The Filtration Team will conduct research on existing foam/bag filtration and granular filtration technology, develop an initial filtration design, conduct experiments to validate design, and produce a final design based on experimental results. The Filtration Team is has currently focusing conducted research on four three possible options: multiSipon-filtration, stacked filters, back wash Aided backwash, backwash clear well, and foam /bag filtration.

Clear Well Filtration

The Clear Well Team's focus is to determine if a gravity driven clear well filter design is feasible technically and economically. A clear well is one of the few options that allows a filter to be cleaned without using electricity. The clear well cleans the filter by backwashing the filter with water stored at a higher elevation in the clear well.
