How to Use

Directions for use and dosage for 1% available chlorine solution

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% solution to be added to:

Chlorine Dose Required 10 Litres 100 Litres 1,000 Litres 10,000 Litres 100,000 Litres
1 mg/l 1ml 10ml 100ml 1 litre 10 litres
5 mg/l 5ml 50ml 500ml 5 litres 50 litres
10 mg/l 10ml 100ml 1 litre 10 litres 100 litres

Note: 1mg/l = 1 ppm 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 contact.

7. During outbreaks it is recommended that chlorine residuals should be maintained as follow:

0.5 mg/l at all points in the supply
1.0 mg/l at standposts and wells
2.0 mg/l in tanker trucks at filling

Treatment of drinking water is usually carried out using a stock solution at 1%. Water for hand washing and sanitising is required at 0.05% (500 mg/l or ppm) For virus control, disinfecting solution is required at 0.5% (5000 mg/l or ppm)
