Airlift above water level

Post by FerTiliza »

Hi, friends!
Watching the videos and reading Marc´s posts I was wondering if with this airlift method it´s possible to raise the water above the pond level?
For example, to place the pressure chamber water exit above pond level (?)...
Has anyone tried that?

Thanks for your thoughts on this!

Hello Fernanda and welcome.

I'm busy studying at the moment so I can only leave a quick reply for now.
You seem to want to use an Airlift system to water your plants. The main focus of the system we use here is a massive yield at low cost. Discharge head has to be really low. In this video you can see some examples:



Feel free to look at the rest of the videos on our channel to get a better idea of what we do.

I think a different system would probably suit you better.
I will get back to you at a later date.

Good luck!

Hello Fernanda,

With airlift it is possible to raise above waterlevel, but this will be only a few cm's or inches.
when you decrease the size of the riser pipe, then you are able to lift water above the waterlevel, but this is still a low amount.

what amount of water you're thinking about?

Thank you, guys :D

Pssymon, yes, I´ll apply airlift pumping to an aquaponic system.
It consists of a 5000 l pond and a discharge head 2 m high!

So, Bjornd, it will be great to recirculate this amount - 5000 l - every hour.
I´ve seen others airlift methods with aquaponics and yes they use smaller pipes as in the Olomana Gardens videos (olomanagardensaquaponics.com/?cat=35)

Anyway, I´ll probably use your design in a natural pool and it gave me a great insight on somehow apply trompe technology to trap some of the air.

Let´s see!

when you want a flow of 5000 L/hour with a discharge head of 2 metres, then another design of the pressure lift is needed.

we normally use 110mm or 4 inch pipes and when we need more overhead we decrease this size towards 3 or even 2 inch.

It isn't a exact science, mostly DIY.
