Teaching People What They Need >

My normal focus in this blog is water treatment.  I am going to take a tangent today because my favorite blogger, Seth Godin, had a very interesting post last week titled “Give the people what they want” and the next line was “…isn’t nearly as powerful as teaching people what they need.” His posts are always thought provoking

Reduce Your Backwash Flow or Lament “Why is my ion exchange resin in the drain?” >

It is that time of year.  You must reduce your backwash flow in the Fall or you will find your ion exchange resin in the drain or waste treatment plant. Why do I need to reduce my backwash flow rate? If the backwash rate for an ion exchange system is set when the water is warm, the flow
