Dryden Aqua Fine Bubble Air Diffuser

High-Efficiency Aeration for Sustainable Water Treatment

The Dryden Aqua Fine Bubble Air Diffuser is a cutting-edge solution for wastewater treatment, aquaculture, and oxidation processes. Engineered with precision and innovation, it delivers an exceptional oxygen transfer rate of up to 5 kg/kWh, ensuring ecological and cost-efficient water treatment. With a semi-flexible tubular design, internal self-ballast, and optimal airflow efficiency, it’s the ideal choice for wastewater professionals, aquaculture systems, and eco-conscious industries.

Available in nine lengths ranging from 0.3 to 3 meters, this diffuser is perfect for diverse applications, including agricultural wastewater, landfill leachate, and destratifying lakes or reservoirs.


Key Features of the Dryden Aqua Air Diffuser

  • Semi-Flexible Construction
    Combines strength with flexibility to prevent fouling and enable easy cleaning.

  • Self-Ballasted Design
    Eliminates the need for external anchors; easy to install and reposition.

  • Outstanding Oxygen Transfer Efficiency
    With an oxygen transfer rate of up to 5 kg/kWh, the diffuser outperforms traditional systems.

  • Durability in Challenging Conditions
    Resistant to calcification, with a lifespan exceeding 10 years, even in chemically aggressive wastewater environments.

  • Wide Airflow Range
    Capable of handling 1–10 m³/h of air with a pressure differential of less than 0.2 Bar.

  • Low Maintenance
    Easily cleaned and serviced without system shutdowns or water emptying.


Applications of the Fine Bubble Air Diffuser

  • Wastewater Treatment
    For industrial, municipal, and agricultural wastewater, the diffuser optimizes biological processes to reduce BOD and COD efficiently.

  • Aquaculture Systems
    Maintains high oxygen levels, critical for the health of fish and shrimps, and reduces disease risks.

  • Oxidation Processes
    Facilitates the removal of ferric, manganese, and arsenic in contaminated water.

  • THM and VOC Gas Stripping
    Removes harmful gases, including trihalomethanes and radon, in water treatment facilities.

  • Destratification of Lakes and Reservoirs
    Alleviates algae blooms and improves nutrient circulation with reliable aeration.

  • Agricultural Wastewater
    Ideal for handling high-load wastes from livestock, like pigs and cattle.

Advantages Over Other Air Diffusers

  • Surface Aerators waste energy with low oxygen transfer (1–2 kg O₂/kWh). The Dryden Aqua Diffuser outclasses them with up to 5 kg O₂/kWh.

  • Flexible Membrane Diffusers require heavy frames and are prone to fouling. The Dryden Aqua unit avoids these pitfalls with its hybrid, self-ballasted design.

  • Minimal Maintenance Costs and no chemical agents needed for cleaning, making it ideal for long-term operations.


Installation Instructions

The diffuser is designed for easy installation and operation. Simply connect it to a ½” flexible hose linked to an air distribution ring main. Drop the diffuser into the reservoir or lagoon, and it’s ready to go. Maintenance can be performed while the system is running, ensuring downtime is minimized. A wide choice of compressors (diaphragm, rotary vanes, or screw compressors) can be used, depending on the water depth and air pressure requirements.


Why Choose the Dryden Aqua Air Diffuser?

  1. Proven Performance
    Independent tests demonstrate its efficiency at 29% compared to 14% for membrane diffusers.

  2. Eco-Friendly Solution
    Reduces energy use and chemical dependency for sustainable water treatment.

  3. Long Operational Life
    Engineered to withstand even the harshest environments, this diffuser ensures optimal operation for over a decade.
