210 Pinks and Blues: Concentration Ratio

Welcome to Scaling UP! H2O, the water treaters’ podcast. For newer listeners, something I try to do at least once a month is to take listener’s calls or show suggestions and answer them in episodes we like to call “Pinks And Blues”.

I LOVE taking your questions and talking about them on the show, and today is no different. We’re talking about Concentration Ratio on today’s Pinks and Blues Episode. 

Now that term might be a little confusing because there are 2 terms for the same thing: Cycles of Concentration AND Concentration Ratios. Don’t worry about it, I’m going to break down for you why I like the term “Concentration Ratio” and how using that term with your customer will help you build a better relationship with your customer.


Bottom line: Join me as we scale up our knowledge so we don’t scale up our systems.

Your roadside friend, as you travel from client to client.
