Abstract
A portable water purification system includes a generally rectangular boxlike chest containing a particulate matter prefilter, a reverse osmosis filter and an activated carbon postfilter unit disposed in a lower base part of the chest. The prefilter, reverse osmosis filter and postfilter units are connected in series by flexible conduits. The chest includes a removable tray section provided with receptacles for receiving a plurality of connector assemblies, a raw water diverter valve, and flexible conduits interconnecting the filter units with the raw water source, a waste water discharge line and connector assemblies for serially connecting a plurality of pure water storage containers comprising conventional plastic milk jug type containers.
Claims16
A portable water purification system usable as a domestic appliance comprising:
- means designed for staged purification of raw tap water to a potable pure condition, including:
- a plurality of flow connected water filter units arranged for seriatim removal of different inpurities contained in raw water to be purified, said filter units including:
- a primary water filter unit having a pressure vessel, means forming a reverse osmosis filter structure in said pressure vessel, a raw water inlet conduit, a pure water outlet conduit and a waste water outlet conduit connected to said pressure vessel, respectively;
- and
- a secondary water filter unit operationally adapted for solids removal;
- raw water connector means for detachable connection to a raw water faucet, and flexible raw water conduit means for conducting raw water from said raw water connector means to said filter units;
- pure water connector means defining a closed system for connection to a pure water storage container, and flexible pure water conduit means interconnecting said pure water connector means with an outlet from said filter units;
- and
- portable storage chest means for containing said filter units, said flexible conduit means and said connector means for storage of said system upon disconnection of said conduit means from said faucet and said storage container, respectively.
A portable water purification system comprising:
- means designed for staged purification of raw tap water to a potable pure condition, including:
- a plurality of flow connected water filter units arranged for seriatim removal of different impurities contained in raw water to be purified, said filter units including:
- a primary filter unit comprising a closed pressure vessel, raw water inlet conduit means, pure water outlet conduit means and waste water outlet conduit means connected to said pressure vessel, respectively;
- a raw water connector for connecting a source of raw water to said primary filter unit through said inlet conduit means;
- a solids type secondary filter unit interposed in said raw water inlet conduit means;
- and
- an adsorbent type secondary filter unit interposed in said pure water outlet conduit means;
- a plurality of container connectors for serially connecting a plurality of storage containers to said pure water outlet conduit for filling said containers in series in a closed system without disconnecting said pure water outlet conduit from any one of said containers;
- and
- portable storage chest means for containing said filter units, said connectors and said conduit means when stored.
A countertop water purification system comprising:
- means designed for purification of raw tap water to a potable pure condition, including:
- an elongated boxlike support chest having a base part including means for supporting at least one filter unit;
- a filter unit including a housing supported in said base part;
- a raw water inlet conduit, a pure water outlet conduit and a waste water outlet conduit connected to said filter unit, respectively;
- a quick release connector assembly connected to one end of said raw water inlet conduit for connecting said filter unit to a source of raw water;
- at least one releasable pure water connector assembly defining a closed system for connecting said pure water outlet conduit to a storage container for conducting pure water thereto;
- a support tray having means thereon for receiving and supporting said conduits and said connector assemblies, said support tray being disposed on said base part and forming a closure for said base part for enclosing said filter unit;
- and
- a cover member removably disposed over said support tray for enclosing said support tray.
