ABSTRACT:
A portable water purification system (10) includes a portable reservoir (12) for containing a contaminated water supply (14) and a separator module (48) for separating water and water soluble substance permeate from a contaminated water retentate. A permeate outlet (52) is operatively connected to the separator module (48) for releasing water and water soluble substances from the system (10). A return conduit (34) is operatively connected between the separator module (48) and the reservoir (12) for returning contaminated water retentate back to the reservoir (12). A plunger (54) is operatively connected to the reservoir (12) and includes an inlet chamber (32). The plunger draws contaminated water from the reservoir (12) and forces the contaminated water (32) through the separator module (48) so that the permeate flows out the permeate outlet (52) and the retentate flows out the return conduit (36).
