Abstract

A flexible aeration panel is described, which does not include a rigid support plate. The flexible aeration panel can comprise a first perforated, flexible sheet sealed to a second non- perforated flexible sheet at their peripheral edges, thereby defining one or more cavities that are in fluid communication with at least one gas inlet. The flexible aeration panel can be configured to produce preferably evenly spaced bubbles of gas when positioned in a liquid body. Applications include, but are not limited to, aeration of wastewater, lakes, streams, water basins and the like.

(i) positioning within the liquid body one or more flexible aeration panels, each panel having at least one inlet and at least an upper portion and a lower portion, which portions define at least one cavity that can be filled with a gas under pressure, which pressurized gas flows to each panel and into the at least one cavity via the at least one inlet, the upper portion of each panel being perforated to allow the pressurized gas to escape in the form of bubbles from the upper portion of each panel;
(ii) providing a source of the pressurizcd gas; and (iii) permitting the pressurized gas to flow to each panel and into the at least one cavity via the at least one inlet, whereby the at least upper portion and lower portion of each panel are constructed of one or more flexible, non-rigid elastomeric materials, and wherein one or more flexible panels are positioned within the liquid body by an, anchoring array that permits the leveling of the one or more flexible panels relative to a surface of the liquid body.
2. The method of claim 1 in which the liquid body has a volume substantially greater than that of a bathtub, a hot tub, or a recreational swimming pool.
3. The method of claim 1 in which the one or more flexible, non-rigid elastomeric materials have a density of less than about 1.0 gm/mL.
4. The method of claim 1 in which the panel further comprises a structural frame positioned at or about the periphery of the panel.
5. The method of claim 1 in which the level of the one or more flexible panels is substantially parallel to a surface of the liquid body.

11. A method of distributing a gas through a liquid body comprising:
(i) positioning within the liquid body one or more flexible aeration panels, each panel having at least one inlet and at least an upper portion and a lower portion, which portions define at least one cavity that can be filled with a gas under pressure, which pressurized gas flows to each panel and into the at least one cavity via the at least one inlet, the upper portion of each panel being perforated to allow the pressurized gas to escape from the upper portion of each panel in a manner that provides a substantially uniform, unbroken pattern of gas bubbles over a substantial area thereof;
(ii) providing a source of the pressurized gas; and (iii) permitting the pressurized gas to flow to each panel and into the at least one cavity via the at least one inlet, whereby the at least upper portion and lower portion of each panel are constructed of one or more flexible, non-rigid elastomeric materials, and wherein one or more flexible panels are positioned within the liquid body by an anchoring array that permits the leveling of the one or more flexible panels relative to a surface of the liquid body.
