BOD Analyzer – BOD-573

BOD Analyzer – BOD-573

The BOD-573 is a manometric (differential pressure) analyzer used for measuring Biochemical Oxygen Demand (BOD) in water, typically over a 5-day period (BOD55) to assess organic pollution.

It is commonly used in environmental testing and sewage treatment plants, featuring a measurement range of 0–4000 mg/L and the capacity to test six samples simultaneously, with 10-year data storage.

Key Uses of the BOD-573 Analyzer:
Wastewater Analysis: Used to measure the pollution level of organic matter in water by monitoring oxygen consumption by microorganisms.
Process Monitoring: Used to evaluate and optimize the operational efficiency of sewage and wastewater treatment plants.
Environmental Testing: Suitable for testing BOD levels in sewage, industrial waste, and environmental water samples.
BOD5𝟓 Standards: Qualified for determining BOD55
values using glucose-glutamic acid standard solutions.
Long-Term BOD Studies: Allows for customisable culturing times ranging from 1 to 30 days, although 5 days is standard.

Operating Principle & Features:
Manometric Method: Microorganisms in the sample consume oxygen, creating a pressure drop due to the absorption of formed CO2 2 by NaOH, which the machine reads as 𝑚𝑔/𝐿BOD.
Capacity: The device allows simultaneous, direct-reading measurement of six different samples.
Data Management: Capable of storing 10 years of test result values for historical tracking.

A BOD (Biochemical Oxygen Demand) Analyzer measures the amount of dissolved oxygen microorganisms consume to decompose organic matter in water. It is primarily used to determine the organic pollution level in wastewater, treated effluent, and environmental water, ensuring compliance with environmental regulations.

Key Uses and Applications:
Wastewater Treatment Monitoring: Used to evaluate treatment plant efficiency by measuring BOD from influent to effluent.
Environmental Monitoring: Determines the impact of wastewater on oxygen levels in receiving streams, rivers, and lakes.
Regulatory Compliance: Assesses if water discharge meets environmental safety standards.
Water Quality Assessment: Analyzes the pollution strength of water samples in industrial and laboratory settings.
Automated Testing: Modern systems often feature automatic sampling, dilution, and data logging (e.g., using pressure difference methods).

BOD analyzers, such as those from Hach or Mantech, often use a 5-day incubation period (
BOD5 BOD5) at 20∘C20∘C to measure the oxygen consumption, which directly relates to the level of pollution in the water
