Low Flow Stacked Rapid Sand Filtration
| Excerpt |
|---|
Low Flow 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. |
Spring 2014
This semester, the team aims to complete fabrication of the 30 cm diameter LFSRSF, which includes a simplified hydraulic control system. The team will add slotted pipes and sand to the filter column, as well as pipe stubs to the inlet and outlet tanks. They will also build a water recycling system to facilitate hydraulic testing of the filter. Testing will involve evaluating the headloss necessary to fluidize the sand bed of the filter during clean and clogged conditions, determining the head required to initiate backwash, and measuring the flow distribution between filter layers. The team will also simplify the sand drain design and and develop a better method to open and shut it. Finally, the team will optimize pipe sizes and elevation of the inlet and outlet tanks to improve access and efficiency.

This system was tested in Honduras in January 2013.
