Fluoride Removal In Small Water Systems: A Coagulation Approach

This project is developing a treatment system for simultaneous removal of fluoride, natural organic matter (NOM), and particles from natural waters used as drinking water sources. Research is developing a mechanistic understanding of interactions among fluoride, organic ligands, and aluminum during enhanced coagulation processes. The efficacy of the system is being demonstrated through small-scale pilot testing of a continuous flow system using actual source water for drinking water. The treatment system optimizes coagulation process for removal of turbidity, NOM and fluoride. The results will provide a set of validated guidelines for the implementation of the enhanced coagulation process for simultaneous removal of NOM and fluoride.
