Industrial gas supply for water and wastewater treatment industries
Eliminate water waste and renew water resources
Praxair Custom Systems help industrial plants and municipalities meet their wastewater management goals. We work directly with customers to provide a full process approach, including demand assessment, processing strategies, equipment design, installation and industrial gas supply. In addition, our various applications can process and reuse process water to maximize processing capacity, reduce volatile organic compound emissions, improve safety and reduce costs.
Praxair can do more than just waste water treatment for you. With the growing global demand for drinking water and the rapid decline in fresh water resources, we are continuously introducing new industrial technologies to enable this life-sustaining resource to adapt to the growing population needs. In just one year, we have successfully provided pure drinking water to 25 million people worldwide.
Industrial gases for water and wastewater treatment industries
As an industrial gas, oxygen can be used as supplementary or even replacement gas in the aeration tank to maximize processing capacity, minimize volatile organic compound emissions, reduce odors and foam, and increase flexibility . Oxygen can also be used as a raw material gas for water disinfection.
Carbon dioxide can be used as a safe alternative to inorganic acids to lower pH, reduce costs, and increase equipment safety and flexibility.
Industrial applications and systems for the water and wastewater treatment industry
Using carbon dioxide instead of a stronger inorganic acid can more accurately reduce the pH value without affecting safety production.
Ozoneized sludge reduction
Praxair Lyso ™ ozonation sludge reduction process is a cost effective industrial application that reduces excess solids generated during wastewater treatment.
Aeration and odor control
Praxair's In-Situ Oxygenation ( I-SO ™) system incorporates oxygen into wastewater to increase biological treatment capacity by more than 100%. This low-cost industrial application can provide optimal solid suspension conditions, reduce foaming, increase dissolved oxygen (DO) content, reduce volatile organic emissions and reduce odors.
Recarbonation and remineralization
As one of the world's largest carbon dioxide suppliers, Praxair has many solutions required for water treatment systems, which can provide complete analysis and technical support to determine the water quality needed to adjust the water quality to the required pH and restore the balanced mineral content Amount of carbon dioxide.
Ozone can be used as a powerful disinfectant in water treatment, avoiding chemical residues and controlling the growth of harmful microorganisms during operation.
Industrial services for the water and wastewater treatment industry
Emergency oxygenation service
Prax Field Oxygenation ( In-Situ Oxygenatio , I-SO ™) Emergency services can quickly provide temporary oxygen aeration to address water and wastewater treatment capacity issues or deviations due to severe weather, power outages, overloads, leaks, and plant maintenance.
Praxair not only supplies industrial gases, technologies and applications to the water and wastewater treatment industries, but also works with you to optimize the entire process. From consulting to implementation and practical use, Praxair provides you with a complete set of industrial services to assist in monitoring and managing industrial gas supplies to focus on producing cleaner water sources.
