Seven Stages of Water Treatment

What are the 7 Stages of Water Treatment?

The human body comprises 60% water, necessitating humans to drink ample water every day. Drinking impure water can introduce life-threatening diseases to your family. Therefore, ensuring your drinking water is pure and free of contaminants is vital. Water treatment systems in your house can help purify your drinking water through a well-designed purification process. 

Here we give you a complete breakdown of the water purification process. 

Ion exchange and coagulation

The first step of water purification is eliminating unwanted minerals from the water supply. The water supply is hygienic, but sometimes contamination occurs, and deposits like iron and calcium get dissolved in water. Through the process of ion exchange, heavy metals and other residues are separated from the water through. After that, alum is added to settle down sediments in the water. 


The next step is sedimentation, in which any floc, dirt, dust particles, and other contamination that is insoluble gets settled at the bottom of the container. Most water treatment systems in Florida have sedimentation filters to handle the sedimentation process. 

Filtration and granular activated carbon

The third step is filtration, in which water is passed through layers of sand or charcoal to remove any leftover particles of dirt or impurities. After that, it is passed through activated carbon to remove any dissolved chemicals like chlorine and herbicides. 


After the soluble and insoluble impurities are removed from the water, the next step is to remove any harmful microorganisms in the water. It is done through disinfection. Most commonly, ultraviolet rays kill the bacteria and viruses in the water. The water treatment systems have a closed tank that is used to pass the rays through the water. 

Carbon filters

Post disinfection, the tank’s water is again passed through carbon filters to remove any remaining particles or dust from the water before sending it for reverse osmosis. 

Reverse osmosis

The next step of the purification process involves passing the water through a thin semi-permeable membrane to remove any dissolved contaminants in the water. The water molecules easily pass through the membrane, leaving behind other dissolved materials. This process is known as reverse osmosis.

Reverse osmosis is the most common filtration method used in water purification systems.   

Storage of purified water

The final step of water purification is to store the purified water in a container or tank from where you can collect it to drink whenever you want. 

Treating the water before its consumption is essential to protect yourself and your family from water-borne diseases. Call professional water filtration system installers in Florida like Henry Plumbing to help you set up a water treatment system in your house.
