Installs in the upper chamber of any Berkey system.
Durability: Each Black
Berkey
®
Element is designed to purify approximately 3,000 gallons of water before needing replacement; 2 elements in a Berkey system will purify approximately 6,000 gallons of water before replacement is recommended
Re-cleanable and self-sterilizing during the life of the element
Elements come with a 2-year, pro-rated warranty
The powerful Black Berkey
®
purification elements also remove or reduce viruses, pathogenic cysts, parasites, harmful or unwanted chemicals such as herbicides and pesticides, VOCs, detergents, organic solvents, trihalomethanes, cloudiness, silt, sediment, nitrates, nitrites, heavy metals, foul tastes and odors, yet they leave in the healthful and beneficial minerals that your body needs
.
PF-2 Fluoride & Arsenic Reduction Filter
PF-2 reduction elements
are designed for use in conjunction with
Black Berkey®
water purification elements to adsorb the following unwanted elements found in drinking water.
• Fluoride
• Arsenic V and pre oxidized Arsenic III
• Other residual heavy metal ions
TECHNICAL INFORMATION:
FLUORIDE
: 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
: This product uniquely targets the entire family of arsenic oxide anions as well as the arsenic cations.
REPLACEMENT
:
Under normal conditions it is recommended that each set of two
PF-2
elements be replaced after 1,000 gallons (The
Berkey Light™
is 2.5 gallons therefore the
PF-2
filters should be replaced after 400 refills. 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.
NOTES
:
1)
Do not
boil this element.
2)
PF-2
elements reduce filtration flow rate by 15-20%.
3) The media used in the
PF-2
filter elements contains high-grade activated aluminum oxide, which currently is the most efficient media available for extracting fluoride from water. Below are the results we obtained when testing the
PF-2
elements (the water was not pre-filtered through the
Black Berkey®
elements). The reduction over time is due to additional residual process dust being washed free from the
PF-2
elements as the system is used. To give a scale for comparison purposes we include test results from a national brand toothpaste and water boiled in an aluminum pan.
• National brand toothpaste 52.878 ppm aluminum
• Water boiled in an aluminum pan for five minutes: 2.791 ppm aluminum
•
PF2
after conditioning (5 cycles): .178 ppm aluminum
•
PF2
after 10 Cycles: .037 ppm aluminum
•
PF2
after 20 Cycles: .029 ppm aluminum
While the above results indicate that the residual process dust adds a minute amount of aluminum to the water, the
Black Berkey®
purification elements reduce aluminum from the water. We tested water that naturally contained .320ppm aluminum and filtered it through the combination of the
Black Berkey®
and the post conditioned
PF-2
filtration elements (5 cycles). The results showed a net reduction in aluminum contamination (Raw influent: .320ppm - Effluent after passing through the
Black Berkey®
and
PF-2
elements: .232ppm). In other words the
Black Berkey®
elements removed more aluminum from the water than was added by the
PF-2
elements
