In the wake of natural disasters and during pandemics, rapid and effective purification of water becomes critically important. Contaminated water sources can quickly lead to widespread disease outbreaks, compounding the challenges affected communities face. Aquatabs Granules, as a non-effervescent granulate approved for human consumption, provide a vital solution by enabling the swift and efficient disinfection of large volumes of water.
1. Weigh out and dissolve 20g of Aquatabs Granules in 1 litre of water. (where a weighing scales is not available, the guideline is 6 level teaspoons – approximately 20g)
2. Stir to dissolve. The 1% (10,000mg/l available chlorine) solution is used to disinfect larger quantities of water as follows:
Volume of 1% solutions to be added to:
| Chlorine Dose Required | 10 Liters | 100 Liters | 1000 Liters | 10 000 Liters | 100 000 Liters |
|---|---|---|---|---|---|
| 1 mg/l | 1 ml | 10ml | 100ml | 1 litre | 10 litres |
| 5 mg/l | 5 ml | 50ml | 500ml | 5 litre | 50 litres |
Note: 1mg/l = 1ppm available chlorine.
3. Pre-treatment should ensure that the water turbidity is less than 5 NTU before chlorinating.
4. Ensure that a minimum contact time of 30 minutes is allowed before consumption.
5. Ensure a thorough mix, by recirculation where appropriate.
6. Always test for residual chlorine levels. It is desirable to leave a residual chlorine level of 0.3-0.5 mg/l after 30 minutes of contact.
7. During outbreaks it is recommended that chlorine residuals should be maintained as follow:
Treatment of drinking water is usually carried out using a stock solution at 1%. For virus control, disinfecting solution is required at 0.5% (5000 mg/l or ppm)
