1-7. Examples of application
- Prevention of sludge accumulation : Cone type
- For regulating the optimum DO : Possible to assemble and disassemble.
- Generation of uniform microscopic bubbles: Maximize the particle transport efficiency.
- Prevention of bubbles unification phenomenon : Triangular pitch method
- Minimum pressure load : Reduction of operating cost
- Air fluxes with a wide range : Multipurpose.
- Stable bubbles : Minimize to separate microorganism.

1-6. Energy saving effects
- Establishing height: Establish it horizontally at the height range of 150 to 500mm from the floor surface in each of the tanks.
- Establishing interval: 400 to 1000mm (Standard interval: 500mm)
- Establishing method: Establish it by connecting to a supply pipe or an integrating pipe with the equal interval sockets.
- Standard establishing numbers: (Width/500-1) x (Length/500-1) - 5000mm W x 10000mm L x 5000 mm H: (10-1) x (20-1) = 171 EA
- After establishing those with an equal interval constantly, correct the operating conditions to correspond with the required dissolved oxygen.

The UFO diffuser is extensively used in water purification plants, sewage and waste water treatment plants, septic tanks for sewage, and the like, taking advantage of the excellent
oxygen transport ratio (20.2%) and the excellent agitating function since it is a uniform bubble generation type for the whole surface of the triangular pitch method and the energy
saving effect caused by a low pressure drop. In addition, it transfers oxygen.
