Measuring biodegradable organic load to evaluate biological treatment performance.
A BOD sensor measures the Biochemical Oxygen Demand of water or wastewater, which represents the amount of oxygen required by microorganisms to biologically decompose organic matter. BOD is a key indicator of biodegradable pollution load.
Online BOD sensors estimate biodegradable organic content by correlating oxygen consumption, microbial activity, or optical signals with laboratory BOD values. These measurements provide near-real-time insights compared to traditional multi-day lab tests.
The measured value directly represents the estimated biodegradable organic load in a liquid.
BOD trends indirectly indicate treatment plant health, microbial activity balance, organic shock loads, and the effectiveness of biological processes.
With Industrial IoT integration, BOD sensors enable real-time biological load tracking, proactive aeration control, early detection of process upsets, and compliance-focused wastewater management.
The BOD Sensor reveals how nature responds to pollution. By measuring biodegradable demand, it guides effective biological treatment, safeguards receiving waters, and supports sustainable industrial discharge.
