Reduction of chloride in wastewater effluent with utilization of Six Sigma

by Bodoh, Michael J..

Abstract (Summary)
The objective of this study was to implement a Six Sigma program on a company's wastewater treatment system to determine if the application of the Six Sigma tools would result in a reduction of the chloride concentration. The review of literature included the history of Six Sigma, the Six Sigma problem solving (DMAIC) process, the current state of environmental regulations, as they relate to chloride concentration, and the current technology for chloride removal. Data was collected from the facilities process owners and SCADA (Shop-floor Collection And Data Acquisition) system. The data was analyzed by a Six Sigma team with incremental changes made to the operation to improve (reduce) the chloride concentration to the facility's wastewater treatment plant. The results demonstrate that Six Sigma can be effective in improving the environmental performance of the wastewater treatment plant by improving the operations that are discharging to the facility. Finally, the study offers some recommendations the facility, and other similar facilities may investigate to further improve (reduce) the chloride concentration in the discharge stream from their facilities.
