Water and Wastewater Treatment

INDUSTRIAL GAS SUPPLY & TECHNOLOGY FOR THE WATER & WASTEWATER TREATMENT INDUSTRY

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 Praxair, 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. Last year alone, we helped bring clean drinking water to 25 million people around the world.

INDUSTRIAL APPLICATIONS AND SYSTEMS FOR WATER & WASTEWATER TREATMENT

pH Control

By replacing stronger 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 solids generated through wastewater treatment.

Ozone And Sludge Reduction

Aeration & Odor Control

Our In-Situ Oxygenation (I-SO™) system dissolves oxygen into wastewater to increase bio-treatment capacity by over 100%. This low-cost industrial application provides excellent solid suspension, reduces foaming, increases dissolved oxygen (DO) levels, and decreases VOC emissions and odors.

Recarbonation & Remineralization

As one of the world’s largest suppliers of carbon dioxide, we offer everything you need for superior water treatment systems, 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.

Disinfection

Ozone makes a powerful disinfectant when it comes to water treatment. Avoid chemical residue while controlling unwanted microbial growth in your operation.

INDUSTRIAL SERVICES FOR WATER & WASTEWATER TREATMENT

Emergency Oxygenation Service

Our In-Situ Oxygenation (I-SO™) emergency service can quickly provide temporary oxygen-based aeration to solve water and wastewater treatment capacity problems or excursions resulting from inclement weather, power outages, excessive loading, spills and plant maintenance.

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.
