Sodium, fluoride, copper, lead, are among the contaminants that may be found in water and which can be harmful as well as lead to bad odor and taste to water. Filtration systems of different types can help remove such contaminants. The most preferred filtration systems are the reverse osmosis systems. RO systems help reduce most contaminants and improve taste and quality of water also. Among the effective and popular systems are home five stage water purification systems to ensure that you get clean, pure and fresh drinking water for the entire household.
The home five stage water purification systems for RO systems effectively remove a large number of contaminants. Commonly there are sediment pre-filter, carbon block pre-filter, RO membranes which are a part of the five stage purification. 5 stage RO systems from Multi-Pure, PUR, Brita, GE and so on include similar stages. You can feel assured of getting disinfected water free from most contaminants at the end of the process.
The sediment pre-filter is commonly used during the first stage. It has the ability to remove particulates, sediments, sand particles of mostly up to 5 microns. It ensures that the appearance of water improves with the particulates removed. Sediment filters are replaced preferably in about 6 months. High quality carbon block pre-filters are used in second stage. They are able to remove contaminants like Trihalomethanes, pesticides, herbicides, chlorine, organic chemicals, lead and aluminum. It helps further reduction in bad odor and taste of water. A secondary carbon pre-filter that provides effective filtration is at work in third stage. It enables improved membrane performance which ensures that chlorine and other such contaminants are reduced.
A TFC high capacity reverse osmosis membrane in the fourth stage helps remove unwanted inorganic impurities, nitrates, fluoride, salt and certain heavy metals. The life of the osmosis membrane is about 2 years and can process up to 50 gallons per day. The Carbon post filter in the fifth stage helps remove whatever contaminants remain even after four stages. It may be able to intercept particles as small as 0.5 micron. The process involves electro-kinetic adsorption of particles by attracting negative ions of certain chemicals, heavy metals, etc. This filter is preferably changed in about a year.
If you have home five stage water purification systems you can experience a substantial reduction in contamination due to arsenic, asbestos, cadmium, barium, fluoride, copper, giardia, cryptosporidium, entamoeba, toxoplasma, selenium, turbidity and nitrate. VOCs like Atrazine, benzene, carbofuran, endrin, dinoseb, lindane, and styrene are also reduced to a large extent.
The water need not have all contaminants in all places, RO systems are designed with an ability to remove them if and where they exist. Understand and analyze what pollutants are present and need to be removed. Considering the contaminants present you may be making a great choice buying home five stage water purification system. Timely maintenance and replacement of filters ensures quality of purification systems. You can feel relaxed and assured of getting clean and pure water for all purposes.
