What is Fluoride?
Fluoride is an ion present naturally in many waters and added deliberately in some UK supply areas.
Why test for it?
Fluoride is measured where the natural or added concentration is of interest, including for filtration performance work.
Where can it come from?
- Natural geology
- Water fluoridation schemes in some areas
- Certain industrial discharges
How is it measured?
Determined by ion chromatography or ion-selective electrode, reported in mg/L.
What does my result mean?
Fluoride is a common parameter in filter evaluation because reduction performance varies significantly between technologies.
