TOC, Advancing Beyond BOD and COD
Erin England, GE Power & Water
Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) are the traditional methods of indicating pollution in discharged effluents. These measurements not only cannot provide results quickly enough to allow a plant to modify its treatment process but also have poor reproducibility. As a result, Total Organic Carbon (TOC) is becoming recognized as a more reliable, accurate, and environmentally friendly way to obtain real-time water quality results. Through a review of the definitions of BOD, CBOD (carbonaceous BOD), COD, and TOC, this presentation will explore the similarities and differences in the three analyses, along with the weaknesses and strengths of each. Wastewater regulations from Europe and North America will be reviewed.

Heuristic Algorithms Coupled with On-Line Sensors for the Process Control of Water Used in Manufacturing as an Ingredient Rather than a Commodity
Dan Kroll, Hach
Most food processing and manufacturing facilities utilize municipally supplied water as either an ingredient or in the processing of product. As such, responsibility for quality control has remained with the utility rather than the production plant. The use of chemometrics coupled with common parameter on-line instrumentation has been widely used to detect and classify significant changes in water quality in municipal distributions systems. But, this same set of algorithms can find use in other areas where close control of process or ingredient water is critical.
