A mechanism for the role of shear during aerobic granulation was proposed. The mechanism suggests that shear acts to reduce granule surface fouling. Surface fouling from rapidly growing aerobic microorganisms was examined. Granulation occurred under low shear only when there was low potential for fouling.
