PURPOSE: A fresh water purification system is provided to improve purifying force by passing through a filtering agent to the water with the fixed speed of a current. CONSTITUTION: A fresh water purification system includes a water supply pipe(10a,10b,10c), an aeration chamber(20), a first barrier(30), a filtering trap(40), and a purified water collection chamber(60). The water supply pipe is installed at the bottom of a pond(1). The water supply pipe collects the purified water. The aeration chamber includes a space for storing the water with self-gravity pressure of the pond. The first barrier includes an inlet(31) which is lower than a limited water level of the pond. The filtering trap includes a filter layer(41,42,43,44,45). |
