    Abstract: Gas diffusion elements, formed of a body of solid particles which has been shaped, pressed and rendered coherent by bonding or sintering in a compacted form having pores, and having an enhanced apparent volumetric compression ratio in a central zone thereof, are disclosed. Such elements have a generally horizontal portion including an upper gas discharge surface having a bubble release pressure in water, by a test disclosed herein, in the range of about 2 to about 20 inches of water. Among the preferred embodiments is an element whose gas discharge surface has the property that its coefficient of variation is not greater than about 0.25, based on the values of bubble release pressure at a plurality of points over said surface. Such elements may provide improved gas, e.g. oxygen, transfer efficiency, and therefore hold promise of improving the efficiency and economics of gas transfer processes, such as for instance treatment of sewage or other waste water with air, oxygen and/or ozone.

    Abstract: A floating fine-bubble aeration system for dissolving a gas in a liquid in which the system is floated. A grid of uniformly spaced fine-bubble diffusers is used to establish large area of bubble-laden liquid, having a substantially uniform density. The uniform density prevents the formation of any upwardly directed currents within the interior portion of the area. Bubble residence time is maximized, due to the absence of the currents, thus increasing the efficiency of dissolving the gas in the liquid.

    Abstract: Cleaning of multi-pore diffusion elements in place with cleaning gases while submerged in liquid media by applying said elements in improved gas cleaning apparatus. Such apparatus may for example include diffusion element retaining rings or other retaining devices, positioned at the peripheries of the respective elements, for securing them in gas-tight relationship with their respective plenums for preventing escape of treating and cleaning gas. Another aspect of the apparatus includes diffusers having diffusion elements with upper and lower surfaces bounded by porous peripheral sides, said diffusers also including apparatus for preventing escape of air through the element sides. In another embodiment of diffusers with diffusion elements having upper and lower surfaces bounded by peripheral sides, there are plenums comprising gas tight enclosures that enclose these lower surfaces and that include upstanding walls facing and adjacent to said sides. In yet another embodiment, upward force exerted on diffusion elements by treating gas under pressure is employed to force the elements upwardly against peripheral sealing members and overlying members of peripheral retainers to increase the sealing integrity of the sealing members.
