The membrane filter preferably receives water through a pump in a screen filter, but could receive water from other sources. The booster pump pumps water from an output of the membrane filter into the pressurized water tank. The water from the membrane filter is preferably pumped through at least one carbon filter for additional filtering. An air compressor is used to inject air into a backwash solution. An auxiliary inlet and an auxiliary outlet are created to receive a removable reverse osmosis filter. An electronic controller includes a touch screen monitor, which provides control of and displays various information concerning the portable water treatment plant. The electronic controller senses the insertion of the reverse osmosis filter into the portable water treatment plant. Chemicals in the cleaning solutions are neutralized before discharge. ## Claims ### Claim 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. ### Claim 2 (depends on 1) The portable water treatment plant of claim 1, further comprising: a measure of chlorine is added to said pressurized water to form a chlorinated solution, an air compressor for adding air to said chlorinated solution. ### Claim 3 (depends on 1) The portable water treatment plant of claim 1 wherein: a recirculation loop is connected between an input and an output of said membrane filter. ### Claim 4 (depends on 1) The portable water treatment plant of claim 1, further comprising: said controller including a touch screen, said touch screen monitors system parameters and displays the system parameters, said touch screen allows a user to modify the operation of said portable water treatment plant. ### Claim 5 (depends on 4) The portable water treatment plant of claim 4, further comprising: said touch screen allows said portable water treatment plant to be monitored through the internet. ### Claim 6 A portable water treatment plant comprising: a membrane filter for filtering water from a source of water;
