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 boxcolumn, as well as pipe stubs to the inlet and outlet tanks. They will also build a recycle water source 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 and sizing of the filter inlet and outlet tanks to improve access and efficiency. |
