Water Purification Process Explained

Water Purification Process Explained

Did you know that studies have found more than 300 contaminants in drinking water around the country? 

Without proper filtration, water can be dangerous and even fatal if bacteria get in your cup. 

If you want to learn more about the stages of water purification, there are only a few steps to discover. 

Continue reading to learn about each step of the water purification process so that you understand what you are drinking! 

Chemical Coagulation

The first step in the water purification process is chemical coagulation.

This step involves adding chlorine dioxide to the water to reduce organic matters that are harmful to consume. This stage also gets rid of decaying plants and leaves that find their way into the water. 

Aluminum sulfate is also added during this phase to help disperse debris from clean water. This makes it easier to skim off the top. 


Next in the drinking water purification process is flocculation.

Flocculation involves a machine that water gets added into. The machine mixes and stirs the water, promoting contact between sediment particles. Since sediment is difficult to remove from water, this phase is essential. 

The flow and speed of the mixing help separate the sediment and created a more purified batch of water. 


Attached to the flocculation machines you can find one for sedimentation.

The sedimentation process eliminates heavier particles and solids still in the water. Filters catch these particles with the help of gravity. This is one of the most effective forms of removing solids in water and shouldn’t get skipped. 

Minerals are great for the body, but only to a certain extent. Sedimentation brings these minerals levels to a healthy level for you to drink. 


After all of the particles have been removed from the previous steps of water purification, they must be disinfected.

Disinfection utilizes chlorine to kill any microorganisms or bacteria remaining in the water. No matter how much filtration your water receives, it won’t be pure until it’s free of the “un-seeable” contaminants. 

This phase reduces the bacteria and viruses transferring through the water. When water doesn’t get disinfected, cases of cholera, dysentery, and typhoid increase. 


Coal, sand, and other organic elements are used to further filter water. 

These granular substances help filter water as they filter their way down. These elements act as a natural “strainer” for water and reduce the remaining contaminants. By searching commercial water filtration near me you can discover your options. 

Filtering water can provide a refreshing and pure taste. Charcoal is another ingredient that reduces contaminants and produces purer water. 

The Water Purification Process Flows Smoother Than You Think

Learning the water purification process can help you identify safe and unsafe water to drink.

Knowing what phases the water has been through will determine what contaminants you could get exposed to. For example, disinfection gets rid of bacteria while coagulants pull out larger sediment. Each step in the process is just as essential as the next. 

Pay attention to the status and condition of water in your area to determine what contaminants you will get exposed to.
