7 Methods Of Water Purification Process

The RO Services in Gurgaon or access to pure and healthy water for drinking purposes can protect millions of lives every year. This can be achieved by the following methods which are given below-

1. Boiling

Boiling water is one of the cheapest and best ways to purify water. Water is one of the natural solvents which can dissolve almost everything. This property of water makes its natural habitats for various kinds of pathogens which can’t be seen by the naked eye. The boiling of water removes these kinds of pathogenic germs and bacteria.

2. Coagulation & flocculation

This is the first step of the water purification in which some chemicals are added into the water for the removal of the suspended particle from the water. These added particles can be organic such as bacteria, viruses, fungi, algae and any other natural organic compound and inorganic in nature such as clay and silt.

The addition of inorganic coagulants such as aluminum sulfate or iron salt such as iron chloride induces several chemical and physical interactions among the particles. The negative charge on the particles gets neutralized by the inorganic coagulants and starts forming a metal hydroxide of aluminum ions and iron.

These metal hydroxide i.e. Aluminum and iron hydroxide precipitate combine together and form a large compound under a natural process called Brownian motion or under induced mixing called flocculation. These metal hydroxides start absorbing the suspended particle in the water and induce removal of those suspended particles by a subsequent process of sedimentation & filtration.

Organic coagulants are a man-made organic polymer. This polymer contains the high molecular size and when it added into the water it starts absorbing the suspended particle present in the water and forms flock.  

3. Sedimentation

Sedimentation is a physical process that removes suspended particles from the water using gravity. The particle which settles out from the water is called sediment or sludge. The thick layer of sediment is known as consolidation.

Water containing flocculation basin enters into the sedimentation basin, The sedimentation basin is a large tank that has low water velocities which allow the suspended particle to settle at the bottom. The flocculation basin and sedimentation basin are closed to each other that is why this process does not allow the floc to break up.

Before the coagulation process in the water treatment process, sedimentation could be used to decrease the suspended particle present in the water. But after the coagulation process sedimentation is used to reduce the solid particle from the water so that the filtration process can function effectively.

4. Filtration

Any mechanical, physical or biological operation which is used to separate solids from the fluids (i.e. Liquid or gas) by adding a medium which only allows the fluids to pass through it but doesn't allow the solids to pass. The fluids which pass through it is called the filtrate. There are various methods of filtration such as hot filter, cold filter, and vacuum filter and all these filters aim to separate the substance.

Filtration is one of the active water purification processes among all the methods used for purification. It is mainly based on physical and chemical processes. Filtration ensures that your drinking water is safe for consumption purposes because it removes all kinds of water contamination from the water.

When you compare the water filtration process with reverse osmosis (RO) that filtration is most effective as it removes much smaller molecules like chlorine and pesticides. Distillation is not only effective but also economical as it doesn’t require more energy as compared to reverse osmosis. During the filtration process, little loss of water takes place.

5. Disinfection

The process of cleaning something to destroy microbes is regarded as disinfection. It could be done by removing harmful micro-organisms or by adding disinfectant chemicals. Disinfection can be achieved by chlorine, chlorine dioxide, chloramine, ozone, and ultra-violate (UV) rays.

Chlorine and its compounds such as chlorine dioxide and chloramine is a strong oxidant which efficiently kills the micro-organism whereas ozone is unstable molecules which produce natation oxygen which acts as a powerful oxidizing agent. Ultra-violate rays are very effective at reducing contamination.

6. Distillation

The process of separation of any substance from a liquid mixture through selective boiling and condensation. It could be done to achieve complete or partial separation which results in a higher concentration of the selective compound.

Distillation is one of the water purification methods which utilize heat to collect pure water in the form of vapor. According to the scientific fact, distillation is one of the best water purification methods because the boiling point of water is less as compared to the other water pollutant and disease-causing agent.

In the distillation process to achieve water purification, water is subjected to heat until it reaches its boiling point. After that, water is allowed to vaporize and directed into the condenser to cool. After cooling vapors reverse into water that is clean and pure. Another substance that has a higher boiling point remains in the container.

