I am Window cleaning resources official pure water expert.
In 1990, I started drilling artesian wells and installing home water filtration systems. I moved to a company in 1998 that designs and builds RO/DI systems. I have built systems as small as small as .5 gpm to as large as 60+ gpm. I am also a Massachusetts licensed plumber. Most of the problems window cleaners run across I dealt with everyday. If any one has any questions or problems feel free to call me 781-883-3107 or e-mail me at Bill@windowcleaner.com thanks.
I’d like to know if you guys have any deterioration of membranes or adverse effects on making pure water by the addition of fluoride to your public drinking supply. We have carbon block filters as a pre-filter for our RO units for chlorine, does this work the same for you over there? I always found it strange that you get flouride added to your water supply through the pretense of tooth decay - do you also add chlorine at a later stage down the line?
I have never seen any adverse effects removing fluoride with RO membrine. Most city’s and states don’t use chlorine any more. They now use chloramine it is much more stable and does not dissipate from the water before it reaches consumers much like chlorine will. It can be removed by treating the water with superchlorination (sodium hypochlorite bleach or pool sanitizer) I haven’t seen any problems with RO membrines so far.
