Seven Steps of Water Purification


Water is very important for everyone on Earth. A human body is made up of approximately 60% water. We also lose an enormous amount of water every day. Hence, it becomes essential for us to drink enough liquid to maintain the water levels in the body. Clean and pure water adds a lot of benefits. That’s the reason water purification is very important.


This is the first step of water purification process. Water from municipal systems is contaminated with unwanted minerals. This step helps to remove such minerals which form hard water, pipe scaling, and deposits. Some of the heavy metals such as iron, cadmium etc. are also separated through this procedure.

The next step is to add alum and other chemicals to the water due to which flocs or small viscous pieces are formed. Dirt particles are attracted by these flocs which ultimately turn them heavy. Now they can go down easily and settle at the bottom of the water settling tank.


In the next step to water treatment services, floc and the water go in for the sedimentation process. As the water settles in the basin, flocs descend at the bottom and reside there. Further, they can be removed.

The sedimentation process also includes the sediment filters which trap particles such as dirt, sand, etc. This protects equipment from getting polluted and blocked. Hence, sediment filters are required at an early stage to avert damage to the equipment which would be used in the later phase.


Now, water is filtered and passed through layers of sand, charcoal, etc. In this process, particles which were left after the previous step are removed.

There is a carbon filtration process as well which significantly removes herbicides, chlorine, suspended particles, and other pollutants such as volatile organic compounds.


In the next step, water is moved into a closed tank with ultraviolet lights. It works as a strong sterilizing agent. If we talk about only groundwater, this process is sufficient to treat the water. It can kill all the microorganisms in the water. After the disinfection process, water flows into the homes through pipes where it is again processed using reverse osmosis or RO filters.


This filter is designed to capture impure particles present in the water. A carbon filter before reverse osmosis also protects the RO machine as it removes contaminants from the water and almost clean water goes into the system.


Once water reaches homes, it has to pass through another purification process known as reverse osmosis (RO). In this process, a semi-permeable membrane is used to remove impure particles present in the water, if any. The RO system removes the dissolved particles as well which would have been missed in the previous step. It also adds a sweet taste to the water.


Clean water is then stored in the water tank. These tanks are made by FDA approved materials. Water purifier systems also use stainless steel on all water contact areas.
