Enhancing Environmental Monitoring Using Total Organic Carbon (TOC)

The biochemical oxygen demand (BOD) test is a widely accepted parameter by regulators for characterizing water quality. However, there is evidence that this test is inaccurate, unreliable, not effective at low concentrations and cannot be used for process control. Regulations allow chemical oxygen demand (COD) or total organic carbon (TOC) to be substituted for BOD5 when long term BOD:COD or BOD:TOC correlation has been demonstrated. This research project aims at the development of long-term correlations of BOD5 and COD to TOC, in accordance with regulatory requirements for wastewater treatment plants representative of various flows, treatment technologies and watershed ecosystems. In this presentation, the most significant data and findings gathered to date will be discussed.
