The aerobic granular sludge (AGS) is an emerging technology widely spread, since most organic matters in actual domestic sewage were particulate matters, this study aims to determine whether the attachment between micro particles and different sized AGS was influenced by granule surface area. of (2.0-5.0 mm) investigated. Furthermore, simulate broken fragments AGS, complete 4.0-5.0 mm cut into 2,4, 8 pieces, performance pieces similar compared. Fourier transform infrared (FTIR) fluorescence staining applied analyze chemical bonds amyloid-glucan like structure from outside inside. results showed 3.1-4.0 had best area particles, followed 2.5-3.1 AGS. not determined specific area, but closely related roughness caused structure. distribution density decreased inside, if during aeration, preferential be attached outer layer initial granule. little relationship with hydrophilicity surface, either or inner layer. This highlighted crucial role particle attachment, particularly original layer, which facilitate attach contribute form new granules.
