The title itself is a mouthful. Nonetheless, there are very important benefits of reverse osmosis water systems to our own health which makes the process very important to our daily lives. In its most simple description reverse osmosis is a filtration process which is often used for purifying water. The process uses membranes with micro-pores which allow the molecules of water to pass through but filter out anything larger.
This way, the pollutants or particles present in the water are not allowed to pass through which results to clean drinking water. The whole filtering process takes longer than other kinds since passing all that water through a super fine membrane takes some time.
There are a lot of households that use this kind of purification system. Typically the purifier includes layers of sediment filters which initially remove particles like rust from the water. The filters usually have different pore sizes and are intended for various kinds of particles. One of the filters is a carbon filter which can trap organic chemicals and chlorine.
And then finally there’s the reverse osmosis filter which is a thin film composite membrane. The combinations of layers of different filters make the purification process more effective. Using for instance carbon filters and reverse osmosis filters ensure that a lot of impurities in the water are removed.
One good thing about reverse osmosis systems is that it does not require any electricity for it to work. Unless you’re using ground water and pumps for your water supply, the normal pressure from taps are enough to push the water through the layers of filters or membranes. Of course, the membranes and filters need to be replaced regularly since sediments and particulates can accumulate rather quickly.
Not only do impurities are removed from the process, but whatever odors the water has are removed as well. Also, unlike other filtration systems, reverse osmosis does not use any chemicals or its filters which lessens any possibility of chemical contaminations. And in the long run, the filtered water can be used for cleaning tiles, sinks, faucets and toilets since the water does not contain any dissolved minerals and metals which can turn out to be harmful even for household equipment like water heaters.
Now despite the advantages, using reverse osmosis filtering systems do have a couple of disadvantages. First is it will need a lot of pressure from the water to push itself through the membrane. Ideally the pressure from the tap should be at 40 psi or greater. If you live in an area where water supply is not reliable having a reverse water osmosis system might prove to be quite the liability.
Another issue is that the membranes used are not able to filter out ultra fine water pollutants like insecticide and pesticide molecules. These kinds of contaminants can still find their way into your drinking water. However, unfortunately because of the fine membranes the process also removes the important minerals present in water which our body needs as well. So it odes not necessarily mean that since the water that comes out of the reverse osmosis process is pure, it is healthy for our use.
Finally, using reverse osmosis for our protection will produce too much waste water because of the process itself. Because of the pressure and the super fine filters, much of the water that passes through the system will not pass through. Gallons of water are wasted for every gallon purified. However, waste water can be channeled back to the ground water.
