REVERSE OSMOSIS WATER PURIFIER

摘要

PURPOSE: Provided is a reverse osmosis purifier being capable of preventing water quality degradation at an early stage of purification. CONSTITUTION: The water purifier comprises a sedimentation filter (20), a pretreatment filter (26), a main filter (28) and a post treatment carbon filter (32), wherein the filters are arranged in turn, a valve (40) for intake of the final filtration passing out the post treatment carbon filter (32), a concentrated water discharge pipe (50) connected to the main filter (28) for discharging concentrated water, and a circulation pipe (60) for circulating the final filtration to the pretreatment filter (26) so that the circulated water is discharged through the concentrated water discharge pipe (50) via the main filter (28) when the valve (40) is closed.
