RO Membranes- The Benefits

Until recently it was believed that the reverse osmosis water filter was the best method for purifying water, but the most up to date studies show that the natural minerals and metals removed by reverse osmosis actually occur naturally in the water and have a beneficial impact on human health. So what is the alternative? The most technologically advanced system is the carbon based filtration system that removes harmful chemicals while leaving minerals and natural metals intact. The chemicals that do get removed are organic and synthetic organic pollutants such as pesticides, agricultural runoff, and household cleansers.If you wish to learn more about this, visit ro membranes.

These substances are not only carcinogenic but have been scientifically proven to be a factor in the onset of degenerative diseases of the nervous system. There has been a huge increase in these types of diseases since the dawn of the industrial era, and the reverse osmosis water filters do nothing to address this issue.

You might be thinking that it would be good to remove both the chemicals and the minerals and metals, but nothing could be further from the truth. In fact, these substances occur naturally not only in all the water of the earth but also in the make-up of our own bodies. There is no such thing as de-mineralized water, except in the cases where humans have removed them. If all the water of the earth contains minerals and our bodies are 70 percent of human bodies are made of this same water, then it makes absolutely no sense at all to employ the reverse osmosis water filter, which removes the very substances that need to be there.

Furthermore, by removing the minerals and metals, the reverse osmosis water filters actually take away the majority of what makes water tastes good. Now let’s look at this more in-depth. Water that is saturated with chlorine, such as that which flows from your tap, tastes a lot like pool water, and who wants to drink that? On the other hand, water that has been through a reverse osmosis water filter tastes like nothing at all. But that isn’t good either, because the chemicals that are the most harmful are completely tasteless as well as colorless once they leave the treatment plant. Carbon filters purify water of these invisible chemicals without stripping water of taste or healthy minerals.

The difference between carbon filters and reverse osmosis water filters is the method of filtration. The reverse osmosis water filter removes particles based on their relative molecular size, and since minerals and metals are larger than chemicals, the minerals and metals get stuck while the chemicals flow right through. Carbon filters bond chemically with the organics and synthetic organics which come from pesticides, agricultural runoff, and household and industrial waste, thus not allowing them to pass through into your glass.

Another unexpected disadvantage of the reverse osmosis water filter is that it is very wasteful. Because of the nature of the process, for every gallon of filtered water produced by reverse osmosis, two to three gallons get wasted. Activated carbon filters do not waste water in this way, and so through carbon filtration there is not only better water but more water for us to drink.

The pitcher style filtration systems use carbon filters rather than reverse osmosis water filters, and they have become popular in recent years, because they require little initial expenditure. Unfortunately, these systems are quite expensive in the long run because of the amount of filling, emptying, and filter changing that is required.

The best filtration system based on activated carbon is one that either filters the entire house or is attached to the faucet for filtered water right from the tap. Be careful, these types of systems can still use a reverse osmosis water filter, but the less expensive and more effective activated carbon filtration systems are easy to install, easy to maintain, and cost less than ten cents per gallon of water used.
