Purifying Water via High Water Pressure: How Reverse Osmosis Works

The process of reverse osmosis purification has been used for water since the early 1960’s. Originally reverse osmosis was used for the desalinization of sea water. Now reverse osmosis systems produce a hundred thousand tons of water worldwide every day. Modern improvements to the systems have made it possible to implement reverse osmosis systems in the home. Water obtained from a reverse osmosis system has a unique degree of purity. This is because of the effective reverse osmosis process.
