How RO Systems Treat Salt Water

Drinking salt water is never advisable but in places where clean, drinking water is scarce, it might be the only option. Salt naturally dehydrates the body which is why it would try to get rid of it. Lack of water will eventually lead to serious dehydration symptoms such as dry mouth, headaches, dizziness, rapid heartbeat and low blood pressure. In severe cases, it could even lead to kidney failure as the body can no longer produce urine. Fortunately, through today’s advancement in water treatment technologies, reverse osmosis (RO) systems can desalinate water for safe drinking. Here’s how:

The first step in desalination is the pretreatment in which suspended solids are removed from the water. This is followed by adjusting the pH level and controlling the scaling caused by constituents. After this, the water a pump pressurizes the pretreated water, preparing it for the separation process. During the separation process, the RO system’s semipermeable membrane allows dissolved salts to pass through, separating it from the desalinated water. An RO system’s ability to desalinate water depends largely on what type of reverse osmosis membrane is used.

It is important to note that not all dissolved salts can be completely removed. Small amounts still linger in the water but the end product is now ready and safe for consumption. It might require, however, some few adjustments before it can be stored for use later. For instance, desalinated water’s pH level should be measured first before storing it for later use.
