Better water & brine efficiency
The “Countercurrent” article by Peter Meyers in your December 2001 issue (“Countercurrent Regeneration of Softeners: Weighing the Pros and Cons,” pp. 42) is an example of a very learned person lecturing the masses.
The industry has marketed a half dozen brands of counter-current softeners and touted their salt efficiency, however, they sell well—and at a premium—not because of their salt efficiency but primarily because they produce better water. Peter mentioned the lower leakage levels of counter-current softeners. When applied to iron bearing water, less leakage is a good thing indeed. Contrary to Peter’s assertions, certain counter-current softeners are routinely used on 50 parts per million of iron, and I can show him systems treating in excess of 100-ppm iron. The Technetic, for one, uses a dedicated brine collection system and has been on the market for 15 years!
I won’t complain if government regulation increases the demand for counter-current softeners but I get far more satisfaction selling a technological advantage on its own merits. Still, thank you, Peter, for your opinion.

Wisdom of a few good words
I just went through your October 2001 issue and read your excellent editorial “Viewpoint: America Under Attack—September 11.” I felt I must write you about it.
I really loved the numerous quotes from famous people. These are tough times and it is a difficult subject to write on. It’s tough to say it better than the way these great people have said it. I really loved the JFK and Martin Luther King quotes. I also liked the fact that instead of talking about water-related issues, you looked at the bigger picture and how society as a whole has to come together to share the grief.
Seeing the dignity and the courage with which America has handled this tragedy, my admiration for your country has grown many fold. We share your grief and wish you the strength to grow from it.

The editor responds: Thank you for your comments. It was difficult choosing which quotes might be the most appropriate at such a time. As you can imagine, the range of emotions one feels after such an event is fairly broad. Following Sept. 11, it has been encouraging to be an American with the outpouring of sympathy over the tragedy from across the globe. We, as Americans, often don’t hear appreciation for efforts of many of us to help make the world a better place to live. We recognize our imperfections and work to overcome those. Unfortunately, some of that burden isn’t always pleasant, as in Afghanistan over the past few months. Let us hope something positive and lasting can come from this, and that any negative spillover to other areas can be avoided or minimized. Regardless, there will be a lot of work for us all to come in improving the quality of life of those in the region so that the sense of desperation that leads some upon such destructive paths dissipates like winter in a spring rain. Therein lies our function as an industry dedicated to improving the quality of water. Keep safe and may you and yours be happy and prosperous.
Correction: Colors on the hardness leakage curves in Figure 2 of Peter Meyers’ article “Countercurrent Regeneration of Softeners: Weighing the Pros & Cons” (WC&P, p. 42, December 2001) were inadvertently misidentified. Countercurrent flow should be in red, or the one with lower leakage. Co-flow should be in blue. We apologize for the error.
