An air-powered water circulation system for ponds, lakes, municipal water tanks, and other bodies of water having a draft tube extending along and about a vertical axis between upper and lower end portions and supported by a flotation arrangement with the upper end portion slightly below the water surface. A pneumatic, air flow arrangement is then provided to supply pressurized air from an air pump to a plurality of submerged air pipes positioned within the draft tube below the upper end portion thereof and extending inwardly from a submerged manifold toward the interior of the draft tube. In operation, pressurized air is supplied from the air pump through an air delivery conduit to the submerged air manifold and into the submerged air pipes where it is discharged as air bubbles through series of discharge holes extending along the pipes to create an overall circulation pattern in the body of water.
A submersible, water circulation system for enclosed tanks such as used by municipalities, fire districts, and industries. The system includes a driving unit having a shell extending along an axis with a pump supported within the shell. The shell has at least one inlet and at least one outlet and is positionable on the floor of the tank with the outlet facing upwardly. The upwardly facing outlet is preferably a thin, upwardly facing, elongated slot that creates a thin, substantially planar discharge of water therethrough that is directed upwardly toward the surface of the body of water. The substantially planar discharge presents a very large surface area for its volume and induces water adjacent the outside of the shell of the driving unit to move upwardly with it toward the surface of the body of water.

COLLAPSIBLE WATER CIRCULATION SYSTEM FOR ENCLOSED TANKS
A collapsible water circulation system (1 ) for enclosed tanks (2) such as used by municipalities. The system (1 ) in its collapsed configuration is designed to fit through the opening (9) in the tank (2) and then to expand to its extended configuration without personnel having to enter the tank (2) The system (1 ) Includes a tube (11 ) extending from a dish (13) to an inlet (H') anchored on the tank floor (7) The system (1) also includes at least three flotation arms (21) that can be deployed to extend horizontally and outwardly (13) An impeller (15) within the dish (13) draws water from the inlet (1 V) through the tube (11) to the dish (13). The water passes through the dish (13) over its upper lip (13') and radially. The flotation arms (21) mount to the system (1) above the dish (13) and can pivot between collapsed and deployed positions
A circulation system (1) for bodies of water (2). In one set of embodiments for larger bodies of water, modified horizontal plate designs (20, 20') are provided at the entrance (7) of the draft hose (5). The plate designs have sections (22, 22') that pivot downwardly as the flotation platform (3) and depending draft hose (5) are rapidly raised in high wave conditions to let the water escape downwardly out of the hose (5). Adaptations to the floats (9) for the elongated arms (31) of the platform (3) are also made to essentially eliminate the creation of any damaging torques on them from high waves. Another set of embodiments are particularly adapted for smaller systems in municipal water tanks (41) for thorough mixing of the water (2) and treatment to kill undesirable ammonia oxidizing bacteria and prevent or at least inhibit their return.
Circulation systems for ponds, lakes, or other bodies of water using a flotation platform (3), dish (19), and impeller (21). One embodiment has a connecting arrangement (100) between the drive motor (17) and the impeller (21) that permits the two to be easily and quickly coupled and uncoupled. The connecting arrangement (100) also is designed to accommodate slight misalignments between the shafts (17',21') of the drive motor (17) and impeller (21). An arrangement (130) to adjust and calibrate the depth of the inlet (7) to the draft tube (5) is disclosed. The system further includes solar panels (15,15') that can be pivotally swung outwardly to open positions, angularly adjusted about a horizontal axis (152), and mounted to face toward the central axis (13) of the flotation platform (3) rather than away from it. Arrangements are further provided to monitor and control the components of the system (1") including remotely from shore.
