Why Reagent-less UV-Vis Analyzers Are Changing COD/BOD Monitoring

Continuous compliance monitoring at STPs, ETPs and CETPs has traditionally relied on reagent-based analyzers — accurate, but with an ongoing cost and waste-disposal burden that adds up fast across a multi-parameter installation.

UV-Vis spectroscopy analyzers measure COD, BOD, TOC and TSS optically across a 200–750 nm range using a double-beam design for stability, removing the need for reagents entirely for most organic-load parameters.

For plant operators, that translates into lower operating cost, less hazardous waste, and fewer manual interventions — while a 7-inch touchscreen and Modbus/4-20 mA output keep the analyzer easy to integrate into existing SCADA systems.

If you are scoping a new CETP or upgrading ageing lab-based sampling, our team can help you match the right parameter set and range to your discharge consent limits — reach out via our configurator or contact page.
