Supplemental Dissolved Oxygen

The use of hydrogen peroxide to supply supplemental dissolved oxygen (DO) to activated sludge and other biological treatment systems is well documented and has been successfully practiced for decades. USP Technologies (USP) is an industry leader in the safe & effective application of peroxide for this purpose and has implemented numerous programs at facilities across North America for over 20 years. These include oil refineries, meat & poultry processing plants, petrochemical plants and paper mills to name a few. In the aeration basin mixed liquor, H2O2 rapidly adds DO to the system according to the following reaction:

Increases in DO can be usually be observed within a few hours of starting peroxide feed to the system. Adding hydrogen peroxide helps maintain optimal DO levels when treatment plants experience unexpected spikes in influent BOD/COD loading; have failures to mechanical aeration equipment; or see increased influent temperatures – which reduces the efficiency of oxygen transfer by mechanical aeration equipment. Once upset conditions pass and the treatment system regains normal operations, peroxide feed & associated chemical expense can be discontinued with the push of a button (or click of a mouse). Our customers enjoy the peace of mind of this dependable and easily implemented backup system.

USP’s turnkey and zero-capital supply scope includes a range of hydrogen peroxide product concentration options; state of the art storage and feed systems; equipment installation & maintenance services; remote system monitoring and controls; and the most experienced peroxide applications experts in the industry.
