Integration of High-Frequency Performance Data for Microbial and Chemical Compounds Control in Potable Reuse Treatment Systems

In direct potable reuse (DPR), the environment (i.e., aquifer or reservoir) does not provide the post-treatment benefits of additional treatment, dilution, and retention time that it provides during indirect potable reuse. Therefore, there is a need for faster response times in DPR systems, imposing the challenge of rapidly evaluating treatment performance. To address this challenge, this project developed a practical blueprint for utilities to implement monitoring and control systems that allow for (1) enhanced integration and visualization of performance data, (2) rapid automation of control process, and (3) improved regulatory transparency.
