Fluoride Auto - Cindy Jin, Melissa Louie, Mike Rees
Abstract:
The Summer 2019 Fluoride team investigated issues related to the Automated and Gravity systems, with the goal of determining ideal conditions for removing fluoride. Initial qualitative tests prompted fabrication changes, such as an increase in the plate settler angle in the sedimentation tube. Jar testing was also done to examine if a floc blanket is needed for fluoride removal. Several changes in the sedimentation tube were tested to develop an optimal system for fluoride removal. Fluoride concentrations were measured with an ion electrode to determine removal efficiency and to continue developing the Langmuir Adsorption Isotherm model.
