7 Key Process Steps Involved in a Water Purification Facility

August 19, 2025 | by admin

Access to clean drinking water is a basic human requirement. Hence, it’s necessary to ensure the safety of the water we are consuming every day. In making water free of pollutants, water purification plants play a pivotal role. These facilities utilise a series of well-organised steps to treat raw water from natural resources.

We all know that the primary purpose of these plants is to make water safe for public consumption. So let’s dive deeper and explore the seven key process steps involved in a water treatment plant. Contact a renowned water treatment plant provider in West Bengal to get industrial-grade water treatment plants.

The Basics of Water Treatment Plants

A WTP or water treatment plant is a facility used to treat raw water. These plants purify the water sourced from lakes, rivers, or underground reservoirs. Water treatment plants aim to convert raw water into potable water. The objective is to eradicate chemical, physical, and biological pollutants through a series of treatment procedures. Hence, water treatment plants also ensure compliance with safety and health standards.

Significant Process Steps Involved in a Water Purification Plant

So, as of now, you may realise what water treatment plants are. Now it’s time to discuss the key process steps involved in a water purification plant.

• Intake & Screening

The first significant procedure involved in a water treatment plant is intake and screening. This process starts with the collection of raw water from the source. You can remove large debris, such as branches or leaves, and other waste materials with this step.

• Coagulation & Flocculation

The second step of the effective water treatment procedure is coagulation and flocculation. Coagulation is known for adding chemicals known as coagulants. Many of us are not aware that the primary purpose of coagulation is to destabilise suspended components.

On the other hand, flocculation is a gentle mixing procedure. It facilitates those components to develop bigger flocs or clumps, which you can remove easily. To receive high-end water treatment plants for safe and clean water, contact a leading water treatment plant provider now.

• Sedimentation

The third step of a water treatment plant is sedimentation. In this step, a large sedimentation basin is necessary to make the water sit in. In the basin, the heavy flocs settle to the bottom due to gravity. This step is essential to remove most of the suspended solids.

• Filtration

The next significant step of the water purification process is filtration. In this step, the purified water passes through filters made up of gravel, sand, and sometimes activated carbon. This step eradicates smaller components that haven’t settled during sedimentation.

• Disinfection

The fifth step of an effective water treatment process is disinfection. This step is vital for adding disinfectants such as chloramine or chlorine. Disinfection ensures that the drinking water remains safe even during distribution.

• pH Settlement & Additional Treatment

pH settlement and additional treatment are the next prominent steps of water purification. This step involves the use of certain chemicals to adjust the pH and enhance taste. It’s also important for preventing corrosion in distribution pipes. In some cases, fluoride can hold great importance for dental health benefits.

• Storage & Distribution

The last and final step of an effective water treatment process is storage and distribution. This step involves storing the treated water in covered tanks or reservoirs. This last step also highlights the even distribution of water through a network of pipes to reach businesses, households, and public facilities.

Conclusion

The procedure followed in a water purification plant ensures the safe and clean water. From the basic screening to final disinfection and storage, each step is essential. All of them are crucial for altering raw water into drinking water that is compliant with health standards.
