APPLYING OPERATOR KNOWLEDGE AND PROCESS TOOLS TO OPTIMIZE THE CORNWALL WWTP
Abstract:Tools are available to provide a detailed evaluation of a facility and devise ways to optimize its performance. This work applies a detailed process review to an enhanced primary facility to determine a means to improve its performance towards a long-term goal of full secondary treatment or equivalent. The approach of optimizing the existing facility, followed by selective upgrades and implementation of full secondary treatment, was deemed to be the most cost effective route. The project included a detailed process review and a series of operator input workshops as an effective approach to meet the project goals. Optimization of the existing facility was used as a basis for determining the needs for the secondary treatment process upgrade.
The findings demonstrated that the plant is currently performing very well and has optimized most unit processes and that there is the potential for enhancements including clarifier baffle modifications and the economical use of UV disinfection. Many secondary treatment options are available; however, a biological aerated filter process was deemed to have the most advantages for this site.
