UASB - Summer 2018

Ian Cullings, Isa Kaminsky, Ananya Gangadhar

ABSTRACT:

Since Spring 2017, the AguaClara Upflow Anaerobic Sludge Blanket (UASB) Team has been working on a detailed design of modified, pilot-scale UASB reactor originally proposed in an EPA P3 proposal. A UASB reactor treats wastewater anaerobically and produces biogas as a by-product. Working towards that goal, the team has created Python code to record the design process and calculations for this AguaClara UASB.

Over the summer of 2018, the UASB team's main goal has been to finish a complete design of a UASB wastewater treatment system, and fabricate an influent system. Future teams will work on fabrication of the entire system and testing at the Ithaca Area Wastewater Plant before implementation in Honduras.

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.
