Over the last several weeks, I have been in the field training technicians how to clean tanks and maintain clean, dry fuel. Fuel quality does not just happen all by itself. It takes a trained fuel quality technician operating a quality filtration and cleaning machine to get the job done. One of the ways Dixon Pumps differentiates itself among other fuel and tank cleaning equipment manufacturers is by providing in-field technician training. Take a look at the results of the last few training sessions.
We train technicians on the proper use of field equipment, giving them an advantage over others with little to no training. From learning how the machines operate, to proper site set-up as well as managing expectations. Some of the biggest challenges happen in the field when a technician comes across something they have never seen before. We help them to understand how common “new problems” can be in the field. Alleviating fears and instilling confidence in the process and equipment they operate helps the technician to overcome obstacles that many never do.
Our Mobile Tank Cleaning Unit, pictured above, is just one of several quality products Dixon Pumps manufactures. We believe in manufacturing quality products that are simple to operate. Combine this with the in-field training and you have a recipe for success. Let Dixon help you! Give us a call or email us for information and pricing.
Do you know what lurks in your tank? I spent the last week in Quito, Ecuador cleaning diesel tanks and training field technicians to do the same. Amazing what we found – microbial contamination, dirt, sand, deteriorated fuel and even a plastic bag.
Working at high altitudes, lifting fuel 16 feet at 9,000 feet of elevation was no easy task. Much less effectively cleaning fuel and tanks that had never been cleaned before. Amazingly, we were able to clean three tanks in two days and the big take-away for all of my trainees were – expect the unexpected. In my lifetime of working with fuels, I am constantly finding new things and learning. Just when you think you have seen it all, something new comes up.
Using our Dixon Mobile Tank Cleaning Unit with a Gamajet nozzle, we were able to clean the tank walls then filter the remaining diesel for an excellent result. Contact Dixon for help with your tanks!
The image above shows the progression of the product stream through a coalescer media. The emulsion is broken apart, filtering the solids, then forcing the minute water particles to coalesce (to consolidate or join up) into larger droplets. Gravity pulls the larger droplets to the bottom of the filter housing allowing it to be drained off during filtration. This is the first of two phases.
The second phase involves separation. A Teflon coated water separation filter is used to repel any fine droplets of water that happen to pass through the coalescer. This second stage acts as a secondary back-up forcing the water out of the product flow – not allowing it to pass through with the fuel. It works because Teflon is hydrophobic (literally, fear of water). The water repels off of the coated separator and falls down to the bottom of the filter housing.
Coalescer filters are designed to filter solids and separate two immiscible liquids (liquids that do not form a homogenous mixture – do not mix well). In this case, separating water from fuel. Dixon coalescing filters are made of several filtration layers designed to remove dirt particles prior to coalescence, thereby increasing filter life. Inner and outer layers are made of fiberglass impregnated with phenolic resin for added strength and bonding. Situated between these layers is a coalescing layer made of borosilicate microglass. Coalescer filters are commonly used in two stages along with a water separator to remove free and emulsified water from fuel and various types of oil.
In order to prevent carryover of small water particles pushed through during coalescence, a second filtration stage is used to ensure water removal. The separator is a cartridge placed between the coalescer and the outlet. The screen on the separator is a hydrophobic Teflon coated woven synthetic material which can be cleaned periodically.

Fuel testing is the only way to accurately verify fuel quality. There are many types of field tests and equipment available to identify problems. Field testing with instant or near instant results can provide a quick and responsive method for monitoring fuel quality. There are value tests available to measure water in ppm, acid number, microbial contamination and ethanol presence. There is also portable equipment designed to measure particulate contamination, water content, octane and cetane. The downside to the equipment is the cost.
- Acid Number, Ethanol Presence and Water detections test kits are available that provide results within ten minutes for under $20.
- Microbial Test kits take 48-72 hours to culture but cost less than $20. There are instant result test kits but they are much more expensive, priced over $175.
- Particulate Counters are available to test fuel inline while filtering or portably from sample bottles. Results are instant and ISO certifiable for those critical applications.
- Relative Humidity Sensors are also an option on the particle counters. They measure water in fuel.
- Octane and Cetane Test Equipment are available but expensive to own.
- Visual sampling is very important. Taking good bottom samples on a weekly basis can provide valuable information on what is taking place inside the tank.

Acidity is one of the major indicators of diesel fuel quality. Diesel fuel that has degraded will have a higher acidity level and be out of spec. Understandably, high acidity damages both dispensing equipement and engines. Common damage includes pitted fuel injectors and premature failure of fuel system components.
An easy and inexpensive way to determine the acidity of your fuel is to field test it with one of Dixon’s field test kits. Order a simple Acid Field Test Kit today from Dixon Pumps Cleaning and Filtration online store. The test is easy to use and results are instant.
Fuel quality management does not just happen. It starts with a sample. Unless you know what is in your tank, it is impossible to manage its quality. The first defense against fuel quality issues is regular sampling. Ideally, take a good bottom sample from the lowest access point in the tank at least once a week – more often if deliveries are made. If the sample is visually clear and free of water or large contaminants you can breath a little easier. However, clear fuel does not necessarily mean clean fuel. Because contaminates can be microscopic and still cause damage, they may not be easily seen with the eye.
Testing can also be periodically done to rule out any additional issues that might not be visible to the eye during sampling. There are economical field tests available that can detect water, acid level, ethanol and bacteria. Lab testing is also an option. While more expensive, it will provide a more detailed analysis of the fuel. For critical applications, this if very important.

It has become common to refer to fuel filtration or fuel polishing as tank cleaning. Don’t be confused! They are two different processes.
Fuel filtration, often referred to as fuel polishing, involves to cleaning of the liquid only. While there is some benefit to the cleanliness of the tank below the liquid level, it is not tank cleaning and should not be referenced as such.
Tank cleaning is most often one of two processes. The first involves manned or robotic entry into a tank amd includes the use of high pressure devices and scrappers to remove slug and mass contaminates.
The second involves the use of high pressure jet nozzles that are lowered into the tank. They rotate on a timing gear and clean the tank without manned entry. These devices are generally preferred over manned entry due to the reduced liability associated with a person enter a confined space.
Dixon Pumps is one of very few companies that offers a portable system that does both filtration and tank cleaning. So don’t be fooled by others that only do one or the other.
Dixon’s high quality cleaning and filtration systems are manufactured in the United States and made with ease of use and safety in mind.
