What is Reverse Osmosis Water ?

Reverse osmosis water can be both explained in a very technical way, or we can just have the abridged version and move along. However, none can really beat the charm of elaborate explanation along with its every bits and pieces; it makes clarity is even more of a clarity.

However, using too much technical terms will make it tedious and confusing at some point, so we guess we will try our hardest to answer your curiosity by trying to balance both technical aspects of the explanation along with its human terms and abridged version every now and then.

Because the scope of this article is kind of limited and the explanation for this could go on for a very long, drowning, time, so we will give only some salient points that hopefully, will guide you to a better understanding on this matter, and most importantly help you understand closer .



What Is Osmosis ?

Okay, here goes. So first, let’s start from the bits of osmosis term in the name. What in actual heaven is osmosis? So osmosis is the kind of diffusion in which the water molecule and the gradient of concentration occurs and mingled together through the semi permeable membrane included in the system. Confusing? Indeed it is, but we will break it bits by bits so that we will have more ease in understanding this thing.

To start from that point, diffusion is equal to movement of molecules. Speaking from a more technical sphere, it occurs because the molecules from a region with higher concentration move to another region with lower concentration. To shed a more clarity on that, we will explain it using figure. So let’s say that you have a glass of pure water. Now you add salt or sugar into it. Of course, by this point, that said water will not be pure anymore, right?

Next you take a U-tube, not a site to put videos but a component of a machine, with two tubes on both of its edges and a membrane that is semi-permeable in nature. Put one of the solute-filled water on one side, and another pure water on the other side. One of the known attributes of water that is used as a benefit that makes this system possible is that the lower concentration of solvent will try to find its equilibrium state when you apply pressure to it. So cutting the long story short, you apply some sort of pressure to the part where the pure water placed and then it will move, causing the osmotic pressure to happen in its elements.

In the end, it well sort of mingled with its water counterpart and will gradually weaken any of its known solutes and as the result, reversing it to its balanced state once more. This role is also mostly achieved by the fact that it has semi-permeable membranes, which could allow the water to pass through but not ions not larger molecules contained in the water. This osmosis thingy can be stopped, slowed, or even reversed, as the point of the whole thing is, if you just put the right amount the pressure to the concentrated side of the membrane.

If the normal osmosis were to be occurred, the fresh water will simply cross the membrane to neutralize the solution that is concentrated on the other side of the system. However, it is slightly different in the reverse osmosis when the certain pressure is applied on the side of the water that has the concentrated solution to be filtered to the place where the lower concentration occurs, which in turns, make it inevitable to cross the filet boundary of the membrane and actually separating the impurities lies in it rather than just neutralizing it. So it is ‘reverse’ osmosis, where the law is conditioned in certain fashion that makes it possible to happen otherwise.


To give a better understanding on the nature of what is reverse osmosis water filter system can do, probably it is best if you also look on three main stages of filtering process that happens in reverse osmosis. The first one is the pre-filtering which serves to separate water from larger particles. After that one is done, the water will move to the more delicate membrane to separate even smaller particles in the water. After that, the final polish where the water is moved to the holding tank. This final stage is where the remaining odor or taste of the water will be completely wiped off, making it possible for you to drink it or to use it as any other pure water. So does that answering your curiosity on reverse osmosis water? We sure hope it does!
