Reverse osmosis drinking systems are known as the revolutionary methods for water filtration. Many have long sought an efficient water filtration system that can turn salt water into something potable, and the RO system is said to be the answer to that search.
Reverse osmosis systems are highly effective in filtering your water because the holes of their filter allow only the smallest of molecules, such as that of water, to pass through.
What is Reverse Osmosis?
Reverse osmosis works like this: picture an empty fish tank and fill it with pure water. Then divide the tank by placing a semi-permeable membrane right at the middle. Now, add sand to one side of the tank. Now you have a water-filled tank that’s more concentrated on one side of the filter than the other.
The laws of nature would tell you that for those two sides to co-exist, they have to be of equal concentrations. Since the sand cannot pass through the semi-permeable membrane, the only way for these two solutions to attain equal concentrations is for the water on the less concentrated side to go to the side that’s more concentrated. That process is known as osmosis.
In reverse osmosis, the natural process of equaling concentrations is counteracted using pressure. The presence of constant pressure on the more concentrated side means that the water that is pushed towards the other side can no longer come back. Hence, you can observe that the sand stays on one side, and the water on the other side is clean.
How Do RO Drinking Systems Work in a Home?
Reverse osmosis drinking systems work in your home in several steps. First, the tap water flows through a sediment filter that removes large particles such as rust and dirt. If you have a chlorinated water supply, the water is filtered through a carbon filter. The carbon filter is also there to absorb other toxins that can pass through the initial filter.
Next is the reverse-osmosis stage. Here, a thin film composite (TFC) membrane is used to filter out the remaining contaminants in the water. If you have a reverse osmosis tank system, then the water is stored inside a tank. If you have a tank less RO system, then the water stays in the pipes. The filtered contaminants, on the other hand, are flushed down your drain pipe along with some excess water.
Reverse osmosis systems require a working pressure of at least 20-psi, so you may want to buy an RO booster pump if your water pressure is less than the required working pressure.
Is Reverse Osmosis System the Best Water Filtration Option?
All water filtration systems have their advantages and disadvantages. The advantage of using a reverse osmosis system is that it’s very good at what it does. However, that can also be a disadvantage, because the RO system filters water so well, it has a tendency to filter out good minerals such as calcium and magnesium
Another disadvantage of this system is it can be costly. The pumps need energy to work so they have a tendency to add to your power bill. This system also has water wastage of about 2-4 gallons per gallon of pure water you make.
Reverse osmosis drinking systems are excellent water filtration systems and they certainly help in keeping harmful bacteria, parasites, and toxins from reaching your body. Some people will tell you that you can’t put a value on your health. But if you’re really concerned about the costs, then it’s still best to talk to your local RO system dealer about your options.
