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.


Wouldn't it be fun to try to look at the lab reports on RO water from a
cruise ship that's in port just long enough to pickup supplies and the next
load of suckers for the craps tables.

Yes, it might well be enlightening. We did the lab testing because we
had to do it and report the results to ARCO on a weekly basis. One
assumes that they had some water problems in the past.

Another point was they we were 50 - 60 miles off shore and took our
water from roughly the depth of the barge. i.e., the intakes were in
the bottom of the one of the tanks so were feeding the thing with the
cleanest water available to us.

Interestingly the only major problem we had with the units, other then
sucking up a load of oily water before we moved the intakes, were the
seals in the high pressure pumps which were made in England. But as we
had a coupl;e of guys who crew changed to the U.K. we just had them
hand carry a bunch of seals back every time they returned from break.

By the way, I have a mate who is into the distilling business,
although he distills a mixture of sugar and water:-). What kind of
still are you using? A simple pot still or a reflux unit?
