Fluoride Contamination in Drinking Water in Sri Lanka and Fluoride Removal by Using Chicken Bone Char

Title Fluoride removal from drinking water by adsorption using bone char as a biosorbent

Optimization of regenerated bone char for fluoride removal in drinking water: a case study in Tanzania.

This paper presents findings of a study on optimization and application of the regenerated bone char media for the defluoridation of drinking water in Tanzania where more than 30% of all water sources have fluoride concentrations above the 1.50 mg/I which is recommended by the World Heath Organization (WHO). In this study, regeneration temperature, regeneration duration, contact time, regenerat...

Review of fluoride removal from drinking water.

Fluoride in drinking water has a profound effect on teeth and bones. Up to a small level (1-1.5mg/L) this strengthens the enamel. Concentrations in the range of 1.5-4 mg/L result in dental fluorosis whereas with prolonged exposure at still higher fluoride concentrations (4-10mg/L) dental fluorosis progresses to skeletal fluorosis. High fluoride concentrations in groundwater, up to more than 30 ...
