Hi Jim,

I came across your post while browsing and although I do not know much about textiles, I do know nearly everything about reverse osmosis. After reading your post, I had to come and mention that we are a reverse osmosis company, and we have systems that also consist of a de-ionization stage (http://www.aquasafecanada.com/store/...system-6-stage). I am not sure if this info is helpful, but if it is, and you have any questions, let me know.
