You can filter clean water using a combination of physical and chemical methods.
Initial Filtration
The first step in filtering water involves removing visible particles and sediments. You can accomplish this using a simple method such as a DIY water filter or a sieve. This helps get rid of large debris.
Secondary Treatment
After the initial physical filtering, it's crucial to remove microscopic contaminants. Here are several effective methods:
- Boiling: Heating water to a rolling boil for at least one minute kills harmful bacteria, viruses, and parasites.
- Activated Charcoal: Filtering water through activated charcoal removes impurities by adsorption, effectively trapping them within its porous structure.
- UV Treatment: Exposing water to ultraviolet (UV) light disinfects it by killing microorganisms, but it doesn't remove physical debris.
Comprehensive Filtration Process
Combining these methods will lead to a comprehensive water filtration system:
| Step | Method | Purpose |
|---|---|---|
| 1 | Physical Filter | Removes large debris and sediments |
| 2 | Boiling | Kills bacteria, viruses, and parasites |
| 3 | Activated Charcoal | Removes impurities via adsorption |
| 4 | UV Treatment | Disinfects by killing microorganisms |
As suggested in the reference, "use a DIY water filter or sieve, then use boiling, activated charcoal, or UV treatment as a second step". This approach ensures the removal of both physical debris and microscopic contaminants.
