ABSTRACT:
A large area sparger has a gas-permeable diffuser bonded to a gas-impermeable underlying element so that inflowing gas is distributed throughout a gap between the sparger and the underlying element. Bonding regions interconnect the diffuser and the underlying element around the sparger perimeter and throughout a gap region within the perimeter in a pattern that keeps the diffuser flat during operation and allows gas to flow around the bonding regions to reach all of the unbonded area of the diffuser. By giving the diffuser a liquid interface surface with a high surface energy, the gas passing through a finely porous diffuser departs from the diffuser interface surface and enters the liquid as very fine bubbles having a large area of contact with the liquid.
