Does anyone have recommendations on a brand of UV water purifier?
There seem to be one heckuva lot of manufacturers and I'd like to weed
it down before starting.

While UV magic MIGHT kill some bacteria in pond water, calling it water
purification is criminal.....

Of course, I'm the guy with the STEAM DISTILLER that makes PURE WATER, so
pure it doesn't conduct electricity....and tastes supreme with simple
activated carbon polishing to get out the distillates like Benzene, which
attaches itself nicely to activated carbon atoms. (Gives distilled water
that metallic taste.)

UV purification....that's almost funny!

Here's my favorite, a simple kitchen appliance that's very efficient and
makes about 1.2 gallons per load in a couple of hours. The condensor is
stainless steel, the carafe is polycarbonate. Neither creates a taste
and the carafe goes right in the fridge with a tiny footprint.

About 25c/load electric bill...not counting the air conditioning loading
from the Btu pollution coming out the top...(c;

We tested it against the seawater in the Ashley River at home. I
distilled a load of water straight out of the river, downstream from two
sewage plants by the way...tidal water. The resultant output was 3.2ppm
total dissolved solids on the meter and tasted just the same as city
water from the tap. Of course, the difference was in cleaning out the
salt, dissolved mud (well, maybe that wasn't mud) and dead biology left
in the boiler....including one boiled tiny crab.

I bet the crab would have survived UV "purification"....(c;

Dick,

UV does not "purify" water. With a high enough single dose, or constant
recirculation at a lower dose, you can "sanitize" water, and you can
break down dissolve ozone. With the amount of power you'd want to
consume on a boat, you'd be hard pressed to accomplish much with a UV unit.

I have been happy with several MiniPure UV system that I have had. I have
used them as point of use and, in my last boat, after the water maker prior
to going into the tanks. Smallest unit consumes about 14 watts.

If I'd said "disinfection" instead of "purification" would it have
been better?

A little. Only trouble with killing off the bacteria is the bacteria falls
apart, releasing some really nasty toxins into the water, after
"disinfection". This is what happens to people with RO systems. The
bacteria pile up on the membrane then the pressure breaks them down and
releases the toxins into the water flow, right through the membrane because
these toxins are tiny molecules the membrane can't filter....Makes you sick
as a dog. RO people don't like to talk about it....(c;

I have this thing about drinking dead bugs, too. I know I eat dead bugs
every time I put a piece of steak or chicken or dead pig or any veggie,
especially uncooked veggies like lettuce at the salad bar into my pie hole,
so I don't need to be reminded. Hell, the bugs in the salad bars are still
alive! But, I just don't like to drink them...(c;

Better dead bugs than the live ones I say. We've
been drinking RO water for about five years and
have missed out on a lot of the "flu" that has
gone around our neighborhood. Can't comment on
the toxins except to say that so far they haven't
seemed to make us sick.

One filter and membrane change in five years,
starting from city drinking water, and taking the
dissolved solids down from ~215 PPM to ~10 PPM
while taking out most or all of the bacteria that
has survived the chlorine. ==serious run on
sentence, but I'm gonna let it stand as written.

Larry, you gotta remember that the outside of the
RO membrane is constantly being flushed by the
water running past it. That is why we run 10
gallons of city water for each gallon of RO water
that we make. Now, I only wish that I could plumb
the flush water to water the plants and the lawn,
or something instead of just running it down the
drain.

Wow...I didn't know it would use a thousand gallons of water just to make
a hundred. I recover about 99.5% with the little distillers. The
boiler's nearly dry when the thermostat cuts it off.

Why couldn't you run the flush water into a 55 gallon drum with an
overflow to the drain, open to the air so there's no backpressure, then
use a sump pump with the float switch built into it in the "tank" to feed
water to the garden and lawn sprinklers? Harbor Freight has some dandy
sump pumps real cheap from the Chinese slavers. You'd have a 55 gallon
"reserve" when you turned it on, draining the tank into the yard when it
would shut itself down. Build it all into a storage building or in the
garage if you have one. I don't run the distiller in the house, except
in winter when I recover 100% of the heat to supplement home heating.
I'll bring it in from my storage building next month and run it from
midnight which eliminates heating the house for another month those
nights it runs.

I may have to reconsider where it's run after I get the Frybrid
(www.frybrid.com) installed in the diesel car. The storage building will
be full of "fuel" in 5 gallon plastic jugs, settling out solids from the
various restaurants for a month before I run it through the polishing
filters and into the car. That's going to consume a lot of space in the
shed...(c; I've got nearly 250 gallons per month promised from a group
of restaurants within a mile of home, if I want it. I'm going to have
free fuel running out my ears, shortly. I think a Frybrid-powered diesel
generator could take me totally off the grid to run nearly for free.
There's oil pouring out of restaurants all across the country, throwing
good fuel into the recycling dumpster they pay to have hauled off. How
stupid is that?

Yep, it burns a lot of water for that purified
drinking water.

Well, the real problem is that the RO system is
installed under my kitchen sink, with the purified
water tap beside the regular faucet. That is real
handy when you want a glass of drinking water, but
not so handy when you want to plumb the flush
water to run somewhere other than down the drain.

in winter when I recover 100% of the heat to supplement home heating.

If I built a new house, its would have the RO
system in the garage or a storage building, with a
recirculator and a cistern to use the flush water
for watering the lawn and flushing toilets.

Actually, if you are going to go to the trouble to
process vegetable oil for your car, you probably
should put in a diesel genset to run your home
also. You're already going to all of the trouble,
and the additional fuel to run your genset would
not add much additional hassle.
