| Abstract |
There has been increasing interest in fine pore aeration systems, along with concern about diffuser fouling and the subsequent loss of aeration efficiency. The objective of the study was to assess the relative fouling tendency of fine bubble diffusers at nine activated sludge treatment plants. A secondary objective was to relate fouling to mixed liquor and process parameters. A standardized diffuser test header containing four removable diffusers was installed at each of the participating plants. Diffusers were periodically removed and tested for oxygen transfer efficiency (OTE), bubble release vacuum (BRV), dynamic wet pressure (DWP), foulant accumulation, and increase in OTE after acid cleaning. |
