Abstract:
The goals of this summer’s Turbidity team were to:
Finish the testing that the previous team had been working on in order to design a cheap (under $20) Turbidimeter that can easily be transported to potential AguaClara facility locations.
Find a relationship between depth and Turbidity that is within 50% accuracy for a specific disk design based on line thickness and spacing.
Fabricate and calibrate 10 turbidimeters that will be ready for shipment by July 28, 2011.
Thus far, the team has managed to improve the design of the original Turbidimeter while lowering cost and increasing portability. All ten prototypes were built, calibrated, and sent to Honduras by the specified date. The only shortcoming was that due to size limitations the Turbidimeter could not measure below 15 NTU, however, this does allow for greater ease of use. The final Turbidimeter design is just over 60 cm in height and costs $4.02 to make.
