Oxygenation of wastewater

Using oxygen to increase the dissolved oxygen content of wastewater results in better system health and operability. If the current system is unable to handle increased loading or more stringent discharge requirements, then oxygen can be a low-cost solution in lieu of a major capital investment.

Dissolved oxygen can be impacted by our wastewater treatment solutions.  The removal of excess gases from air injection can be an easy way to decrease VOC emissions. Our oxygen injection systems can also reduce the amount of BOD and COD in water treatment plants and meet even the strictest water permit limits.



We offer equipment to meet specific oxygen consumption requirements, including VESTAL, VentoxAL, TurboxAL, PoroxAL, as well as spargers and other devices.


Air Liquide’s water treatment specialists will evaluate your specific site and design a solution that uniquely meets your needs.
