Zone of Purification in Filter Media
The zone of purification in filter media refers to the area where bacteria play a crucial role in removing organic matter from water. Bacteria are essential in wastewater treatment processes as they help break down and convert organic compounds into simpler, less harmful substances.
Heterotrophic Bacteria
Heterotrophic bacteria are microorganisms that obtain their energy by decomposing organic matter. In the zone of purification, heterotrophic bacteria are responsible for oxidizing the organic matter completely. This process is known as heterotrophic oxidation.
Role of Heterotrophic Bacteria
Heterotrophic bacteria play a vital role in the purification of water through the following mechanisms:
1. Decomposition: Heterotrophic bacteria decompose complex organic compounds present in the water, such as proteins, carbohydrates, and fats. They break these compounds down into simpler forms.
2. Oxidation: Once the organic compounds are broken down, heterotrophic bacteria oxidize them further, converting them into carbon dioxide (CO2), water (H2O), and other simpler compounds. This oxidation process helps to remove the organic matter from the water.
3. Nutrient Recycling: Heterotrophic bacteria also play a significant role in nutrient recycling. As they decompose organic matter, they release essential nutrients, such as nitrogen and phosphorus, back into the water. These nutrients are then available for other organisms in the ecosystem.
4. Biofilm Formation: Heterotrophic bacteria form a slimy layer called the "schmutzdecke" or biofilm on the surface of the filter media. This biofilm provides a suitable environment for the bacteria to thrive and carry out their purification activities effectively.
Conclusion
In the zone of purification in filter media, heterotrophic bacteria are responsible for oxidizing the organic matter completely. Through decomposition, oxidation, nutrient recycling, and biofilm formation, these bacteria help in removing organic compounds from water, making it safer and cleaner for various applications.
