The process of reverse osmosis deals with the use of a high pressure pump which applies extreme pressure to the high saline concentrated side of a semi-porous membrane, combatting a natural process called "Osmosis". Naturally, osmosis transports salt through a semi-porous membrane from a region with low saline concentration to a region with high saline concentration. Its goal is to gain an equal quantity of saline concentration on both sides of the membrane. With the use of the high pressure pump, reverse osmosis comes in to direct osmosis to the opposite direction. The pump applies high pressure to the highly concentrated saline side of the membrane, pushing salty water and other impurities across the membrane, only allowing water molecules to flow through. Salt and the impurities are rejected and later thrown into the drain on the concentrate side. In the end, we obtain purified water with 99% less dissolved salts on the permeate side of the membrane.

Estuaries and river openings are places where brackish water can be found. This type of water lies in between fresh water and seawater. It’s not as clean as fresh water, yet not so highly concentrated in salt as seawater. Even if it has a mild salt concentration, it is still not encouraged for consumption.
A Reverse Osmosis system complete with pre and post treatment to a major company in CA, USA. From its initial start-up, the machine has been working properly with minimal trouble-shooting. A quality reverse osmosis machine is designed to deliver high quality service by removing massive amounts of salt and other impurities from wells, lakes, rivers, and the ocean through a process called 'reverse osmosis".
