ABSTRACT OF THE DISCLOSURE A rotating gas diffuser shears fine gas bubbles from the surface thereof when the diffuser is immersed in a body of liquid and rotated therein. A plurality of plates, each in the form of a section of an annulus with its lateral edges radially positioned with respect to the circular rotating gas diffuser, is supported either on the top or the bottom of the diffuser, or on both, near its perimeter. Each porous plate is carried by a plate holder that has a shape similar to its associated porous plates, and with those plates de- fines a gas plenum having an area substantially equal in extent to, but no greater than, the area of the plates. The lateral edges of the plate holders are releasably secured to first and second radially extending structural sup- port elements of a disk like member. One lateral edge portion of the holder carries connecting tabs that together with complementary openings on the first structural element form a male and female fit capable of being disen- gaged by moving the tabs laterally. The other edge of the plate holder carries a projection releasably securable by screws to the second structural element.
