Coal Ash Pre-treatment discharge permits water water quality dewatering water treatment

When state regulators issued new discharge permits for a major power utility’s ash basin, the remote location and its lack of permanent
power made it extremely challenging to comply. The utility needed a system that could remove water from an ash basin where precipitation continued to enter, as well as meet the new water quality requirements for TSS and PH. A dewatering system that offered pre-treatment was needed to maintain water quality until a full-scale water treatment facility was required. This system had to be able to monitor several variables such as pond level, TSS, and PH limits, and daily discharge limits. In addition, the entire system had to be fully automated and monitored continuously during operation with data recorded automatically and retained for record keeping requirements.
