Hydraulic Reverse Osmosis Water Purification

It continues to astound me how many people buy bottled water just for use in the home. It’s high time that everyone in this area got a proper education, people. You’re throwing away a lot of money, not to mention a lot of time and effort. 

Do you know what “reverse osmosis” refers to? Most people don’t realise that reverse osmosis is the process most commonly used to filter the water in bottled water before it reaches store shelves. It’s a known reality that many people are completely unaware of. 

The benefits of reverse osmosis will become common knowledge very quickly

Reverse osmosis systems for domestic use have only recently become commercially available to consumers. The United States government and large corporations have been its principal customers for purifying non-potable water supplies around the world until quite recently. It was used on large commercial and military ships to disinfect seawater so that it could be safely drunk by people, a practise that continues to this day.

Reverse osmosis (RO) is a more complex process than its common name—filtration—would have you believe. Because it’s easier to visualise in that context, it’s often described as a filter when trying to explain it. Osmosis, for instance, is how our blood carries essential nutrients to every single one of our cells. Even in the tiniest capillaries, blood is able to transport nutrients that are vital to life through the cell membrane and into the cell.

Long ago, researchers developed a technique for desalinizing ocean water by reversing or otherwise taking advantage of the natural osmotic process. Using the same semi-permeable membrane, they found that they could “manufacture” clean water on the side of the membrane that did not have any pressure applied to it by applying sufficient pressure on one side to overcome the natural osmotic pressure of the other side. This was achieved by applying pressure to the unpressured side of the membrane and pumping salt water across the membrane.

Is It Okay to Drink the Reverse Osmosis Water That Was Produced?  

Reverse osmosis purified water poses no health concerns to the consumer.  There is a scientific rationale for why this filtered water is preferable to water with a high mineral (TDS) concentration. Water becomes electrically charged and can carry a small electric current if its total dissolved solids level is high enough (above 50 ppm). High-TDS drinking water has the potential to power an electric lamp when the conditions are just right.  When the TDS of a solution is high, it usually means that there aren’t enough hydrogen atoms to go around. 

The Technological Facet of It

Since the initial reverse osmosis devices were prohibitively expensive for the average homeowner, they were practically never used in private homes before they became widely available. This is typical of the introduction of any new and exciting form of technology.  The membranes’ poor performance resulted in considerable water loss. Recent technical developments have allowed for the emergence of an option that meets the needs of the normal consumer while being more affordable, more effective, and more readily available.
