Reliability in the Face of Supply Chain Disruption
Background
Ferrous and ferric salts are critical chemicals for numerous drinking water and wastewater applications. There are four main types: ferrous salts, ferric chloride, ferrous sulfate, and ferric sulfate. Within anaerobic digesters, iron chloride salts are the main tool for H2S and struvite control. They are produced by the steel...

Struvite Reduction via H2O2 and Ferric Chloride
Background
In 2017, JEA was presented with two methods to control struvite formation at several points in their biosolids handling system at the wastewater treatment plant. One method utilized ferric iron (as FeCl3) to complex with phosphorous to interrupt the struvite potential, and the other utilized ferrous iron (as FeCl2)...

Sulfide Control with Cloevis Biofilm Removal Service
Project Scope
A major city in Florida had been experiencing chronic hydrogen sulfide (H2S) odor and corrosion problems at a forcemain discharge manhole and further downstream at a lift station, resulting in community complaints and collection system corrosion. Furthermore, the forcemain was located in the median of a busy roadway...

Supplemental Dissolved Oxygen, Rapid Response, Drum Conversion
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...

Temporary Phenol Oxidation Program to Support a Refinery Aeration Basin Turnaround – Lab Treatability Testing Through Successful Full Scale Implementation – A Case Study
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...

The Cloevis® Biofilm Removal System: Results from Early US Commercial Applications
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...

Treatment of Refinery Wastewater Containing High Concentrations of Chemical Oxygen Demand and Total Sulfides for Low Odor Processing through a Capacity-Challenged Bioreactor
ABSTRACT
Shell Puget Sound Refinery (PSR) is a fully-integrated production facility that first went on stream in September 1958, initially processing up to 45,000 barrels of crude oil per day. Currently, the plant processes up to145,000 barrels (6.1 million gallons) of crude oil per day producing many useful products...
