The truth about residential reverse osmosis systems
In response to the growing demand for home water filtration systems, a lot of people have chosen to buy and install residential reverse osmosis systems.
After studying the pros and cons of these residential reverse osmosis systems, I came to the conclusion that I should advise against them. Below, I will give you the three top reasons to support my decision. I rank them in terms of importance, the first being the least important.
Reason #1: Because of the way they work, these systems' speed of operation is very low. You see, the way they process water is by using high pressure to push it through a filter which has very small holes, or pores as they are called. The principle is very simple: All that is contained in the water and has smaller molecules than these pores goes through to the other side (the output side), while the rest remains in the input side. In this way, the water gets filtered, as a large range of contaminants (with large molecules) do not make it through to the other side. This whole process is inevitably time consuming, due to the very small size of the pores.
Just to give you a rough indication, in order for one gallon of pure water to be produced, it may take up to three hours. As a consequence of this drawback, installation of residential reverse osmosis systems always requires for a storage tank with capacity 2 to 5 gallons of water.
Therefore, when you buy a reverse osmosis system you should always have in mind that you need the extra available space needed for the storage tank. Also, you should estimate beforehand the maximum demand of running water that you will nedd at your home on an everyday basis, so as to make sure that the system you will install will be able to meet that demand.
Reason #2: The second drawback of residential reverse osmosis systems has to do with their efficiency, i.e the ratio of output to input water. This efficiency is very low, in other words they waste a lot of water. To be more practical, I should say that 1 gallon of purified water corresponds to 3 up to 10 gallons of tap water. What's left in the input side is simply wasted, guided into the drain.
This fact has a direct impact on your bottom line, as your cost per gallon of water is increased because of the higher water consumption. Furthermore, you have to take care of the water drainage, this complicating your installation set up.
Reason #3: While I may agree with you that the reasons I presented so far are not that strong enough to deter you from buying residential reverse osmosis systems, the third one I am sure will make you definitely think otherwise. As I said above, the way that these systems work is by separating water from possible contaminants it might contain, based on their molecular size. While admittedly this method is reasonably successful for a large range of pollutants, the sad truth is that, along with the harmful substances, water is stripped off from essential minerals (magnesium, calcium potassium and so on).
It is worth mentioning that demineralized water is not very appealing to your taste buds. It is flat and tasteless.
But, unfortunately, the drawbacks of drinking demineralized water do not end on just the taste alone. Long time consumption of it can really endanger your health, as experts say. In fact, in their report that was published some time ago and was based on results of a detailed study, the World Health Organization claim that, in order to avoid any health problems, people should never consume water that does not contain minimum levels of essential minerals.