This method of water purification has its advantage and disadvantages. The advantage of distillation is that it affects water purification methods in terms of eliminating bacteria, germs, salts, and other heavy metals like leads, Arsenic. The notable disadvantage of distillation is that it is a slow process and requires a heat source for the water purification process. This process has one significant disadvantage that it is only effective for the smaller quantity not for the large scale.

7. Chlorination

Chlorine is one of the powerful water purification methods which kills germs, parasites, and other disease-causing agents present in your regularly used water. Chlorine is one of the cost-effective water purification methods among all the know water purification methods. It is mostly used in municipal water to deliver pure and safe water for home consumption.

Additional methods for water purification Process

1. Granulated activated carbon

It is a form of activated carbon which has more surface area, more surface area allow it to absorb many toxic compounds. 

2. Reverse osmosis

In this technology, water is allowed to pass through a semi-permeable membrane under mechanical pressure. Researches say that reverse osmosis (RO) is the widely used technology for water purification. The application of RO technology is to find reverse osmosis service near me.

3. Gas hydrated crystals centrifuged methods

This method uses low molecular weight gas or carbon dioxide which is mixed with the contaminated water at low temperatures and high pressure.

4. In-situ chemical oxidation

It is an advanced form of oxidation which is achieved by inducing the effective oxidizer agent into the contamination medium to destroy the impurities.

5. Bioremediation

This technology use micro-organism to remove waste products such as alkenes & perchlorates from the contaminated water.

The water purification process is used to reduce the contamination present in the water. As we know water is a universal solvent and it can dissolve almost everything in it. Due to this property of water, it becomes the natural habitats for several disease-causing pathogens or agents. These pathogens can be hazardous in nature thus before drinking water you should purify it. The water purification process is used to eliminates all kinds of contamination present in water. Different types of water purification processes are used to eliminates different kinds of contamination present in water. 

Water Purification System And Its Various Type

A device that is used to purify water is called a ro servicing near me. Various kinds of water purification systems are available in the market, such as water purifiers, water softener, and others. Previously boiling of water was the most trustable water purification method. But, as these days, the water impurities are getting rigid, an advanced water purification system replaces boiling of water.

With the regular enhancement in the technology, the water purification system is getting updated, which ensures you purest drinking water all the time you urge to drink water. Now it is available in various sizes and capacities, which makes it suitable for multiple sectors like domestic, commercial, and industrial.

Types of Water Purification System

Here we have listed two different types of water purification system which are

1. Water purifier

A water purifier is one the best and trusted water purification system which eliminates all kinds of impurities present in raw water. As we all know, water is one of the universal solvents due to which water becomes home of several contaminants such as microbes and heavy metals. A water purifier is based on various kinds of advanced technology like reverse osmosis (RO), Ultra-Violate rays (UV-rays), and Ultra-Filtration (UF) and many others.

Types Of Water Purifier

There are various kinds of water purification systems in the Indian market. All of them are designed in such a way that it can eliminate all types of contamination present in water. Here we have listed some of the top and widely used water purification techniques such as

  • Reverse Osmosis (RO)

It is also known as RO. Reverse osmosis is the opposite of pure osmosis. In this technology, water is used to pass through a semi-permeable membrane. The semi-permeable membrane has several tiny pores that eliminate water contamination based on the molecular size of the contamination. Although the RO water purifier removes all kinds of contamination present in water, it is suitable for removing the high TDS concentration present in water.

  • Ultra-Violate Rays (UV)

Several water purifier manufacturer uses UV rays. The UV rays present in the water purification system ensure that no microbial contamination will remain in the water. The UV rays kill to suspend the growth of the microbes present in water. But UV rays don’t eliminate other kinds of contamination present in water like a suspended particle.

  • Ultra-Filtration (UF)

Ultrafiltration is one of the water purification methods which uses membrane. But this technology only comes in a combination of RO and UV water purification technology. The UF water purifier is mainly used to protect the RO and UV membrane by removing larger molecules present in water.

2. Water Softener

It is a type of ro service center which is used to treat hard water. The high concentration of Calcium and Magnesium makes water hard in nature, which is not suitable for your health, especially skin health. A water softener replaces the Calcium and Magnesium ion by Sodium ion and makes water soft.
