Kisii waterfilter

This is a very simple waterfilter that can be used to filter practically any type of water (from rivers, lake, ponds, rain, etc..) by putting one (or more) ceramic waterfilter candle in a small bucket or in a large bucket.
The filter has been first demonstrated and used in the Kisii Water Project in Western Kenya, by RWD (Rural Water Development Project of the Diocese of Kisii and Ngong) in 2003. Since that time many thousands of this simple filter system has been made and are in use by people in towns as well as in rural communities.

Each ceramic candle can give about 20 liter of pure and safe drinking water per day. By putting more candles the total yield can be increaed.

Maintenance is simple, after a while (depends on the water quality) on the outside of the candle some dirt may accumulate and the candle needs to be cleaned with a fine brush, NOT with soap! Soap will clogg the filter and stop it from working.

The specific advantage is that the ceramic filter candles are cheap and often available as spare waterfilter candles for the more expensive systems from companies susch as Pozzani, Stefani and Berkely for instance.

Any type of plastic bucket can be used, simply by making a small hole in the lower part of the bucket.

We do not recommend to use the cheaper ceramic filter candles that are manufactured in India because it is our experience that they start to leak at the connection, so they are not safe after a while.

looks like me in the morning, haha j/k.

I know the carbon in these 'candle' type filters can take the filtration down to an impressive 1 micron, but do they filter out the flouride from our tap water as well? anybody know? cheers!

[filoIII]

how many microns does it filter down to?

[keminokana]

how does it work?
