What to do if the DEF tank gets contaminated

What to do when the DEF tank gets contaminated?

We couldn’t stress more on the fact that Diesel Exhaust Fluid has to be handled with specific equipment to avoid contamination, and therefore avoid damage to the SCR system that would be very costly. So you have all the equipment necessary and you are doing everything right, until someone accidentally mixes the Diesel Exhaust Fluid with another fluid. Although everything was going right, there is always a chance for human error. Depending on the size of the container, here is what you can do.

2.5 gallon bottles: Simply dispose it. There is no way to clean out the container after the Diesel Exhaust Fluid has been contaminated without compromising the integrity of any remaining product.

55 gallon drums: Just like the bottles, the product should be disposed. There is no way to clean out the drum after the Diesel Exhaust Fluid has been contaminated without compromising the integrity of any remaining product. Drums are the easiest to get contaminated, simply because anyone can open and close them. Drums are one way systems, and should be thrown out after each use. These are recyclable and preferred by small operations.

275 & 330 gallon totes : Although not as easy as the smaller packaged containers, you must dispose of the DEF if it becomes contaminated. We do not recommend cleaning out the container after the Diesel Exhaust Fluid has been contaminated, improper cleaning could compromise the integrity of any new product that can be stored.  We recommend contacting your local environmental waste disposal company for a nearby disposal site, they can advise were and how this can be done.Totes are meant to be temporary bulk containers, and can be reused, as long as there is a closed loop system and they are dedicated to DEF. A brand new tote, with a closed loop system, refilled only with DEF should never have contamination issues as long as the seal is intact.

DEF Tank gets contaminated

Above ground storage tanks & Underground storage tanks: We see this happening in places were there are multiple products being sold. The delivery driver can make a mistakes and off-load in the wrong tank. So not only is the DEF tank contaminated, but there is a high possibility that by the time the clerk figures out what happened, their customers have already filled up with the contaminated product. On a case like this it is important to give us a call so we can asses the damages. We would work on a case by case basis , to determine a plan of action. It is important to know that DEF contamination is considered an emergency and we would need to start working on a remediation plan immediately.

A cleaning crew would be sent out to the tank location as soon as possible. All the liquid would have to be disposed of, whether it is a mix of DEF and another product or even if it is just the other product. After properly cleaning the tank, a new load of DEF would be loaded, and a full lab test completed to make sure there is no contamination. Depending on the size of the tank, this process could take anywhere from 1-3 days to complete.

Purity down the line:

As the manufacturers we recommend to our customers to use the correct DEF equipment in order to keep the product clean down the line of distribution. We work with dedicated tankers to deliver our bulk product and avoid any cross contamination from the transportation of the DEF. For the smaller distributors we sell one way drums that should not be reused, as well as the bottles and totes. Totes come with a closed loop system, and can be refilled as long as the seal is intact. We recommend all our distributors buy totes from us, and discourage buying used totes, saving a couple pennies could cost thousands in damages in the long run.

NOx abatement part II- Why use NOXGUARD?


NOx Abatement

Continuing from our last blog post, which you can read here , we talked about what NOx is, why we need to control it and how each of us can help control it. As we all now know, industrial plants, and more specifically electrical power plants, generate a great deal of NOx , which contaminates our environment. There are several ways for these industrial plants to control their emissions, two of the ways are through the use of Selective Catalytic and Non Catalytic Reduction systems with a Urea Liquor mix (Diesel Exhaust Fluid at different concentrations). Different fuels need different NOx abatement techniques, for those that use Urea, we are here to shed some light.


What we know about SCR


  1. It is one of the most effective NOx abatement systems
  2. Has a higher initial cost
  3. Can achieve up to 94% DRE


What we know about SNCR

  1. Based on ionizing the Ammonia or Urea instead of using a catalyst
  2. Either urea or ammonia must be injected within a boiler or ducts where temperature is between 900 and 1100 degrees Celsius.
  3. Temperature has to be right, or ammonia will “slip through” or more NOx will be created than is reduced
  4. Can achieve up to 70% DRE


What is the difference between agricultural grade urea and NOXGUARD Industrial grade urea ( urea used for NOx control)?

Urea used for fertilizer is handled and stored differently than urea made into NOx control solution. High Quality dry or solution urea used in NOx control is kept in dedicated clean storage to ensure purity for both SCR and SNCR systems.


Why would a straight injection SNCR system need highly pure water or urea?

We know that the SCR system needs high purity water and urea, given the sensitivity of the catalyst bed. For the SNCR system if there happens to be any impurities in the solution they could be caked onto the nozzles and equipment in the exhaust zone. This can lead to clogging and could ultimately lead to costly damages in SNCR systems.


Why choose NOXGUARD for NOx Abatement?

