A remarkable and inexpensive way to produce clean water

An Action Against Hunger staff member in Kenya, David Githiri, giving a brief presentation on how something as simple as a Bio-Sand filter can transform dirty and unhealthy water into clear and healthy water. A Bio-Sand filter is made with only cement, rocks, and sand. Assembled , this is a very practical way of providing clean water to areas that have limited water access.

it is seramic, built with ground rice and some other natural material.

it is then coater with silver for additional purufication. the best thing id=s there is no plastic residue in seramic filters. so the water is beter than commersial plastic filters. google the how to make it vid.

[dijimeeks]

any explanations on how to build it?

@bill65761 I'm sorry... what are you referencing to? I think you took one of my comments out of context. If this is about Britas being an excellent grem breeding ground; one does not boil water before using said device. If you did... well, good for you, I guess. :/ However, it would be a bit of an overkill process for the developed world, and the Brita/ boiling combo is not very practical for the developing world.

@jtg001 Would you mind explaining how it is that the dead germs are going to breed? NEW germs enter and breed ... but only because someone was sloppy after the boiling.

@B4realalready Just let it sit, uncapped. The chlorine will off-gas.

@28 seconds he pours the glass of dirty water on the ground instead of just pouring it into the filter.

[B4realalready]

@jtg001 Our city water is supposedly clean and safe. It smells and taste really bad. Extremely strong taste of chlorine. I drink a minimum of three qts. of water a day. No soft drinks ever. I just need a filter to get the chlorine taste out. (not at the exspense of breeding harmful bacteria in filter)

[jtg001]

@B4realalready: I haven't heard anything bad about the Brita, but I think it's kinda silly if your concern is health related. Yes, it'll taste different, maybe even better, but the water we get is very clean. AND unless you are willing to invest a few hundred dollars on a personal reverse osmosis unit, you really aren't "cleaning" it anymore, so if you're source is bad, you = S.O.L. Also note, if you don't keep up with the filters on these, they make excellent breeding grounds for Germs

@jtg001 I've been drinking distilled water for a long time. Thanks for the info. Guess it's time I invested in a filtration system. Any recommendations? Thanks.

It's a great start. Too bad a similar device isn't commercially available for solar power. I dream of a day when a device can be made that will suck enough moisture out of the air to meet a household's needs so we can tell the water barons to piss off for good. Nice to think about, but that would no sooner happen than they would start claiming rights to air moisture. For those of you complaining about the effectiveness of this thing, it's still better than NO filtration for these people.
