A water purification system includes a first reverse osmosis device, and a water storage tank including a tank inlet and a tank outlet, the tank inlet configured to receive a permeate of the first reverse osmosis device. The system also includes a second reverse osmosis device including an inlet that is connected to the tank outlet and an outlet that releases a permeate of the second reverse osmosis device. The system provides treated water having a purity of about 0 to 20 ppm, which is sufficiently pure to provide spot-free washing and/or rinsing of objects such as vehicles, buildings and windows. |
