PSA: DO NOT DRINK RO/DI WATER REGULARLY.

I've read lots of people drinking their RO/DI water regularly. It isn't safe. Ultra Pure water strips your body of minerals and nutrients. It's ok to drink once in a while but please do not drink it regularly as it can kill you.

What you are referring to is called osmotic imbalance. Osmoregulatiom is the process that takes place in your body. In order to have a serious issue with drinking rodi water, one of two things would need to be the case.

1, you just guzzled a gallon of rodi in a minute or two.

2, you regularly drink rodi, but eat or drink nothing else.

Since the second option isn't very likely, I'd say #1 is the most likely scenario.

 

I regularly drink rodi water. I have been for about 2 years now. That's not all I drink, but it is all the water I drink.

Bull crap! Read my response to your other inaccurate post. There is no scientific evidence to back up those claims. The WHO has been perpetuating this myth for decades but has been unable to back it up. Eat a sensible diet and drink whatever makes you happy. Utter garbage.

Sorry, Nips. As usual, you are correct.

 

Op, thank you for saving my life. From now on its only chemically treated tap water for me!

RODI is no different than D5W (5% dextrose in free water) that i give patients IV on a daily basis... minus the sugar....

 

the above are right. as long as your solute load is good (ie you eat food with salts in them), you will be fine.

 

for more info on how to hydrate, check out the WHO ORS handouts if you are actually worried about optimal hydration.

*caveat* - drinking anything to excess can kill you. use common sense.

these are not peer reviewed AT ALL. this is essentially internet sorcery claims! "ultra pure" water is a made up term.

 

if you want a real term, the words you are looking for are "primary polydipsia". seen a lot in psychotic patients.

 

here is some real reading to help clear this up (google):

I definitely read "Amish Jain" and was so confused at first.

Since you know so much about water. I ended up buying a spectrapure water filter. But the DI cartridge comes with a warning that it's not safe to drink the water due to the not having FDA certification. Can I safely ignore it and drink it?

DId you know RO/DI is Dihydrogen Monoxide?!?!?!?

D: Don't you know they use it to strip PAINT off things and it corrodes iron. Imagine what it's doing to your insides!

YOU CAN'T TELL ME HOW MUCH TO DRINK OF ANYTHING.

Drinking "normal" water is bad for you (even fatal) too under the right conditions, like running long distance in the desert. It would be better to drink say... bloody mary mix under those conditions. It's why drinks like powerade, gatorade, ect are popular with sports to replace electrolytes since you lose more than just water sweating.

 

Generally people eat enough (or too much!) salt and such in their normal diet, RODI is nothing to worry about.

Yes you can ignore that label. DI resins do not carry an NSF label because their primary purpose is not drinking water. Why would Dow or anyone else spends years of time and millions of dollars to certify it for potable use when it's purpose is producing lab or medical quality water? Rubbermaid Brutes carry the NSF certification because they are used in the food preparation industry but they don't for their Roughnecks or totes made from the same materials in the same factories on the same moulding machines because they are used for trash or storage. Still safe though.

Spectrapure websites take:

 

When it comes to drinking DI water, there are many different thoughts on it. First thing you should understand is that DI water has all minerals removed. If ALL you were drinking was DI water and you did not eat anything, it would be harmful. Cells in the body need electrolytes (salts) to stay active and produce more cells. So, if you are not replenishing the electrolytes, the cells could not survive. To better illustrate this: Imagine that you have two batteries. One batter is connected to a glass container filled with tap water, the other is filled with DI water. Tap water is able to conduct the electricity through it because of the minerals. DI water cannot because the lack of minerals. It is only when you add salt to the DI water, that you would be able to conduct electricity.

DI water does not necessarily harm your health unless it is the only thing that you are putting into your body. We would not recommend drinking it because of its flat taste and because DI resins are not made of food grade approved material.

 

 

FYI, a quick google pops up venders selling food grade DI resin so I'm guessing its just a warning based on what spectrapure uses in theirs in case someone tried to sue them for something stupid cuz this is America. You could just swap it if concerned.

I've been drinking the RO part for years, beats buying cases of bottled water or lugging 5gal water jugs to the supermarket.

 

The DI part goes to the tank. I only drink that if I go out and eat something extremely salty (like certain food trucks).

If you don't mind me picking your brains a bit more i have quite a few questions! The waste water that comes out, what exactly is it? Is it just carbon filtered water, can i use it for drinking? Also my friend wants to go into waste water management and he would totally appreciate some insight as to what you guys to and how you got there!

 

Thanks again!

The waste has been through the sediment and carbon filters but not the RO membrane so it contains not only it's original TDS but also the TDS left behind from the water osmosed through the membrane. The waste TDS will be 20-25% or more higher than the tap TDS was to begin with. Along with that any residual chlorine disinfectant has been removed so no, I would not recommend drinking it or using it for pets or food preparation. You can water plants or the lawn, wash clothes or whatever but i prefer to send it to the sanitary sewer treatment plant to be recycled and used over and over again.

I oftenthought about using the waste water for a tanganyikan cichlid tank. I just don't know what other nasties would be in that watr.

Something you may not know but if you have drank a cup of coffee from that famous place everyone seems to love, you have drank RO/DI water. Many if not all of them use large Spectrapure RO/DI systems then run it through their Coffee Lovers remineralization resin cartridge to add just the right minerals at the perfect levels. I have a buddy that services them here in AZ.

Nepotism. At least thats how it works in my city. Trainee and level ones start at about $65k a year here plus full benefits and a pension. I have a friend that works for the city and he got in because of his uncle. Yes they hold these large hiring events. Last one I went to had over 500 applicants. I have passed the all the test and have made it to the final interview process 5 times. I gave up after the last one. My buddy told me that the person they hired was the 20 year old kid of a foreman for the city and the one before that was a guy that spent 6 years volunteering with the city and already had a part time position with the city. My friend claims its rigged to hire relatives....things like the relative getting copies of the test as study guides is not unheard of. Having a class A or B driver license helps. Also you can take classes at community college to prep you for your certs. Good work if you can get it. I wish your friend luck.

 

 

Yes it is safe to drink. I find it bland and not that tasty to drink. Like stated above Starbucks uses large RO/DI units I think they run it through a final mineral stage. The reason they do this is to ensure your coffee taste the same no matter what location you get it from.

 

This thread cracked me up. If you want good tasting water from your RO/DI just spend a little cash on a T, a couple check valves and a pressure tank. You can bypass your di stage for drinking water.

That's what the railroad is like... at least that's the perception. I've had a few people tell me I only got hired because I was military. Everyone else is military or has family on the railroad. However, there was a guy who interviewed 8 times before being hired and his father in-law was pretty high up in the company... regardless these type of jobs are super competitive and I'm sure there is a fair amount of "luck" that goes into them.
