The Fluoride team seeks to develop a sustainable, inexpensive fluoride removal system for treatment of contaminated groundwater. The team is developing a novel reactor system that will be ultra-low energy and low maintenance. The reactor system is based on the Nalgonda method that has been adapted for continuous flow and with a novel fluidized bed that is coupled with lamellar sedimentation. The fluidized bed and lamellar sedimentation process efficiently separates the coagulant nanoparticles that have formed bonds with the fluoride.

The team is testing the feasibility of using a single stage reactor system rather than a 2 stage system for cases where the fluoride contamination levels are not excessive. They are currently designing a gravity powered pilot scale reactor that can be used for testing performance in the field.
