Who we are
We are focused on helping our municipal and industrial clients manage their environmental impact with the lowest possible lifecycle cost. EDI is recognized for excellence in exports and has received numerous awards including: State of Missouri “Small Business Exporter of the Year” Award and US Dept. of Commerce President’s “E” Award for Excellence.
Founded in 1975 with a focus on Biological Treatment and Advanced Technology Diffused Aeration Systems, the company continues to grow with its diverse product portfolio and unparalleled service capabilities; offering integrated aeration system solutions for Municipal and Industrial Water Reclamation Facilities. The corporate campus in Columbia, Missouri, USA is the R&D, engineering and design management, and manufacturing center for the organization; featuring world-class test facilities for oxygen transfer, material performance, and product design.
EDI continues to support new plant construction, existing facility upgrades, and long-term infrastructure demands on a global scale. To support our global customer base, we have created a network of direct sales representatives and local independent partners. In addition to sales support from the corporate offices, EDI maintains international offices in United Kingdom, Germany, Romania, Mexico, Japan, India, Singapore, and UAE. EDI diffused aeration products have been installed in over 8,000 aeration systems in over 100 countries serving over 400 million people.
In June 2020, EDI integrated into Nexom after having been acquired by KKR and XPV Water Partners. This integration empowers EDI for a much stronger position in the global market with enhanced, synergistic capabilities and a wider range of solutions in our integrated portfolio of biological treatment and filtration technologies.

Industry excellence: EDI has been recognized for excellence in exports and has received numerous awards including the State of Missouri’s “Small Business Exporter of the Year” Award, the U.S. Department of Commerce’s “President’s ‘E’ Award for Excellence,” or “E-Star” award. This E-Star award has only been granted to a select 300 companies since the inception of the program by President John F. Kennedy in 1961.
In June 2020, EDI joined the water quality platform now known as Axius Water, having been acquired by KKR and XPV Water Partners. This enables EDI to hold a much stronger position in the market with enhanced, synergistic capabilities and a wider range of solutions in our integrated portfolio of biological treatment and filtration technologies. Together with Nexom, our vision is for every drop of wastewater to meet the highest nutrient standards at the lowest possible energy footprint.
Sustainability
…is much bigger than the aeration systems we supply or numbers that show up on financial statements. As a part of the Axius Water platform, we are part of a global team that is meeting some of the critical challenges of our time with energy, determination, and creativity, at a growing scale that is making a real difference. Stronger Together, Axius Water’s 2022 Sustainability Report, shares the depth and breadth of how our platform is collectively addressing these challenges. You can download the report in full, but make sure to scroll down to discover how EDI specifically is contributing.
Encompassing nearly 4,500 square miles, the massive Chesapeake Bay is the birthplace of much of the shrimp, oysters, and other aquatic life in the northern Atlantic Ocean. However, the rivers that flow into the Bay are laden with pollutants from the enormous 64,000 square mile Chesapeake Bay watershed, which extends from Delaware, the District of Columbia, and Maryland into Pennsylvania, Virginia, West Virginia, and even New York. Nutrient pollutants (i.e., nitrogen, phosphorous, and ammonia), including fertilizer from farms as far away as New York State, collect in the Bay, where they create hypoxic or dead zones that kill fish and harm other aquatic life.
By helping its customers reduce pollution and improve water quality, Axius Water contributes to measurable progress toward SDG 6: Clean Water and Sanitation. EDI and Nexom design, manufacture, install, and service simple and sustainable technologies that enable small and remote communities to manage local waterway impacts with limited resources effectively.
Regulatory Compliance“I come to work excited every day, knowing that I am making a difference in the world by helping our clients achieve cleaner water. I’m grateful that my education and experience enable me to help people and our planet.” –Tanner Devlin, PhD EDI Regional Sales Manager
We provide services and products our clients use to monitor and manage the quality of their wastewater discharge to comply with regulatory quality standards. EDI and Nexom sales and applications teams monitor changes to North American effluent discharge regulations at the federal, state, and provincial levels and develop strategies to help customers achieve compliance.
Climate ImpactAxius Water strives to reduce greenhouse gas emissions, both directly in operations and through the implementation of technologies at customer sites. Because up to 70% of a typical wastewater plant’s energy consumption may be used to power the aeration process, EDI assists customers in optimizing their energy use by replacing, maintaining, or investing in the aeration process. EDI’s distinctive matrix membranes were designed specifically to operate at the lowest energy requirements for the longest interval, enabling customers to drive down their power requirements.

