Are you considering buying a reverse osmosis filtration system, but you are unsure how it works? Do you wonder what reverse osmosis is, or are you concerned about drinking reverse osmosis water?
It may have been a long time since your ninth-grade biology class. Therefore, the term osmosis might be familiar, but you forgot what the process of reverse osmosis is in water filtration.
Understanding the difficulty with some of these terms, we figured we would refresh your memory on reverse osmosis filtration and the advantages and disadvantages of reverse osmosis water filtration. Therefore, you can decide if a reverse osmosis system is suitable for your home without returning to high school science class.
What Is Reverse Osmosis Filtration?
Reverse osmosis is one of the most valuable forms of water filtration. Unlike chemical or carbon filtration systems, which utilize specific materials to draw or directly target the contaminants in the water. Therefore, reverse osmosis works by forcing water through a microscopically thin filter textile.
The semi-permeable membrane has a pore size of approximately 0.0001 microns. Therefore the membrane effectively only permits the small water molecules through and catching any larger molecules of contaminants, organic materials, or even salt.
The utilization of reverse osmosis use is found in many governments, commercial, military, and even residential applications designed to desalinate seawater and reduce high chemical contaminant materials such as heavy metals.
How Does Reverse Osmosis Water Filtration Work?
Professional osmosis filtration occurs the process by which molecules pass through a specialized membrane. The water passes from a weaker-concentrated solution into a stronger-concentrated solution. The movement continues until both solutions' concentration reaches equilibrium.
Reverse osmosis filtration is the identical elemental osmosis process. It thoroughly applies, adding higher pressure to drive the water molecules out of the more robust contaminated solution and into the more pure water solution.
Reverse osmosis removes the obvious visual contaminants such as sediment because of the microscopic pores on the semi-permeable membrane filter. However, the process also removes more significant organic material and dissolved substances from within the water.
Reverse osmosis will remove beneficial minerals in water because the RO water filtration treatment is exceptionally effective.
Reverse osmosis does not demand thermal energy but utilizes extremely high pressure. For example:
Brackish water is saltier than fresh water. However, this saline water is not as salty as seawater. In order to remove salt from brackish water, reverse osmosis requires between 200 and 400 psi to force water through a reverse osmosis membrane. Thus the membrane extracts the salt.
For reference, the median water pressure in a suburban home is approximately 40 and 45 psi.
Benefits of Reverse Osmosis Water Filtration
Nearly two million Americans live without direct access to safe drinking water. However, another 40% of Americans further filter their tap water at home. Water filtration systems have become an essential part of many U.S. households.
Though many cities and towns already use reverse osmosis systems for municipal water. Therefore, in most places in the U.S., tap water is safe to drink, and many homeowners seek additional water purification to ensure the water they drink is safe. Some of the advantages of a reverse osmosis water filtration system comprise:
-
Reverse Osmosis Filters Almost All Contaminants
Unlike other setups of water filtration, reverse osmosis is regarded as one of the most all-around effective methods of eliminating water contaminants. Even residential-grade reverse osmosis filters can extract up to 99% of lead, asbestos, and 82 other contaminants.
Reverse osmosis systems removed the need for water advisories in neighborhoods worldwide by safely treating the drinking water where conventional water filtration systems did not function.
The microscopic qualities of a reverse osmosis filter membrane can filter out the larger contaminants and release dissolved substances and minerals from the water. Therefore, this occurs because the membrane essentially strips the water down to essential molecules as it passes through.
-
Safer and More Environment Friendly compared to Bottled Water.
For communities where the only other drinking water option comes from disposable plastic bottles, reverse osmosis may be safer and more environmentally friendly. However, reverse osmosis wastes a significant amount of water. The piling of plastic water bottles in landfills pollutes the environment. During the production of plastic, carbon emissions pollute the air.

Mineral-Less Water May Be Necessary for Specific Uses
Ultra-purified reverse osmosis water may be necessary for households with clean tap water. Specific water uses may aid from water filtered through reverse osmosis. For example, chefs have observed water filtered with reverse osmosis produces better tasting meals since it lacks the presence of minerals.
Pet owners who raise fish and coral in home aquariums may require a reverse osmosis system to provide their aquatic pets with the purest water, free of human contaminants.
Alternatives to Reverse Osmosis Water Filtration
While reverse osmosis filtration is undoubtedly one of the most effective forms of water filtration available. Therefore, it might not be the most suitable option for homeowners. Especially where tap water is already potable.
If you are unfamiliar with the term potable, it means drinkable according to WHO, EU, and EPA standards and of significantly heightened quality.
Rather, homeowners with potable tap water should contemplate a more straightforward decision with efficient filtration systems designed to improve the taste. Therefore they will remove the risk of contaminants that may still be present in the tap water. One of the best choices for homeowners is activated carbon filters which trap pollutants in the activated carbon as the water passes.
These systems can be installed by almost anyone and are affordable. They also do not waste as much water and still permit the water to maintain healthy minerals.
The Bottom Line
Reverse osmosis water filtration is one of the most practical forms of water filtration available today. Still, the design of the reverse osmosis filtrations system provides fresh water. Therefore, desalinating ocean water makes it drinkable in areas where safe water is scarce. On a smaller, residential scale, reverse osmosis is probably excessive in most scenarios, mainly because municipal water is secure to consume in Europe and North America. It is wise to choose a professional water filter manufacturer who has decades of producing experience, I recommend you MSPure, their customers are all over the world, it is worth to give it a shot.
