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.

Brackish water is water that is taken from estuaries and river openings. It salt concentration falls in between fresh water and seawater. Not as pure as fresh water, yet not as salty as seawater. Its mild salty concentration is discouraged for human consumption. To generate purified water from brackish water, a water filtration system relies on a method called "reverse osmosis" for assistance.
A commercial reverse osmosis system complete with pre and post treatment was manufactured and supplied to a major company Antigua & Deps. The system was designed to produce 4500 GPD. From its initial start-up, the Reverse Osmosis machine in Antigua has been working properly with minimal trouble-shooting. The quality reverse osmosis machine was 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".
