MODERATE OXYGEN TRANSFER EFFICIENCY, LOW MAINTENANCE, MAXIMUM MIXING

EDI’s full spectrum of coarse bubble diffuser platforms provide advances in mechanical reliability, application flexibility, and ease of installation and maintenance.

The primary advantage of this technology is its robust design and ability to mix. First, the circulation and turbulence created by the static tube ensures that the entire water column is mixed adequately and sludge accumulation is limited. Second, the fact that there are no moving parts in the water and the orifices are less prone to clogging makes this a very robust solution.

Otherwise known as large bubble diffusers, coarse bubble diffusers get their name from the type of bubble they produce. Coarse bubble diffused systems are composed of dozens to hundreds of coarse bubble diffusers, each attached to a PVC or stainless steel air supply line fixed to the bottom of the treatment basin or tank. The most common coarse bubble aerator is known as a static tube. When large bubbles are released at the bottom of the tube, they create an effect that pulls the water from below the static tube and pushes it towards the surface.
