The best reverse osmosis system makes use of water pressure to pressurize water molecules out of a fine membrane trapping the contaminants behind. It is a systematic process that turns dirty water into clean and safe drinking water. Generally, a reverse osmosis system contains an activated carbon filter, a storage tank, a reverse osmosis membrane and chlorine pre-filter.
The reverse osmosis membrane removes almost all types of contaminants such as dissolve solids, chromium, salt, lead, and heavy metals. On the other hand, the activated carbon filter is there to remove the disinfectants, herbicides, pesticides chlorine and other types of substances that may damage the reverse osmosis membrane. Another feature of the reverse osmosis system that is very important is the sediment pre-filter. Its main role is to remove rust, sand, turbidity and particulates before they make their way into the membrane. It is important to remove some of these contaminants because they can go in and clog the membrane, which may damage it quickly. RO membranes are very expensive to replace, so it is your job to do whatever you can to make it last for a very long time.
Water purification by the reverse osmosis system is done in different stages. The first stage is the sediment stage: This is where rust, sand and other rough particles are removed to prevent them from clogging the RO membrane. As explained above, membranes get damaged easily if rough particles are allowed to clog the pores which might open them up more than it should be. So, this sediment stage is more like a pre-filtration stage.
Carbon stage: Here, chemicals and chlorine which might be dangerous to the TFC membrane are removed. Some RO systems observe multiple carbon stages to take care of excessive chemicals and chlorine in the water.
Reverse osmosis stage: This is where the main job of the best reverse osmosis water system is carried out. The primary instrument used here is the RO membrane. It has tiny pores that allow only water molecules to pass under pressure. Any other contaminant that is bigger than water molecule is filtered out and kept as a waste. The major purification task is carried out here and the water that comes out after this process can be deemed as clean and free of germs.
Remineralization stage: RO filtration method usually filters out the necessary minerals needed by the body. This stage tries to re-introduce these minerals using magnesium and calcium to introduce healthy minerals, improve taste and balance the PH levels.
Storage tank: This is where the filtered water is stored and ready for consumption. The storage tank contains pressurized substance that can force the water out into the faucet when it is opened. This makes sure that your cup gets easily filled without waiting for eternity to get a cup of water. To keep the tank free of bacteria, it is recommended that you wash the tank about twice a year. This will remove any bacteria that may be hanging in the tank.
The above is the basic idea behind the filtration of water using the reverse osmosis system. This is one of the safest ways to drink high quality water free of germs and contaminants. There are different types of reverse osmosis systems as they range in design, brand and quality. If you intend to buy one for your family, select the one with the required number of filtration stages to get clean and mineral rich water. Also, you should consider the best quality model since it will minimize the gallons of waste water while providing pure and safe drinking water for your family.
