摘要:
A diffuser module and system for diffusing gas into liquid such as in aeration/mixing of wastewater. Each module has a header pipe and diffusers which receive gas from the header pipe. Each header pipe is equipped with a truss for enhanced structural strength and resistance to bending. The truss may take the form of a buoyancy/ballast pipe connected with the header pipe by purlins.

A diffuser module and system for diffusing gas into liquid such as in aeration/mixing of wastewater. Each module has a header pipe and diffusers which receive gas from the header pipe. Each pipe is equipped with a smaller internal pipe arranged concentrically to provide an annular space which receives the gas and supplies it to the diffusers. The volume within the internal pipe can serve as a ballast chamber or a buoyancy chamber or both.

A buoyant wastewater aeration apparatus includes a buoyant float pod and at least one air conduit leg removably attached at a leg input end to a respective air supply outlet. The float pod further includes a leg-retainer structure that accommodates efficient engagement/dis-engagement of the air conduit leg at a known region of the leg. The leg-retainer structure may be in the form of a resilient clamp having an open end for removably engaging the known region of the leg. Alternatively, the leg may have attached thereto in the known region thereof a leg retainer-engaging structure that surrounds the leg, wherein the leg-retainer structure is a non-resilient split-ring having a given shape and dimension. The split space has a dimension sufficient for the leg diameter to pass through. The leg-retainer structure and the leg retainer-engaging structure have complimentary shapes and dimensions that provide a removable, engagement of the leg retainer-engaging structure concentrically within the leg-retainer structure. When the leg retainer-engaging structure is concentrically engaged within the leg-retainer structure, the leg's air input end is connectably aligned with the air supply outlet. An associated method for servicing the apparatus without removing the apparatus from the working environment is disclosed.

A solar activated water aeration station for introducing oxygen at a predetermined depth into a body of water is disclosed. The station includes a floatable base having a solar panel capable of being adjusted through a range of inclined positions, an anchor connected to the floatable base for orienting and maintaining the floatable base in a pre-selected position with the solar panel having a southern exposure, control means mounted on the floatable base including a motor and air pump operated by the solar panel so as to provide a continuous stream of oxygen through an aeration tube connected to the motor and air pump, in order to deliver the continuous stream of oxygen to a body of water at the desired predetermined depth.
摘要:
A multistage water purification method in which water purifiers are arranged in stages in water regions of different depths. Air is made to ascend intermittently in each depth region by the water purifier to stir and mix the water with the air to enrich the water in oxygen thereby to purify the water. Disclosed also is a water purification apparatus for carrying out the water purification method. The apparatus includes an upper stage water purifier having a buoyancy chamber, a pumping sleeve and water suction tubes, and at least one lower stage water purifier having an arcuate deflector, a pumping sleeve and an air chamber. The upper stage water purifier and the lower stage water purifier are connected in series in vertical alignment or, alternatively, offset in the horizontal direction from each other.

A diffuser assembly with a buoyancy vessel and a chamber for buoyantly raising the diffuser assembly for maintenance work. The diffuser assembly has a support structure, diffusers connected to the frame, and a buoyancy vessel positioned on the frame, capable of alternating between a state of buoyancy or ballast.
摘要:
The invention relates to a method for stirring and/or aerating fluids, particularly sewage, having the following cyclically repeated steps: aerating the fluid by means of an immersed aerator for a predetermined first period of time (t1) using an aeration device (1) disposed on a carrier (3, 43) designed as a floodable hollow body (2, 42), the hollow body (2, 42) being flooded and air being brought into the fluid by the aeration device, whereby the potential for nitrification is created in the fluid; stirring the fluid by means of the immersed aerator for a predetermined second period of time (t2), the air infeed by the aeration device (1) being throttled or turned off, and previously flooded hollow body being evacuated in order to fill the hollow body (2, 42) with gar or air, the immersed aerator assuming the function of mixing device in which fluid rises upward, thus mixing the fluid, where in the potential for denitrification is created in the fluid; and an immersed aerator.

摘要:
A method and apparatus for aerating a surface layer in a stratified liquid body using a depth-adjustable, fine bubble, surface layer aeration unit comprising: a body comprising at least one hollow internal structure; an air inlet communicating with the at least one hollow internal structure, whereby air from an external air source may be introduced into the at least one hollow internal structure; at least one fine bubble aerator communicating with the at least one hollow internal structure, whereby air from the at least one hollow internal structure may be released through the fine bubble aerator into an adjacent fluid; and at least one weight pod attached to the body, wherein the at least one weight pod comprises structure for adjusting the weight of the at least one weight pod, whereby the buoyancy of the aeration unit may be adjusted so as to permit the at least one fine bubble aerator to be positioned at a desired depth in a fluid body.
