At the moment, our design consists of the following parts:
- two five-gallon buckets to hold the unfiltered and filtered water
- 12 inch foam column, made of PVC pipe
- polyurethane foam, enough to produce 10 inch depth of foam media at 1'' diameter circular cross section
- PVC tubing
- pipe cap
- valve
- two flow accumulators to act as alum and chlorine dosers (optional)
- float valve to control flow (optional)
General Description
Influent water from a stock tank first mixes with alum that is stored in an alum doser. It then enters the filtration column, where the water is filtered through the depth of foam media. The effluent water is then chlorinated and sent through a series of spiral tubing which serves as a rapid mix system. The filtered water is stored in the same bucket that holds the components of the filter. This acts as the distribution system for providing water to the community.
