How to Purify Polluted Water at Home

Polluted water can pose serious health risks. Fortunately, there are simple and affordable methods you can use at home to make water safe for drinking. These techniques help remove bacteria, chemicals, and dirt from contaminated water.

1. Boiling

Boiling is one of the most effective ways to kill harmful bacteria, viruses, and parasites. Bring the water to a rolling boil for at least 5 minutes before cooling and storing in a clean container.

2. Filtration

Using household water filters or DIY sand and charcoal filters can remove dirt and some bacteria. Always clean or replace filter cartridges as recommended.

3. Chlorination

Add a few drops of household bleach (without additives) per liter of water, mix well, and let it sit for 30 minutes. This kills most pathogens but doesn’t remove heavy metals or chemicals.

4. Solar Disinfection (SODIS)

Fill transparent plastic bottles with water and place them under direct sunlight for 6 hours. UV rays help eliminate bacteria and viruses effectively.

5. Alum (Fitkari) Treatment

Stir a small piece of alum into water. Let it sit for 30 minutes. It helps suspended particles settle down, leaving clearer water on top which can be filtered or boiled.

6. Use of Water Purifiers

Install RO (Reverse Osmosis), UV, or gravity-based purifiers for consistent and effective purification. This is the safest method for areas with heavily polluted water.

Conclusion

Clean drinking water is essential for good health. By using these simple home methods, you can reduce the risk of waterborne diseases and ensure your family's safety.
