Nitrogen Generation for Algae Prevention and Sparging

Nitrogen Generation for Algae Prevention and Sparging
Recommended Systems for Algae and Sparging

Nitrogen Cylinder Filling

Nitrogen Membrane

Nitrogen PSA

A few years ago our founder, Frank Hursey, made a fascinating discovery: When nitrogen is sparged, or bubbled, into liquids, the oxygen level is reduced to a point at which most biologics and all botanicals cannot survive.

Photo labs, food-grade oil producers, packagers, pharmaceutical plants, chemical companies, HVAC cooling water towers, and many others now bubble 97-99% purity nitrogen into chemical baths at low pressure to prevent bacteria and algae growth. Even if the surface of the water is open to ambient air, sparging N2 kills algae. Nitrogen is far less corrosive than ozone, and can be easily retrofitted to any recirculation or filtration system. We have worked on bulk carriers, oil tankers and ballast-water systems to develop nitrogen generators and hybrid systems that meet almost any sparging application. We can also design a nitrogen generation system that will custom size N2 bubbles to boost cost-effectiveness.

Recommended Nitrogen Systems for Algae Prevention and Sparging

Nitrogen Cylinder Filling
Nitrogen cylinder filling stations can be easily incorporated into any nitrogen generator system. We offer a convenient and reliable way to fill your own cylinders for a fraction of the cost of bottled-gas purchase and delivery.

Nitrogen Membrane Generator
The nitrogen membrane generator is a complete turnkey system. It arrives at your location designed and built to your specifications and you put it online.

PSA Nitrogen Generator
On Site’s PSA nitrogen generator technology assures quick returns on your investment and stable year-to-year gas costs.


Required Gas: Nitrogen
Purity Range: 95 - 99.999%
