Fluoride - Summer 2018

Ching Pang, Kevin Sarmiento, Cheer Tsang

Abstract:

Fluoride is a major contaminant in drinking water in many parts of India. The fluoride team's overarching goal is to create low cost, compact, and sustainable solutions to fluoride contamination in drinking water. The Summer 2018 team aims to continue and expand upon the work of previous teams by running experiments with both the pump-controlled system and the gravity powered system. The goal for the summer is to optimize the amount of coagulant needed to reduce the effluent fluoride concentration to 1 mg/L, as per the fluoride standard in India and design an easily adjustable gravity powered system. In addition, the team aims to develop a simple user guide for the fluoride probe in order to maximize future teams' efficiency.

Fluoride Auto - Fall 2018

Fluoride Automated System

Abstract:

The Fluoride Auto subteam seeks to develop a sustainable, inexpensive fluoride removal system for implementation in upcoming AguaClara plants in India. Using the apparatus developed in previous semesters, the team continued running experiments testing how various concentrations of PACl affect fluoride removal. The team then analyzed the variability of the Langmuir isotherm generated by the summer 2018 Fluoride team. This analysis factored into the overarching goal of developing a model to predict an optimal coagulant dosage given both influent and target effluent fluoride concentrations.
