View Full Version : RO/DI water for drinking?

I just got one of these 6 stages RO/DI units from AquaSafe and was wandering if I can use output water for drinking or I need to bypass one of the filters.

Also, is Natural Spring water halthier than RO/DI water, since it has all these minerals or it's as good as RO/DI water with some multi-vitamin?

Was trying to fix my spelling mistakes and it gives a database error. Looks like there are no Update/Change permissions on the database file for the forum.

Player,
I use my RO/DI filter for aquarium and my own drinking water needs...... :rockon:

If my memory serves you should not drink DI water. You can drink RO water without any problems..

Someone please correct me if I am wrong.

I see no reason why you can't drink DI water, or RODI water, or RO water. They're all filtering techniques used to remove evil bad things from water. The purer the water, the better it is to drink for you (well, maybe you want that mind controlling flouride er something :)

RODI water is totally safe to drink. It's purer water.

Tapwater has Calcium and flouride in it which is good for you, and with the choramine & chlorine, it is less likely to get bacteria if stored, but who knows what else is in it?

With tapwater salt's will mix to a higher Calcium level.

For bottled water, I did see a few articles saying that Tapwater is better than many bottled waters because they add flouride to tap water, and there are stricter FDA regulations governing Tapwater then bottled.

i have heard many things as well..

the main thing i have heard is that DI water is pure water it has all the solvents removed from it that it has absorbed now by drinking it, It Absorbs the Minerals and sugars in our body's very fast witch in turn can be bad if you drink enough of it.. But again its alot of talk because i would just think fine it absorbs it but then our body's would just re-break it down right ?

Here is something to chew on :) I knew I read this somewhere and then I went to our work DI unit and looked in the "handbook for dummies" and found this. (I work in a research lab where we use this water for all experiments)


As far as employee health, you should not be concerned as long as nobody is drinking the DI water. DI water will actually suck the vitamins and minerals OUT of your body. Nobody is going to dissolve into a puddle of goo, but imagine drinking DI water as a way of taking a vitamin a day OUT of you. Getting DI water on your skin is fine, just don't drink it.



This actually makes perfect sense. Water will always try to reach equilibrium with whatever is around it. So if the water is completely stripped of dissolved ions it will take the ions out of surrounding tissue, and fluids to equalize the solution. So you in turn pee more good things out. This should not be a big problem as long as you don't drink gallons of the stuff a day.

As a side note DI water is corrosive b/c it will ionize metals. All the equipment in the lab says on it DO NOT USE DI water. I always wondered why till I looked it up.

RO water does not have any of the above problems.



Toooloud

I guess we were both writing at the same time making the same point :)

Your body will not re-gain the minerals and vitamins b/c you will pee it a lot of them out.

Hmmm that sounds interesting! The whole osmosis angle works for me, too. But dont tonnes of people drink RODI water?

Maybe we have too many ions anyway? Dont they sell de-ionizers that deionize your air or something?

Hmm, the last thing I want is water sucking vitamins from my body. I drink around 2L a day.

So I guess, if you bypass DI filter RO water would be fine for drinking, but bottled Spring water is still better as long as it's from reputable manufacturer.

This except was pulled from Reef Central by Aquatic Reef Systems (a sponsor of Reef Central):

In regards to the effects of drinking ro di and them being bad for your health...hmmmm

Yes RO DI water is very light as far as osmotic pressure goes and yes if you were to base your diet solely on RO DI water and nothing else you certaily would one day face a cell wall colapse.

