    As many power plants continue to struggle with the critical last step in their coal ash remediation processes – the final testing phase – some plants have successfully adopted the use of recently advanced sensor technology to measure real-time total suspended solids (TSS) to verify their discharge water is meeting specified requirements.

    Having the ability to monitor TSS real time, and obtain accurate results that are repeatable and verifiable with random lab tests, allows for users to automate functions such as controlling pumps transporting effluent, or start and stop pretreatment processes designed to keep effluent within permit guidelines.
