came across this fact sheet

 

Oh hell, I think I overfilled the 550 yesterday. I don't think we're in danger of the DEF freezing though. Problem is the pump on the drum set-up has enough pressure to etch metal. By the time you feel the air rushing out of the neck the nest sensation you get is the DEF blowing out all over you. Thanks for the info.

 

soooo in summary diesel fuel in the def tank will #$&%#( up the o rings and cannot be flushed away. you have to replace al the system hoses and pump and o rings

DAMMMMM that could be pricey

they never say how the water is ultra purified? is it reverse osmosis, followed by filters down to 3 ot 5 microns? or is it steamed and condensed (distillation) then sent through reverse osmosis ,

and crystals on the injector area are normal and will burn off, so the def people stating that their def reduces crystals is basically Bull muffins as the urea does create crystals as the water evaporates
this sheet makes me even more want to use super tech or traveller at tractor supply if i cant find motorcraft.
i downloaded the sheet
thanks for posting

 

So in other words, if you follow the instructions in the owners manual, everything will be just fine.

 

No, no, no! You must do more! Only idiots who don't care about their truck follow what the owner's manual says.

 

If you follow the instructions in the owners manual, FORD will be fine.

 

DE-ionized water is made when they remove a ion from the water. Computer companies use that stuff all the time in manufacture of chips disks and other components that need to, be super clean. They buy it from a company that does this to the water This type of water is very caustic.

 

Distilled water is more caustic than deionized. But it's of no consequence in this situation. In continuously circulating systems, such as using in labs or in manufacturing, where the water is flushed and replenished, it causes the corrosion.

 

More DEF fun facts

there is a 32% urea DEF that we use as well as acMarine DEF which is 40% which’s is for large Marine engines.

the 40% doesn’t seem to be avail in less than 55 gallon drums.

i was wondering if the Marine DEF has a lower freeze point but could not find anything on that.

 

The greater the urea concentration, the lower the freeze point. You can look this up yourself. The difference between 32.5% and 40% is maybe 10 degrees, so from low teens to maybe zero.

Edit: I want to add that the higher concentration will trigger a dash warning for contaminated DEF.

 

yes it removes ions. no its not caustic or every house with a water softener would be blowing pipes from reaction to caustic water

"imply put, deionized water is water that has had all of the ionized particles removed. This is important because, once you remove any organic materials from the water supply, the vast majority of dissolved impurities in modern water supplies are ions such as calcium, sodium, chlorides, etc. An ion is a molecule that has a positive or a negative charge; iron ions, for example, have a positive charge. One of the ways to effectively purify water, then, is to remove these ions and replace them with hydrogen (H+) and hydroxyl (OH-) ions, which combine to make water. Check out our page about what DI water is to learn more terms and definitions related to deionization.

Curious about how to make deionized water? Before passing through a deionization (DI) system, water is usually filtered and often pushed through a reverse osmosis (RO) membrane. These pre-filtering steps do a good job of removing the organic matter and a majority of other contaminants. That means that the water is very clean before it enters the DI Water System. Check out our infographic on how RO and DI can work together.

Two ion-exchange resins are used to deionize the water. Positively charged ions (cations) and negatively charged ions (anions) are exchanged for hydrogen (H+) and hydroxyl (OH-) ions, respectively, due to the resin's greater affinity for other ions. After passing through both types of resin at least once, all that's left is highly purified water. Once depleted of exchange capacity, the resin bed is regenerated with concentrated acid and caustic, which strips away accumulated ions through physical displacement, leaving hydrogen or hydroxyl ions in their place."

they didnt mention freeze points, but one has to ask why is marine def a higher concentration of urea? is it that marine, rail, or stationary engines are running under high load almost 100% of the time?

 

But you can drink distilled water but you better not drink De ionized water.

 

If you read it on the Internet, it must be true. The Internet is a great tool that can wipe out ignorance or perpetuate it. Knowledge was the one great advantage paper book libraries have over the Internet. Nobody takes time to publish bad books. It's too labor and cost intensive to do in book form. Yes, I know not all books are proven true. Knowledge comes when one bothers to question what they read -and I'll give you a big clue as to things you should question: When someone takes a position they are advocating as knowledge and they don't indicate the "why" part, then you should question it or at least be curious as to why. That is why I generally explain "why" in a lot of my responses. Of course, I could be spinning a yarn, but at least there is a rational there.

As it turns out, you can drink both distilled and deionized water. You wouldn't want to do this ordinarily, but you could: https://www.uswatersystems.com/can-y...eionized-water

EDIT: Anyone who has drank either can tell you they are unpalatable. I know that can be subjective, but we know what natural water tastes like regardless of where we live even if it's chlorinated or fluoride. Even bottled water has a taste we are accustomed to. The minerals make a difference.

 

I use distilled water in my Cpap machine. I use it to wash my cars., Distilled water just takes the minerals out It doesn't change the composition of water. Its not the same process as de-ionized water where they remove a ion which doesn't sound like nothing. What it does is make the water try to regain that ion which makes it clean. They don't use any soap with de-ionized water. I wouldn't drink it for any reason. I don't know everything about De-ionized water just what I psted here.
