Water circulation apparatus system and method

A liquid circulation apparatus for moving liquid from the lower levels of a body of liquid to the upper surface said liquid circulation apparatus comprising:

• a circular dish placed just below the upper surface of said liquid said dish having outer walls with an upper edge and a lower edge, said outer walls tapering down and inward from said upper edge to said lower edge so as to define an upper opening and a lower opening said lower opening having an area substantially less that of said upper opening;
• said circular dish defining at least one freeze flow slot;
• an upper horizontal lip defined by said circular dish's upper edge, said upper lip being substantially parallel to said upper surface of said water;
• an impeller mounted in a horizontal position above said lower opening of said circular dish, said impeller having a diameter at least as great as the diameter of said lower opening;
• and
• a frame section mounted about said circular dish.

A method of creating a circulating flow in a body of liquid having an upper surface and lower levels said method comprising the steps of:

• A. Placing a liquid circulation apparatus in said body of water said liquid circulation apparatus having a circular dish placed just below the upper surface of said liquid said dish having outer walls with an upper edge and a lower edge, said outer walls tapering down and inward from said upper edge to said lower edge so as to define an upper opening and a lower opening, said lower opening having an area substantially less that of said upper opening, said dish being concave upwardly facing;
• B. Drawing liquid from lower levels of said body of liquid to a point near the surface inside of said circular dish on said liquid circulation apparatus through a draft tube connected to said lower opening said draft tube walls extending perpendicularly downward from said lower opening said draft tube further having an impeller said impeller positioned in said dish above said draft tube said impeller having a diameter greater than that of said draft tube or said lower opening;
• C. Supplying said circular dish with an outer horizontal lip;
• D. Distributing said water from said lower levels in a 360 degree manner over said horizontal lip;
• E. Creating an outwardly expanding laminar flow of water from said distribution;
• and
• F. Repeating steps B to E so as to start the water turning in a circular fashion spreading out in all horizontal directions from said liquid circulation apparatus in a given body of liquid.
