Composition of air: 78% Nitrogen; 20% Oxygen
Doesn't it seem very inefficent to compress air with 78% useless nitrogen to get the O2 required for aeration? It is.
Investigate the use of a highly efficient VSA O2 generator coupled to one of four (4) different methods of dissolution offered by PurO2. Make and USE 93% pure O2.
Below see a PCI "DOCS 200" VSA unit that delivers 840 lbs O2/day and a containerized "DOCS 1500" unit that delivers 6300 lbs O2/day.
