Reverse Osmosis Define:-
Hello, you may be knowing that our body structured with 55% to 70% of water. Even our forefathers said that water is life, but we don’t count it in our primary needs. It is said that the third world war would be happening for drinking water. At present we are spending lots of money on the purification of water, but is the spending of money appropriate before going on the process of purification. In this article we are going to know about the most commonly used method for water purification is Reverse Osmosis.
Let’s get to know about the water in detail water covers 71% of Earth’s surface and on earth. 96.5% of the planets, water is found in oceans out of the remaining 3.5% percent. More than 2.5% percent of water is existing in the form of ice caps, clouds, vapors, biological bodies, and manufacturing products.
Less than 1% is available in the form of waterfalls, Lakes, reverse, wells, and bore wells for 700 corrode people animals, farms, trees, and factories, etc.
Now let’s turn on to the water purifying process let us consider RO technology, which is most popular and believed to be advanced technology of purifying industry.
Do you know? “how our technology works on purifying water?” let’s see in this process water and a high-pressure passthrough semi-permeable membrane having a pore diameter of 0.0001 micros.
In simple language, one curved portion of one millimeter that allows only water molecules to pass through it.
In such a minute filtration more than 90% of minerals, heavy metals, arsenic, and all the microorganisms get filtered this is similar to the natural purifying process.
How do reverse osmosis work:-
Reverse osmosis technologies at the heart and several of our drinking water systems too many the term may seem complicated or even intimidating.
First, let’s explain:
What osmosis is?
Osmosis is a naturally occurring process, in which a liquid such as water spontaneously passes through a membrane.
The membrane or semi-permeable barrier allows some molecules like water through, but other molecules like the majority of salts are unable to easily pass through the membrane.
Reverse Osmosis Process:-
The structure of the flow of liquids through such a membrane occurs naturally to try and even out the salt concentration between the two solutions.
That is a liquid flows from the less concentrated solution such as freshwater to a more concentrated solution such as seawater.
When the direction of liquid flow is reversed it’s called reverse osmosis by pressurizing the concentrated solution.
In this case seawater, we are able to force water molecules in the reverse direction from the salty sea water side through the membrane to the freshwater side.
The reverse osmosis membrane carries a charge and also the pores are very small whether your tiny water molecules pass-through there.
Reverse osmosis is how the water is able to pass through the membrane while leaving the other stuff behind.
The pressure outside pushes enabling the tiny water molecules to squeeze through the pores towards the low-pressure inside.
Purification of Water methods:-
The water from a lake or a pond may contain various impurities and germs of various diseases. The impurities from the water may be removed by decantation filtration, boiling and using chemicals.
Let us discuss these methods:
A] First Activity-
Take two glasses Aand B. A glass filled with tap water and glass B with water from a pond. Suspend a small piece of alum tied with the thread in each of the glasses. The border glasses undisturbed for some time.
After you will see that something has settled down in both the glasses. These are the impurities in the water. Now slowly tilt the glass and pour out the clear water in another glass. This process is called decantation.
B] Second Activity–
To take an earthenware pot with a hole at the base. Put some washed and cleaned gravel
inside the pot. Make layers of gravel about 7 centimeters thick in the pot, put some clean sand to about 7-centimeter thickness.
Place this pot on a clean vessel, put some water from a pond into the pot. Drops of water come out from the base of the pot. Through the hole observe the water that collects in the vessel.
It is clear but not safe for drinking. The water we get after decantation and filtration is not fit for drinking.
Even though it may look clean this water, is still contaminated with germs. That we cannot see the germs from this water can be removed by boiling boil the water. For 15 to 20 minutes cool the water and filter it.
Now we get safe water to drink we can also get safe drinking water by using chemicals. Let us see, how?
C] Chlorination Of Water:-
Take a glass filled with water dissolve a tablespoon of bleaching powder into it, add three tablespoons of this solution, into a bucket full of water and mix well.
