A sparger includes a body bounding a compartment. A tubular port or tube is coupled with the body. The tubular port or tub bounds a passage that communicates with the compartment of the body. At least a portion of the body includes of a first sparging sheet. The first sparging sheet includes a flexible sheet of a gas permeable material such that a gas passing into the compartment of the body through the passage can exit the compartment by permeating through the first sparging sheet.

A sparger comprising: a base having a tubular member extending therefrom, the tubular member having an interior surface bounding a passage, the base and the tubular member each being comprised of a flexible polymeric material having a durometer on Shore A scale with a value of less than 90; anda sparging sheet comprised of a flexible sheet of a gas permeable material secured to the base. 11. The sparger as recited in claim 10, wherein the base comprises a flange radially outwardly projecting from the tubular member. 12. The sparger as recited in claim 10, wherein the tubular member comprises a port, a stem, or an elongated tube integrally formed with or connected to the base. 13. The sparger as recited in claim 10, wherein the sparging sheet is welded to the base. 14. The sparger as recited in claim 10, further comprising a flexible transition member secured to and extending between the sparging sheet and the base, the transition member being comprised of a different material than the sparging sheet. 15. The sparger as recited in claim 10, wherein the sparging sheet is connected to the base at a location spaced apart from the tubular member so that a compartment is formed between the base and the sparging sheet. 16. The sparger as recited in claim 10, wherein the sparging sheet is comprised of a nonwoven fabric, a solvent cast polymeric film, an open cell foamed polymer sheet, or a perforated polymer sheet. 17. A container assembly comprising: a container having an interior surface bounding a chamber, the chamber being adapted to hold a fluid, the container comprising a bag that is comprised of one or more sheets of flexible polymeric material; anda sparging sheet comprised of a flexible sheet of a gas permeable material secured to the interior surface of the container either directly or through a flexible transition member so that a compartment is formed between the interior surface of the container and the sparging sheet, the sparging sheet being disposed completely within the chamber of the container. 18. The container assembly as recited in claim 17, wherein the bag comprises an open topped liner. 19. The container assembly as recited in claim 17, wherein the container is disposed within a rigid support housing. 20. The container assembly as recited in claim 17, further comprising a tubular port, stem, or tube coupled with the container so that a passage bounded by the tubular port, stem, or tube communicates with the compartment. 21. The container assembly as recited in claim 20, further comprising a check valve coupled with the tubular port, stem, or tube. 22. The container assembly as recited in claim 17, wherein the transition member has a substantially ring shaped configuration that is secured to and extends between the sparging sheet and the interior surface of the container, the transition member being comprised of a different material than the sparging sheet. 23. The container assembly as recited in claim 17, wherein the sparging sheet is comprised of a nonwoven fabric, a solvent cast polymeric film, an open cell foamed polymer sheet, or a perforated polymer sheet. 24. A sparger comprising: a base having a tubular member extending therefrom, the tubular member having an interior surface bounding a passage;a sparging sheet comprised of a flexible sheet of a gas permeable material;a flexible ring shaped first transition member secured to and extending between the sparging sheet and the base, the base being comprised of a substantially non-porous material and the first transition member being in the form of a flexible sheet, the first transition member being comprised of a different material than the sparging sheet; anda ring shaped second transition member secured to and extending between the sparging sheet and the base. 25.
