Household water treatment: defluoridation of drinking water by using bone char technology in Ethiopia
conference contribution
posted on 2018-02-12, 15:08 authored by Samuel Esayas, Michael J. Mattle, Lema FeyisaThe first phase of a collaborative project aims at testing the acceptance and performance of bone charbased
fluoride removal filters in Ethiopia. The filters were produced by the Catholic Diocese of Nakuru
(CDN), Kenya and supplied to 121 households in two project sites in the Great East African Rift Valley.
Each unit was regularly monitored, while providing technical support to all applicants. After a study
period of one year, more than 80% of the filters in Meki (Weyo Gabriel) and 100% of the filters in
Shashemene (Chalalaka) are in use. None of the users expressed any objections concerning the use of
charred animal bones, independent of religious or cultural background. Fluoride removal efficiency of
the filters was satisfactory, although lifespan is limited due to very high fluoride concentrations in some
of the groundwater sources (up to 23 mg/L). Filter design requires modification for improved
performance in Ethiopian communities.
