Re: Hole size and bubble size.

Hi, I would advise to use 1mm holes. Usually it's recommended to clean the holes once a year to prevent blockage. Your issue may also be caused by the fact that the airlift does not run constantly. Causing the holes to gather particles, algae, insect eggs and so on during the downtime. I would sugge...

Re: Airlift straight from BIO CHAMBER

50cm sounds very reasonable. I can't say for sure as this is a very specific application. But I believe I have seen similar setups work with a smaller screens just fine. I would expect this to be more than enough.

Re: airlifting model for wastewater sludge

Hi Rita, Apologies for missing this thread. I understand what you are trying to do. However 50cm is still a massive discharge head. A 25W air pump will never be able to provide enough lift to get there. A 110mm rising tube will also be much too large. To give you a rough estimate (I have not done te...

Re: Airlift pump calculation

Hi Vanvu, Sadly I cannot run tests yet. I can't make promises at this point, but am hopeful this will be possible later this year. I can tell you that lifting one meter is going to be highly inefficient. Your required flow rate of 60m3/h is really high as well. I do not think this is a realistic goa...

Re: Airlift straight from BIO CHAMBER

Hi slk, I think both options will work fine. I would pick depending on how you could fit the Airlift the easiest. Make sure you don't lose too much height by fitting that screen under the Airlift. It should still ideally be around 170cm long. It depends on how deep your bio chamber is so you can sti...

Re: The pressure chamber, cheap and good

Hey SLK, Sorry, I missed your earlier post. Thank you for sharing the link. I see you are in Poland, are these parts unavailable there? The link you shared is a company based in the UK. Those reducers should be available in Belgium and the Netherlands for sure. I just had a look and I can find them ...

Re: Airlifts to pull water around a donut pond

Hey Pssymon. Thanks for getting back to me. Sorry to hear work is so busy. Nice to have a hobby! I attached some pictures below. Basically I am thinking a roughly 2 acre pond. The average depth will be around 11 feet, for roughly 7.5 million gallons of water. My thinking is that 100,000 gph gets me...

Hey Manu, Thanks for sharing that file. I've seen it (or a similar one before). It's interesting, but I can't vouch for it completely. I agree that it would be a good idea to share it on the site, you just did, but I understand what you mean, I could make a 'sticky' topic for it in the future. As lo...

Re: EPDM tube diffusers

I know it’s not efficient , noisy and more expensive but other options are not available in India. Also diaphragm pumps like secoh may not survive the hot humid weather of tropics as well as they do in Europe. Now if I try to explain with what I learned from this forum. From here https://www.airlif...

Hi Ted, Good to see you back! I can try to find the images. I may have some saved here. Sadly a lot of older images have stopped working due to the big forum update. I'm currently swamped with work but I will take a look as soon as possible. I have some ideas already. But I will get back to you with...
