Overview of diffuser geometry

Overview of diffuser geometry

A nano-bubble type air diffusion system (spec available for highly integrated configuration) is a new type of air diffusion system that achieves energy saving, space saving and high flow dynamic property in a tank by reducing the power spent on operations through enhanced oxygen transfer efficiency and highly efficient configuration by component downsizing.

  • Product compliant with construction technology review (sewage technology) No. 0926

Characteristics

Improvement of oxygen transfer efficiency

An enhancement of oxygen transfer efficiency has been achieved by an increase aeration area through highly integrated configuration of air diffusion plates.

Highly integrated configuration of air diffusion plate holder

For more efficient usage of space, an increase in the amount of flat space has been achieved by eliminating dead space on the projected area.

Increase of area for effective bubble generation in air diffusion plates

By eliminating airtight areas around the air diffusion plate, the area for effective bubble generation has been increased.

Enhanced flow dynamic property in tank

Flow dynamics in the tank are improved by adopting a semi-spherical bottom for the air diffusion plate holder. An improvement has been made also to the carrier to realize a smoother flow.
