Disinfection Process Optimization in Wastewater Treatment Plants Using VeloCens

The main objective of this project was to add Roshan Water’s rapid bacteria testing capability to wastewater treatment plants’ operations and optimize the disinfection process. Through the collaboration with ARROW Utilities, rapid E.coli test results were used to characterize the UV disinfection system and optimize the process. At the end of this project, it was determined that the treatment plant can reduce its UV dosage by as much as 50%. Today, the treatment plant is using 30% UV dosage which in turns reduces the power consumption of the UV system and the associated GHG emissions by 30% annually.
