Purifying storage water, specifically for long-term storage as described in the provided reference, often involves chemical disinfection to make it safe for future use. According to the reference "Preparing Water for Storage", a common method is using unscented liquid chlorine bleach.
Chemical Disinfection Method
The reference outlines a specific technique for treating water intended for long-term storage in clean containers:
- Container Type: Water should be stored in thoroughly clean plastic or glass containers.
- Chemical: Use unscented liquid chlorine bleach. Look for bleach types like Clorox or Purex that contain 4% to 6% sodium hypochlorite. Do not use scented or color-safe bleaches, as they may contain other chemicals.
- Dosage: The recommended dosage is 4 to 5 drops of bleach per gallon of water.
This chemical treatment helps to disinfect the water, making it suitable for extended storage by killing potentially harmful microorganisms.
Applying the Bleach
To apply this method effectively:
- Start with clean, sturdy plastic or glass storage containers.
- Fill the container with water you intend to store.
- Add the recommended amount of unscented liquid chlorine bleach based on the volume of water.
- Securely close the container.
- Shake or gently mix the container to distribute the bleach throughout the water.
Dosage Table
Here's a simple guide based on the reference's dosage recommendation:
| Water Volume | Unscented Chlorine Bleach (4%-6% Sodium Hypochlorite) |
|---|---|
| 1 Gallon | 4 to 5 drops |
Note: This method is primarily for disinfection for storage and assumes the water is already relatively clear of sediment and debris. For cloudy water, pre-treatment (like filtering) might be necessary before disinfection.
This chemical disinfection process, as detailed in the reference, is a practical way to prepare water for emergencies or long-term storage, ensuring it remains safe to drink when needed.
