This semester the goal of our subteam was to determine a mathematical model stack rapid sand filters. By monitoring the effluent turbidity and head loss of the filter at a variety of PACl dosages, we looked for trends and disproved theories. The goals for future semesters will be to test new theories we determined from our experimental observations.
Summer 2014
This summer I will be working on the laminar and turbulent tube flocculators. The first tasks will include updating the water supply tank and clay dosing systems of both the systems. After the laminar tube flocculator is updated we will test the newly added SWaT system and compare its results to those observed in past semesters using the FReTA system. The majority focus for the turbulent tube flocculator will be adjusting issues with the apparatus and process controller file. Once these changes have been addressed, the goal will be to analyze how flocculation differs in turbulent conditions as most AguaClara plants have turbulent flow conditions.
