Efficiency of Portland Pozzolana Cement as an adsorbent in removing excess fluoride from groundwater
Highlights Drinking of fluoride contaminated groundwater causes dental and skeletal fluorosis. High concentration of fluoride (>1.5?mg/L) has been reported by Central Groundwater Board of India in Mathura District of Uttar Pradesh. Portland Pozzolana Cement used as an adsorbent, reduces fluoride up to 86% and 54.15% from synthetic water and groundwater respectively. PPC as an adsorbent […]

Cubical-Shaped Rods of Pectin-Hydroxyapatite Composite for Adsorption Studies of Fluoride by Statistical Method and Adsorption Experiments.
Note from Fluoride Action Network: “Since all methods [to remove fluoride] produce a sludge with very high concentration of fluoride that has to be disposed of, only water for drinking and cooking purposes should be treated, particularly in the developing countries.” Reference: Fluorosis (see Interventions), World Health Organization Abstract This research details the synthesis and […]

Defluoridation of water through the transformation of octacalcium phosphate into fluorapatite.
Abstract The consumption of water with fluoride concentration higher than 1.5 mg/L (WHO recommended limit) is recognized to cause serious diseases, and fluoride removal from natural contaminated waters is a health priority for more than 260 million people worldwide. The octacalcium phosphate (OCP), a mineralogical precursor of bio-apatite, is here tested as a fluoride remover. […]

Fluoride removal from water by electrocoagulation: Effect of the type of water and the experimental parameters
Highlights Fluoride ions can be removed efficiently from water by electrocoagulation. Lower aluminium amounts are required with hydrogencarbonate anions. Temperature, concentration and conductivity impact on the treatment performance. In any condition, more efficient treatment is obtained with pH lower than 7.5. Abstract Contamination of the ground water with fluoride is a great problem worldwide. Removal […]

Simultaneous removal of fluoride and arsenic from well water by electrocoagulation
Highlights Electrocoagulation is a process able to treat and remove fluoride and arsenic simultaneously from drinking water. Critical factors in the electrocoagulation process for simultaneous removal are pH, current density and treatment time. Acidic pH is more favorable for fluoride removal Arsenic removal is less complex than fluoride removal, high removal efficiencies were reached without […]

Synthesis of bone char from cattle bones and its application for fluoride removal from the contaminated water
Highlights Bone char is synthesized by thermal treatment of cattle bones at 350°C. The maximum adsorption capacity was found to be 10.56 mg g-1. The specific surface area was determined 79.34 m2 g-1. Abstract This study is focused on the synthesis of bone char (BC) and its application in adsorptive removal of fluoride from the […]

Facile method to synthesize efficient adsorbent from alumina by nitric acid activation: Batch scale defluoridation, kinetics, isotherm studies and implementation on industrial wastewater treatment.
Highlights Efficient fluoride removal potential from industrial wastewater. The fluoride removal efficiency was increased from 74.18% to 97.43%. The maximum adsorption capacity of novel adsorbent was 45.75 mg/g at 45°C. Adsorbent exhibited > 99% regeneration efficiency and four cycles of reusability. Abstract The excess amount of fluoride contamination in the groundwater or industrial effluents fosters […]

Ethiopia’s water problem: Excessive fluoride treated with bones
See fascinating short video at the start of this short article High fluoride levels in water cause teeth discolouration and in extreme cases, bone decay. In many countries, fluoride is added to water and toothpaste to make teeth stronger. But, when there is too much fluoride, it can be toxic. In Ethiopia, at least 16 […]
