Buffalo, NY, May 4, 2022 – 
Team members representing both CAIRE Inc. and AirSep Corporation recently had the opportunity to visit the completed upgrade to one of the largest sewage treatment plants in the southeastern US.

The Miami-Dade Water and Sewer Department, which serves more than 2.3 million residents and 20 million visitors annually, utilizes two AirSep ASV97000 VPSA Oxygen Systems. The project lead by global engineering company PCL Construction utilized the AirSep systems, making it the largest installation in AirSep’s company history. 

In attendance for the tour was Vice President and General Manager, Lawrence Hughes of AirSep, who invited along a very special guest for the tour – Norman “Norm” McCombs, former AirSep Vice President of Research and Development. McCombs pioneered air separation technology utilized at the treatment plant, the same technology which would later contribute to his pioneering the first portable oxygen concentrator, the LifeStyle, 20 years ago for medical patient use.

The Miami-Dade project included replacing the existing cryogenic oxygen system with two AirSep VPSA Oxygen Systems each producing 97,000 SCFH of oxygen. These are the largest systems AirSep has built in company history. These AirSep VPSA Oxygen Systems are for wastewater treatment and will enable the county to meet new guidelines and regulations. With AirSep VPSA technology, oxygen can be produced more cost effectively with an on-stream efficiency of 99%.
