Bioremediation is used in wastewater treatment for several reasons. This technique use the natural ability of microorganisms to break down organic pollutants and other substances in wastewater. Here are some reasons why bioremediation is used in wastewater treatment:

1. Breakdown of Organic Substances: 

  • Bioremediation is effective in breaking down organic substances, such as fats, oils, and other organic compounds present in wastewater. Microorganisms metabolize these substances and transform them into less harmful or non-toxic substances.

2. Reduction of Chemical Usage: 

  • By using bioremediation, there is a reduced need for chemical treatments in wastewater treatment. Biological processes are employed instead of or in combination with chemical methods, which can be more environmentally friendly.

3. Low Energy Consumption: 

  • Bioremediation often requires less energy compared to some conventional wastewater treatment systems. Biological processes are driven by the natural activity of microorganisms and do not always require as much energy as other techniques.

4. Ecologically Sustainable: 

  • Bioremediation is an ecologically sustainable method as it relies on natural biological processes. It is less dependent on chemical additives and is less harmful to the surrounding environment.

5. Breakdown of Nitrogen Compounds: 

  • Biological processes within bioremediation can help break down nitrogen compounds in wastewater, which is crucial to prevent eutrophication in water bodies where wastewater is discharged.

6. Reduction of Load on Treatment Plants: 

  • By using bioremediation, the overall load on wastewater treatment plants can be reduced. Microorganisms employed in biological processes can help break down pollutants and facilitate subsequent treatment stages.

7. Low Maintenance Requirements: 

  • Bioremediation systems sometimes have lower maintenance requirements compared to more complex treatment methods. This can result in lower operating costs and easier management of wastewater treatment.

Bioremediation means in wastewater treatment to take advantage of its efficiency in breaking down organic compounds and other pollutants in a way that is ecologically sustainable and environmentally friendly.
