Abstract
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.

33. 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; and
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. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42)

58. A method for sparging a fluid with a gas, the method comprising:
-
dispensing a fluid into a chamber of a container; and
delivering a gas to a sparger coupled to the container or disposed within the chamber of the container such that the gas permeates through a sparging sheet of the sparger that is comprised of a flexible sheet of a gas permeable nonwoven fabric. - View Dependent Claims (59, 60, 61, 62, 63)
