Embodiment Construction

[0017] The following detailed description should be read with reference to the drawings, in which like elements in different drawings are designated by like numerals. The drawings, which are not necessarily to scale, show illustrative embodiments and are not intended to limit the scope of the invention.

[0018] Karliner's Patent No. 5,744,072, entitled "Method of Treating Wastewater," is hereby incorporated by reference.

[0019] figure 1 is a top schematic view of a ventilation system 100 including a ventilation device 108 coupled to a forced air source 110 . It should be understood that the designation 108 "ventilation device" is not intended to limit it to ventilation applications. For example, aeration device 108 may also be used in mixing, nitrification, or denitrification applications. A ventilation device 108 and a forced air source 110 are connected to a buoyant support structure 112 .

[0020] In one embodiment, buoy support structure 112 includes frame 102 and b...

Abstract

A device for use in fluid agitation, the device comprising: a hollow drive shaft having a first end and a second end, wherein the first end is connected to a selectively rotatable power source; a first propeller ; a second propeller; and an atomizer, which is connected to the drive shaft; and a vortex shield capable of being immersed in the fluid, which is disposed on the first propeller; in fluid communication; and methods of using such devices.

Description

technical field [0001] The invention relates to a ventilation device for handling fluids. More particularly, the present invention relates to an optional air assisted propeller ventilation device for fluid mixing and oxygen control. Background technique [0002] When handling fluids, an aeration process is used for the purpose of mixing and increasing the dissolved oxygen (DO) level of the fluid. When used in the wastewater treatment process, bacteria and other microorganisms are supplied with oxygen to destroy the organic matter in the wastewater during the purification process. In other applications, the aeration process is used to meet dissolved oxygen requirements when treating water, for example to feed fish and other aquatic organisms in aquaculture. [0003] Known ventilation devices have surface ventilation, diffuser / blower and rotor ventilation. Surface vents pump water up and into the air. Surface ventilation systems require more horsepower and consume more ene...
