Re: [Killietalk] De-ionizing resins
I am not sure ion exchange is cheaper than RO in the long run,
especially if you use the "waste" water generated by the RO unit.
Also, if you need large amounts of water on a routine basis, it seems
to me the RO units are the way to go since a 100 gallon/day unit is
fairly inexpensive. Now, if you have extremely low conductivity
water to begin with, you can produce large amounts of DI water before
you need to recharge. As you say though, you can produce a larger
amount of water in a SHORT period of time with a resin system.
In my mind, it comes down to whether he can use the waste water from
the RO unit. In my situation, I have a low yield well so I put a 550
gallon reservoir in the basement fed by the well and then pumped it
into the house system. My waste water from the RO unit goes back
into the reservoir so I have no water waste at all. I realize that
is not an option for most people.
