Re: Watermaker Myths

I remember when I first saw bottled water at circle K and thought it was a joke and would never work, bottle of water the same price as a Budweiser WOW!!!

When I had my daughters (started late in life, had them before I turned 50 though) and the doctor told us to never use bottled water for the babies. That should tell you something in itself

Re: Watermaker Myths

I yearn for the days when as kids we all drank from the hose.

Re: Watermaker Myths

I started work as a sales rep in 1985. My boss had put a just introduced to the market bottle of water on top of his filing cupboard with a plaque that said "if you think your job's hard, be thankful you don't have to try and sell this stuff". How times have changed!

I think the de-evolution of humans is definitely taking place... getting much more dense.

Re: Watermaker Myths

Personally I never have understood why people drink bottled water in so called first world countries.
However we spent 10 years in China and would try to keep my mouth tightly closed when showering with the town water let alone drinking it.Even for the more affluent locals bottled water for drinking was pretty standard and usually in 20 litre fountain type containers but finding reputable sellers was always a challenge and we usually boiled it as well.
Not drinking your own RO water after spending many many $K I don't get that either .But marketing turns normally reasonably intelligent people into ???? when it comes to parting with their money.
Now where did I put my name brand boat shoes?

Re: Watermaker Myths

Man those guys would have fit to hear that many cruisers in the past drank muddy water off the side of a river bank in Africa and filtered through a clay pot!

Anyone that comes to our island house gets ice made from my rooftop cistern. Although we chlorinate, the only other thing we do is filter through a basic filter from Home Depot.

Never hurt anyone. We clean out the cistern maybe every 10 years.

Re: Watermaker Myths

RO is great at removing NaCl and most particulates. Viruses and many bacteria are smaller than H2O molecules and therefore get though the filter just fine. We drink our RO water, but only make water offshore or when we are at the front of a harbor on an incoming tide (and then only if necessary), and all of our water goes through a UV sterilizer.

Well, the title of this thread is "Watermaker Myths"

The size of the smallest known virus is ~5nm (in this case nm=nanometer, not nautical mile). The Na+ ion has a Van der Waals diameter of about 450 pm (picometers) or about 1/10 the size of the smallest known virus. And then water molecules have a Van der Waals diameter of ~275 picometers.

The RO industry uses a "standard" definition of 0.1nm as the pore size of RO membranes, or about 50 times smaller than the smallest known virus.

I don't think there is an RO manufacturer out their that sells their system as capable of virus or bacteria removal, but that is more a function of the regulatory environment than the capabilities of the process.

Here is what the CDC has to say:

Quote:
Reverse Osmosis Systems

Reverse Osmosis Systems use a process that reverses the flow of water in a natural process of osmosis so that water passes from a more concentrated solution to a more dilute solution through a semi-permeable membrane. Pre- and post-filters are often incorporated along with the reverse osmosis membrane itself.

A reverse osmosis filter has a pore size of approximately 0.0001 micron.

Reverse Osmosis Systems have a very high effectiveness in removing protozoa (for example, Cryptosporidium, Giardia);

Reverse Osmosis Systems have a very high effectiveness in removing bacteria (for example, Campylobacter, Salmonella, Shigella, E. coli);

Reverse Osmosis Systems have a very high effectiveness in removing viruses (for example, Enteric, Hepatitis A, Norovirus, Rotavirus);

Reverse Osmosis Systems will remove common chemical contaminants (metal ions, aqueous salts), including sodium, chloride, copper, chromium, and lead; may reduce arsenic, fluoride, radium, sulfate, calcium, magnesium, potassium, nitrate, and phosphorous.

Please explain how a bacteria can be smaller than an H2O molecule.

This should be entertaining....

Re: Watermaker Myths

Folks...

I have a case of bottled water aboard. I'm saving it in case I get thirsty while fixing my watermaker.

That's funny we carried 2 x10 litre bottles around for two years just in case all else went wrong.Drank them at home last week.
