[QUOTE="Shadowrider, post: 2722025, member: 3099"] That's allota salt. I figured they were using the heat off of the process somewhere. The unit I ran was really two identical ones on one pad. We were using it for wastewater treatment for removing chromic acid (chromium trioxide, otherwise known as hexavalent chrome. The bad stuff). I could boil the piss out of 85 degree solution water. They are doing it right by filtering and centrifuging it first. The distillate should be about as pure as you can get. The chemistry and the equipment I had didn't require any filtering because it was all soluble metals and it wouldn't have done a thing. The condenser and evaporator coils were inconel so we didn't even have to adjust pH. Just put it in and clean water came out, but I did have to adjust the pH up afterwards, but there were no metals at all. I could do 1500 gallons in an 8 hour shift off of only one side and each side had a large vacuum pump and a V4 multistage refrigeration compressor running on 480V 3phase. I'd hate to see the electric bill on that beast. [/QUOTE]
