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.
When I was in the process of selecting a water purification system for my own house, I did my own research on residential reverse osmosis systems. In this article, I will give you below my top three reasons why I should advise you against buying them. I start with the least and finish with the most 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.
As you understand, that extra storage tank will be taken into account when you estimate the space allocated at your home for the installation of the system. In addition, you should carefully dimension the capacity of this tank, in order to make sure that it will meet your maximum demand of water on a day to day basis.
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: And we come to the biggest downside of all, at least in my book. Because of the way that residential reverse osmosis systems work, the minerals (calcium, potassium, magnesium etc) which are existent in tap water are discarded, because they have larger molecules than water and so do not pass the membrane.
Let me say that you can very easily tell when water lacks minerals, or it is demineralized as the exact term goes. It tastes funny, or better yet, it doesn't taste at all! It is flat.
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.
Having said all the above about reverse osmosis systems, my advice to you is that you should consider investigating water multi filtration technology instead. To find relevant information and see what I use, visit my website. - 17274
