Bio Sand Filter

[Pesadelo80]

The deal is gather water from the rain, and spark the chain reaction.

You can lvl up your filter system by separating the layers by using ''moskitos nets''(there are many types of them), adding proper layers of rocks,charcoal,and gravel.

And to up grade that, you double it !! By using more filtering barrels :D

Thats it !!

clear water is not good water! it s lesson i ve teatched in haiti when i got there

sand filter does not remove the air pollution fro the rain water.

neither SO2 nore heavy metals (lead) nore the organic chemicals ( insecticide, light petroil maiden chemicals)

[samljer]

whats wrong with you, too proud to use normal stuff, like carbon

[WilsonStanley]

very informative. what is the solar panel on top of the barrel for?

Kool

[smartbetta]

Did u when and see ur doctor the next day? Lol

[maidmercy]

lol yeah don't try it at home until after you boil that filtered water. Might want to add that in there somewhere.

[Zatataw]

After a certain period of usage, many dirt and particles will be stuck inside the sand, right? How to clean them?

[fireseed23]

Now we just need to know if this can remove chlorine and fluoride, a main cause for concern in city water supplies...

I use Borax to fight fluoride, but this would be more self-sufficient yet. Please reply if you know.

[gavinwph]

Have you ever been ill from drinking the filtered water?

[Raykenn1]

Excellent! Thanks for the video. I have watched dozens trying to find the info you presented here.

[KeyCarist]

@Raykenn1 I agree completely- much more informative about the specifics of how the biofilter works than other videos I have seen.

DEZEVNICA JE NAJBOLSA KER NIMA NOBENE KEMIKALIJE,,,CE VODA IMA KEMIKALIJE JE POTREBNO SE POSEBNO KEMICNO OCISTITI....

[lslavychecker]

Odlicno za dezevnice in vode ki nimajo kemikalije-drugace je potrebno se dodatno ciscenje....

[doodadica]

Nice work! Something you might want to look at is an article you can find if you paste the following into google: "sea shells used to clean up heavy metals"

I don't know whether adding a layer of crushed sea shells would be effective in improving biosand filters to remove heavy metals, but it's something to investigate.

I'm going to post this comment in a few places to help seed this idea, because I haven't seen anything being done with this.

[ArashiNage]

Thanks for the info about the sea shells, I'll check it out. Keep posting the idea!

[MrB0TT]

Would it be benificial to add a layer of charcoal?

[MrElektrolyt]

lol schmutz decke

[HideousMonsterHank]

Why can't I try it at home?

[ArashiNage]

...because if the filter is not built properly, the bacteria in the water could give you some explosive shits! :D

[wonderboy9083]

@HideousMonsterHank

the system needs to have dirty water run through it for 2-3 weeks to build up the layer of shmutzdecke, it must be kept moist at all times. Then the water can be used. I think. Correct me if im wrong.

[StrictlyJmD]

where can I buy this type of sand? you can send info to..shootitto@aol.com

[daviddpb75]

What is your active carbon reservoir? Charcoal??

[theafrodude22]

would be cooler if you did number 1 in the bucket then filter it then fill a cup up etc jk.

cool video, wonder how well that filters the water and how long the filter lasts.

[cdltpx]

After running it through that massive filter you might want to run it through one of those ceremic silver filters and a activated charcoal filter. Great work you have a little water for life we need to return to building cisterns to store water we are counting too much on ground water supply in some areas. Eventually cities will have to shed population due to lack of water.

[gilberto2012]

great video, What's the name of the beneficial bacteria and how much does cost?

[ArashiNage]

Im not sure of the actual name of the bacteria. It costs nothing! It forms naturally on the top inch of the sand. This bio layer forms after a few weeks and is called Schmutzdecke. This biological layer traps and feeds on microorganisms and contaminants in the water.

[405george]

@ArashiNage anybody done any testing with urine, will it clean it enough to drink? thanks

[gfpfan]

Great video; thanks for the detailed instructions - every community shelter should maintain one of these - the convenience of bottled water and commercial carbon filters can disappear in a hurry,

[ArashiNage]

Hello, Thank you for commenting. When the top bio layer was complete, it's flow rate was approximately 15 liters / hour. The flow rate increases and decreases according to the bio layer (the more gunk you have at the top, the slower the water passes through).

[ArashiNage]

You are correct about how sand filters a water spring... HOWEVER, with a spring, the water passes through ALOT of sand, much more than what could be put into a barrel. (like 10 feet of it).

In order to filter correctly using the depth of barrel, you must use very fine sand, not the type you could dig up. I use super fine sand purchased from a sand gravel supply company. It's the fine sand used in swimming pool filters. Please note, the BIO LAYER is what does most of the filtering.

[fireseed23]

This is really, REALLY cool man.

But I think the world could really benefit from this a whole lot more if you did give us a few more simple figures. How long does it take to filter one liter? Can you use a type of sand that can be dug for self-sufficiencies sake? I assume that is how water springs work. Cheers!

[ArashiNage]

see above reply, thanks!

[bassamry]

how many liters does it make in an hour?

please reply

[razormanxx]

you didn't swallow that water did you? looks like you spit it out off camera. this is go green trickery.

[ArashiNage]

It should last for a long time, not sure how long though. It depends on how dirty the water is you are filtering. The more it filters, the more stuff gets trapped at the top layer. As this happens, the flow rate will decrease. You will have to remove some of the top layer of slime, and then let it regrow.

[razormanxx]

you're a fricken hippie. how long can it keep filtering, and does that slim form naturally or did you add something
