A Gulf Coast Refinery was using hydrogen peroxide (H2O2) in 55-gallon drums at their WWTU Bio Unit to supply supplemental dissolved oxygen (D.O.) to maintain target D.O. levels in the aeration basins during high COD loading periods. The drums were stored on wood pallets, which violated industry safety standards and...

ABSTRACT

In 2015, a maintenance turnaround of the wastewater aeration tank was undertaken at United Refining Company in Warren, PA. During the planned 70 day turnaround, the refinery needed a temporary chemical oxidation program to maintain compliance with permitted effluent phenol levels. This paper will present data and key learnings...

Abstract

Free Nitrous Acid (FNA) is the active agent underlying a new biofilm removal technology (“Cloevis”) for controlling sulfide production in wastewater force mains. The technology was developed at the University of Queensland and, after initial field testing in Australia, commercial field tests in the U.S. began in late...

A Southwest wastewater treatment facility was experiencing vapor hydrogen sulfide and mercaptan odors in the headspace of one of their pump stations. USP Technologies (USP) provided a proprietary vapor fogging technology (VFT) which involves fogging a dilute mixture of hydrogen peroxide (H2O2) and sodium hydroxide (NaOH) into the enclosed vapor space to oxidize H2S and mercaptan...
