Biological Oxygen Demand (BOD) Analyzers for Wastewater Treatment and Water Quality Monitoring

Biological Oxygen Demand (BOD) analyzers play a critical role in evaluating the level of organic pollution in water. By measuring the oxygen consumed by microorganisms breaking down organic matter, BOD analysis helps determine the effectiveness of wastewater treatment, ensure environmental compliance, and protect aquatic ecosystems. These analyzers are used widely across municipal treatment plants, industrial facilities, and environmental monitoring agencies. For B2B clients throughout North America, Water Quality Instruments delivers reliable BOD analysis solutions that are designed for precision, automation, and seamless integration into operational systems. Our analyzers support both standard laboratory procedures and continuous online monitoring to meet diverse regulatory and process control needs.

GAO Case Studies

Vancouver, BC (Canada)

An environmental consultancy used portable BOD analyzers during a multi-season water quality study of a freshwater lake impacted by agricultural runoff. Continuous sampling helped identify seasonal pollution patterns and inform future remediation plans.

USA – Fort Collins, Colorado

An industrial food processing plant implemented automated lab-based BOD testing to reduce regulatory reporting delays. Automation increased testing throughput while maintaining full compliance with EPA standards

Tampa, FL (USA)

A regional water utility deployed multiparameter sondes across major intake channels to monitor seasonal changes in nutrient loads and turbidity. Real-time data helped optimize filtration performance and chemical dosing, reducing treatment costs and improving water clarity.
