Fall Semester Contributions

This fall, I and my teammate Jenny Guan continued work on foam filter for deployment in Spring 2013. This device is intended for small communities such as a school.  

This semester we attempted to complete the following tasks.

1. Add a chemical dose controller for coagulant and chlorine to the filtration system. 

We were able to add a CDC for the coagulant and chlorine to the filtration system. We calibrated them with clean water, so a future team will need to re-calibrate with the correct fluids in case there is a difference in the viscosities of coagulant and chlorine.

2. Communicate with Agua Para el Pueblo about the best method to deploy the technology. 

We did not communicate with Agua Para el Pueblo as we struggled to create a completed filter device for deployment within the allotted time span.

3. Find an operator friendly way of determining breakthrough

We were able to develop a Secchi Disk that can be used by an operator at a fairly high turbidity. It should still be calibrated by a future team to establish the best location to place the Secchi Disk and at what turbidity the disk disappears.

4. Find a way to run the filter without electricity. 

We were able elevate the tank to an appropriate level to allow the system to operate without electricity.

5. Create a user manual in Spanish

We created an illustrated user manual in Spanish for operators. 

We recommend that a future team investigate the following:
