Introduction to the Crielsieve, a revolutionary pre-filter!

While we focus on the development of Airlift technology, we are looking to improve every aspect of running a pond succesfully, with as little maintenance as possible. The filter is a very important aspect of any stocked pond. Keeping it clean can be quite a challenge. Most of us are familiar with th...

All current test results! Chamber + Membrane Airlifts!

Good day, Here you will find all relevant test results as measured by Marc, Gino and Guyke. All tests were done with Marc's quarantine pond test setup using an ultrasonic flow meter. The flow was measured at the inlet to the collector (not in the Airlift) to prevent inconsistencies due to air bubble...

What is an Airlift and how does it work?

Good day, In this topic I will explain the basics of Airlift, in particular I will discuss the types we like to use. What is an Airlift? An Airlift pump, in essence, is just a pipe placed vertically in a body of water. At the bottom the pipe has an air supply connected, powered by a compressor or an...

Kicking things off

Good day! I'm done studying for now, which means I have time to work on the forum again. Things are looking a bit empty and we have a lot of valuable information which still has to be added to the different sections. I will create the necessary topics the coming days, and make some small changes to ...

Re: Airlift above water level

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 s...

Re: The pressure chamber, cheap and good

Interesting, I'm not really sure how to imagine your outlets. It is indeed important to look at anything in your filter area that is causing drag, and try to optimise it without risking a big loss in bio filtering capacity. You seem to be quite serious with your project! If you want you can start a ...

Re: The pressure chamber, cheap and good

Hi Frank, Thanks for sharing these results with us! So you are running one Airlift, which gives 24.000 litres per hour, at an energy consumption of 22,45 Watt? Are you using four outlets? Since you specify 4 x 6000 litres per hour. This is a good result, considering the filter is also causing drag. ...

Re: The airlift pond of Marc and Caroline (built in 1997)

We should test this in your test setup Marc, so we have some figures to go with it. I'm quite curious how much it will affect the results.
Maybe it will work in certain setups, but I would be surprised.

Re: The pressure chamber, cheap and good

Hi Frank, I believe the JDK-20 is less powerful than it's predecessor, the SLL-20. I've seen people suggest the JDK-30 as the better alternative, as this will surely achieve the results of the older SLL-20 and more. Ofcourse it will use a bit more power, I am not sure if the energy consumption to ou...

Re: The airlift pond of Marc and Caroline (built in 1997)

Hey lars, In the video Marc refers to this part as an adapter from 125mm to 110mm. When we built a small Airlift here we did not use the exact same part, we found something else that worked. This was at a local hardware store with limited PVC pieces (in the Netherlands), we had to use a 100mm rising...

Re: The airlift pond of Marc and Caroline (built in 1997)

Good day, I just added the second part to Marc's pond development in the first post of this topic. Since Marc's English is not perfect, I edited the opening post and translated the second part for him. I am also running the Youtube channel, and the video 'Airlift: How to build, part two' should be u...
