Supplemental Dissolved Oxygen

Hydrogen peroxide is widely used to boost dissolved oxygen (DO) in activated sludge and other biological treatment systems. USP Technologies (USP) leads the way in safely and effectively applying hydrogen peroxide for this purpose. For over 20 years, USP has helped facilities like oil refineries, meat and poultry processing plants, petrochemical plants, and paper mills across North America.

In the aeration basin mixed liquor, H2O2 rapidly adds DO to the system according to the following reaction:

You’ll usually see higher DO levels within a few hours of starting hydrogen peroxide treatment. This method is especially useful when your plant encounters unexpected increases in BOD/COD loading, experiences mechanical aeration failures, or faces high influent temperatures that reduce oxygen transfer efficiency. Once conditions stabilize, you can easily stop the hydrogen peroxide feed with a simple command. Our customers enjoy the peace of mind of this dependable and easily implemented backup system.

USP offers a comprehensive solution with various hydrogen peroxide concentrations, advanced storage and feed systems, equipment installation and maintenance services, remote monitoring and controls, and industry-leading expertise in peroxide applications.
