New Portable Metering System Increases Confidence in Field Measurements

摘要

Operators at the Loveland, CO, wastewater treatment plant have found that precise measurement of dissolved oxygen (DO) concentration is critical in the plant's step-feed aeration process. Operators use hand-held instruments to gather "snapshots" of conditions in the facility's various pro- cesses and to verify the performance of their on-line DO control system. While advanced on-line instrumentation provides continuous measurements for real-time process control, the use of portable hand-held instruments plays a critical role in day-to-day field operations at municipal wastewater treatment plants.