NOXGUARD has spent many years on the technical process of making urea solution for NOx control in the automotive industry. Impure water and Ag-grade urea will not suffice in making urea NOx control solution. The water source must be removed of all impurities and de-ionized; if this is not done pollutants can damage the NOx control system. Fertilizer/feed grade urea can have contaminants, which will damage SNCR or SCR systems.


1.Nitrogen Oxides (NOx) Why and How they are Controlled


NOx Abatement part I- Did you know?

What are Nitrogen Oxides?

Nitrogen Oxides , the pesky family of NOx compounds, can come from natural sources or from human activity. They come mostly from automobiles and other mobile origins, but cars are not the only ones to blame,  electric plant boilers are also big players in the production of NOx compounds, as well as other stationary industrial sources. (1)

  • Mobile sources produce 50% of all NOx
  • Electric power plants produce 20% of all NOx
  • 30% comes from all other natural and human produced sources    



Why should we control Nitrogen Oxides?

The NOx family of air pollutants, includes NO2 (nitrogen dioxide) which is the most abundant in the atmosphere that is generated by human activities, as mentioned above. NO2 creates air pollution, ozone and acid rain; all which negatively affect us and certain ecosystems. There is scientific evidence that indicates that just 6-7 hours of exposure to ground-level ozone, even at low concentrations, can reduce lung function and cause respiratory inflammation. When exposed to high levels of ozone for several months, it can cause permanent structural damage in the lungs. Ozone doesn’t just harm humans, but it is the culprit for billion dollar losses of agricultural crop yield loss and damage to the forest ecosystem.(2)

How can we control Nitrogen Oxides (NOx)?

Be mindful of the car you buy, do some research to how clean and environmentally friendly your new care really is. When the words environmentally friendly and cars come together, most people think of slow boring cars which might not be too appealing. But there are other options, such as the Volkswagen Passat, and the Porsche Cayenne; they are both diesel models that use Diesel Exhaust Fluid to greatly reduce emissions. Industrial plants are now being regulated in the U.S and must have NOX control systems, in order to be in compliance. In fact, today August 3rd 2015, President Obama is announcing the Clean Power Plan, to cut carbon emissions from the power sector by 32% by 2030, compared with 2005 levels.  There are still many countries that have not adopted  NOX control standards for electric power plants or the mobile industry. It is important for these strict standards to be in place all over the world and not just in some countries, quoting President Obama ,” If we don’t do it nobody will. America leads the way forward…that’s what this plan is about. This is our moment to get something right and get something right for our kids.”

DI-Water, An inside look

We are very proud to share with you guys our new DI-water system here at Transliquid Technologies. In the process to grow and better serve our growing list of clients, we have been modifying the manufacturing process to become more efficient. As a short recap for those who are new to the DEF world, Diesel Exhaust Fluid is 32.5 percent automotive grade urea and 67.5 percent DI water. Water purity is key to blending the perfect batch of DEF, with out it contamination will occur; causing the SCR system to shut down and the diesel-powered engine will not run.

In order to have pure Deionized water, different filters are used throughout the manufacturing process.


    • Salt filter
    • Charcoal filter
    • Softener filter
    • Reverse osmosis
    • DI system
    • Scrubers




Although we have not changed this basic process, the new system is more advanced. Our new filtration system can handle a much larger water capacity, and can continuously regenerate itself, providing consistent water without exhaustion. The new system combines reverse osmosis and continuous electro-deionization (EDI).

Now more than ever we are prepared to provide our customers with top quality De-ionized water. DI-Water is used in many different industries, where completely almost 100% pure water is needed. Pharmaceutical companies, electronics systems and medical research companies all use Deionized water in their applications. It can also be beneficial to use Deionized water at home in any clothes steamers and irons, to prevent buildup in the machines.

Do not pee in your DEF tank, read why here!

We have been hearing over and over a comment about Diesel Exhaust Fluid that is particularly frightening ,

“Diesel Exhaust fluid is the same as ____ urine”           brown_cow_197654

Fill in the blank with any animal you can think of, we have heard it all but most recently , bat and cow urine. We have also heard of people thinking that urinating in their DEF tank will make the engine run. So the common misconception people have about Diesel Exhaust Fluid is that it is made from urine. This is NOT true, and acting upon this idea could cost you thousands of dollars in repairs to your SCR engine. On this blog, some light will be shed on the subject, and we will finally debunk this myth for good.

Those who believe in this myth used deductive reasoning to get to that conclusion , so according to them:

Urine = Urea

Urea+water= Diesel Exhaust Fluid

therefore Urine+ water= Diesel Exhaust Fluid


Urea Urea is an organic chemical compound, or the waste produced by the body after metabolizing protein. But since 1828, German scientist Friedrich Wöhler invented the process to create the synthetic version of urea. In 1870 the process of producing  urea through dehydrating ammonium carbamate under conditions of high heat and pressure was invented. So yes, urea can be obtained from urine, but lets find out why Diesel Exhaust Fluid is not just urine and water.

