I know that the Dialyseas system, an extremely expensive dialysis
water exchange system, has been discussed in this newsgroup before.
It is produced by a company out of Florida.

Their Website has pictures of some pretty darn elaborate setups that
this company has made using this system (especially this one)

I find it difficult to believe that someone would pay on the order
of 100K (guesstimate) for a turn-key system like this one that did
not work well.

Still I have not heard any feedback, positive or negative from actual
owners of this system.
