BACKGROUND
BOD is a time-sensitive and mission critical compliance and operational parameter for the Orange County Sanitation District (OC San). OC San's NPDES permit includes five effluent limitations on BOD and requires daily monitoring. The BOD system is also used to support Operations for process monitoring and the Resource Protection Division's activities such as source control. Annually, OC San analyzes more than 9,000 samples for BOD from 21 locations throughout Plant Nos.1 and 2 and over 500 industries in OC San's service area.
This new BOD system will allow for quicker turnaround of results from the BOD estimator, from 3 hours to 10 minutes, allowing laboratory analysts to quickly make informed decisions on BOD analysis. In addition, this system will eliminate the generation of hazardous waste while maintaining a high throughput of daily samples necessary to meet NPDES permit requirements and provide support to Operations and Resource Protection Divisions.
RELEVANT STANDARDS
* Commitment to safety & reducing risk in all operations
* Comply with environmental permit requirements
* Ensure the public's money is wisely spent
* 24/7/365 treatment plant reliability
PROBLEM
BOD testing is a daily NPDES permit requirement, and a critical parameter to measure for the OC San Operations (for process monitoring and optimization) and Resource Protection (for monitoring permitted industries) Divisions.
