Preliminary Assessment of Low Cost Local Sorbent Materials for Water Defluoridation in Keren, Eritrea
Keywords:
batchdefluoridation, Eritrea, fluoride, fluorosis, Keren, local sorbentAbstract
Water in some parts of Eritrea has fluoride level above WHO guideline of 1.5 mg/L. One of the communities in Eritrea exposed to high fluoride in water is Keren community and as a result, they suffer dental and skeletal fluorosis. Fluoride sorbent local materials named crushed burnt clay pot, household ash, Keren and Adigerghish soil were studied in a batch defluoridation. The effect of amount of adsorbent, pH, contact time, particle size and fluoride concentration were examined.
