PeroxyChem Installs Largest Peracetic Acid Wastewater Disinfection System In The World

Philadelphia, PA /PRNewswire/ - PeroxyChem, a global manufacturer and supplier of peroxygen chemistries, obtained final acceptance from the City of Memphis to start operation of its peracetic acid (PAA) disinfection system at the Maynard C. Stiles Wastewater Treatment Facility in Memphis, Tennessee.

After extensive research and testing, the City of Memphis determined PAA is the most cost-effective disinfection method for the City's wastewater treatment facilities. PeroxyChem worked closely with the City and its consultant, CDM Smith, on the PAA system's design and functional requirements. The system includes storage tanks, chemical feed pumps and a state-of-the-art control system that enables automatic PAA dose adjustment in response to changes in influent water quality parameters.

"Our PAA technology enables wastewater plants to avoid the risks associated with chlorination or the expenses associated with UV. We are pleased to be able to bring our chemistry to Memphis and provide a full solution that meets their specific treatment challenges," said Alberto Garibi, PeroxyChem's Vice President of Water Treatment Technologies.

In addition to the system itself, PeroxyChem is building a production plant adjacent to the Maynard C. Stiles facility that will deliver PAA to the disinfection system via pipeline. This approach brings new investment and creates new jobs, while improving reliability of supply and minimizing operating costs for the City.

"The City of Memphis selected PeroxyChem due to its innovative approach that not only helps us achieve our mission to treat wastewater with the best available technology, but also attract new investment to our City, support local businesses and create new jobs," said Robert Knecht, Director of Public Works.

Construction of the PAA production plant is underway and scheduled to begin operations by the end of 2019.
