Explain Briefly About Filters Present in RO Water Purifier System Reverse Osmosis (RO) is a filtration technique, which needs to be used when the water supplied to a household or locality is high in TDS than the permissible limits. An RO water filter is used to make this water drinkable by removing the dissolved salts and chemicals from it. A water filter using RO has a set of filters designated for different stages in the filtration process. The function of each is explained below: The first component of the system is the water inlet followed by a pump, which exerts pressure on the water to push it through the system. The water is passed through the first filter now.

Sediment Pre-Filter As the water passes through this filter, it is relieved of the suspended impurities i.e. the likes of sand, silt and other similar sediments. The other purpose of this filter is to protect the RO membrane, which would not be able to work efficiently if these impurities are not eradicated.

Carbon Pre-Filter
This pre-filter with activated carbon is installed with the purpose of removing any chlorine or organic components, which could be responsible for damaging the RO membrane. An additional carbon filter can also be installed to work in a similar manner post the RO process. â—?
RO Membrane In the next stage of purification, the water passes through the RO membrane, which is the main component of the system. Once the water passes through this membrane, all the dissolved impurities are left behind. These are mainly the salts and other toxic metals and pesticides. The water received in the storage tank is clean and pure.

Post Filter Between the tank and the faucet, there often lies the last filter of the system, which is generally a carbon filter. This is made a part of the system with the main purpose of removing any odour, which might have been left behind in the water. As a result, the water that flows out from the tap is clean, potable and odour-free.
TDS Controller This is technically not a filter but a very important component of the RO water filter system. WHO permits certain lower and upper limits of TDS in the water. When the purified water reaches the tank, most of the salts would have been removed by reverse osmosis. The TDS
controller is responsible for maintaining sufficient quantities of salts in it as the bodily systems need them. The desired quantities of water are combined from the pre RO stage to maintain these levels of TDS. A water filter for home should be chosen carefully while keeping in mind the TDS levels of the water. If the TDS levels are high, Reverse Osmosis water purifiers using all the above filters is a great option. Today, there are many advanced water purification systems that come with a Mineral RO technology, which helps in retaining the essential minerals in the water. All these technologies in the RO system have the sole purpose of giving you clean, pure water for a healthy life. For more details visit- ​RO Water filter for home
