Working Of The Best RO Water Purifier
Before you start shuffling through the various befitting options, it’s important to develop a brief understanding of how reverse osmosis works. Once you know the basics of the RO filtration process, it will become easier for you to grab the best RO water purifiers. The following section explains the same.
Working
Water has the tendency to move from a region of lower concentration to a region of higher concentration when separated by a semipermeable membrane. This is called osmosis. Reverse osmosis is the process when water moves from higher concentration to lower concentration.
For reverse osmosis to be possible, a pump is used for pushing water through the semipermeable, or RO, membrane. The RO process starts with first passing the water via a semipermeable membrane.
Doing so results in trapping chemical and heavy metal impurities – such as arsenic, mercury, and pesticide residues – by the RO membrane. The same membrane also captures biological impurities, like bacteria and viruses.
In the subsequent step, the water is separated into two sections; impure or non-drinkable and pure or filtered. The non-drinkable water is drained out while the filtered water comes out or passes to the next stage of the filtration, such as to the UV chamber in a RO+UV water purifier.
Now, you know exactly how a RO water filter works. As such, you are now ready to set out to hunt for the top RO water purifier in India.
The main advantage of using a sediment filter is enhancing the work-life of the RO membrane. This is because bigger impurities are dealt by the sediment filter on its own, thus, freeing the RO membrane from assuming the same task.
