I hope that you are aware the RO units operate under the "ue it or lose it"
theory. If you do not operate it every 5 days, you need to backflush
(without chorine in the water) and use a storage agent.

I have a large on on my boat and do not even keep the mebranes in it.
Maybe on a long cruise where I cannot get water I will crank it back up.

Seagold desalinaters is one such unit and there are at least 10 other

only yeild 1 -5 leters of water an hour.. They work at increadably high

Wondering if anyone has heard/seen/had any such thing.

We have a 22' sailboat we would like to use it in brackisk/salt water as
well as fresh. Ability to carry it on hikes/camping would be great as
well. Large capacity is not critical (1-2 gal per day would be plenty).

There are plenty of purifiers on the market (Katadyn, First Need, MSR,
etc.), but none can desalinate.

Any leads would be appreciated.

Thanks,
Don

So is the trick to keep the membranes out and stored until such time
as you run out of decent tanked water?

No. I spent 2 1/2 years cruising with a watermaker. The trick is to
use it every day, then run some product water, about 1/2 a gallon,
through to rinse out the sal****er. Pickle if it won't be used for
more than about 3 days in warm weather, 5 in cold. Pickling is a snap
- just put a capful in 2 qts. of water and run it through. Then it's
good for a year.

Add a "silty water kit" or make your own. Just another inline filter
with a 5-micron element. I've made water pretty much everywhere with
this.

On last note. Don't get one larger than you need. Then you're wasting
Amp-hours and water to run it. It takes X Amp-hours per gallon of
water, whether you're making 1-1/2 gallons per hour (mine) or 500
gallons per hour.

Thanks for the primer. I didn't know you needed 20% of the production
to effectively flush the salt water afterwards.

Well, 20 minutes worth of running for the Pur 40E, 1-1/2 Gal per hour,
or 1.5 Amp hours. I don't find that bad for what you get. :-)

Neither do I, and I don't begrudge the "maintainence cycle". I was
simply unaware of the requirement.

Like having an electric windlass, it simply becomes part of the power
requirement, particularly if one anticipates making one's own power
and running an electric motor.
