Understanding Water Purification Chemicals

Water purification chemicals are substances used to treat impurities and contaminants in water, ensuring it is safe and suitable for various applications. These chemicals play a vital role in maintaining water quality and preventing the spread of waterborne diseases. They are commonly used in public water treatment facilities, industries, household water filters, wastewater treatment plants, disaster relief and emergencies.

Different Types of Water Purification Chemicals


Chlorine is one of the most commonly used water purification chemicals. It works as a disinfectant by killing bacteria, viruses, and other harmful microorganisms in water. Depending on the application and desired concentration levels, chlorine can be added as a gas, liquid, or solid. It is widely used in public water treatment facilities and household water filters.


Fluorides are chemicals added to water to prevent tooth decay. They help in strengthening teeth and reducing the risk of dental caries. Fluorides are generally added in controlled amounts to public water supplies and are considered safe when used within recommended limits.


Chloramines are formed by combining chlorine and ammonia. They are used as an alternative to chlorine in water disinfection. Chloramines have a longer residual disinfection effect and are less likely to produce harmful byproducts than chlorine. They are commonly used in public water treatment systems.


Bromine is another effective water purification chemical used for disinfection. It is commonly used in spas, hot tubs, and swimming pools. Bromine works by killing bacteria and other microorganisms present in water. It is considered to be a more stable disinfectant compared to chlorine, especially in higher-temperature environments.


Iodine is a water purification chemical commonly used in emergencies and outdoor activities where access to clean water is limited. It is effective against many microorganisms, including bacteria, viruses, and protozoa. Iodine is available in tablets, drops, or crystals, making it a convenient choice for portable water treatment.

Applications of Water Purification Chemicals

Use in public water treatment facilities

Water purification chemicals are extensively used in public water treatment facilities to ensure the safety and quality of drinking water. These chemicals are added during treatment to disinfect the water and remove impurities. Chlorine and chloramines are commonly used in these facilities because they kill harmful microorganisms.

Application in industries

Various industries such as food and beverage, pharmaceuticals, and power generation rely on water purification chemicals for manufacturing. These chemicals help remove contaminants and maintain the required water quality standards. Industries often use specialized water treatment chemicals tailored to their specific needs, such as scale inhibitors, corrosion inhibitors, and coagulants.

Usage in household water filters

Water purification chemicals are crucial in household water filters, ensuring the water is safe and clean for consumption. Chlorine and activated carbon are commonly used in these filters to remove impurities, including bacteria, sediment, and odour. These chemicals improve the taste and odour of water, making it more desirable for everyday use.

Role in wastewater treatment plants

Wastewater treatment plants utilize water purification chemicals to treat and purify wastewater before it is discharged into the Environment. These chemicals aid in removing contaminants and pollutants, ensuring that the water is not harmful to the ecosystem. Coagulants, flocculants, and disinfectants are commonly used in wastewater treatment processes.

Use in disaster relief and emergency water treatment

Water purification chemicals are essential in disaster relief efforts and emergencies where clean water is scarce. These chemicals enable the rapid treatment and disinfection of contaminated water, ensuring its safe consumption. Portable water treatment solutions, such as iodine tablets or chlorine-based disinfectants, are often used in these cases.

How Do Water Purification Chemicals Work?

The process of water disinfection

Water disinfection involves using chemicals to kill or inactivate microorganisms in water. Water purification chemicals, such as chlorine, chloramines, and iodine, work by damaging the cell membranes and genetic material of bacteria, viruses, and protozoa, rendering them harmless. This process prevents the spread of waterborne diseases and ensures water safety.

Methods of water treatment using chemicals

Water treatment using chemicals can be done through different methods, depending on the specific needs and available resources. Common methods include batch treatment, continuous treatment, and point-of-use treatment. Batch treatment involves adding chemicals to a specific quantity of water and allowing it to react for a designated period. Continuous treatment involves continuously adding chemicals to maintain a desired residual concentration. Point-of-use treatment refers to adding chemicals directly to the water at the point of consumption, such as using water purification tablets.

Interaction of chemicals with contaminants

Water purification chemicals interact with contaminants in water through various mechanisms. For example, chlorine reacts with organic matter, bacteria, and viruses to form disinfection byproducts and oxidize organic compounds. Coagulants and flocculants help remove suspended particles by creating larger particles that can be easily filtered or settled out. These interactions are crucial for effectively removing contaminants and ensuring water quality.
