  • AQUATEC® Tube Diffusers is designed high oxygen transfer efficiency.

  • High oxygen transfer efficiency

    Large numbers of small bubbles will transfer far more oxygen than a small number of large bubbles due to the increase in total bubble surface area. AQUATEC® Tube Diffusers generate smaller bubbles than those coming from holes drilled in pipe. Therefore, when using diffusers you can achieve a desired amount of oxygen transfer with less air (less energy demand). This means lower blower operating speeds and lower energy costs. This is especially true if you incorporate smaller bubble diffusers into your system.

    Added value

    - High oxygen transfer efficiency (OTE) up to 5.5 kg/kWh
    - Maintains higher dissolved oxygen (DO) levels
    - Reduces energy costs by up to 75%
    - Excellent mechanical and chemical properties compared to silicone and EPDM
    - Low replacement cost

  • Clogging Issues

    While drilling holes in pipes seems like a simple, pragmatic option, diffusers are designed to help keep the contents of your tank from entering your air supply lines and prevent clogging when the blower is not operating. The membranes on fine bubble diffusers contract and serve as a check valve when air pressure is not applied internally.

    Anti-Clogging and Self-cleaning

    Dynamic orifices are more robust than static orifices and do not clog as easily because of their ability to expand and contract. Secondly, since EPDM material is malleable, excellent elastic, smooth surface, it is equipped with a “self-cleaning capability.” By bumping the airflow up a notch, the orifices will expand and expel any surfactants that have begun to build up or clog them. Due to these features and a much lower risk of clogging, dynamic orifices tend to have a much more efficient long term field transfer efficiency than static orifices.

AQUATEC® Tube Diffusers playing in Aquaculture

Since a majority of all aquaculture problems, including disease, are caused by poor water quality and, in turn, most water quality problems can be resolved with proper aeration (oxygenation), it is clear that aeration plays a crucial role in this process. Ussing AQUATEC® aeration system has the following advantages:

 It increases the dissolved oxygen level of the water and prevents oxygen depletion during the night.
 It accelerates the diffusion effect of not only the oxygen, but also enables the capture or release of carbon dioxide. Carbon dioxide is important for culture of algae and therefore for maintenance of appropriate watercolor.
 It facilitates the volatilization of undesirable gases such as N2, NH3, CH4 and H2S.
 It reduces the daily fluctuation range of pH value.
 It accelerates the decomposition and mineralization of organic matter in water and soil and helps in the release of nutritive value of fertilizers.
 It diminishes the possible stratification of pH, DO, salinity and temperature in the pond water.
 It helps in mixing the pond water and maintenance of ideal conditions all over the pond.
 It increases turbidity when necessary.
