Even larger craft have gone largely

You can tell the Love Boat industry has gone to RO because of the number of
people who have been poisoned drinking it.

Not necessarily so Larry, We had 3, 3,000 gal/day R.O units on oil
production barges in the Java sea for about 5 years. While I agree
that they require maintenance they were far easier to maintain then
the exhaust heater and vacuum chamber distillation plant I maintained
in Irian Jaya.

The installations we had were commercial units with detailed operation
manuals. We simply followed the schedule for back flushing and
cleaning the membranes and they produced drinkable water for the
entire period we used them. We know that as we took weekly samples
from the tanks and had them laboratory tested as part of our
contractual obligations with the client.

On the other hand, people who either don't know, or don't care what
equipment they have and how to maintain it shouldn't use it.
