Abstract

Chemical oxygen demand (COD) is a major parameter for wastewater treatment plant design and operation. The analysis takes two to three hours and produces toxic waste that is harmful to aquatic life. The online pollution monitoring system needs the analysis period as less as possible to report the effluent condition. Total organic carbon (TOC) analysis can be replaced with response for requirement of rapid analysis. The study had been done by digestion of total organic carbon to carbon dioxide gas to correlate to the COD in synthetic wastewater. Electro - oxidation system and ultrasonic wave are the tools for TOC breakdown to carbon dioxide. Carbon dioxide gas was monitored by non-dispersive Infra-red (NDIR) type of analyzer. This study has shown that the COD analysis can be replaced by TOC digestion (CO2 * 1.3-2.3 = COD) in 15 minutes.
