Buoyancy Hydro - Amazing Airlift pump tests.mov

Deep water Airlift pump tests, in lessines Belgium. Small volumes of air are released into submerged pipes (5-45m deep) creating a buoyancy induced water flow up to 30 times the volume of the air that is introduced.

Our turbine design places the turbine under the pipe and captures the water entering the system. This is far more efficient then a conventual method you have described. Approx 70% of the energy of the compressed air can be recaptured and returned into electricity, therefore a loss. The idea is an efficient conversion system.

Thats HUGE, I thought bubble lift was restricted to about 2" line. this reshapes my thinking completely. is there any special way in which the air is introduced into the pipes (some form of distributor fitting ) or does it just get injected at depth and find it's own balance of mix on the way up?

[BuoyancyHydroEnergy]

@AircondGypsy - the air isn't injected via a distributor, the air water mix is controlled by the volume of air and the diameter of the tube, a change in either of these parameters will naturally create a different flow mix. To a lesser extend depth has also an effect. Even without a pipe or line, air rising in water creates a flow of water towards the surface. You can see this by observing a diver from the water surface.

The largest flow on the video - Air pressure 64 psig @ 9.9lt/s / Water flow 350lt/s / pipe diameter 490mm (internal) / Pipe Length 35m, 34m submerged.

you keep adding pipe - but you're only pumping it a couple of feet above the water level.

oh my fucking god howmuch water comes up there from a bit air letz say u pump it 3 meter higher and let it run to a warer turbine and power the little compressor whit it how much energy is left ???????

[romandybala]

The lift of this setup is only the height of the lip of the pipe above the level of the water. About 18 inches or so. Whats the big deal? Get it to fill one of those large section pipes at full height above water. Am I missing something here?

What air pressure and volume delivered what volume of water through what diameter pipe over what period of time at what depth? Please :)

Hi,

I would like more information about you product. I want to pump 10 cubic meters per second.

Please contact me: joseroman@albercas.com.mx

Nice. I guess its one way to also airate and mix large bodies of water.
