Assessing the influence of water purification on microbial communities in drinking water

Microbial contamination in drinking water refers to microorganisms such as bacteria, viruses, parasites, and fungi in water intended for human consumption. These microorganisms can harm human health and cause typhoid fever, cholera, dysentery, and diarrhoea. Here, the following article will discuss the purpose of water purification along with microbial contamination in drinking water. 

Sources of microbial contamination in drinking water

Can originate from various sources, including:

Animal and human waste - This is the most common source of microbial contamination in water. Sewage systems, septic tanks, and animal waste can all contaminate water supplies.

Agricultural activities - Fertilisers, pesticides, and animal manure used in farming can contaminate water supplies.

Industrial activities - Waste from industrial activities can contaminate water supplies with harmful chemicals and microorganisms.

Natural sources - Natural disasters such as floods and hurricanes can contaminate water sources with microorganisms.

Effects of Microbial Contamination

Microbial contamination in drinking water can have severe health consequences, especially for vulnerable populations such as children, pregnant women, people with weaker immune systems and the elderly. Some effects of microbial contamination include

Gastrointestinal illnesses - Microorganisms such as bacteria, viruses, and parasites can cause gastrointestinal diseases, leading to vomiting, diarrhoea, and dehydration.

Hepatitis A - The hepatitis A virus can be transmitted through contaminated water and cause liver disease.

Cholera - Cholera is caused by the bacterium Vibrio cholera, which can be transmitted through contaminated water. It can cause severe diarrhoea and dehydration and can be fatal if left untreated.

Typhoid fever - Typhoid fever is caused by Salmonella typhi and is transmitted through contaminated water. It can cause high fever, headache, and abdominal pain.

How to prevent microbial contamination?

Now coming to the purpose of water purification; preventing microbial contamination and TDS in drinking water requires a combination of measures, including:

Proper sewage treatment - Proper treatment of sewage and waste is crucial to preventing microbial contamination of water sources.

Protection of water sources - Protecting water sources from contamination through proper land use and agricultural practices can prevent microbial contamination.

Water treatment - Treating water with chemicals such as chlorine or through filtration can remove microorganisms and make the water safe for human consumption.

Regular testing - Regular testing of water sources and treatment facilities can help detect and prevent microbial contamination.

The Importance of water filtration systems in ensuring safe drinking water

Water is one of the essential components for human survival. It is necessary for various bodily functions, including digestion, metabolism, and temperature regulation. Nevertheless, not all water sources are safe to drink. Various pollutants, such as chemicals, bacteria, viruses, and other harmful substances, can contaminate water. Therefore, the purpose of water purification systems in place to ensure that the water we drink is safe and clean.

Water filters are designed to remove water contaminants and improve quality. They use different methods to filter water, such as sedimentation, biological filtration, adsorption, and disinfection. Each method effectively removes different contaminants, depending on the water source and the filtration system.

One of the main benefits of water filtration systems is that they can remove harmful bacteria and viruses from the water. These microorganisms can cause severe illnesses like cholera, typhoid fever, and dysentery. By removing them, water filtration systems can significantly reduce the risk of waterborne diseases.

The purpose of water purification systems can also remove chemicals and other pollutants from the water. These pollutants can come from various sources, such as industrial waste, agricultural runoff, and sewage. They can have serious health effects on humans, such as cancer, neurological damage, and reproductive problems. By removing these pollutants, water filtration systems can improve the overall quality of the water and reduce the risk of long-term health problems.

In addition to health benefits, the purpose of water purification also serves environmental benefits. By removing pollutants from the water, they can reduce the impact of human activities on the environment. For example, Agricultural runoff can dirty water bodies and cause problems like too many algae and dead fish. Water filtration systems can prevent these harmful effects by moving the excess nutrients from the water.


Another benefit of water filtration systems is that they can improve the taste and smell of the water. Many people prefer to drink water free from unpleasant tastes and odours. Water filtration systems can remove the minerals and other substances that cause these tastes and odours, making the water more palatable.


The most common types include activated carbon filters, reverse osmosis, and ultraviolet disinfection systems. Each method has advantages and disadvantages, depending on the water source and the user's needs.


Activated carbon filters are effective in removing organic compounds, such as pesticides, herbicides, and industrial chemicals. They are also effective in removing chlorine and other disinfectants used to treat water. However, they may not effectively remove certain types of bacteria and viruses.


Reverse osmosis systems use a semi-permeable membrane to remove dissolved solids, such as minerals and salts, from the water. They effectively remove a wide range of contaminants, including bacteria, viruses, and chemicals. 


UV disinfection systems employ ultraviolet light to eliminate germs and viruses in water. They are effective in removing microorganisms, but they do not remove other types of contaminants, such as chemicals and minerals.


Regardless of the kind of water filtration system used, it is essential to maintain it properly to ensure its efficacy. This includes regular cleaning, replacing filters, and monitoring water quality. In addition, it is crucial to test the water periodically to ensure it is safe for consumption.
