RO Water System
Most people today feel safe that the water they are using for drinking is safe. This may be true for people that obtain their water source from their Municipality. However, the water received is not 100% guaranteed to be clean. People using water from private sources such as wells are at an even higher risk of drinking contaminated and unsafe water.RO Water System
units are used to filter and flush away contaminants in the water.
How do RO Water Systems Work?
The water purification process of Reverse Osmosis is done by forcing water through a plastic membrane. The membrane is small and only allows water molecules to pass through. Larger compounds that may be found in the water are rejected and do not continue through the system. After the water has passed through the membrane, it then goes through a special filter. The filter is made to get rid of dangerous chemicals such as; chlorine, mercury, copper, chromium, and even pesticides. When the water has been filtered it is then stored in a water tank until it is ready for use. The water will go through a carbon filter just before use to enhance the waters’ taste.
What are RO Systems Used For?
Although Reverse Osmosis water systems are used to purify water, it is necessary that the water is first evaluated. Water sources such as wells need to be tested for other types of water contaminants such as microorganisms. Once it has been proven that the water is safe to drink you can further enhance the quality and safeness of the water by using a RO Water System. Like many other water filtering systems, Reverse Osmosis is great for purifying untreated sources of water, but is not completely effective against microbiological contamination.
Benefits of Using RO Water System
RO water systems are a lot more efficient when compared to other water filtrating systems. An approximate 3 gallons are used to obtain 1 gallon of purified water with Reverse Osmosis. This type of water filtration allows water in your home to be mineral-free. As most of us know, certain minerals can be harmful to our health. Untreated water commonly contains minerals such as; lead, manganese, salt, calcium, and iron. Minerals are not the only hazard; chemicals such as fluoride are also often found in untreated water.
Choosing the Right RO Water System
One important thing to consider when purchasing a RO system is selecting between a CTA or TFC unit. A cellulose triacetate membrane (CTA) uses an organic membrane that is more susceptible to bacterial growth. The thin film composite (TFC) is made from inorganic material and is not prone to growing bacteria. While there are many more types of RO systems to choose from, CTA and TFC units are among the more common ones. Another thing to remember while looking for the ideal RO system is if you want one that includes a tank. Tanks are used for storing filtered water, but can take up a lot of room and run a bit slower. Systems without tanks usually work at a faster speed and are more compact. Lastly, do not forget to search for a system that is efficient. Some units only purify 1 gallon of water per every 6 gallons used. This makes the efficiency rate less than 15%. Ideally, each gallon should only use 2-4 gallons of unpurified water.
