What are the 7 steps for water treatment?

Pure water is important to maintain a healthy life. Drinking contaminated water can create many health complications and make you suffer. That is why we must make it a habit to always drink pure water. Water purification is a much-needed procedure to make sure that everyone gets access to safe drinking water.

Water can be treated in several steps to make sure that no contaminant is present in it. Water treatment on a wide scale lowers the risk of water-borne diseases and can prevent many deaths that are caused by these diseases. Municipalities should take water treatment seriously to ensure safe drinking water for everyone.

Why is Water Treatment Important?

Water is the most important thing we need after the air. An average person can live less than a week without water. We need several liters of water every day for our bodies to function properly.

The cells in our bodies die from the lack of water. However, this water has to be pure to make sure that our health is not threatened by it. That is why treating the water is important.

Many viruses and bacteria make their homes in water. They can spread through the water we drink. Drinking water that is laden with germs of diseases creates painful symptoms.

Diseases such as diarrhea, cholera, dysentery, etc spread through the water. Water treatment is important to make sure they are eliminated from the drinking water.

Water can have a high amount of heavy metals present in it. For example, the groundwater in many areas of Bangladesh has a high concentration of Arsenic. Lead, chromium, and other heavy metals can be present in the water too.

Heavy metals can create poisoning in our bodies that may prove to be fatal in complicated cases. The water should be thoroughly treated to eliminate heavy metals.

There can be other impurities such as dust, debris, and solid waste present in the water. They can render the water unsafe to drink. The presence of these impurities hampers the taste, smell, and color of the water.

Water treatment can significantly improve the quality of the water. It can improve the taste and smell of water and make it the safest to drink.

Seven important steps are commonly followed to rid the water of impurities. You might have wondered, but what are the 7 steps for water treatment? These popular steps are discussed below, so you can have a clear idea of how water gets treated. You need to know, so you can inquire whether the water in your area is getting properly treated or not.

1. Ion Exchange and Coagulation:

   Ion exchange is done by making the contaminants remove ions with other elements and getting rid of the contaminants. This way, hard water can be softened.

   In coagulation, coagulants are used to make the contaminants get clumped together and collect at the bottom of the container. That way, they can be separated from the water to purify it.

2. Sedimentation: 

   In the sedimentation tank, water is agitated by the wind to make use of gravity and separate solids. The solids sink to the bottom of the tank in this process and can be separated easily.

   Only a little amount of chemicals is needed in this stage. This is one of the primary stages that is commonly used in water purification.

3. Filtration and Granular Activated Carbon: 

   In this stage, granular activated carbon is used to absorb some organic chemicals. These carbons can soak up the contaminants on their surface.

   The filtration stage can remove dust and debris from the water. It purifies the water further before sending it off to the next step to be better purified.

4. Disinfection:

   For disinfection, chlorine and ultraviolet rays are commonly used. The water might be passed through a chlorine-rich container that can kill off germs and disinfect the water.

   Ultraviolet rays are also capable of killing germs and disinfecting the water. Many municipalities prefer to use ultraviolet rays for disinfection to reduce the use of chemicals.

5. Carbon Filters:

   In this stage, carbon filters are used to remove organic chemicals, heavy metals, pesticides, etc. Carbon filters are excellent at removing chlorine from the water.

   It would be a good idea to run the water through carbon filters after it has been passed through a chlorine-rich container for disinfection purposes. These filters can soak the chlorine from the water and make it safer to drink.

6. Reverse Osmosis: 

   In this stage, the water is purified on a molecular level. This process makes sure that no particle that is larger than a water molecule can escape into the purified water.

   Reverse osmosis filters can filter out germs and bacteria from the water and reduce the risk of water-borne diseases. At this stage, the water is in its purest form.

7. Store Purified Water:

   The purified water is then stored in tanks where it cannot be contaminated again. These tanks should be kept covered and well-maintained so that dust and germs may not collect in them.

   From these tanks, the water gets to the supply line, and finally, people can collect it from their faucets. To get the purest water, people should make sure that the tanks and water lines in their homes are kept clean.

The water should pass all of these seven stages perfectly to be counted as safe. The machines used in the steps have to be cleaned from time to time to stop the damage from contaminants. The chemicals used in these stages have to be of good quality, and an unsafe amount of them should not be present in the water.
