2016 R&D 100 Award: Sustainable and Affordable Fluoride Removal (SAFR)

2016 R&D 100 Award: Sustainable and Affordable Fluoride Removal (SAFR)

November 09, 2016

Award Recipient(s) 

Ashok Gadgil, Katya Cherukumilli, Yash Mehta and Subiksh Chandrashekar

Accomplishment 

A team led by Ashok Gadgil developed Sustainable and Affordable Fluoride Removal (SAFR), which uses mildly processed bauxite, an aluminum-rich ore available ubiquitously worldwide, as an adsorbent for remediating field-relevant fluoride concentrations in groundwater to reach the 1.5 milligrams-per-liter limit established by the World Health Organization as safe for drinking.
Because SAFR eliminates the costly and wasteful processing involved in refining bauxite into higher-end products for fluoride removal, it is a more sustainable method that also has lower energy costs and lower carbon emissions.
