- Fluoride: Sodium Fluoride, Sodium Fluorosilicate, Fluorosilicic Acid (aka Hydrofluorosilic Acid):
Testing for fluoride was based on 20-30ppm of the ion in the influent aqueous solution at a flow rate of no more than 3 gpm per cubic foot of media. Results of ‹1ppm of the fluoride ion in the effluent were typical for the media (>95% reduction). Under optimum conditions, effluent concentrations of less than 50 ppb were readily achieved (>99.75% reduction).
Arsenic: V and pre-oxidized Arsenic III:
This product uniquely targets the entire family of arsenic oxide anions as well as the arsenic cations.
- Other residual heavy metal ions
PF-2 Fluoride and Arsenic reduction Filters are designed to be used in conjunction with the Black Berkey Purification Elements only.
Number of PF-2s in the bottom chamber must match the number of Black Berkey Purification Elements in the top chamber; for example, 4 Black Berkey Purification elements would require 4 PF-2 Filters.
If the system is refilled about one time per day, the PF-2’s should be replaced annually, if the system is refilled about twice per day, the PF-2’s should be replaced about every six months). Actual capacity is dependent on the presence of other competing contaminants in the source water. High levels of Fluoride, arsenic and heavy metals may reduce the capacity and efficiency of the elements.
