My capstone/plant design final project is to design a wastewater treatment facility that outputs ultrapure water. Your page has provided so much information to me. It's so accessible, some of this information would have taken me much longer to sift through papers and textbooks to find. Thank you so much! | |

We've never had to chance to meet, but just wanted to point out that your website has been a very valuable tool. Thanks so much for your dedication to Ion Exchange, those wonderful little balls of chemistry! | |
