ABOUT THE CLIENT
WASTEWATER TREATMENT PLANT IN MEXICO
The wastewater treatment plant in Chihuahua, Mexico – Planta de Tratamiento de Aguas Residuales Sur Chihuahua – consists of a North and South plant which operates with similar processes to treat wastewater. In 2019, the plant initiated an extensive restoration to improve the overall conditions of the wastewater plant, to improve the overall quality and ensure that the demands for sustainability are met.
WHAT THE CLIENT NEEDED
A COMPLEX CUSTOM SOLUTION
The client needed a custom solution to fit their complex requirements for an open channel installation at their wastewater treatment plant.
As part of a restoration to improve the conditions of the plant, Suez Mexico was chosen to help revitalize the technology and procedures. In this process, our open channel UV systems was chosen to improve water quality and reliability, while ensuring a lower environmental impact.
THE SOLUTION
AN UPGRADE FROM CHLORINE TO UV
In order to reduce the risk of improperly treated wastewater discharge, a modernization of both wastewater treatment plants was required. This was done by replacing the gas disinfection chlorine systems with UV disinfection technology, to eliminate the risk of possible chlorine gas leaks and its other harmful related effects.
To disinfect the wastewater at such a large scale, 11 Open Channel UV units with 44 lamp bank modules each was supplied. The UV units will thus contribute to chemical free disinfection, achieved through eliminating the risks associated with chlorine, as well as improving the energy consumption of the processes.
The switch from chlorine to UV is estimated to save 9.583 tons of CO₂ per year.
