Short summary

TOC (total organics carbon) analysis, as a laboratory and online technology, offers new perspectives to organic measurements in waters and waste water, supplementing regulatory oxygen demand tests. TOC monitoring, implemented as a tool to make informative and rapid treatment decisions, becomes a useful process control parameter. This paper discusses the various technologies available and details how three municipal plants gained insights into their processes and saved on their spending with TOC.
