WATER PURIFICATION DEVICE AND WATER PURIFICATION METHOD

摘要

A water purification device and a water purification method thereof are provided to improve of permeability of a water molecule by dropping the pressure at the portion at which water penetrating a reverse osmosis membrane exists. A reservoir tank(10) embodies a reverse osmosis membrane(1), and a first reservoir unit(11) and a second reservoir(12) are classified at the reservoir tank, and the first reservoir keeps the water before purification by the reverse osmosis membrane. The second reservoir keeps the water after the purification. A pressure enhancement unit(20) sucks the inner air of the second reservoir to increase the amount of the purified water.
