Fluoride
Introduction
Fluoride contamination of groundwater is a major, well-known health concern, that still does not have any highly effective or sustainable technologies to remedy it. The World Health Organization suggest the Nalgonda method, but this techniques has several major flaws including a treatment efficiency that is limited to only 70 percent, and a large dose of aluminum sulfate, which causes sludge disposal problems. Instead, we intend on using Polyaluminum Chloride (PACl) as a coagulant to which the fluoride can both adsorb to and coprecipitate with. Our objective for this semester is to build the physical system with a sand filter to trap the coagulant and being the adsorption and coprecipitation.

The goals of the Fluoride Team is to design and create the optimal system for adsorbing and coprecipitating out fluoride from groundwater. |
Goals
The Fall 2015 subteam hopes to find the dosage of PACl required to optimally remove fluoride from groundwater. By quickly redeveloping our physical filtration system and setting up Process Controller, we hope to spend the bulk of our semester experimenting with varying levels of Fluoride and PACl, analyzing our work, and trouble-shooting our system.
