Hi Mark,
I’m not familiar with your system. Thank you for bringing it to my attention. Most of my design work is with commercial building clients – primarily retailers. I’ll definitely check it out. Maybe it’s something I can write a post about. If I have questions about it, could I contact you directly? If so, can you click the email me button on the site and send me a direct message?
Thanks for commenting on and checking out the blog.
Kevin

We have a product for commercial buildings that use cooling towers for heat rejection from HVAC systems. These systems typically consume tremendous amounts of water simply to evaporate it and remove heat. Some systems in large data centers can utilize 40,000 gallons a day and there are still larger consumers out there. As well, these users toxify the water by adding chemicals to have the water behave in certain ways to help the process and prevent fouling. Since the water is so hard in LA, the water needs to be drained “blowdown” after it cycles up to about 2 or 3 with traditional chemical. Our system allows the cycles of concentration of dissolved minerals to go well beyond traditional limits and increase cycles to 6 or greater. The higher the cycles the less you need to blowdown and make-up for the lost evaporation and draining. When speaking about large systems, we are talking about millions of gallons that can be saved for vital purposes.
Our system does this with the atmosphere and UV light. It is a simple inexpensive method to save water and keep the water behaving as necessary. Best of all, it returns to water and oxygen as it breaks down without any chemical toxification.
We can save millions of gallons of water if adopted in Los Angeles.
Thanks,
Mark
