Solids concentration is an essential parameter used to monitor and control wastewater processes. The measurements are typically performed on grab or composite samples in the laboratory and data is available the next day. Improvements in online TS analyzer reliability has provided the opportunity to monitor and control wastewater treatment processes in real-time. Plant wide real-time TS monitoring along with other key instruments can be used as an effective way to optimize processes, reduce O&M cost and avoid or delay large capital expenditure. However, it is important to acknowledge that instrumentation needs to be maintained and data output needs to be validated before using it for process control. This paper presents how the San Francisco Oceanside plant staff developed and used these tools to ultimately achieve 13% reduction in energy consumption while improving process performance and reducing other O&M requirements.
