Reverse Osmosis Filter

Reverse osmosis is a separation process in which everything from the food industry, concentrated fruit juice, water filtration and dialysis, which are used to is used to remove impurities. In this article we will discuss, reverse osmosis and osmosis answer the question: "What does reverse osmosis make" the process of how to filter pollutants from drinking water.

To answer the question, "What is reverse osmosis?" We must first look at osmosis.

Suppose you have a tank with two chambers separated by a very fine sieve, and the pure water from one side of the screen and salt water on the other side. The screen is so beautiful, the salt molecules can not be, but leaves the water molecules. If normal osmosis takes place, the concentration of salt water are slowly diluted with fresh water.

In reverse> Osmosis, hand pressure applied to force the salt water, the water, but leave the salt molecules behind the filter. As the process goes against the natural tendency of the water, it is called reverse osmosis.

When used in reverse osmosis water filter, the screen as a semipermeable membrane. The membrane is thin as a sheet of cellophane with pores so small that only the particles of the size of aWater molecule, it can happen or not.

Because the water is squeezed by the contaminants must be removed from the system on the left. To speed up the process, it may be necessary to reduce the amount of water pressure with the addition of a booster pump to increase the waterline. Even with enough pressure, however, a considerable amount of water still does not pass through the membrane and are lost as waste.

Reverse osmosis systems are very slow and manufacturersWash enough clean water for bathing and washing, is a reminder (with a membrane to keep the pressure) is required.

One advantage of these systems is that they do a great job of cleaning hard water or brackish water, ie water with excessive minerals such as calcium, iron sulfates, lead, magnesium, etc.

The disadvantages include the fact that they need to remove all minerals, including trace elements our bodies, and water, without minerals is slightly sour and stale or flatTasting.

In addition, since cancer seems to thrive in an acidic environment, many doctors recommend drinking demineralized water. Anyone who has one of these systems can be useful to look at minerals.

Another disadvantage is that you do not remove contaminants with a molecular weight of the water. If there is chlorine in water, for example, will not be removed by reverse osmosis, because its molecules are too small. All carcinogenicBy-products of chlorine, chemicals and many organic synthesis, will not be removed.

The EPA recommends that activated carbon filters to remove contaminants such, and should definitely be used in combination with a reverse osmosis system.

Although water is not chlorinated, carbon pre-filter is recommended not to remove volatile organic compounds due to health reasons and to protect the membrane.

So, that's it. A brief explanationof what reverse osmosis is, how it works, and what it removes.

The Good: As you have seen, reverse osmosis systems will do wonders in cleaning up brackish water and water with excessive mineral content and, when used in combination with a carbon filter, delivers very clean water.

The Bad: The process is also bulky, prone to maintenance issues, is more expensive than other filtering technology and delivers a "flat" tasting product some have deemed unhealthy for long term consumption.
