How Does Water Purification System In India Work?

Clean and safe drinking water is a basic human need, but in many parts of India, this necessity remains a challenge due to pollution and contamination of water sources. Fortunately, water purification systems have emerged as a solution to this problem. 

In this blog, we'll explore how water purification systems in India work, shedding light on the processes and technologies that ensure the water you drink is safe and healthy.

What is the need for water purification in India?

In India, we need water purification because many of our water sources have various harmful substances in them which are bad for health. Hence, the water from most of the municipal sources, handpumps, etc. doesn’t have harmless and potable water. The harmful substances include germs, chemicals, and dirty things like sand and mud. So, water purification is now really necessary to clean our water and make it safe to drink.

It's really important because safe water keeps us healthy and free from water-related diseases. When we use water purification systems, we can be sure that the water we drink is good for our health. That's why learning about the working procedure of the water purification systems in India is really necessary!

Common Water Purification Technologies in India

Now, let’s have a look at what technologies are used in the water purification systems in India and what’s each technology associated with.

Chlorination

Chlorination is one of the oldest and most widely used methods for water disinfection in India. It involves adding chlorine or chlorine compounds to water to kill or inactivate disease-causing microorganisms. Numerous pathogens can be eliminated with this procedure.

Boiling

Boiling is a simple and cost-effective method to purify water at the household level. It kills most pathogens and makes water safe for consumption. It might not get rid of chemical pollutants, though.

Filtration

Filtration methods involve passing water through various porous materials to remove particles and microorganisms. Common filtration techniques include activated carbon filters and ceramic filters. These are frequently used together with other techniques.

Ultraviolet (UV) Purification

UV purification systems use ultraviolet light to destroy the DNA of microorganisms, rendering them harmless. This method is effective against bacteria, viruses, and parasites.

Reverse Osmosis (RO)

RO is a popular method for removing dissolved solids and impurities from water. It uses a semipermeable membrane to separate contaminants from the water. RO systems are commonly used to treat brackish or salty water.

Electrolysis

Some water purification systems in India use electrolysis to disinfect water. Electrolysis involves passing an electric current through the water, which generates chlorine and other disinfecting agents.

The Water Purification Process

The exact process of water purification can vary depending on the technology used. However, a typical water purification system in India involves the following steps:

Coagulation and Flocculation

This step involves adding chemicals like alum to the water to coagulate and clump together impurities and suspended particles. This makes it easier to remove them in the subsequent steps.

Sedimentation

The coagulated water is allowed to sit undisturbed, allowing the larger particles and floc to settle at the bottom.

Filtration

After sedimentation, the water passes through various filters to remove remaining particles and impurities. These filters can be made of sand, gravel, activated carbon, or specialized membranes, depending on the purification method.

Disinfection

To ensure the water is free from harmful microorganisms, it undergoes a disinfection process. This can involve chlorination, UV treatment, or other methods to kill or inactivate pathogens.

Post-Treatment

Some purification systems may include additional post-treatment steps to improve taste and odour, as well as to adjust pH levels.

Distribution

The purified water is then distributed through a network of pipes or stored in tanks for household use.

The Role of RO (Reverse Osmosis) Systems

One of the most popular and effective methods of water purification in India is the Reverse Osmosis (RO) system. These systems work on a simple yet powerful principle: forcing water through a semi-permeable membrane to remove impurities.

They use a special membrane to clean the water. First, there's a pre-filtration stage where bigger substances like sand are removed. The RO membrane has tiny holes that let water through but block harmful substances like chemicals and germs. After that, a carbon filter gets rid of any remaining weird tastes or smells.

UV (Ultraviolet) Purification for Added Safety

While RO systems are highly effective, some contaminants like bacteria and viruses can still pass through the RO membrane. To address this concern, many water purification systems in India incorporate UV purification as an additional step.

UV purification uses ultraviolet light to deactivate and destroy harmful microorganisms, ensuring that the water is microbiologically safe to drink. This extra layer of protection is particularly important in areas where waterborne diseases are prevalent.

TDS Controllers for Mineral Retention

One concern with RO systems is that they can remove essential minerals along with contaminants. To address this issue, many modern RO systems come equipped with TDS (Total Dissolved Solids) controllers.

TDS controllers allow some minerals to pass through while removing harmful impurities. This ensures that the purified water retains essential minerals like calcium and magnesium, which are crucial for your health.

Regular Maintenance is necessary

To ensure the continued effectiveness of your water purification system, regular maintenance is essential. Filters need to be replaced at recommended intervals, and the system should be inspected for any leaks or malfunctions. Proper maintenance ensures that your RO system continues to provide you with clean and safe drinking water.

Conclusion

Water purification systems in India play a pivotal role in purifying water, especially in areas with high TDS and brackish water. Their ability to efficiently remove a wide array of impurities has made them indispensable in both household and industrial applications.
