Abstract:
1. A portable water treatment plant comprising: a membrane filter for filtering water from a source of water; a pressurized water tank for storing pressurized water; at least one removable reverse osmosis filter; a first flow path includes water flow from said membrane filter to said at least one removable reverse osmosis filter to be filtered thereby and then delivering the reverse osmosis filtered water into said pressurized water tank; a second flow path includes water flow from said membrane filter to said pressurized water tank without passing through any reverse osmosis filter; at least one valve positioned for receiving water filtered by said membrane filter; a booster pump for pumping water from said membrane filter into one of said pressurized water tank and said at least one removable reverse osmosis filter; and an electronic controller configured to (i) sense the presence of said removable reverse osmosis filter when connected to said portable water treatment plant, and (ii) to operate said at least one valve to direct water flow into said first flow path only when said at least one removable reverse osmosis filter is present instead of into said second flow path.
