摘要： A domestic nanofiltration membrane based water purifier without a storage tank. The water purifier according to the present invention uses a nanofiltration membrane filter as a main filtering section and does not have a storage tank for containment of purified water. Although conventional reverse osmosis membrane based water purification systems provide good quality water, they have problems in that installation of the storage tanks due to insufficient flow rate results in the increased volumes of water purifiers, and at the same time, secondary pollution may be caused by microorganism propagation upon prolonged storage. In this regard, the present invention provides a domestic nanofiltration membrane based water purifier without a storage tank, in which a nanofiltration membrane filter with a pore size of approximately 0.1 to 10 nm is used as a main filtering section.
