1. 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 comprising an annular ring having an inside first end and an outside second end, the inside first end being mounted to the sparging sheet and the outside second end being mounted to the base such that no portion of the sparging sheet is mounted directly to the base, the base being comprised of a substantially non-porous material and the transition member being in the form of a flexible sheet, the transition member being comprised of a different material than the sparging sheet.

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.
