Enclosed Stacked Rapid Sand Filters are an adaptation of rapid sand filters optimized for flows less than 3 L/s. SRSF is a game changing technology invented by the AguaClara team that is significantly simpler to operate than conventional rapid sand filters. LFSRSF are currently being built in AquaClara plants in India to treat flow rates of around 0.8 L/s. |
Fall 2016
The overall team goal for this semester is to design and fabricate a new EStaRS for use in the 1 L/s plant. The team aims to reduce the filter height and make improvements based on problems reported by previous teams. After researching the design and construction methods of the original EStaRS, the team will create an updated version using MathCAD and AutoCAD. The new design will then be built to specification and the team will run preliminary operational tests.
Spring 2016
This semester, the team will be working to design a system to measure headloss in the filter during forward wash and find a way indicate if the bed if fluidized during backwash. At this point in the semester, a manometer system has been set up to indicate headloss in the entire tank and a way to measure fluildization in the sand layer. The rest of the semester, we will be researching the relationships within our data collection and implement our findings into the field. The team will also continue to test the filter's performance while running with PACL and clay to view how the filter would perform in similar field situations.
