I am working on an educational project that teaches about the process of water treatment using an arduino to automate the process.
I need an aerator that makes bubbles and mixes the water at the same time.
I've seen something similar done a long time ago. If I remember correctly, it was more or less a submersible hobby motor with a 'fan' soldered to the shaft and a tube running down to the 'fan' where the air was sucked in.
Does anyone know of a product that will do this? If not, can anyone explain how I could make one? I can't think of how to put together what I saw.
Here' s video of the aerator I am trying to emulate: Novair 200 YouTube video
Here is a photo:
Thanks!
