A field trial of an online Total Organic Carbon (TOC) analyzer was conducted at a municipal wastewater treatment plant to determine if it could be used to detect a breakthrough of supplemental carbon used for denitrification. The field trial concluded that background TOC concentrations were steady enough and low enough to discern a bleed-through of supplemental carbon. In other words, the “background noise level” of TOC was low enough to detect an overfeed of chemical. The TOC analyzer detected supplemental carbon in a challenge test with spiked samples. Different chemicals resulted in different responses. The analyzer used in the test appeared rugged and durable enough to be installed in a controlled environment at a municipal wastewater treatment plant.
