemistry of hard water, why scale forms, and the problems it creates. It looks at the conventional method of treatment and the drawbacks, especially environmental, associated with it. The presentation goes on to explain the science behind physical water conditioners and classifies them into three generic types, explaining the limitations of each and the design criteria that is important in specifying them. We also look at the code requirements for treating hard water and the test protocols currently available. A number of case studies evaluating the cost savings and environmental benefits will be shown.
