Submerged system and method for removal of undesirable substances from aqueous media

A system for removal of undesirable substances from a body of liquid, comprising:

• an aeration structure constructed of a pipe having a continuously inclined surface configured to provide a continuous interaction of air bubbles against substantially an entire length of the continuously inclined surface while moving toward a top of the body of liquid, the continuously inclined surface being substantially submerged in the body of liquid;
• a bio-film of bacteria disposed on the continuously inclined surface;
• a high surface area-to-volume structure located within the pipe upon which a bio-film of bacteria can be formed;
• a heater located in proximity to the aeration structure configured to provide a warmer environment for the bio-film;
• and
• an aeration system, couplable to an air supply system, configured to release the air bubbles toward a bottom of the continuously inclined surface, such that the air bubbles move along the continuously inclined surface as they rise so as to (i) create a variety of aerobic conditions at the bio-film and (ii) engage the air bubbles in a continuous mixing of a micro climate for the bio-film in response to an orientation of the continuously inclined surface (iii) circulate water bottom to top using air bubble lift.

A system for removal of undesirable substances from a body of liquid, comprising:

• a plurality of aeration structures constructed of a pipe having a continuously inclined surface configured to provide an interaction of air bubbles against a length of the continuously inclined surface while moving toward a top of the body of liquid, the continuously inclined surface being substantially submerged in the body of liquid, wherein substantially the entire continuously inclined surface is at an incline;
• a bio-film of bacteria colonies disposed on the continuously inclined surface used to breakdown organic material;
• a high surface area-to-volume structure located within the pipe upon which a bio-film of bacteria can be formed;
• a circuit channel formed in the body of liquid within which the plurality of aeration structures are located;
• and
• an aeration system, couplable to an air supply system, configured to release the air bubbles on demand toward a bottom side of the continuously inclined surface, such that the air bubbles move along the continuously inclined surface and the high surface-to-volume structure as they rise so as to (i) create a variety of aerobic-anaerobic conditions for the bio-film and (ii) create a bottom-to-top circulation pattern to provide nutrient and air mixing to support a micro climate for the bio-film on exposed surfaces.

A method for removing undesirable substances from a body of liquid, comprising:

• directing a portion of the body of liquid to flow through a circuit channel formed using at least one guidance wall in the body of liquid;
• submerging a plurality of aeration structures constructed of a pipe in the circuit channel, the pipe having a continuously inclined surface in the body of liquid and substantially the entire continuously inclined surface of each aeration structure is at an incline;
• enabling a variety of bio-film bacterial colonies to be disposed on the continuously inclined surfaces and high surface-to-volume structure surfaces located within the pipe;
• releasing air at a defined point on the continuously inclined surface using an aeration system, couplable to an air supply system, such that air bubbles are formed and move along the continuously inclined surface as they rise so as to (i) create a variety of aerobic and anaerobic conditions for the bio-film and (ii) create a bottom-to-top circulation pattern to provide nutrient and air mixing to support a micro climate for the bio-film on exposed surfaces.
