Abstract of BG100952U
The diffuser is used in the biological (aerator) waste water treatment. It ensures optimum oxygen quantity for the development of the microorganism. The diffuser is reliable in operation and has longer operational life. It consists of an elastic membrane(1) which is in the form of a hollow sphere with thicker peripheral part (2), its inner surface (4) forming a ring-like notch (5). In the membrane (1) middle part (7) a pressing flap (8)is machined which, in its upper part, takes the form of a small-height cylinder protruding above it, and in its lower surface (10) it takes the form of a truncated cone. Numerous small slits (11) are machined in the intermediate part (3) fitted along an H-shaped Archimedean spiral in cross section plane. The ring-like notch (5) houses a supporting disc (12) made of plastic in the form a section of a hollow sphere having smooth upper (15)and ribbed lower (16) surface. In the middle part (21) of the supporting disc (12) a hollow conical body (22) is machined containing a central conical hole (23). A union (24) is machined concentrically to the gollow body (22), on the inner surface.5 claims, 4 figures
