User notes
  • Chlorine granules have a shelf life of approximately 2 years from manufacture date.
  • NOTE: Always check and confirm the percentage of available active chlorine in the product before mixing a solution

Chlorination method:

  1. Weigh out and add 20g (56%) of granules to 1 litre of water. Stir to dissolve. (1 teaspoon is very approximately 14g)
  2. The 1% (10,000 mg/l available chlorine) solution is used to disinfect larger quantities of water - see table below.
  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
