Fine Bubble diffuser systems disperse the diffused gas volume to transfer an equivalent amount of oxygen with typical Bubble Size of 1mm – 2.5mm. Application performance is impacted by mixing and installed diffuser density constraints. In a typical wastewater treatment plant, 50%-70% of the energy is consumed by Aeration. With so much of the energy use in a WWTP concentrated at the aeration system, it is a logical target for energy conservation. To employ the most appropriate diffuser, a comparison of performance of various diffuser platforms must be considered in the design. The most important performance values include operating pressure and standard oxygen transfer efficiency (SOTE). This requires rational clean water test results under ASCE or equivalent testing procedures. All the data and calculations in any aeration process optimization process are diffuser platform specific, thus selecting the appropriate type of diffuser (Disc, Tube, Panel) uniquely for each project is very important.
