Desalination: Salt Water to Fresh Water Using Reverse Osmosis

It is important to note that desalination of salt water to fresh water with the use of reverse osmosis technology is one of the most reliable processes of water purification. It is widely used in both industrial applications as well as the production of drinkable water. Basically, the main objective is the removal of salt ions and other larger particles to purify the water.
Additionally, the reverse osmosis filtration process comes in handy for the elimination of pathogenic elements like bacteria.

Benefits of Reverse Osmosis Water Filtration

One of the benefits of reverse osmosis is that only little energy is used during the process. There are quite a number of systems out there that can be used in reverse osmosis, and most of them usually are designed to cater for pretreatment process, pressurization, membrane separation, and post treatment stabilization.

Pretreatment Process

The pretreatment process is meant to eliminate suspended solids and also adjust pH-levels, not to mention control scaling. While the pressurization is used to raise the pressure of feed water in order to be compatible with the membrane used. The membrane separation process is equally import in regard to inhibiting the dissolved salts, but at the same time allows desalinated water to flow through the system. Lastly, the stabilization process balances the water’s pH-levels to make it ready for human consumption that will not pose any health risks.

What is Needed

In a nut shell, RO requires the use of a semi-permeable membrane and works with the principle of a transfer of water leaving constituents. It is simply the exact opposite of osmosis. There are quite a number of systems on the market, and versatility of each solely depends on design and how best it works with this particular principle.
