Abstract
The goal of the milli-sedimentation team was to find and explore the boundaries between sedimentation and filtration which could be used to reduce the size and residence time of AguaClara plants. The technology was designed using coffee straws that are sized between the spacing of plate settlers (10 mm) and the porosity of filter material (0.1 mm). The size of the plant would be on the scale of a small town or village, less than 1000 residents, replacing what the foam filter did in El Carpintero. One of the biggest challenges for the semester after building the sedimentation-filtration system was attempting to clean the apparatus, as this determined the feasibility of the design.
