ENGINEERED AERATION

The fine bubbles produced from the pores promote oxygen transfer though their higher collective surface area of air-water interface compared to coarse bubble systems; diffusing more air into the wastewater as a result.

The low buoyancy of fine bubbles also contribute to the high oxygen transfer. A slow rise to the surface allows more oxygen to transfer from the bubble, and to dissolve into the water at all levels before reaching the surface.

Fine bubble diffuser configurations are designed to be highly efficient; it provides 6–7 lb/O² hp-h, making it 40–60% more energy efficient than coarse bubble or other types of aeration systems.

Use SiteWorks for your complete single-source easy installation and upgrade to fine bubble aeration from any other system type.

COARSE BUBBLE AERATION

More mixing, less maintenance.

3

Coarse bubble diffuser systems offer low-maintenance mixing.

Where oxygen transfer isn’t your limiting factor, EDI’s full-range of CoarsAir* coarse bubble diffuser platforms provide mechanical reliability, application flexibility, and ease of installation and maintenance.

The primary advantage of this technology is its robust design and ability to mix heavy concentrations of solids. There are no moving parts in the water and the large bubble orifices can be less prone to clogging; making this a robust solution for difficult aeration/mixing applications

Coarse bubble diffusers get their name from the type of bubble they produce, i.e. greater than 4mmØ bubbles. The diffusers are attached to a PVC or stainless steel air supply line fixed to the bottom of the treatment basin or tank. When large bubbles are released at the bottom, water is pulled toward the surface along with the large bubbles mixing the wastewater in the basin or tank.