BUT> I think that you would die of starvation before this would happen. Secondly as Randy mentioned if you take one bight of steak you have recaptured the small trace of minerals you have lost from the water.
Now if you go back and do a search on this subject you will see that I have never been an advocate of the mineral loss theory and the only reason I can say that DI water is not good to drink is because it doesnt have any taste.
I will repeat one statement I made in a past thread.
People become comfortable with things they recognise. this applies to the taste of food and drink as well.
The reason we like foods and sodas with sugar in them is because we recognize sugar as a taste we enjoy. This is a substance that over the years of consumption we have learned to identify very easily. Now the same concept applies to water. If we have been drinking mineral water or even hard water for a long time the minerals and hardness become identifyable to our taste and basicly we identify this as the taste of water. This is not the taste of the water it is the taste of the things in the water. The same concept could apply to soda, if you were to all of a sudden remove the sugar from the soda you would no longer enjoy it You would say that it tasted terrible and you could more than likely know it was absent of sugar and blame the bad taste accordingly. Now the problem with the water is that over time you have attributed the taste of the water to just being water and were unable to identify the individual minerals in the water that actually made it taste the way it does. SO when these minerals are removed now the water tastes (SUGAR FREE) and you no longer enjoy it as much.

As stated by DR Arthur L Guyton in 1991 The kidneys control the overall concentrations of the constituants of body fluids. It filters about 180 liters of water per day, over 99% is reabsorbed and 1 to 1.5 liters are eliminated as urine. If the osmolality of the fluid to be filtered by the kidney is lower than normal, nervous and hormonal feedback cause the kidney to excrete more water than normal and maintain the ion concentration in the body at normal values. The opposite is true if the ion concentration of the fluid to be filtered is higher than normal. The kidney homeostatic mechanism keeps the body fluid osmolality normal.The three basic hormonal and nervous control systemstriggered by abnormal ion concentrations are the antidiuretic hormone (ADH) from the pituatary gland, aldosterone from the adrenal glands and thirst because thirst is caused by a 1% rise in osmolality. Because of these kidney control mechanisms, drinking one liter of water would cause the urine output to increase about 9 times after 45 minutes and continue for about two hours. Thus the concentrations of solutes in the blood and other body fluids are quickly maintained by the the kidneythrough homeostasis. these control mechanisms keep the sodium concentration at 7%. Calcium concentration is controlled by parathyroid hormone to + a few percent in the extracellular body fluid. Also, Saliva increases the ion concentrations during water intake. The concentration of sodium chloride in saliva is typically 15 milliequivalents per liter or 877 mg/L that of potassium is about 30 milliequivalents per liter or 1170 mg/L. As low TDS water is consumed, it is combined with saliva which increases the TDS before it reaches the stomach to be absorbed. Each one millileter of saliva can increase the TDS level in eight ounces water consumed by about 10 mg/L. Basicly any changes from normal ion concentration will be corrected in one minute or less because of the fast pace of water through the cell membranes. Sosmall changes in osmolality (ion concentration)
are quicly brought to an equilibrium........

Beyond all of this If you wish to drink DI water I would suggest drinking non color change DI resin. Non color change resin is rated potable and approved for human consumptiom where color change resin is not.

Take care all and happy readin

Wow,

I was just wandering through the internet and found this.
That was years ago. It feels nice to be quoted :)
JUst to let you all know Im back in the bizz and would be happy to answer any questions you might have regarding water treatment, parameters, etc......

Good to see everyone still goin!

Has anyone heard of energized water , I heard it on Coast to coast AM

supposed to heal or something? it's RO or spring water i think?

Yeah, Cool concept really!

Energized water is water with a negative charge
This process is acheived by removing the protons from the water.
Heres a cool way to make your own. Get a battery, two peices of wire, a metal bowl. Follow these instructions

#1 Fill the bowl half way with water

#2 Hold the two pieces of wire to the positive and negative poles of the battery with the thumb and forefinger of one hand.

#3 Place the positively attached wire inside the container and the negatively attached wire on the outside above the water line.

#4 Pinch the wires together firmly for a second or two with the container side between them. You should feel no heat.

#5 In electricity, positive follows the negative and so some protons will be removed. This will leave the water with a mild negative charge. Electrons and protons tend to jump back and forth, so don't pinch the wires together for too long or you might not get the results you need.