I will be comparing the material data sheets of  both automotive grade urea vs human urine.

  • According to wikipedia, “Human urine is an aqueous solution of greater than 95% water, with the remaining constituents, in order of decreasing concentration urea 9.3 grams/L, chloride 1.87 grams/L, sodium 1.17 grams/L, potassium 0.750 grams/L, creatinine 0.670 grams/L and other dissolved ions, inorganic and organic compounds.” Read the full description here.
  • Diesel Exhaust Fluid uses automotive grade urea, at 32.5% concentration. This urea contains , 0.3% Biuret maximum, 0.5 % magnesium max , 0.5 % calcium max, 0.5% phosphate max, 0.5% iron max,0.5% potassium maximum.

When comparing the two there are various differences:

  1. Human urine only contains 9.3 grams per liter of urea concentration
  2. Human urine also contains chloride, sodium , potassium , creatinine and other dissolved ions
  3. Human urine is 95% water, which is also full of ions and minerals

The water needed to create Diesel Exhaust Fluid has to be de-ionized and de-mineralized , a process that only a highly specialized filtration machine can achieve.


From all this information we can conclude that even though urine has urea, it is not the correct concentration nor does it have the purity needed. The water that comes from urine is also full of ions and minerals which make it very low quality water.


Diesel Exhaust Fluid is highly concentrated and very pure urea plus de-ionized water .The standards for Diesel Exhaust Fluid are very specific and can be found here

I hope that this blog has been informative, highlighting the differences between urine and Diesel Exhaust Fluid. Please do not urinate in your DEF tank, the SCR system will be damaged and it will cost thousands of dollars to repair.

Here at Transliquid Technologies we specialize in providing the best quality of Diesel Exhaust Fluid.

Earth Day 2015: Diesel Exhaust Fluid making a difference

Earth Day 2015
Earth Day 2015

Happy Earth day 2015! It has been 5 years since all diesel vehicles are required to come with systems to reduce particulate matter emissions and NOx emissions. Nearly all highway freight trucks, locomotives and commercial marine vessels are powered by diesel engines, making them a special target in the efforts to potentially reduce emissions and establish new fuel efficiency standards for commercial vehicles, the program has been put in place by the EPA and the National Highway Traffic Administration. Because we are part of the overall effort to create a cleaner environment for all, today is an extra special day for us Diesel Exhaust Fluid producers. We have come a long way in this new industry, which keeps growing every year. According to the DEF summit held last October by Integer, it is estimated that DEF consumption will reach 1 billion gallons in North America alone, by 2019. This means that every year, more and more vehicles will have the technologies to reduce emissions, leaving us with cleaner air to breath. So go out an celebrate mother earth, plant a tree, reduce, reuse and recycle all day long or simply learn more about the environment and how you can help to protect it!

4-step guide for keeping your DEF Dolly running great

I recalled a couple months ago, one of our customers came in with a Diesel Exhaust Fluid transfer Dolly that was not working. The Dolly was not broken, it just had not been maintained andDEF Dolly cared for properly.  It seems the customer was not using the machine correctly and or giving it the necessary maintenance; therefore it had started to malfunction.  It is important to take good care of any equipment that has various parts to it; a problem with one piece could make the whole system useless. If you follow this simple 4-part guide, keeping your Diesel Exhaust Fluid Dolly running smoothly will be stress free.Keep in mind the Dolly comes with a 1-year manufacturer warrantee.

Step 1: Maintenance of the pump parts.

Every three months rinse the pump with Deionized water. Deionized water is water that has had almost its entire mineral ions removed, producing high purity water; which is perfect for rinsing.Dolly pump

Step 2: Maintenance of the closed loop system.

The closed loop systems controls and manages purity throughout the supply chain to ensure the product does not get compromised. Because of this it is important to also rinse the closed loop system parts with Deionized water. 

Step 3: Maintenance of Exterior moving parts.

It is important to inspect all exterior moving parts every month or so, for any part that might be loose or damaged. If you are giving the Dolly a lot of use, some of its parts might have seen better days, checking for any broken or loose parts could save a headache in the future. Take a good look at your wheels; inflatable Dolly tires can get punctured. It might be better to go with solid tires as an upgrade if you will be using the Dolly in extreme terrain.  

Step 4: Hoses

Never attempt to disconnect hoses, doing so might cause damage to the sealants. It is recommended to roll hoses properly to prevent any accidental damage.

 If you only take away one piece of advice out of this blog, remember this; keep your Dolly clean and try not to hit it. Taking good care of it will make a difference it the life of Dolly parts.
