Polyionic Molecular Diffuser and Filter Method

A method for introducing gas into a fluid, comprising the steps of:

• introducing said gas into a elongate diffuser pipe defined by elongate slots formed longitudinally along a portion of its length, said diffuser pipe located within an outer submersible housing;
• first passing said gas through said elongate slots and into radial gaps formed between a stack of ring-shaped plates surrounding said elongate slots;
• second passing said gas through said radial gaps an into the interior of said submersible housing;
• and
• finally passing said gas through perforations formed in said submersible housing.

A liquid-submersible gas filter, comprising:

• a submersible housing defined by:
• a base plate having an inlet aperture formed therethrough;
• a cannister attached to said base plate to form an internal chamber, said cannister walls defined by a plurality of small apertures formed therethrough;
• a gas diffuser pipe passing through said inlet aperture and into said internal chamber, said gas diffuser pipe formed with a plurality of elongate slots penetrating the wall of said diffuser pipe between the interior of said gas diffuser pipe and the exterior of said gas diffuser pipe, said gas diffuser pipe defining a longitudinal axis and terminating in a threaded distal end inside of said internal chamber;
• three or more thin plates forming a stack defining a planar axis perpendicular to said longitudinal axis, said gas diffuser pipe passing through central apertures in said thin plates of said stack, such that said gas diffuser pipe elongate slots are covered by said stack;
• upper and lower sealing rings atop and below said stack of plates, respectively;
• upper and lower compression plates atop and below said respective sealing rings;
• and
• an end cap engaging said threads at said distal end to compress said stack of thin plates between said compression plates.
