Revision history [back]
Toby,
There are very many methods of reducing fluoride levels, but it would be best to stick with a proven method that is already in use in Kenya, is simple and doesn’t require chemical dosing. Searching the IRC WASH library (https://www.washdoc.info/) I found that the Catholic Diocese of Nakuru produce and re-activate bone char for fluoride removal, so that would seem to me to be the most appropriate line of enquiry (https://www.cathdnkenya.org/water.html). There is a paper on the viability of the bone char operation here:

I hope this helps.
