- Aerobic Oxidation: Bioglas facilitates aerobic oxidation, where microorganisms utilize oxygen to break down pollutants. This process is particularly effective for removing organic matter, nitrogen, and phosphorus.
- Anaerobic Oxidation: Under specific conditions, anaerobic oxidation can also occur, where microorganisms break down pollutants without the presence of oxygen. This process is often employed for the removal of certain pollutants like sulfides and heavy metals.
1.3 Enhanced Nutrient Removal:
- Bioglas promotes the removal of nutrients like nitrogen and phosphorus, which can contribute to harmful algal blooms and eutrophication.
- Microorganisms within the biofilm utilize these nutrients for growth and metabolism, effectively removing them from the wastewater stream.
1.4 Bioaugmentation:
- Bioaugmentation involves the addition of specific microorganisms to the Bioglas system to enhance the degradation of targeted pollutants.
- This technique is particularly useful for treating industrial wastewater containing difficult-to-degrade substances.
1.5 Key Advantages of Bioglas Techniques:
- Increased Biological Activity: The large surface area and unique structure of Bioglas maximizes the number of microorganisms that can colonize the material, resulting in enhanced biological activity.
- Improved Treatment Efficiency: Bioglas's ability to support robust biofilms translates into faster and more efficient removal of pollutants.
- Reduced Sludge Production: Bioglas promotes the breakdown of organic matter, resulting in a reduction in sludge volume and the need for costly disposal.
