摘要:
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 and 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.
摘要:
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 aft 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.

摘要:
Method and apparatus for treating potable water in municipal and similar tanks to reduce and remove undesirable disinfectant byproducts such as trihalomethanes from the water by providing a water circulation system to create circulation patterns in the tank water and an air flow system for creating an air flow pattern in the headspace region of the enclosed tank above the water surface. In operation, a portion of the tank water is drawn-up a draft tube from the tank floor to above the water surface and sprayed through a nozzle outwardly about a vertical axis and slightly downwardly toward the surface of remaining tank water. The air flow system creates and directs a high volume of air through the tank above the water surface to volatize undesirable trihalomethanes in the drawn-up water portion to gaseous state to enter the air flow pattern and exit the tank into ambient air.

摘要:
A portable unit for treating potable water in municipal and similar water lines to reduce and remove undesirable disinfectant byproducts such as trihalomethanes. The unit has a housing with water and air inlet and outlet arrangements. The water inlet arraignment is connectable to the municipal water line to deliver water into the housing where it is sprayed substantially horizontally into the housing along a duct through a splash screen and up against a splash plate. The splash plate redirects the water spray laterally outwardly, rearwardly, and downwardly onto an inclined ramp that guides the water downwardly into the lower part of the housing where it is collected or held until it is pumped back into the municipal water line. In operation, the THM treatment unit is self regulating based on fluctuating downstream water demand and beneficially operates in at least two modes automatically to meet the demand and safety considerations.
