Efficient microbial activity in biofilters is heavily dependent on both oxygen availability and appropriate nutrient levels. Microorganisms, which play a vital role in the degradation of organic matter within biofilters, require oxygen for aerobic respiration. This process enables them to break down contaminants effectively. Sufficient nutrient levels, such as nitrogen and phosphorus, are also crucial as they support the growth and reproduction of these microorganisms, allowing for a robust community that can process wastewater pollutants efficiently.

In environments where oxygen levels are low or nutrients are insufficient, microbial activity can diminish, leading to less effective treatment of the wastewater. Therefore, ensuring a balanced supply of both oxygen and nutrients is fundamental for maintaining optimal conditions for microbes to thrive and perform their vital functions within the biofilter system.