Allow the water to stand undisturbed for about 30 minutes, bleaching powder kills the germs in the water and makes it safe for drinking.
This method is called chlorination of water the water supplied to our houses by the water department is
cleaned by this method.
Water Purifier with ro+uv+uf+tds:-
1] RO SYSTEM:-
If you think of RO based technology purifiers and the maintenance thereafter this would be two to three times of any other technology purifiers.
RO technology makes hard water sweet at the same time, if the water is sweet then it will demineralize and that will be harmful to human health.
when BMC water passes through the membrane due to chlorine in water the membrane sheet gets deteriorated after some time.
this weekend sheet gets choked due to scaling turbidity and enzymes created by bacteria this finally results in broken membrane sheet.
due to the excess pressure once it is broken impurities and bacteria can easily pass through it.
First of all, it is a filter, filters eventually deteriorate and need replacement with so many filters in an RO system, the maintenance expense can be quite costly.
Second RO systems can waste water some residential systems can waste water up to 10 gallons just to produce one gallon of purified water.
Bacteria can build up on the contaminated site of the semipermeable membrane, these colonies can then pass through the membrane.
RO systems are better than filters but not the most ideal solution to the final form of purification.
distillation mimics the hydrologic cycle. That nature uses to purify water the Sun heats up the water on the ocean.
2] UV SYSTEM:-
Now we’ll consider the old and most famous technology that is UV technology now what is you a technology bacteria grow with multiplication.
It means one bacteria gets divided into 2, 2 into 4 & 4 into 8 bacteria and so on in UV technology a high dose of ultraviolet energy at a wavelength of 254 nanometers.
It destroys pathogenic microbes by affecting the DNA in the cell and multiplication of microorganisms gets stopped and they cannot reproduce because of this within 20 to 25 minutes time when lifespan gets over they die completely.
Please consider the following middle of the UV chamber should be ideally food-grade stainless steel.
In spite of this. UV chambers manufactured by large companies are made out of aluminum the aluminum oxides which get discharged through this are harmful to the human brain.
UV chamber needs to be in a horizontal position rather than in a vertical position, in vertical position the moment of water is straight but in a horizontal position the water passes with a churning motion.
It ensures that all the germs get in touch with UV rays the intensity of any tube light available in the market.
This cannot destroy the DNA structure of microorganisms. The UV tube light cannot be immersed directly into the water, so to protect it from the water there is a provision of a quartz jacket.
But over a period of time, there is scaling and soil deposit formed on the quartz jacket and this causes obstruction to the UV rays.
Which in turn diminishes the resultant quality of UV system, UV rays are effective for many species of bacteria and viruses but not all. So we don’t require arrow technology and we can trust a technology 100%.
3] UF SYSTEM:-
In UF systems, the water passes through a hollow fiber membrane with point zero 1 micron pore size. Which does not allow bacteria, viruses, and turbidity? In the UF membrane with point zero 1 micron filtration.
We can easily remove microorganisms collides and minute turbidity from water without disturbing its natural mineral content.
This is similar to plant tissues absorbing purified water from the dirty subsoil water, therefore, UF technology is the best option for soft water, like the water supplied by BMC.
The advantages of UF technology are the ability to remove microorganisms and minute turbidity from water does not require electricity, low price, and less maintenance.
A few years ago some scientists from Bhabha Atomic Research Center developed a water purifier for Indians.
In which they use UF technology in September 2010. There was a survey conducted by one of the government bodies named, National Institute of virology on water purifiers in India.
In that test UV and RO, base purifiers fail but UF technology-based purifiers pass.
4] What Is Distillation Of Water?
For distillation process requires a heat source and when water boils, the steam will rise, or some of it will accumulate on the outside.
The condenser is equivalent to the cloud. When the steam passes through it, it gets cool down. So you can separate the liquid and the contaminants. This simple process called the distillation of water.
