RO/DI Water

I have a better solution. Combines pure water, vitamins and minerals. BEER ;D ;D

Hi ,

My wife and I have enjoyed R.O.D.I. water for many years now . You can't taste the difference between good quality R.O. water and R.O. D.I. water.
Most people do not want the expense of adding the D.I. stage to their drinking water . Can't taste it why bother .
I wish fish and corals were so forgiving .

If you top off with just R.O. water over time you will change the tank chemistry . With R.O. D.I. water you could in theory top off forever with no change in chemistry .
You may need to drink R.O. D.I. water in some areas of the country . The reason would be high levels of arsenic or nitrates .
So all in all most people do not need to drink D.I. water or pay for it .

In the ocean fish and coral live in a complete soup mixture of probably every time of mineral mixed with water

As for the relative potability of the pure waters, the difference in waters is very small. There is no adverse health affect from drinking distilled or deionized water. Deionized water tastes kind of bland & somewhat insipid, and distilled water has no taste at all. Some people get used to these qualities & drink them all the time. In either case, the taste is improved by aeration--if you shake the pure waters up with some air, the taste improves. The taste of any given water is largely imparted by the various mineral components; many of the drinking waters on the market today are, in fact, purified tap water to which minerals have been added (Avalon, etc). By law, drinking waters can not have more than 1000 parts per million of dissolved solids, so when you get down to the analysis of most available waters, there really isn't much difference between tap water, mineral water, or purified waters (no nutritional difference -->at all<-- between any of them!) As far as the health issue is concerned, it is true, water is hypotonic to cells & will destroy them. However, tap water is also hypotonic to cells. Your skin & stomach & intestinal linings are perfectly suited for thriving in and processing water. If you were to inject water into your blood, cells would die. If you cut your skin & wash the wound, the exposed cells do die. Fortunately, the fats that lyse out of the exposed wound quickly makes the wound less susceptable to water damage. Any ultrapure water you drink will quickly dissolve some saliva from your mouth--as soon as it has dissolved few parts per million of any substance, it is no longer ultrapure anyway. If it is a concern & all you have to drink is ultrapure water, you can stir the water with a metal stainless spoon or your finger first & it will magically transform itself from ultrapure water to just water.

Good find John,

I believe we sometimes get too tangled up in the 'detail'

Yes we could swap horror stories they he says this and she said that etc... but there is no fact saying one way or the other that DI is good or bad we could argue this till the cows come home. And no matter what anyone says you are going to do what you have your mind set to do.
They have ran multiple tests with DI water and it's effects and when time I will look for it if you really want to read. It is my opinion that for drinking water RO taste better then tap..our tap water here even though it now has no fluoride because the ro unit removed it. Good in some ways bad in other ways.

 

[quote author=builderguy link=board=General;num=1085673993;start=0#2 date=05/27/04 at 10:15:56]okay...but why does the drinking water bypass the DI filter?  Is it because of the cost and lifespan of the DI...that's my general impression anyway.[/quote]


Yes , that is the case for most people . You will find people that say you should not drink D.I. water , they usually recommend Distilled water . Basically the same thing D.I. water is just slightly better in quality than distilled water .
So they blow their own argument .

I have another question that gets asked a lot .
Does cycling the membrane on and off a lot with a float valve hurt the membrane ?
It is not so much the membrane that suffers. The short cycles cause a lower overall water quality in the storage tank .
When a membrane starts it's cycle it does so with very low pressure water, then pressures up to full pressure . It's the water produced at the low pressure that is not up to snuff. If you have very long production cycles this is not a problem . A very small amount of lesser quality water in a large volume .
The D.I. suffers the most , it has to deal with an increase in T.D.S. overall so it's life is shortened .
The real cost of this practice vs., the convenience is in my opinion not worth worrying about .
Now if you use very large volumes of water it would be a different story . We are working on reducing the cost of quality D.I. resin cartridges .

One note if you know any creative inventors that can figure out a delay for the float switch . Send them my way
