摘要
A pump (1) extracts contaminated water, sending it through a feedline to a storage tank (2) through an internal sand filter (3). A second pump (4) extracting water from the tank, is followed by a disinfection filter (5) directly ahead of the extraction point (6) for potable water. The first pump is manually-operated using a swinging lever (7). The second pump is a hand-cranked (8) piston-membrane unit. A bypass line (11) is connected around the first pump, using three-way valves (9, 10). The first pump and both of the 3-way valves can be back-washed from the sand filter outlet. Supply tank, sand- and disinfection filters share a common casing (13). A supply tank venting filter (14), is connected to the top of the casing. An overflow line (15) is connected to the upper edge of the storage tank, and discharges into the open. The supply tank base (16) slopes down to its center or edge.
