Oxidation Technologies will custom build a wide variety of specialized ozone applications. In the 9 months I have been working here, few projects have been the same. We have designed and built specialized pilot systems for customers exploring the new applications for ozone in their industry. We’ve produced a variety of systems for sanitation in the food industry and organic food storage. Our systems are solving tough problems in the pet products industry, and pharmaceutical research. We design systems for applications from bottled water treatment & dairy operations to municipal water, groundwater remediation, and sewage treatment. Our systems are helping customers in the ocean well drilling as well as the airline industry. We have designed custom treatment chambers for laboratories, allergy treatment, and product treatment. We’ve done in-house materials testing on a variety of dry and liquid materials. We continue to develop precise and safe control systems. Oxidation Technologies support the whole spectrum of ozone as well as other gas use with analyzers, sensors, parts and supplies. We have worked with customers all around the world. Everyone here works hard to understand needs and develop systems that will meet those needs. The leadership here have a tenacious spirit for overcoming obstacles and refuse to give up. The phones here are always in use providing excellent customer service. We are willing to travel and visit sites when needed or on a routine maintenance basis. From design to build, every project is steeped in cost consciousness, quality, the best materials and equipment for the job. Systems are built to work well, and last for a long time. After nine months working here, I continue to grow in my appreciation for the amazing potential of ozone, the depth of expertise laying the foundation of Oxidation Technologies, and the integrity and enthusiasm for applying the power of ozone to meet customers’ needs. At the same time, I have come to realize that what I have seen so far is only the tip of the iceberg. I am confident that the culture of growth and learning here will nourish my growth in understanding ozone and our ability to harness the power of ozone for your needs.
On Monday, August 20 the International Ozone Association (IOA) hosted an ozone process workshop giving an overview of ozone and Advanced Oxidation Processes (AOPs). Seven presenters representing various research organizations and water treatment operations around the country reviewed the basics of AOP fundamentals and considerations for safe and successful process operation and maintenance. Four companies set up materials for practical, hands-on instruction in feed gas, ozone generator and destruct repair and maintenance, ozone mass transfer, and ozone safety and monitoring. The discussion and problem solving generated by these presentations served everyone from the large treatment facility to specialized applications such as medicine, food production, or ground water remediation. I am very excited about this growing industry and will share some of the ideas and information that I am learning as someone new to the industry.
Ozone is commonly used to remove MTBE from groundwater and drinking water when MTBE is found in high levels. Ozone is a viable option as ozone oxidizes MTBE rapidly from water, and completely after by-products are also oxidized. Below paper gives great details on this process.

The aim of this work was to study the reaction of ozone and combined ozone/hydrogen peroxide on oxygenated additives such as methyl tert-butyl ether (MTBE) and ethyl tert-butyl ether (ETBE) in dilute aqueous solution using controlled experimental conditions. Experiments conducted in a semi-continuous reactor with MTBE and ETBE in combination (initial concentration: 2 mmol/L of each) showed that ETBE was better eliminated than MTBE with both ozone and combined O3/H2O2. Batch experiments led to the determination of the ratio of the kinetic constants for the reaction of OH°-radical with MTBE and ETBE [kOH°/ETBE/kOH°/MTBE = 1.7). Tert-butyl formate and tert-butyl acetate were identified as the ozonation byproducts of MTBE and ETBE, respectively, while tert-butyl alcohol was found to be produced during the ozonation of both compounds.

MTBE Removal Success
Ozone has proven to be successful at oxidizing MTBE in water. Ozone rapidly oxidizes MTBE, however, TBA (tert-Butyl alcohol) is formed as a by-product of this oxidation. TBA is then oxidized by ozone, but at a slower rate than MTBE. See chart directly below for a great example:
Image from: Chemical Oxidation of MTBE and TBA
The chart above shows a great example of MTBE removal in water with only MTBE and TBA data shown. As MTBE was oxidized, TBA was created at the same rate. After MTBE oxidation was nearly complete TBA oxidation started to occur, but at a slower rate. TBA will also be completely oxidized from water with ozone over time. Ozone remains a great option for oxidation due to the rapid oxidation of MTBE and complete destruction of both MTBE and TBA with no harmful by-products left in the water.

We just finished retrofitting a shed and installing an ozone remediation system in Wyoming. An Ozone Cabinet was used in a small shed to clean up gasoline contaminates in the water table.
This was a great install and very clean when finished. Small vent fans are used in this shed to remove excess heat. Ozone delivery lines were stubbed up directly inside this shed in the concrete pad making this a very secure install. A custom 2 lb/day ozone cabinet is used to provide ozone to up to 20 well outputs in this situation.
Ozone is a great solution to removing MTBE, TBA, BTEX, and other common gasoline contaminates from groundwater. Ozone can be used in-situ (as in this example) with minimal site disturbance and a very small footprint.

Groundwater remediation, as the name suggests, is the process of identifying and fixing groundwater problems, usually pollution or other contaminants. In some cases, groundwater remediation is the only way to solve potentially destructive environmental and health problems for whole communities. Groundwater remediation is a huge global industry, devoted to managing pollution. This remediation process has to deal with some of the world’s worst environmental problems on a daily basis.
Deadly Issues in Groundwater Remediation
Groundwater contamination is one of the most common, and most difficult, environmental problems. Contaminants may include oil, chemicals, heavy metals, and other poisonous substances. In some cases, contamination is so bad that water can’t be used at all. You couldn’t even use it to wash your car.
The other problem is that these contaminants will remain in the groundwater until the problems are solved. Prevention, obviously, is the best solution. In some cases, however, prevention and a cure must work together.
A good example of this type of problem is a case which occurred in Sydney. Serious contamination had released oil into groundwater. A total of 12 different types of contaminants were present in groundwater, including metals, in large quantities. These materials, if ingested, could be fatal to humans, or cause serious health issues. If released into the environment, the materials could also cause long-term contamination for fish and the local food chain.
The need was to both deal with the existing problem and prevent future problems. The solution was to develop a site-specific project to extract and eliminate contaminants using MyCelx filters, a top-of-the-line, modern wastewater filtration system.
Wastewater filtration and customized problem-solving delivered excellent results in this case. It should be noted that any incident of groundwater contamination may involve multiple factors. Each situation requires individual problem-solving and systems adapted to managing contamination issues.
Long Term Solutions
One of the major problems in groundwater remediation is simple enough – Understanding the problems. Most people don’t understand how dangerous contaminated water can be and how much damage it can do. Best practice is to implement long-term solutions using the latest technology to completely eliminate current groundwater and future contamination.
The bottom line here is that current problems can become expensive future problems. In many industries, groundwater contamination can also be a major legal risk. The good news is that MyCelx technology is drastically improving the cost efficiency of groundwater remediation. New treatments, new filtration systems, water purification systems, ozone treatments, and other advanced technologies are making the work easier, cheaper and quicker. The results speak for themselves.
