Clean and safe drinking water is important for all of us for living a healthy life, but have you ever wondered why some water tastes bad even after it has been treated? Many people are not aware of the factor that affects water quality which is TOC (Total Organic Carbon). You may not see it with your eyes but it plays a major role in the taste, smell, and safety of your drinking water.
In this blog, we will explain what TOC in water means, why it is important, what causes high TOC, and how TOC water treatment works in Indian homes and cities.
What is TOC in water?
TOC basically tells you how much natural material is mixed in the water. It is measured in ppm which just means how many parts of this material are present in a million parts of water. This organic matter includes things like tiny plants, animals, or other natural stuff that comes from living things.
When these organic things break down, they leave behind carbon. A small amount of organic matter in water is normal, but when the TOC level gets too high, it can start to affect the water’s taste, smell, and overall quality.
Why does TOC matter for drinking water safety in India?
- Changes the taste and smell of water: When TOC levels goes up, the water may start to smell earthy, taste strange, or look slightly colored. This often happens during the rainy season or in areas where old pipelines are used.
- Can create harmful by-products: Chlorine is commonly used to clean water in India. But when chlorine mixes with water that has high TOC, it can form certain by-products. Drinking water with these by-products for a long time may not be safe.
- Makes purification less effective: High TOC means the water contains a lot of organic matter, such as decayed plants, algae, sewage particles, and other substances. Because of this, purification systems, whether at home or in large treatment plants, have to work much harder. It can clog filters quickly, block RO membranes, and increase the need for chemicals in large water plants.
- Shows signs of contamination: If TOC suddenly increases, it usually means something has mixed with the water that should not be there, such as sewage, chemical waste, or decaying plant matter.
Because of these risks, checking TOC levels regularly is important for both homes and industries to make sure the water stays safe to drink and use.
Top reasons for high TOC in Indian water
In Indian cities and towns, high TOC water comes from a variety of sources. Here are some of the most common ones:
Natural organic matter from the environment
In India, with its monsoon season, natural organic matter from the environment washes into rivers and lakes during rains which is the most common source of TOC.
Industrial Wastewater
Factories and industries sometimes release untreated or poorly treated wastewater into lakes and rivers. In cities like Mumbai and Delhi, industries discharge organic pollutants from manufacturing processes, including oils, dyes, and other materials that raise TOC levels.
Agricultural Runoff
Farms use fertilizers, pesticides, and crop waste. During rainfall, these wash into canals and groundwater, increasing high TOC levels.
Sewage leakage and poor drainage
Old or poorly maintained pipelines and storage tanks with drinking water lines can be the reason to raise TOC.
Simple TOC water treatment methods in India
Different methods are used depending on whether the water is for home use, industrial processing, or municipal supply. Here are the most effective water treatment options in India:
Activated Carbon Filtration
Activated carbon is a special form of carbon with lots of tiny holes widely used in homes and industries. When water passes through an activated carbon filter, they absorb organic matter and removes odors, and improves taste.
RO (Reverse Osmosis) Systems
RO systems are used especially in homes and offices. They push water through a membrane that blocks larger particles and many organic substances.
Advanced oxidation processes
AOP uses things like ozone (a gas) or ultraviolet (UV) light to break down organic matter into harmless bits. This method is common in municipal companies and industries.
Conclusion
TOC in water is an important indicator of water quality. In a country like India, where water issues are common, keeping an eye on TOC can prevent problems like strange taste, bad smell, or even health concerns. When you know your TOC levels and treat the water properly, you can protect your home, your family, or your business.
