The Dubble Disc Diffuser system is one of the world’s most widely-installed fine-bubble aeration systems, available in four alternative diffuser models. Preassembled diffuser elements enable fast and easy installation. Retrofits are available to increase aeration efficiency. All Dubble Disc Diffusers have a built-in non-return valve which provides additional safety to the treatment process by preventing sludge infiltration into the aeration piping system when the airflow is interrupted. The diffusers are interchangeable for retrofits, offering high flexibility. Retrievable grids: What type of diffuser is best for a retrievable grid system? Though some retrievable grids use disc diffusers, most of them use tube diffusers. The neutral buoyancy of tube diffusers makes them valuable in this case — the buoyancy of disc diffusers can cause them to bounce or “dance” in the tank because the grid is not permanently secured. Ballast weight can help, but using tube diffusers helps avoid the extra time and cost of installing them — and retrievable grids typically require sturdy stainless steel, which makes tube diffusers a natural choice. Should you use disc or tube diffusers for wastewater treatment? When you’re considering disc or tube diffusers, determine the highest priorities for your plant. If low maintenance and a long lifespan are a priority and you have shallower tanks or plan to use fixed systems, disc diffusers may be the best option. Alternatively, if you plan to use retrievable systems or have deeper, narrower tanks, tube diffusers may provide more benefits.
Cons of Tube Diffusers:
Some of the disadvantages of tube diffusers include the following:
Higher maintenance needs: Tube diffusers typically require higher levels of maintenance than disc diffusers, though using membranes with a protective coating like PTFE can help reduce maintenance requirements.
Shorter lifespans: Tube diffusers tend not to last as long as disc diffusers, though using membranes with a protective coating can help tube diffusers last longer, as well.
Higher likelihood of catastrophic failure: Because tube diffusers have larger orifices than disc diffusers, the likelihood of catastrophic failure increases. If an orifice cracks, the large opening could leak enormous amounts of oxygen. However, the use of fine-bubble tube diffusers can help decrease this risk.
Less oxygen transfer efficiency: The larger bubbles often produced from tube diffusers lead to reduced oxygen transfer efficiency. However, the use of fine-bubble tube diffusers can help diminish this disadvantage.
Minimal benefits with fixed systems and shallow tanks: Tube diffusers don’t offer particular benefits for fixed systems or shallow tanks, though they have strengths for other systems.
