AquaSust Disc Diffuser In Biological Nutrient Removal Processes

1. Enhanced Oxygen Transfer

Oxygen transfer efficiency is crucial in BNR processes, particularly during nitrification, which requires a high oxygen supply for the oxidation of ammonia. The fine bubbles produced by the AquaSust disc diffuser ensure that oxygen is effectively dissolved in the water, supporting the metabolic activities of nitrifying bacteria. This efficient oxygenation leads to:

Improved Nitrification Rates: High oxygen availability accelerates the growth and activity of nitrifying bacteria, enhancing the conversion of ammonia to nitrate.

Stable Process Conditions: Uniform aeration prevents the formation of anaerobic zones in the aerobic tank, maintaining optimal conditions for nitrification.

2. Effective Mixing And Preventing Stratification

The uniform distribution of bubbles provided by the AquaSust disc diffuser ensures effective mixing within the treatment tank. This mixing is essential for:

Preventing Stratification: Even distribution of oxygen prevents the formation of oxygen-depleted zones, ensuring that all microorganisms receive the necessary oxygen for their metabolic processes.

Enhanced Contact: Improved mixing enhances the contact between microorganisms and nutrients, promoting efficient nutrient uptake and removal.

3. Energy Savings And Cost Efficiency

The energy-efficient operation of the AquaSust disc diffuser is a significant advantage in BNR processes, where continuous aeration is required. Benefits include:

Reduced Energy Consumption: The fine bubble production and high oxygen transfer efficiency of the AquaSust disc diffuser result in lower energy requirements compared to conventional aeration systems.

Operational Cost Savings: Lower energy consumption translates to reduced operational costs, making the BNR process more cost-effective.