Waste ManagementWhile most of our operations do not involve or generate significant amounts of waste, we employ policies and procedures as necessary for the treatment, handling, storage, disposal, and regulatory compliance related to hazardous and nonhazardous waste, including chemicals. EDI and Nexom meet all requirements for the disposal of hazardous waste from operations. Most production processes do not produce hazardous waste.
Since we can’t cover the full breadth of ESG activities undertaken by Nexom and its fellow operating companies in the Axius Water platform, we’ve developed the “Stronger Together” 2022 Sustainability Overview.
We focus on creating a workplace in which employees feel welcome, affirmed, and safe. Axius Water is committed to creating workplaces that welcome and support people of all backgrounds. Soon, we are hoping to implement a DEI training program at EDI as well as ensuring the presence of an Affirmative Action/Equal Employment Opportunity program this upcoming year.
Worker Well-beingOur goal and responsibility is to return our valued employees safe and healthy to their families and loved ones every day. Our employees are mindful of maintaining robust health and safety programs that incorporate industry best practices and closely monitor our performance. EDI experienced three recordable employee injuries in 2021. In response, we have instituted Six Sigma standard protocols as it implemented routine observation facility walks to identify possible safety risks and proactively resolves any found issues. Reach out to our HR team to see about joining our growing team.
We operate according to the principles of responsibility and reliability so stakeholders can depend on us.
Sustainability, Governance, and StrategyWe place consideration of ESG issues at the forefront of everything we do because we believe it’s the right thing to do. While responsibility for Axius’ ESG performance is shared by the Axius Water leadership team, in 2021, the company appointed the senior vice president of operations to lead and coordinate Axius’ ESG initiatives. The Axius Water board of directors reviews Axius’ ESG performance as part of its quarterly business planning and review process.
Business ContinuityAxius’ operating companies strive to build operational resilience and maintain business continuity because wastewater treatment facilities must operate continuously, through all weather conditions, and thus require an uninterrupted supply of consistent quality products. EDI strives to build operational resilience and maintain business continuity to assure that we can deliver critical raw materials even during market disruptions.
Supply Chain ManagementLike Axius Water’s other operating companies, EDI took steps to strengthen oversight of labor, human rights, environmental, and diversity issues with their respective supply chains in 2021, with ATAC leading the way. We took steps to strengthen oversight of labor, human rights, environmental, and diversity issues with our respective supply chains in 2021.
Risk ManagementAt both the platform and operating company levels, Axius Water’s senior leaders take various actions to identify, assess, and manage ESG and other risks and opportunities. For example, in 2021, Axius recognized a risk management vulnerability and identified the need to more clearly articulate the scope and limits of authority delegated by Axius across the day-to-day operations of their companies. In response, in early 2020, Axius developed and adopted a Delegation of Authority policy covering commercial transactions, capital expenditures, employment matters, banking/treasury/investment matters, contributions and changes to the corporate structure, legal entities, and mergers and acquisitions.
We draw on decades of experience to create economical, effective, and sustainable solutions for clean water, and our customers define success using many terms, such as SOTE, power, space, NPV, Total N, P, BOD, and TSS. These terms may be rather technical, but what our customers really want is a positive outcome, not a product. Our highly experienced professionals have been offering deep application knowledge backed by unique services and technologies to assist our clients in providing cleaner, healthier water in communities around the world for 47 years. We design and implement innovative, cost-effective, sustainable solutions that help clients maintain compliance of the contaminants and nutrients that regulators are targeting today and into the future. Our ability to solve customer problems is evidenced by the number of our staff members who previously worked for one of our customers and were so impressed with our service level that they chose to join our team and provide that service level to other customers.
Building Local EconomiesEDI has deep roots in its local and regional community. We contribute to vibrant economies by providing rewarding careers, depending on local suppliers, and contributing to the expansion of U.S. exports. EDI has received both the Missouri Small Business Exporter of the Year Award and the U.S. Department of Commerce President’s ‘E’ Award for Excellence. Also known as the E-Star Award, this recognition is the highest recognition any U.S. entity can receive for making a significant contribution to the expansion of U.S. exports and has only been granted to 300 companies since its inception. Read more about how EDI continues to serve their community and country.

Innovating for a Better TomorrowAxius Water’s operating companies offer proprietary, eco-friendly treatment products and services that can replace outdated methods with current best practices and utilize information technology to enhance and remotely control process management.
Water Infrastructure Investments“At EDI, we value the voice of the customer and look beyond what standard “commodity” systems can offer. We have almost 50 years of aeration innovation and have always placed the highest regard on value for our customers while simultaneously recognizing our corporate mission: being good stewards of the environment.”–Patrick Ely, Regional Sales Manager, EDI Employee since 1988
In response to prolonged underinvestment in water infrastructure in the United States, the Bipartisan Infrastructure Law enacted in 2022 delivers more than $50 billion to the EPA to improve U.S. drinking water, wastewater, and stormwater infrastructure. Axius companies are advising and assisting customers on how they can best access and utilize funding from the single largest investment in water that the U.S. federal government has ever made. Axius operating companies possess innovative water treatment technology that can help customers achieve aggressive clean water goals and build future-focused solutions for the 21st century. As U.S.-based manufacturers, both EDI and Nexom produce clean water technologies that are eligible for projects funded under the Build America, Buy America Act, which is part of the Bipartisan Infrastructure Law.
