Importance of Chlorine in Water Purification

Chlorine in the world of water purification, fights off harmful microbes and pathogens to keep our drinking water safe. It makes sure illnesses like typhoid fever don’t stand a chance.

Drinking water that’s not clean can make us sick, which is why this process of adding chlorine, called chlorination, is super important.

Now, you might wonder where these harmful microbes and pathogens come from. They can sneak in from places like factories, farms, and even natural sources, bringing all sorts of contaminants with them.

Keeping the chlorine level below 4 mg/L means our water isn’t just safe but also pleasant to drink.

But what happens if we go over the limit? High levels of chlorine could be tough on some folks, especially those with sensitive systems. That’s why water companies are constantly checking the water to make sure it stays within the safe zone.

The great news is, that when chlorine levels are just right, we can drink our water without fear, knowing it’s our ally in the fight against waterborne diseases.

Let’s explore how the magic of chlorine keeps our storage tanks sparkling clean and our drinking water safe. Think of chlorine as the protective shield that helps in battling germs and keeps our water pure.

First off, let’s talk about the secret weapon: shock chlorination. Shock chlorination is a powerful chlorine mix that zaps those germs into oblivion. You’ll want to aim for a chlorine strength of 50-100 parts per million (PPM).

Here are the main steps:

  1. Create the Potion: Start with liquid chlorine, commonly found as bleach. It’s the base of your powerful germ-fighting solution.
  2. Prep the Battlefield: Before you unleash your chlorine mix, make sure the tank is clean. This ensures no hidden germs escape the cleansing.
  3. Unleash the Power: Pour the chlorine solution into the tank, letting it work its magic. This is where the battle against germs happens, disinfecting every drop of water.
  4. Cleanse the Arena: After the chlorine has done its job, it’s time to flush the tank. This removes any leftover chlorine, ensuring the water is safe to drink.
  5. Keep Watch: Regularly test the water for chlorine levels. It’s like having a superhero watchdog, making sure the water stays safe and clean.

For those tanks that are just being introduced to the world or have recently been through a germ battle, keeping the chlorine level within 50-100 PPM is key.
