This project was chosen because Dr. Gary Eden and Dr. Sung-Jin Park brought us their desire to develop a humanitarian application for their new technology, a simplified ozone reactor. The motivation to develop a new application arose from the technology’s ability to produce clean water at low cost and high efficiency.

Currently water purification systems use expensive, environmentally harmful chemicals to purify water. In contrast, our system will utilize low cost, treated foil, and sustainable energy to produce clean water. The simple aspects of our design will help it resist breakdown and limit maintenance costs. These are important aspects because we hope the system will be utilized in third world countries, where the lack of clean water is a growing issue.

Power Regulator Block Diagram in Detail.

When the reactor is turned on a signal will be sent to the regulator to check the battery. If the battery is within the appropriate range to run the system then it will turn on the switch from the battery to the system and will turn off the switch connecting the battery to the solar panel. From there the regulator will continue to watch the battery and monitor the levels making sure that it has enough power to supply the rest of the system.


This is the main component that is driving the reactor. Because the reactor requires AC and the solar panel and battery outputs in DC, that means that the converter is essential to the overall functionality of the design. If the DC-to-AC inverter is not functioning correctly that would mean that the reactor will not produce ozone, defeating the purpose of the device. So by running the solar panel through the DC-to-AC inverter, we will monitor the output. If it is to what we desire than it is functioning the way it should be.


Issues and Risks

We agree to uphold the IEEE Code of Ethics and will address any issues and concerns that may occur in our project.

In doing this project, our goal was to create a system purely for humanitarian purposes. When this project is finished, in no way will we try to exploit the abilities of this project. It will be used for only one purpose, to give the people in third world countries access to clean, affordable water. We will not take this chance to make profit off of this project since most of the main components were designed by other people.

We were the ones that brought it all together. On that note, throughout the entirety of this project there have been many circuits and components that were not designed by us. The circuit design for the pulse generator as well as the reactor were designed and built by Professor Gary Eden, Professor Sung-Jin Park, and the graduate students at the optical lab. In no way will we take credit for coming up with the design for any of these components and they will be properly credited for their design.
