A Brief Description About Reverse Osmosis Water Purifier

A water purification system is one of the crucial equipment for every house hold. Because a water purification system eliminates each types of waterborne disease causing pathogens and agents this provide you to live a healthy life. There are large number of water purification system but an RO water purifier is one of the most trusted and widely used water purification system. The RO water purifier is use to eliminates all kind of water contaminations or in other words it is use to bring 100% pure and healthy water for the drinking purposes.

Pure Osmosis Vs. Reverse Osmosis

Osmosis is defined as the flow of fluid (liquid) molecules from the low concentration of solutes to the high concentration of solutes. It don’t require energy thus regarded as automated whereas the reverse osmosis process is completely opposite to the osmosis. The reverse osmosis (RO) is the most widely use technique in the field of the water purification system. This technique is entirely opposite to the pure osmosis process. In reverse osmosis process water or solvent is allowed to pass through a semi-permeable membrane under the influence of external pressure.

The process of osmosis mainly occurs to maintain the equilibrium, i.e., osmotic balance. It also balances the concentration of the solute and fluids across the semi-permeable membrane. The osmosis process is crucial in the biological process whereas reverse osmosis shows its great importance in the various water purification process.

A water purification process is mainly used to treat contaminated water to bring out the pure and healthy water for the drinking purposes. There are several technology which has shown its significance in the water purification process, but reverse osmosis is the best & widely accepted among all water purification system to treat impure water since the 1950s.

What are the importance of Reverse Osmosis Water Purifier?

As we know that water is a natural solvent which can dissolve everything in it hence it is also regarded as a universal solvent. This property of water makes it natural habitat of several molecules and the presence of high concentration of any substance in water makes it unfit for drinking purposes. In India, the drinking water quality is inferior thus it requires a significant way to eliminate contaminant or pollutant present in water. According to the UN report, India's rank is 120th among the 122 countries in term of drinking water quality.

Water may contain various types of water pollutant like dissolved solids, unwanted or high or low concentration of minerals, micro-organism, pharmaceutical or medical waste, Radioactive waste, &, etc which needs to be removed from the drinking water because it can leads to various types of waterborne diseases. It is proven that most of the waterborne diseases are fatal if not treated appropriately. According to the report of WHO (World Health Organization) waterborne diseases kills more than 3 million lives every year globally in which the number of children is very high as compare to the adult. The consumption of contaminated water mostly affect those people whose immune system are not properly developed. The immune system of the children are not properly developed or in the developing stage, so the waterborne diseases affect the child more than the adult person. Cholera, Typhoids, Diarrhoea, Dysentery &, etc are some of the most common waterborne disease in India.

Working Of Reverse osmosis Water Purifier system

In reverse osmosis water purification system, the input water pass through mainly three stages and these stages are

  • • Pre-filtration

It is the first step of the reverse osmosis process. The pre-filtration is mostly used to protect the reverse osmosis membrane i.e., RO membrane. Its work is to punch out the dissolved salts/solids and to lower the concentration of the chlorine from the water. The pre-filtration stage of RO water purification system is known as sedimentation, and sedimentation is based on the filter which is called a sediment filter or spun. The sediment filter is nothing but a sieve with certain pore size. The pore size of the pre-filtration or sediment filter is in micron, and the substance whose pours size is more than the pore size of the pre-filtration can’t pass through it.

  • • Reverse osmosis Process

During the reverse osmosis process the input water is forced to pass through the RO membrane which is selectively permeable under the applied external force or pressure. This membrane is also known as RO membrane and it is made up of synthetic material and only allows the water molecules to pass through it but don’t allow the passage of the larger molecules such as bacteria, fungi, algae, and viruses. An RO membrane contains several pore and its size is about the 0.0001 which does not allow the large molecules to pass through it. The reverse osmosis (RO) water purifier is certified for the reduction of lead, arsenic, copper, nitrates, nitrites, etc concentration from the water.

  • • Post-filtration process

It is also known as a second carbon filter which remove all those impurities which remain in the water even after the sedimentation & reverse osmosis process. The post-filtration process offer the final polishing to the water. This stage also improves or enhance the taste of the water.

Some Benefits of Reverse osmosis water purification System

An RO water purifier offers multiple advantages over other forms of water purifier. Some of its advantages are given below

  • • Reduce the Level Of Lead

Presence of high concentration of lead in your body may causes several health condition such as brain damage, infertility, the problem in nerves system and muscle development. As per the report of the center for the Disease and Prevention, the reverse osmosis (RO) water purification system can eliminate the excess amount of the lead from the water and making it safe & healthy for drinking purposes.

  • • Eliminate Cryptosporidium

The cryptosporidium is a parasite which mostly found in the water, but the reverse osmosis water purifier system protect you from this parasite because an RO membrane does not allow it to pass through the membrane. This parasite mainly affects the small intestine and can cause stomach cramp, fever & Diarrhea in the infected person.

  • • Enhance taste

The reverse osmosis water purification system eliminated all contamination or pollutant from the water. An RO water filter system removes approximately 90-95% of dissolved contamination and improves the taste of the drinking water. However the water is a tasteless & odorless substance, but impurities may add some unpleasant flavor and odor in the water. Hence removal of contamination is necessary to improve the taste of the water.
