What is reverse osmosis?
The phenomenon of osmosis is not a human invention; with it, water is exchanged in all living organisms. Direct or natural osmosis is the process of spontaneous transition of a solvent (usually water) through a semi permeable membrane towards the solution. This is how plants draw water from the soil. In the roots of plants, the salt content is much higher than in the water contained in the soil. Under the influence of osmotic pressure, water penetrates into the plant. Similarly, cells in our body receive water. A cell membrane is a membrane through which water and nutrients are absorbed from a less saline intercellular fluid into a cell cavity filled with a more concentrated solution. Interesting fact. The first effect of osmosis was described back in 1748 by the French abbot Jean-Antoine Noulay. It’s not very clear why, but one evening, not having finished the red wine, he decided to merge the remains into the shell of the pig bladder and hide it in a barrel of water. In the morning the “vessel” was swollen, and the wine was greatly diluted. The priest found that only water penetrated into the bubble from the barrel. So for the first time in history, the phenomenon of osmosis was described. So, nature came up with everything for us, science could only investigate this process and reproduce it. At first, direct osmosis was used to purify or desalinate water. The cleaning process looks like this, on the one hand from the membrane we have sea water, on the other hand a concentrated solution of ammonium carbonate. First, water molecules from sea water penetrate through the membrane under the action of osmotic pressure, then the resulting ammonium solution diluted with filtered water is heated to 60-80 ° C, ammonium escapes, and distillate is obtained at the outlet. However, in the household sector, this method of cleaning is too complicated. In 1970, a fundamentally new method was proposed, based on the already known principle of direct osmosis. The challenge facing the engineers was to get distilled water from the solution without additional iterations. The semi permeable membrane remains the same – it is a synthetic substance that allows only water molecules to pass through and retains dissolved pollutants. Natural osmotic pressure is replaced by artificial hydrostatic pressure. Since water moves in the opposite direction from the solution to the distillate, the method is called reverse osmosis. The simplicity and 100% efficiency of the method became the key to its distribution throughout the world and in all spheres of human activity. In the food industry, industrial Ro plant replaced the heat treatment of concentrated juices and milk powder, which allowed us to preserve useful trace elements in products. Reverse osmosis attracted medicine with a guarantee of complete sterilization of water, because the membrane delays even cholera and hepatitis viruses. Thanks to the use of reverse osmosis for desalination, the availability of drinking water in arid and marine regions has significantly increased. In 2012, Singapore launched a reverse osmosis wastewater treatment project with the subsequent return of the resulting water to the water supply system. Moreover, such water received the highest rating from WHO and USEPA compared to other natural Singapore sources.
