Low cost turbidimeter
Make several complete with calibrated scale and fully characterize their accuracy.
Fabrication
develop method to attach drop tubes to sedimentation tank inlet manifold
Demonstration Plant
Evaluate and sketch designs for a mini AguaClara plant that illustrates as many of the AguaClara technologies as possible.
Stacked Rapid Sand Filtration
Design a table top transparent hydraulic model of a SRSF. The model would have shallower and perhaps fewer layers and would include the siphon control system. The purpose of the hydraulic model would be to demonstrate how the filter switches between filtration and backwash. Everything should be made for optimal visibility including the entrance and exit tanks and all of the plumbing.
Take a video of the model filter and link to the wiki.
