This fall, I and my teammate Jenny Guan are continuing continued work on foam filter for deployment in Spring 2013. This device is intended for small communities such as a school.
Our tasks for this semester include This semester we attempted to complete the following :tasks.
1. Add a chemical dose controller for coagulant and chlorine to the filtration system.
2. Communicate with Agua Para el Pueblo about the best method to deploy the technology.
3. Find a correlation between NTUs and time to breakthrough/overflow. an operator friendly way of determining breakthrough
4. Find a way to run the filter without electricity.
5. Create a user manual in Spanish
The tasks in bold are ones that are still in progress.
