Lately we hear more and more often about reverse osmosis water purifiers, particular devices capable of filtering the water that flows from the taps, eliminating all harmful and polluting substances.
Purifiers have spread very quickly, so much so that it is possible to choose different types and various designs so that they can be inserted in any context, also acting as furnishing components for the kitchen. The main advantage of purifiers is precisely that of guaranteeing clean, fresh, and sparkling water without necessarily going to the supermarket, with significant benefits for health and also for the wallet.
Let’s try to understand more about water purifiers by analyzing every single feature.
What is reverse osmosis?
Reverse osmosis is a process that force the passage of solvent molecules from the more concentrated solution to less concentrated solution.
In practice, the water is “pushed” through a membrane, capable of retaining the polluting molecules and letting the pure ones flow out. It is an extremely sophisticated water filtration technique used for domestic systems, but also for offices, bars, and catering establishments.
Reverse osmosis is mainly used for water treatment, but also for desalination and for the removal of phosphates, calcium, heavy metals, radioactive materials, pesticides, and polluting molecules in general.
The safety of some of the best RO Water purifier in India has been tested for some time, so these devices are finding widespread use in Indian homes.
What does reverse osmosis eliminate?
Reverse osmosis is able to eliminate all the impurities present in the water, which naturally then flow into our body. The aqueducts, despite being very controlled, contain some dangerous substances, in particular the so-called perfluorates. These are chemical substances, generally industrial waste that infiltrate the aquifers and are therefore present in the water that flows from the tap.
Reverse osmosis eliminates all harmful substances in suspension, purifying the water to 99% of:
- heavy metals
In addition, reverse osmosis eliminates mineral salts, such as calcium and magnesium, which cause limescale. In this way a pure and desalinated mineral water is obtained, capable of purifying the body, stimulating diuresis, expelling toxic substances and waste present in the body.
How does a reverse osmosis purifier work?
The water purification is guaranteed through 5 steps. Specifically, the 5 stages of the reverse osmosis purifier are as follows:
- First stage: the purifier by means of special sediment filters is able to discard very small corpuscles such as sand and rust
- Second stage: in this phase the purifier eliminates all organic impurities, chlorine, and pesticides through an activated carbon filter
- Third stage: this phase is very similar to the second, in which there is a further filtering of pollutants
- Fourth stage: the device filters viruses, germs, corpuscles, and other potentially dangerous elements through a 50 GPD reverse osmosis membrane at 0.0001 Micron
- Fifth stage: in this phase the purifier improves the taste of the water with an in-line activated carbon filter.
The under-sink and over-sink purifiers
The reverse osmosis devices from a structural point of view can be divided into two types: the under-sink purifiers and over-sink purifiers. Under-sink purifiers provide for the installation of the device in the compartment under the sink, making a hole in the sink to put a new tap next to the normal one. This solution is useful for small kitchens, as it is not bulky and allows you to save a lot of space.
The over-sink purifiers are on the other hand visible, so they are also more refined in terms of aesthetics and design to integrate perfectly with the kitchen. Due to their versatility, over-sink purifiers are used in kitchens, but also in offices, bars, and sports facilities.
Is reverse osmosis purified water good or bad?
There is a lot of discussion about the actual functionality of reverse osmosis purifiers, and for some time there has been an open battle between detractors and supporters of these devices. Where is the truth? Is reverse osmosis purified water good or bad? It does absolutely good and now let’s find out why.
Reverse osmosis purifiers produce low mineral content water, exactly like the light bottled water sponsored on TV. Furthermore, the water obtained is not demineralized, but only eliminates those elements that can be harmful to health. The level of mineral salts can also be adjusted using a special lever with which the purifier is equipped.
The result is a light water with a pleasant taste, capable of detoxifying the body and organs from all polluting and harmful substances. Also, to be considered is the great convenience of having a water purification system at home, which avoids going to the supermarket every day and carrying heavy packs of water that are not good for your back. Even foods prepared with the water obtained with the purifier, such as tea, coffee, pasta, etc. they will taste tastier and healthier.
Isn’t it also removing the minerals?
Minerals are inorganic nutrients that the organism cannot produce itself. These bulk and trace elements, which are mostly bound in salts, are filtered out. However, the human body meets its needs through food and not, as is often assumed, through drinking water.
So, there is no health risk from drinking osmosis water. Today we tend to take in too many salts. Classic table salt – sodium chloride (NaCl) – is usually consumed in abundance and, according to the relevant medical opinion, should generally be reduced. Here it helps if the water is low in minerals to support the kidney function and to remove excess salts.
The kidneys of newborns are usually not yet able to excrete the harmful substances and natural minerals (especially sodium!) From the body in sufficient quantities. For this reason, most waters are unsuitable for the preparation of baby food. It is also recommended to boil water suitable for the preparation of baby food beforehand. This serves to reduce germs and kill bacteria. Both are almost completely filtered out in osmosis water. So, osmosis water contributes to the healthy development of your child.
