This is circulating water with no lift or resistance. There is no filter medium. One is just spinning water in a circle. Our Olomana Garden air lifts show 300 to 600 gallons per minute being lifted 48 inches above the airlift, where it can be distributed or dropped thru a filter. We installed a Pipe-in-a-pipe air lift on a 24 inch deep fish tank and pumped water at 540 gallons per hour with a 48 inch lift (above the fish tank), or 6 foot off the ground were we drop it into a 3 inch pipe and send the water to two 100 gallon bio-filter (flood and drain), we use only a 60 watt Hakko (Matala) 60 lpm diaphragm. With 48 inches of head, we have 2 psi of water pressure to push thru a filter or bottom flood a false bottom. We do do 1200 gallons per hour if only a one foot lift, dropping the water over a bio-filter. We gave away the patent rights to our inventions so others could learn how air lifts can really produce results. We do a similar system to you, but for the purpose of converting the vertical airlift to a circular horizontal spin of the fish tank. I have built and installed over 450 airlifts (in six years) in aquaponic and commercial shrimp systems. Yours is beautiful constructed and a great display at a trade show....but no work is being demonstrated, as far as I can understand.
Wow.. This is the best demonstration I have seen by far. cheers! What is creating the bubbles please? I have just bought a 60 litre per minute air pump, do you think this will be strong enough? I want to use it for making compost tea. I need to creat 110 litres every 48 hours. This looks like it could move it, help aerate it on the surface and mix it. Cool
In the close up off the pressure chamber it looks like bubbles are only penetrating through one of the 3 rows of 1mm holes. Is there something I'm not seeing? I have drawn up my grid papper to drill the holes and have staggered them so each of the 3 rows is spaced by 1cm and each column does not have a hole above it . . . . . .
This looks like how a toilet works. You have the uplift of the water and then the circling pool of water which the waste is carried away but it wouldn't work well you would find your supper coming back for a visit but nice job showing air can move water.
@Jeroenz0r Veel verschil maakt dit niet naar waterverplaatsing toe, echter voor het afscheiden van eiwitten op dit systeem is hoe kleiner hoe beter ;-) Mvg, Koivrienden
om het overtollige zuurstof te lozen,maar is niet echt nodig als je het uiteinde de buis zeg maar 1/4 boven water laat,staat leuk en kan schuim op komen wat dan weg kan lopen,zeg maar het overtollige zetmeel in water,ps je kunt er ook een 20-30+tal cm mee omhoog brengen,hier word alleen maar veel gebruik gemaakt van rond pompen,
Yes, because there are no live parts in the water The only "disadvantage" is that air lifters are only suitable for gravity filters - they can hardly lift water at all
Good, system been done before, thinking of doing a new aquarium that way, incorporating waterfall return, of a natural filtered sand garden swimming pool water part from koi pond. Don't want to swim with koi & shock'em etc.,chuckless.. Good Luck Lex
I guess because your demonstration recycled the water instead of having it go to waste, no one can understand it. Maybe you should write, "imagine filter here" lol
This is an energy efficient way to move water, 10watt ---> 10m ³ water With this setup we can see how big the openings for the air required, 0.5mm or 1mm ..... Best regards
