Hey guys- This is a topic of conversation that has come up recently and we, of course, thought about sharing it here.

So, what is RO / DI (deionized) water and what are some of its applications for us here in Houston Texas.?

Well, for bigginers, DI water is simply water whose ions have been removed.  That is the basic answer.  An ion is a molecule with a particular charge (positive or negative) which means that the number of electrons do not equal the number of protons.

Side note: This stuff is fascinating now… not in my college days.

Moving on, let’s take a look at regular water, tap water to be more specific. Tap water runs underground , correct? This is very reason why tap water usually carries lots of ions from the earth and pipes.  In chemistry classes, DI water is preferred and the reason is that the ions in the water will cause interference and it will be more electrically conductive.

Looking at diesel exhaust fluid (DEF), we all know that DEF is made up of 32.5% urea and 67.5% DI water.

Why do we use DI water to blend diesel exhaust fluid here in Houston Tx?

Well, we already established that DI water is water whose ions have been removed.  Taking this further into DEF territory, what we are doing is removing the mineral ions.  If you take a look at the ISO22241 standard for DEF you will notice the list of minerals whose total content need to meet a low ISO standard.  The minerals include sodium, calcium, iron, copper, chlorides, and others. High metal content and DEF do not go hand in hand.

The brief description for the system is as follows: City water enters the premises, it then goes throught salt first, followed by charcoal filters, softner filters, Reverse Osmosis, DI system, one last set of final filters to produce very high quality DI water.

So, when we produe DI water for sale in either bulk quantities or smaller IBC tote quantities, all these things are taken into consideration and now you know what goes on behind the scenes.

Our water system can run 24 hours a day, conveniently located in Houston Texas.

Some of the tests you should expect to see when you request a certificate of analysis are as follows:

• Color and appearance
• PH by ASTM D1287
• Freezing point by ASTM D3321
• Corrosion tests include: Boron, Nitrites, Nitrates, Phosphate, Silicon…
• Age and wear indicators: Aluminum, calcium, chloride, copper, formate, glycolate, iron, magnesium, lead, sulfate, zinc.

Our water goes through a (DI)deionizer and (RO)reverse osmosis system.

We will be happy to provide you with our certificate of analysis.
