Steve will be presenting the findings of ITAs TOC correlation study Addressing BOD5 Limitations through TOC Correlations:  A Five Facility International Investigation.

This presentation will discuss site-specific correlations between 5-day biochemical oxygen demand (BOD5) and total organic carbon (TOC) for five WWTPs representative of various flows, treatment technologies and watershed ecosystems.   

Included in this discussion is a presentation of the current practices of using TOC analysis as an alternative to BOD5 and an examination of  correlation for BOD5 and chemical oxygen demand (COD).

Attendees will learn:

Long-term practices of using TOC as a process control parameter-specifically to monitor the removal of organics in a wastewater treatment process and the utilization of carbon balances;

How a statistically significant  BOD5:TOC correlation can be determined; and

 How to develop a site-specific BOD5:TOC correlation to allow a TOC limit to be substituted for a BOD5 limit in permits.
