Welcome to AguaClara! AguaClara is a research organization at Cornell University that designs sustainable, electricity-free water treatment. This technology is then implemented in Honduras and India in a partnership with Agua Para el Pueblo and AguaClara LLC. All of AguaClara's research is open-source so please look through this wiki page or visit our website aguaclara.cornell.edu to learn more!
This semester, I am on the Linear Chemical Dose Controller Team. The main idea of the Linear Chemical Dose Controller(LCDC) is to have one device, the LCDC, to dose three chemicals at different locations in the plant. Two of the coagulant doses wil be applied in the in entrance tank. The third dose, chlorine, will be applied after filtration.
After creating a working LCDC, we wanted to test it to maximum flow and minimize percent error to no more than ten percent. In order to achieve these standards calibration must occur. We tried different methods to effectively calibrate the system such as changing the height of the constant head tank (CHT), cutting the dosing tube, and sometimes even changing the location (distance away from the LCDC) of the CHT. These different techniques lead to smaller total percent errors in expected flow vs actual flow which is detailed in our report. This was our major concern for this semester; calibration and reducing error.
