Water & Wastewater Treatment


We don't waste water. We renew it.

We develop and deliver customized systems to help industrial plants and municipalities meet their wastewater management goals. We work directly with our customers to provide beginning-to-end treatment methods, from needs assessment and treatment strategy to equipment design, installation and industrial supply. And we offer a wide range of applications that treat and reuse process water, all while maximizing treatment capacity, reducing VOC emissions, improving safety and reducing costs.

But at Airtec, we do more than treat wastewater. As the global demand for potable water continues to rise and fresh water supplies are quickly depleting, we’re advancing industrial technology to make this life-sustaining resource accessible to a growing population.  

Treatment Options to Improve Your Productivity

Many industrial processes are water intensive. The wastewater from these processes will contain contaminants, chemicals, biologicals and other compounds that will impact water resources and a company's compliance record. It’s no easy task to run your water treatment facility as efficiently as possible while still meeting capacity demands and environmental regulations.

By providing industrial and process gases for water and wastewater processing in a variety of industries and municipalities, Airtec helps facilities to reliably meet their water and wastewater treatment guidelines. We have extensive experience in using carbon dioxide to reduce pH in alkaline water for the water and wastewater industry. We also are well versed in the benefits of high purity oxygen for aerobic digestion, oxygen-enhanced aeration and the production of ozone for a variety of uses. Improving your process can help manage peak demand and capacity increases, increase plant flexibility, and lessen your facility's impact on the environment.


pH Control

By replacing mineral acids with carbon dioxide, you can lower pH levels more accurately without impacting your safety processes.

Ozone Sludge Reduction

Our Lyso™ ozone sludge reduction process is a low cost, highly efficient industrial application that reduces the amount of excess secondary sludge generated from wastewater treatment.

Aeration & Odor Control

Aeration & Odor Control

Our In-Situ Oxygenation (I-SO™) system dissolves oxygen into wastewater efficiently to increase secondary aerobic wastewater treatment capacity by over 100%. This effective industrial application provides excellent solids suspension, reduces foaming, increases dissolved oxygen (DO) levels, minimizes/eliminates VOC emissions and odor.

Recarbonation & Remineralization

As one of the world’s largest suppliers of carbon dioxide, we offer everything you need for superior water treatment, providing complete analysis and technical support to determine how much carbon dioxide is required to adequately treat water to a desired pH and restore a balanced mineral level.


Ozone makes a powerful disinfectant when it comes to water treatment. It removes odor and color while controlling unwanted microbial growth in your operation.


We do more than provide industrial gases, technologies and applications to the water & wastewater treatment industry. We’ll help you to optimize every step of your process. From consultation to implementation and use, we offer a range of services that help you monitor and manage your gas supply so you can focus on making your water cleaner.
