FAQ

FAQs about Online COD BOD TSS Sensor Analyzer

What is COD, BOD, and TSS?

COD (Chemical Oxygen Demand) measures the oxygen required to chemically oxidize organic and inorganic matter in water — an indicator of the pollution load. BOD (Biochemical Oxygen Demand) is the dissolved oxygen consumed by microorganisms while decomposing organic matter — a key parameter for wastewater treatment effectiveness. TSS (Total Suspended Solids) is the concentration of solid particles suspended in water, important for water clarity and sedimentation assessment.

Why measure Chemical Oxygen Demand (COD)?

COD measurement assesses the organic pollution level of water bodies, monitors wastewater treatment efficiency, ensures compliance with discharge regulations, helps optimize treatment processes, predicts oxygen depletion events, and supports R&D of more sustainable treatment technologies.

What processes require COD monitoring?

Municipal and industrial wastewater treatment (input / treatment / output), treatment of industrial effluents, and drinking water plants — monitoring organic matter in raw water, oxidation, coagulation and activated carbon filtration stages.
