How RO Works

You might have installed a Kent RO water purified and have been given a fine piece of demonstration of using the filter, but at the same time, you must be aware about how the filter works inside, to purify your water and deliver the kind of water you desire. This article will inform you about the various stages that RO filters implement to clean water and give healthy and tasty water, ideal for drinking.

In order to know how RO filters work, you should first know what RO is. It is Reverse Osmosis, a process by which high pressure reverse osmosis pumps are used to desalinate water and convert hard water into soft water. It happens through a semi-permeable membrane, present in the filters. The RO process also eliminates dissolved salts, impurities and TDS. TDS stand for Total Dissolved Salts and include organic and inorganic particles and chemicals. It is an ideal process by which brackish water is treated to form drinking water that is consumed by you and your family.

By now, you have developed a basic idea about what RO conception is. So next time you go and purchase a new filter or exchange your current one, you can be more conscious about the process existing in the filers. Having a firm conception about RO, let’s move to the stages by which RO purifies impure water into the purest form.

Step 1: The first step deals with Ion Exchange Water Softener. At the preliminary stage, RO systems remove minerals such as calcium, magnesium and other similar impurities. The presence of these minerals leads to the formation of hard water, which is unfit for drinking and consumption. Hard water is therefore treated to form soft water. At this step, water gets smoothened and softened. It gets conditioned for the actual RO process to start in further steps.

Step 2: The second step relies upon the Activated Charcoal Filter. This filter mainly works to eradicate all microscopic impurities and particles from water. Once water is conditioned in the previous step; the charcoal filter gets activated automatically. The filter works to remove bad taste and odour from water. It also eliminates harmful bacteria and micro-organisms. In addition, chlorine also gets removed completely at this step. Organic and inorganic contaminants such as sewage, harmful industrial solvents, fuel by-products, decaying materials are treated by RO and removed at the end of the stage.

Step 3: At this step, the Five Micron Fiber Filter starts its action. The fiber filter is the sediment filter that helps in removing all suspended particles from water. You can get this filter in two types: nominal and absolute. Where nominal 5 micron fiber filter traps about 85% of particles, of 5 micron size and larger sizes; the absolute filter engulfs 99.9% of the 5 micron and larger size particles. The absolute filter is more preferred, for this reason. The fiber filters also come in various materials, some of them being, wound string or cord, polyester, ceramic, polypropylene, cellulose, glass fiber and cotton.

Step 4: The above steps ensure you that water is free from all pollutants, particles and TDS (Total Dissolved Impurities). The RO system now starts working. It removes about 98.7% of remaining impurities containing bacteria and parasites that result in creating health disorders and diseases. These impurities may also contain lead, mercury, copper, asbestos, nitrate, arsenic, barium, fluoride and other hard elements and metals.

Step 5: This is the final step where ozonation takes place. Ozone gets added to the water treatment process. It aids in reducing iron, manganese and sulfur without any added chemicals, owing to its oxidizing properties. Ozone is also responsible for imparting healthy taste and smell that you desire from pure drinking water. Water gets purified and refined, with zero percent bacteria. Pure water gets stored in the storage filter, ready to be bottled.

Ozonation is not compulsory in every household RO. It may be required in commercial RO.

So, you are educated about how your RO filters and purifiers work to give you good quality water. You have become aware and confident about your filters and purifiers. You also know how an ideal RO system works to fight with impurities and serve you with purest form of drinking water. Therefore, you can fully rely on your filters and take decisions about your filters.
