Whole house water filters...

[Guest guest]

RO filters require pressure to operate. For that reason they are more

suited to tub filling than showers. Also their flow rate makes a

reservoir, a storage tank, necessary if used for large applications.

http://www.ge-merlin.com/ is a page about the GE Merlin which

produces 3/4 of a gallon a minute. That could be used to charge a

cistern and a small pressurization pump can then provide cistern

water to the house. Bacteria control in cisterns is often done with

chlorox. I do not think that is a good way. When I lived in Montana I

had a cistern and I purified it with peroxide (food grade) A 55

gallon barrel of 35% was around $350. You dont want to use too much

as it will rot clothes in the washer just as chlorox will. I used 1/3

cup in 500 gallons.

 

The easiest task is putting a system together for drinking and

cooking as that will be most of your exposure to fluoride.

 

RO filter is similar to rain water and if it has any acidity that

would be due to CO2 exposure. Normally it is immediately consumed

after dispensed so absorption of CO2 wont have time. Like rain water

it has the greatest hydration potential.

So if you feel that is a worthwhile claim great. I find most claims

are about trivia and are for salesmen. But if you want to dissolve

something pure soft water has the most ability.

 

For measuring pH http://en.wikipedia.org/wiki/PH use pH paper or a

meter

 

I dont know of any consumer type books about RO. You might see if

your local library will get this book for you if you are interested

in the technology.

I am glad there is RO because distilation has to be non cavitating

(non boiling) if you want to leave the crud behind. Boiling

aerosolizes and carries minerals and metals across. Thus it would be

large to do the job.

 

The Merlin has the lowest overhead of commercial filters that I know

of. I have a lawn so that isnt a problem - (waste water.) Otherwise

it is down the drain. You can wait an hour to fill the bath tub. Tubs

such as Jacuzzi have heaters

Soft water leaching. - Urine will contain more minerals than the RO

water ingested. In the grand scheme it is microscopic. A salesmans

issue. In Asia rainwater has been used as safe potable water for

generations

You might want to share this with the group - I have put a lot of

information here.

 

BTW http://www.unep.or.jp/ietc/publications/techpublications/techpub-

8e/jar.asp is something I mean to do when I get time. I personally

think pH is important especially with the denatured food we eat.
