The reverse osmosis central water purifying device and the nanofiltration central water purifying device have the problem of producing concentrated water in the process of preparing purified water due to the limitation of the working principle. For example, the pure wastewater ratio of the traditional reverse osmosis water purifier is 1:3, namely, 1L pure water is produced and 3L concentrated water is produced simultaneously, the produced concentrated water cannot be drunk, and most water purifier manufacturers can choose to directly discharge the concentrated water. This is clearly a waste of water resources.
