Any interest in …
Any interest in submitting a video that details the construction? Looks like a good concept, perhaps you could elaborate on how the pump functions and what is involved in the filtration system.
Thanks
great job! but …
great job! but could u tell me how to make e pump? i really need to know for my project. Also, how do u clean e filter?
Young lady, I am …
Young lady, I am proud of you. Well done. could I use this in my farm? do you have any alteration, instead of bicycle or elcetric? What is the cost of this machine?
Most of the clips …
Most of the clips dont explain that a correctly built bio-sand filter does far more than filter the dirt. It functions by creating a culture of good bacteria that feeds on the infectious bacteria. It takes two to three weeks for this predatory culture to become effective.
Sediment filters …
Sediment filters don’t remove bacteria. Make it more efficient by adding an electric producing mechanism on the other side to counter balance the work load and that electricity can in turn be used to power a uv stearalizer. Then you’re talking.
Exhilirating!!!!

I wish i could give you more than 5 stars.
I think tat you should have cut your video to many parts so you won’t have to redo it every time you make a mistake.
But overall it was great.
I just subscribed to your videos please subscribe to mine.
Thank you
Your point is well …
Your point is well taken.
I didn’t realize pedal power was a criteria.
P.S. – Really enjoyed your video.
While that might be …
While that might be a simpler solution, the contest for Specialized required the use of pedal power. And, I think it might be easier to come up with a bicycle set up in a third world country than a stair master. I could be wrong though. My purpose for the bike was to use something that could be fairly easy to come by and fix if there were ever any problems. At least with a bike, the owner might have some clue on how to work on the bike without making up a completely new mechanism.
Nicely done there …
Nicely done there Emily.
I like the idea of utilizing a bicycle, but how about using a ‘stairmaster’ mechanism (as simple levers), instead? That might be a simpler mechanical solution, eh?
Keep up the good work!
Great job Emily!
…
Great job Emily!
I’ll bet you could scale that system up quite a bit by taking advantage of the bicycle’s gearing system, and using a higher flow-velocity pump.
I wonder how long you’d need to ride the steed in order to get a day’s or week’s worth of water for a typical household… Probably not more than an hour.
Pretty cool!
I like that …
I like that everything is fully contained. On some other filtration systems I’ve seen, the water is going into a cup.. if you are in a third world country.. who’s to say what can get back in?
very nice video and …
very nice video and a great natural cleaning technique. Thanks
It is a good idea, …
It is a good idea, but I definitely can’t take credit for it. There is lots of information and research out there for the implementation of slow sand filters.
pretty brilliant… …
pretty brilliant…using good bacteria to eat bad bacteria-! Never would’ve thought of that…
On top of the sand, …
On top of the sand, a layer called “schmutzedecke” (German for “dirty skin”) eventually forms. It’s basically the good bacteria eating all the bad bacteria. It has to be skimmed off and started over periodically. As the water travels down, the bacteria is the biological cleaning agent, and the sand is the physical agent that traps particles.
Great idea but does …
Great idea but does it clean out bacteria?
