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.

The steam is routed, with only the pressure from the kettle sealed at the
lip and where it shoves on the pipe, no pressure at all, actually,
through a stainless tubing with a small fan blowing air through the flat
coil of tubing that's loosely wound so the air can get to the coils. Hot
air escapes out louvers in the top. This time of year, I leave it
running on my stovetop under the kitchen exhaust fan so the heat doesn't
have to be pumped out, once again, by the air conditioner. In winter, it
heats half my little 14 x 70 stationary caravan (trailer to the
Americans), recovering 100% of the energy it took to boil it.

The heat exchanger works very well as the water dripping out of it is
barely warm at the other end of the pipe. No steam comes out the open
pipe because of the contraction changing states from steam back into
water. My lab unit's boiler is too hot and some steam came out making
the whole house like a swamp if you left it run for hours and hours.
This tabletop unit from Waterwise doesn't do that. To see how much water
was lost, I did a test by dumping the distilled water gallon it makes
back into the boiler to see how far towards the maximum water mark it
came. It lost only about one mm of level in the whole process, so
virtually no water/steam is lost, very efficient, indeed. Of course, the
heat generated in the boiler eventually ends up coming out the top of the
condenser as dry heat after the condensing operation.

It's quite simple, actually. On a boat system, I'd look for a pipe-in-a-
pipe condensor of stainless, not copper like a marine AC uses for its
freon condenser. You'd get to pump the heat overboard in hot climates
with seawater condensing, that way. In winter, you could shut the
seawater pump down and blow cabin air over the condensor to recover the
heat to the cabin you were pumping overboard all summer. You only have
to drop the temperature below 100C to condense all the steam....much
easier than freon.
