That is consistent with what I observed. The units were about the size of a
25 KW generator and required a lot of understanding and tweaking to function
properly. The reason it came to my notice was everyone's amazement that the
engineer was able to get more water out than even the manufacturer
(DeLaval?) thought possible.

This wouldn't be a current option unless someone were to produce a scaled
down unit for trawler yacht size boats. Even larger craft have gone largely
to reverse osmosis because they are less troublesome to run and manage.

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.

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?

Does yeast figure into this anywhere?

I assume it does but I WAS trying to be a bit discreet. There mat be
some on this news group that have retained their innocence.....

a gift from a friend who bought a bigger one:

http://www.waterwise.com/productcart...p?idcategory=3
&idproduct=23

I was using a ceramic pot distiller someone had turned into a thrift shop
I'd bought for $5 because noone knew what it was for. I still have it
but it isn't near as efficient as this Waterwise countertop unit. The
lab one will distill continuously as it hooks to the sink faucet with a
special aeriator that has a fitting on it to seal the hose to and makes
about 12 gallons a day, if you need that much. It distills directly into
my 6" carbon column setting on top of a 5 gallon water jug for unattended
operation. But, it loses so much heat from its ceramic pot and I gave up
trying to insulate it for more efficiency after my friend gave me this
countertop unit which, other than the condenser fan outlet, hardly loses
any heat at all.

My friend got the biggest one, which runs itself in his garage, all
plumbed in to keep its exhaust heat out of his house in HOT South
Carolina. I makes water until its full, then shuts down until you use it
nearly up, with automatic feed like my lab unit has. It also runs on
220VAC with lots more power.

Just out of curiosity, how is the steam condensed? I watched the
animated show and that subject didn;t seem to be mentioned.

My mate uses a 3 inch stainless reflux still but he is running twenty
gallon batches.
