Includes: Two (2) Black Berkey. Two - (2) PF-2 Fluoride & Arsenic Reduction Filter's.
The Berkey® stainless steel chambers are assembled in the USA from US and imported parts. The Black Berkey® Purification Elements are made and assembled in the USA. Comes standard with 2 Black. Purification Elements, but can be expanded up to 4 elements. The versatile Big Berkey® System is ideal for small to medium families, and for use during travel, outdoor activities, or unexpected emergencies.
Constructed of highly polished AISI 304 stainless steel. Storage capacity of about 2.25 gallons (8.5 liters). Upper chamber nests within the lower chamber for transport and stands only 13 in height. Purification Elements (in upper chamber).
System includes upper and lower stainless steel chambers, 2 Black. Purification Elements (expandable up to 4), 1 stainless steel lid, 1 spigot, rubber gasket to protect the base, 2 wingnuts, 2 washers, 1 priming button, and 2 blocking plugs.Height when in use: 19.25. For normal everyday use, this system easily serves: 1-4 people.
Fully configured, this system can serve up to 85-170 people a day, during an emergency. Purification Elements, the Big Berkey® System can produce up to 3.5 gallons (13.3 liters) per hour. Purification Elements, the Big Berkey® System can produce up to 7.0 gallons (26.5 liters) per hour. And Arsenic Reduction Filters may be installed in the lower chamber of this system if desired. Flow rate calculated with upper chamber full to top.
Flow rate decreases as water level declines. The Black Berkey Purification Elements are made and assembled in the USA. Purification Elements are the leader in gravity-fed water purification, backed by independent testing.
Purification Element formulation has been tested by State and EPA accredited laboratories to exceed NSF/ANSI Standard 53. Each set of 2 Black Berkey. Purification Elements with 2 washers, 2 wing nuts, and 1 priming button. Installs in the upper chamber of any Berkey system.
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. 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. 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.
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. In other words the Black Berkey® elements removed more aluminum from the water than was added by the PF-2 elements.
