Chlorine
A disinfectant residual that affects taste and odour.
What is Chlorine?
Chlorine is used to disinfect mains water and is often present as a low residual at the tap.
Why test for it?
Chlorine reduction is one of the most commonly claimed filter functions, so it is a frequent parameter in product testing.
Where can it come from?
- Water treatment disinfection
- Booster dosing in distribution
- Secondary disinfection in buildings
How is it measured?
Free and total chlorine are determined promptly after sampling, since the residual decays. On-site or immediate laboratory measurement is used.
What does my result mean?
Chlorine results are time-sensitive; the interval between sampling and measurement is recorded with the result.
