Water and Wastewater Treatment: Gases and Application Technologies
Pure Water Knowledge - For Today's Water Treatment Challenges
Innovative Gas-enabled Solutions for the Water Treatment Industry
Water is essential for all life forms, yet access to clean, safe water resources is becoming increasingly difficult in many parts of the world. All water used by humans and industry must be treated to increasingly tight regulatory standards before it can be safely reused or returned to the natural environment.
For decades, we have been working with water treatment plant operators and stakeholders worldwide to design and commission applications for gases such as oxygen, carbon dioxide and ozone in water and wastewater treatment processes. Our innovative and pioneering solutions help the wastewater systems sector to cost-effectively meet challenges such as better pH control for effective neutralization and remineralization, substitution of mineral acids, odor control, disinfection, as well as permanent and seasonal capacity increases. Our gas-dissolution equipment increases dissolution efficiency while lowering power costs.

Oxygen Instead of Air
Replace air with pure oxygen (O2) to increase application efficiency in water or wastewater treatment processes that require high capacity or high levels of dissolved oxygen (DO).
Neutralization and Remineralization with CO2
Substitute hazardous chemicals with carbon dioxide (CO2) to neutralize wastewater more quickly and safely without the danger of acidification or use CO2 to remineralize desalinated water so it can be distributed in the municipal network.
Pure Oxygen for Ozone Generation
Use oxygen (O2) as the feed gas instead of air to lower the lifecycle costs of modern ozone applications and realize the substantial power and capital savings possible when you switch to O2-based ozone generation.
Services and Customer Support
We support our customers at every stage of the solution lifecycle - from the initial assessment through application technology deployment to installation of a tailored gas supply system, always aligning our solutions with concrete operational challenges.

FAQs
How is oxygen used in water and wastewater treatment facilities?
Air can be replaced with pure oxygen (O2) in wastewater aeration schemes to increase the level of dissolved oxygen (DO) in the water. Higher DO enhances the natural purification of water by supporting the aerobic processes enabling biological treatment and disinfection, also helping to control odors, increase capacity, manage foaming, reduce sludge, avoid corrosion and manage costs.
How does carbon dioxide help water and wastewater treatment?
Carbon dioxide (CO2) for pH control supports the neutralization of water. When dissolved in water, CO2 forms carbonic acid, offering nearly linear pH changes at basic pH for precise pH control. Even with variable raw water characteristics, the pH can thus be easily and precisely adjusted without the danger of acidification. Neutralization with CO2 is often less expensive and safer than other mineral acids. In addition, CO2 and lime is required to remineralize desalinated water; it is the final stage after desalination allowing the water to be distributed in the municipal network to the consumer.
Why do I need ozone for water treatment?
Ozone is a powerful bleaching and purifying agent and - unlike chlorination-based chemical treatments - does not produce chemical by-products. It is often combined with other treatment stages - such as media filtration - in the treatment of industrial wastewater. It can also contribute to public health by helping to condition drinking water. To support ozone generation, we offer bulk oxygen deliveries and on-site oxygen generation systems.
Who can help me install my water treatment system?
We support our customers at every stage of the water or wastewater treatment solution lifecycle - from the initial assessment through application technology deployment to installation of a tailored gas supply system, always aligning our solutions with concrete operational challenges. Our water treatment experts will advise specifically on the correct sizing, installation and maintenance of your gas supply system, help you select a suitable dosing and flow-control system, set the correct O2/CO2 flow rate and advise on temporary gas dissolution equipment to cover temporary and seasonal peak loads.
Where can I run tests to see what gases I need and in what volumes?
We operate a global network of test centers and innovation labs to give our customers hands-on insights into the potential of gas-based solutions for water and wastewater treatment. Our experts would be happy to help assess your needs, develop a treatment strategy spanning equipment design, installation and gas supply, support you with proof-of-concept demonstrations and even organize on-site trials.
