Reverse Osmosis is a water treatment process that removes, cleanses, and separates contaminants from a source water by utilizing pressure to force or push water molecules through a semi-permeable membrane to produce purified drinking water. During this process, the contaminants are filtered out and segregated then flushed away, producing clean and delicious drinking water. Reverse Osmosis is very capable of removing up to 99 percent of 65 different contaminants including lead, fluoride, chlorine, dissolved salts, and much more.
In the reverse osmosis process, there are four stages that water must go through to produce purified drinking water. This source will tell us more of these stages.
The first stage is when water passes through a sediment filter. This is a pre-filter stage that has a primary function of straining out silt, dirt, and sediment. This process prevents these solid materials especially dirt from entering the system and the reaching to the delicate reverse osmosis membranes that can be damaged if the sediment is not screened or the sediment is allowed to reach the RO membranes because it could clog the system or destroy its parts.
The second stage is the carbon filter. This part of the system is responsible and designed to remove chlorine and other contaminants before the water reaches the reverse osmosis membrane. If the chlorine, chemicals, and other contaminants are allowed to reach the reverse osmosis membrane, this could damage this delicate part and will even be requiring repairs and replacement. The presence of carbon in this stage also improves the taste and the odor of your water. The third stage is the reverse osmosis membrane. This is the key component that is designed to allow water through small pores that are responsible for removing water hardness causing ions and cations such as calcium and magnesium and other dissolved minerals, heavy metals, agrochemicals, industrial chemicals, protozoan bacteria, parasites, and debris from organic materials are filtered as well. They have synthetic fibrous polymers wound into a thin film composite about an inlet feed that does this function. Careful consideration is taken into consideration in the production of reverse osmosis systems. Water salinity levels are also removed during this process.
Then the last stage is the polishing filter stage. This will polish off the water to remove any remaining taste and odor in the water. This ensures that you will have an outstanding drinking water. Reverse osmosis technology goes beyond the abilities of typical filtration system using a semipermeable membrane to remove impurities from water. It is a water filtration system is a low-maintenance and a chemical free option to achieve clean, great-tasting water each and every day. It improves taste, odor, and appearance of water by removing contaminants that cause taste and odor problems. It helps you save money and stop the need to purchase bottled water so you can save more and at the same time do your share in saving the environment.
