Big PictureProblem: Every year there are millions of deaths resulting from contaminated drinking water
Our goal: Is to make a simple cost effective water purification device that can be operated by a common
person in Morocco

Project GoalsResearch and understand project background
(solar, chorine generation, filtration)Understand previous design failures and
successesDesign a prototype for SUNUBuild first round prototypeTest and modify prototypeWrite instruction sheet/video to be sent over
with prototype◦ include safety information
Include a detailed final report with what we found and why we chose design◦ all research included

Last Semester’s Project
What was
accomplished
• Prototype built
• Sealed the
container
• Researched
Scrubber systems

How it worksBrine Water Used
Electrolysis
Chlorine generated
reacts with harmful
bacteria
![Page 6: Solar Chlorine Generator](https://reader035.vdocuments.net/reader035/viewer/2022081507/568163c7550346895dd4fc9f/html5/thumbnails/6.jpg)
Positives of This Model
Cheap Method
All supplies are Accessible
Easy to Use
Generates Chlorine from
Brine water

Problems with Current Design
The current model is not solarRelease of very harmful chlorine gas Purified water is not accessible Installing Scrubber System is complicated

What needs to be addressedThe release of harmful chlorine
gasAccessing the purified water Making the system solar powered

Our WaterThree basic categories
1. Protozoa2. Bacteria3. Viruses

BleachAdd specified amount of bleachWait 30-60 minutes until water is
clearCan purify 5,460 gallons for $4Only kills bacteriaMay also need to be filtered

Carbon FiltrationActivated carbonWhat it’s best at removingWhat it’s not good at removingSilver or KDF-55 used to prevent
bacteria growth

Carbon Filtration Use1. Water passes
through mesh/screen filter
2. Passes through activated carbon filter
3. De-ionizing filter used

Storage Tank/Filtration
Storage tank◦ Stores purified water waiting to be filtered◦ Size◦ Underground to maximize space
Carbon Filtration◦ Pumped up from underground storage tank◦ Removes contaminants and dirt just before use or consumption
