Biological Oxygen Demand Detection Service

Accurate Biological Oxygen Demand (BOD) Analysis at Creative Biolabs

Anaerobic digestion is an effective tool for generating renewable energy. BOD testing is required to screen suitable Biomass feedstock and optimize anaerobic digestion process optimization. At Creative Biolabs, we offer a reliable and accurate BOD testing service according to our extensive experience and specialized equipment. The analysis of BOD provides a measure of the biodegradable organic matter in the sample and the overall efficiency of the Anaerobic Digestion.

The BOD test involves detecting the value of the amount of dissolved oxygen (DO) required to sustain the growth of aerobic microorganisms in a sample over five days. This process needs to be carried out at specific temperatures, under sealed and dark conditions to avoid the generation of DO. The final BOD is obtained from the difference in DO as well as the start and end times of the diluted incubation. The assay procedure is as follows:

Upon receipt of the sample, we first screen the sample for chlorine to add microbial populations for testing.
A mixture of samples, sterile buffered dilution water, and microbial populations are placed in a dark environment for 5 days and the initial DO is tested.
The final oxygen concentration is tested and BOD is calculated.

Published data

BOD is one of the indicators to quantitatively assess the anaerobic digestion process and to measure the biodegradable organic matter in the samples. The ratio of BOD to COD is used to indicate the biodegradable fraction of the waste. This paper describes the methodology, process, and application for measuring BOD. The detection of BOD needs to be done under dark conditions to avoid the production of dissolved oxygen through photosynthesis. Ultimately, BOD is determined by the difference between the final and initial dissolved oxygen. This paper also describes a BOD variant, carbonaceous BOD. The difference between carbonaceous BOD and BOD detection is the addition of nitrification inhibitors. Carbonaceous BOD can more accurately measure organic matter and can be used in the detection of aerobic digestion of wastewater. The understanding of the methods and significance of these parameter tests helps us to better study and optimize the anaerobic digestion process.^{1, 2}

FAQs

Q1: What is the difference between BOD and COD?

A1: BOD and COD are both used in wastewater treatment, environmental testing, and anaerobic digestion, but there are differences in how they are measured and what they are tested for. COD is calculated in a few hours by using dichromate reflux. BOD tests take longer and rely on bacteria to oxidize biodegradable organic matter in the sample.

Q2: What are the applications of BOD testing?

A2: BOD testing has applications in a variety of fields such as environmental testing and wastewater treatment.

Wastewater treatment: The efficiency of the wastewater treatment process is determined by BOD analysis, which helps to adjust wastewater treatment parameters and optimize performance.
Anaerobic digestion process optimization: BOD testing is used to assess the efficiency of anaerobic digestion to ensure stable and efficient biogas production.
Environmental monitoring: BOD testing is used in environmental monitoring to assess the health of rivers and other bodies of water.
