The City of Memphis concluded that PAA is the most cost-effective disinfection method for the City’s wastewater treatment facilities after an extensive research and testing.
PeroxyChem said that it has 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 an advanced control system that enables automatic adjustments of the PAA dose in response to the changes in the parameters of influent water quality.
PeroxyChem water treatment technologies vice president Alberto Garibi said: “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.”
Additionally, PeroxyChem is building a production plant adjacent to the Maynard C. Stiles facility that is capable of delivering PAA to the disinfection system via pipeline.
The approach is expected to bring new investment and create new jobs, along with improved reliability of supply and minimize operating costs for the City.
Memphis City public works Director Robert Knecht said: “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.”
Construction of the PAA production plant is under progress and is scheduled to start operations by the end of 2019.
A major player in peroxygen and adjacent chemistries, PeroxyChem employs approximately 550 people throughout the world, with facilities in North America, Europe and Asia.
