HS-F
Liquid Phase, Activated Alumina for Fluoride Removal
Hydrosil’s HS-F is designed for fluoride removal for water treatment. This activated alumina is an adsorbent of metals as well as fluoride. Regeneration is typically used when media is spent.
HS-F is widely used to remove fluoride in drinking water. There are several programs in the US studying the exposure of fluoride which suggest that high levels of fluoride in water is toxic to human brains. Hydrosil’s HS-F is NSF/ANSI standard 61 certified and therefore can be used for drinking water.
