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 adjust the physical system to use a floc blanket to remove fluoride, find the new optimal PACl dosages, and prepare for the EPA P3 competition,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.
The Spring 2016 subteam will be preparing for the EPA P3 competition in April. The primary goals of the semester are to test out the optimal levels of PACl needed to remove fluoride at different in flow concentrations. Additionally, the maximum time that system can be run will be obtained by analyzing data from the pressure sensors.
