What is BOD?
Biochemical Oxygen Demand (BOD) is a key parameter for measuring water quality and quantifying the amount of organic matter present. When BOD levels are high, dissolved oxygen is reduced, which can seriously harm aquatic fauna and disrupt ecosystems.
In this article, we discuss the main strategies for reducing BOD in wastewater through physical and biological processes, as well as the use of environmental bacteria as a practical and sustainable alternative.
Main Causes of High BOD
The factors that usually increase BOD are:
-
Organic matter: food scraps, plant residues, and excrement.
-
Chemicals: detergents, grease, oils, and cleaning compounds.
-
Industrial effluents: discharges with a high organic load from sectors such as food, textiles, and paper.
All of these sources intensify the organic load, increasing the
need for oxygen for contaminant degradation.
Biological treatments for BOD reduction
Biological treatment is essential to accelerate the degradation of organic matter. The incorporation of specialized bacteria optimizes this process, improves ecosystem balance, and ensures regulatory compliance.
Among the most commonly used options:
- Aerobic treatment: microorganisms that consume organic matter in the presence of oxygen.
- Anaerobic treatment: bacteria that operate without oxygen, generating biogas as a byproduct.
To enhance these systems, the use of solutions such as Novomax WasteWater Treatment Plants is recommended, which provides bacterial strains designed to efficiently reduce BOD in different types of wastewater.
Advantages of reducing BOD
- Improved effluent quality: less organic load in the treated water.
- Regulatory compliance: avoids penalties for exceeding legal limits.
- Odor reduction: less accumulation of putrescible compounds.
- Process optimization: less need for additional treatment and lower costs.
- Environmental protection: preservation of rivers, lagoons, and ecosystems.
