Monitoring for Reliability and Process Control of Potable Reuse Applications Using On-Line Sensors
To ensure efficacy of advanced treatment of reclaimed water prior to potable reuse, water quality must be evaluated in real-time to verify that the barriers are operating as designed, and also reassure communities that there are no adverse public health hazards from using reclaimed water for potable reuse. Utilities rely heavily on sensors for turbidity, conductivity and total organic carbon to act as real-time triggers to alert operators of treatment failure. These sensors could usefully be augmented by an on-line fluorescence sensor, and a real-time assay for microbial contaminants. While on-line sensors have been demonstrated as highly useful for real-time water quality monitoring, there are several issues and gaps in sensor technology that need to be addressed that will be discussed in this webcast, along with other results from WateReuse Research Foundation project 11-01.
