Both Sea Recovery and Spectra units are available in a modular configuration.. mine is

ebs001 mcollins, these units will not desalinate, they are made to remove desolved solids from city water.

110v Home RO unit?

I noticed that Sam's Club has 110v house (non-marine) Reverse Osmosis units for about $170, a lot less than marine watermakers. I don't remember the pressure, but I believe it operates at about half the presure of a marine RO unit. Does the operating presure effect the final purity, or just the rate/volume? Has anyone tried to adapt this type of RO unit to marine use or used with seawater?

Actually I'm going to agree and disagree.

I fully agree that larger is better. Ours does 12.5 gal/hr on about 20 amps and I should have found the room for the next size up as it does 16.67 gal/hr on 22 amps.

I disagree that you have to fresh water flush after every use. Sea Recovery recommends flushing only if not using with 2 weeks of use. We run ours almost every day [when running genset or engine - so free power] and never flush between. We only flush when not going to use for more than 3-4 days between. Then it's automatic and runs the water through a charcoal filter to insure no chlorine etc gets to membrane.

sailhog What does watermaker water taste like? A little like the sea?

Valiente Thanks, Mr. Dog. I am trying to ascend the logic tree one branch at a time...

sailingdog Valiente-

Having a separate tank for the RO watermaker is an excellent idea. Also, having the ability to transfer water between the RO tank an the other water tanks is an excellent idea.

Should I run out of "collected" water, I can hand-pump the osmosis stuff to the other tank and keep making it until I'm nicely ballasted. If I'm approaching a known source of decent fresh water, I can pump it back. Waste not...
