Explain Disinfection Process at household level.

At the household level, disinfection processes are typically employed to ensure the safety and potability of drinking water. One common method for disinfecting water is by using chlorine-based disinfectants, such as chlorine bleach or chlorine tablets.

To disinfect water using chlorine bleach:

1. Begin by filtering the water to remove any visible particles or sediment.
2. Add the appropriate amount of chlorine bleach to the water. The recommended dosage may vary depending on the concentration of chlorine bleach and the volume of water being treated.
3. Stir the water to ensure thorough mixing of the chlorine bleach.
4. Allow the water to stand for a specified contact time, typically around 30 minutes, to allow the chlorine to effectively disinfect the water.
5. After the contact time has elapsed, the water should have a slight chlorine odor. If not, repeat the dosage and contact time as needed.
6. The water is now disinfected and safe to drink.

It's essential to follow proper dosing guidelines and contact times to ensure effective disinfection while minimizing potential health risks associated with chlorine exposure. Additionally, alternative disinfection methods, such as boiling or using ultraviolet (UV) light, can also be effective at the household level, depending on the availability of resources and infrastructure.
