Is Reverse Osmosis Bad for Our Health? May 11, 2014

Although reverse osmosis offers clean water the health concerns that hound the filtered water still remains an issue today. Those who sell reverse osmosis products would argue otherwise and insist that they have no health related concerns regarding the water that passed through the filtration process.

But recent studies have shown that reverse osmosis can be bad for our health or at the very least is not really guaranteed as manufacturers or users of the system have claimed. The main reason behind this conclusion is that reverse osmosis is able to filter the natural minerals that water contains. These minerals apparently are quite important to our body and contribute a lot to our health.

Reverse osmosis works by forcing a solvent by applying pressure from an area of high solute concentration through a semi-permeable membrane to an area of low solute concentration. By doing so, the membrane allows the water being pushed by the pressure to pass through and prevents larger particles such as salt, for example in seawater. The reverse osmosis system actually uses several numbers of stages which incorporates combinations of various kinds of filters.

The first layer of filter usually uses a sediment type which prevents rust and calcium carbonate to pass through. An activated carbon filter is then next. With this one organic chemicals and chlorine are trapped. The water then passes through a reverse osmosis filter made up of thin composite membrane. Then after that one would find another layer carbon filter which is there to ensure that any particles that was able to push their way through is prevented from going further.

You can now see clearly where the reverse osmosis process has “overdone” the filtering. Unlike carbon filters, reverse osmosis removes any molecules larger than water from passing through. Unfortunately, the naturally occurring minerals are larger than water molecules which therefore are trapped by the reverse osmosis membrane.

And what’s more unfortunate is the fact that harmful substances like those found in fertilizer and pesticide runoffs are smaller than water molecules and so are just able to pass through the membrane quite easily. These contaminants are known to cause cancer and other degenerative diseases and should be the ones being filtered out. Some studies have found out that reverse osmosis is unable to filter more than 2,000 toxins found in tap water.

Aside from the health issue, wastage is also a problem with reverse osmosis. The process actually wastes a lot of water. For a gallon of purified water, around two or three gallons are being wasted and cannot be recycled.

Nonetheless, if drinking water produced from reverse osmosis is not as healthy as one might thing, other uses of reverse osmosis has proven to be quite effective. People undergoing kidney dialysis uses water from reverse osmosis to remove waste products in the body. The pharmaceutical industry also uses reverse osmosis in the various process of drug manufacturing.

However, despite the advantages reverse osmosis might have it is apparent that other kinds of water treatment offer better alternatives in producing clean, drinking water. Indeed, reverse osmosis can be bad for our health and it would be better to settle with newer and more advanced ways of water purification.

These newer systems leave minerals intact and instead remove all the organic and synthetic pollutants like those in pesticides, fertilizers and household cleansers.

Review of Osmosis to Explain Reverse Osmosis May 10, 2014

Have you heard about reverse osmosis? It should truly be a useful and advantageous process of liquid purification because more and more industries are using it. Around the world, the importance of reverse osmosis is also becoming more emphasized. As many experts say, the process holds a lot of potential. It could be a system that could eventually bring about aid and redemption. But what exactly is it? Why is it truly effective? Could it be done using improvised setups? How does it work?

It would just be impossible to understand reverse osmosis without first understanding normal osmosis, where it is derived from. As you could infer, reverse osmosis is only an opposite take of the usual process of osmosis. The dictionary defines osmosis as a natural movement of solvent molecules through semi-permeable membranes so that they could transfer into the side where there is there is lower concentration of solution. In the process, concentration on different sides is equalized so that in the end, there would be no difference on concentration. Osmosis naturally stops the moment such equality of concentration is achieved.

Semi-permeable membranes are membranes that are serving as boundaries between two regions. They are structures where molecules could pass through. Example is a saran wrap, which looks impermeable but is actually permeable. Other good examples are cell walls and intestines. There are very small pores that could allow entry of very miniscule molecules of water. Such pores are too small that they do not allow passage of other liquid molecules and other bodies. Gore-tex fabric could also be an example.

In reality, osmosis is the very same reason why consuming or drinking salty water is very dangerous. Drinking seawater or ocean water could kill anyone, especially if there is much volume consumed. When you do so, the salty water would be temporarily stored into the stomach. Natural osmotic pressure would work and begin drawing water from other parts of the body so that your body would be able to dilute the amount of salt molecules that are stored in the stomach. When the process goes on continuously, you would eventually dehydrate, which could lead to death. It could take only a few minutes or hours for the body to complete the process. This is one of the reasons why many people who drown in sea die.

Reverse osmosis is the exact opposite of the natural osmosis process. The idea is for the semi-permeable membrane to serve as a fine filter that would create safe and potable drinking water out of the contaminated water. This process could very much be illustrated through desalination. Salty water is stored in one side of a membrane, while the less salty is on the other. Pressure would be applied to stop and later reverse the natural osmotic process. Usually, this setup would require much pressure and would take a long time to complete. But there is no doubt that it would truly and effectively work.

Reverse osmosis is now widely used as a process of purifying water. It is also the same concept used in dialysis. Many industries are also starting to use reverse osmosis in their operations. Even disinfection activities could now use this helpful and useful process.

There is no doubt that in the future, many devices that facilitate the process would be more widely available for any household to use.
