an eco-friendly reverse osmosis based water purifier having zero waste water discharge

摘要

The present invention relates to a eco friendly reverse osmosis based water purifier having zero waste water discharge comprising wherein at least one reverse osmosis (RO) membrane and flow restricting means are provided along with and at least one water chamber divided in two part construction or two separate chambers wherein one part or one chamber is for collecting purified water through reverse osmosis membrane and another part or other chamber is for collecting the discharged waste water from RO membrane. Also the present invention relates to a method for performing the water purification by a reverse osmosis based water purifier wherein firstly subjecting the water to reverse osmosis membrane and flow restricting means and collecting the purified water and discharged waste water in separate chambers or in two different parts of water purifier. Also, the present invention relates to a reverse osmosis based water purifier wherein the flow restricting mean is provided with a solenoid valve disposed across the flow restricting mean and operationally configured with the controller with or without an electronic control unit, so as to achieve the flushing of RO membrane at different desired time intervals.
