Reverse Osmosis Filter

In reverse osmosis water filters were developed in the late fifties, it made sense to apply some of the houses that the technology of individuals. But now we must do everything it can to save water. And most of the waste water through reverse osmosis filter system down. Even the best systems built four gallons of water per liter of drinking water produced. Why would someone pay to empty the water into the drain?

In 1959Researchers at UCLA have been the first to demonstrate that the process of reverse osmosis to remove salt could be used to obtain pure water for the '. There was a big push for this technology during the Kennedy years. The motto was "about the moon and the desert flower." With the support of the Government, the breakthrough came with the production of reverse osmosis water filter with a membrane of cellulose acetate polymer.

The next step was to put thisnew filters, reverse osmosis, in practice. The City of Coalinga, California was the first commercial plant, where the continuous improvement of the selection process. The plant began operating in 1965 6.000 liters per day produced by the local brackish groundwater. This was to be a big improvement for residents, such as drinking water was the first plant was built by truck. The water is about ten times as salty brackish water. A plant wasbuilt in La Jolla next to work on the problems of converting sea water into fresh water.

The discovery of reverse osmosis filter has influenced the whole world. In the Middle East and North Africa desalination plants to produce billions of gallons of water a day cleaning. The process has also been home raised in demineralization.

There are two types of reverse osmosis membranes for domestic filter. They are celluloseTriacetate (CTA) membrane and the Thin Film Composite (TFC) membrane. In deciding to use, it has the ability to filter and chlorine tolerance. The CTA membrane chlorine better tolerated, but only 93% declines in pollution. The TFC / TFM membranes reject 98% of the pollutants, but can be used only with water without chlorine. Most public water supplies are chlorinated. The membrane for reverse osmosis filter that can be done in a numberdifferent geometric configurations. The water pressure forces water molecules through the membrane leaving contaminants behind. This, rinsed now concentrated, impurities in the exhaust.

The average RO system is a set consisting of a pre-filter to remove chlorine and sediment filters, reverse osmosis, a hopper and a carbon post.

better membranes for further researchDesalination, as well as membranes for water recycling systems and remediation of hazardous waste. There is definitely need for this technology.

But it would be a better choice for the individual home systems, which are not wasting water at all. Advances in water filtration technology, the use of reverse osmosis filters useless. Do your research, there is a lot more earth-friendly and economic decisions.
