Hey ya'll! Go to: http://www.calh2o.com and you'll find a really good site about deionizing water. They also have a software package that's completely free, called CalCap95, where you can calculate how many gallons of D.I. water you can expect to get from a certain cubic foot of resin beads depending on the water purity that you start with (you'll have to get that info from your local water quality report, which I'm still trying to get a hold of here in Tulsa). Also there's a bunch of other good info about deionizing water...the whole process and explainations...good site. -Steve Gregory- ############################################################## TechNet Mail List provided as a free service by IPC using LISTSERV 1.8c ############################################################## To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TECHNET <your full name> To unsubscribe: SIGNOFF TECHNET ############################################################## Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information.
