British Berkefeld SS-4 Emergency Water Filter System
British Berkefeld SS-4 Emergency Water Filter System The original gravity fed water filtration system. Get up to 60,000 gallons of clean drinking water where and when you need it! (SS-4) Just pour untreated water into the British Berkefeld Gravity-Fed water filter, and get up to 60,000 gallons of clean drinking water when and where you need it! Designed for emergency use and camping situations, the British Berkefeld four filter system turns untreated, contaminated water into pure, fresh-tasting drinking water. The 20" H x 8.5" W design weighs only 5.5 pounds for easy portability and storage. Constructed of high grade polished stainless steel, this two-piece unit is extremely durable yet easy to clean. It processes approximately one gallon per hour and holds 2.4 gallons. The Doulton "Super Sterasyl" ceramic filtration system removes up to 99.99% of particles, cysts, parasites and pathogenic bacteria including e coli, cryptosporidium, gardia and salmonella typhii. The silver-impregnated system also reduces chlorine, rust, sediment and organic chemicals. Total filter capacity is 2,500 to 15,000 gallons depending on the source water. The carbon matrix interior provides additional support in removing chemicals and other bad taste and odor elements. Meets NSF standards, ISO-9002 quality standards, British 5750 quality standards and England’s Water Research Council performance standards. Detailed assembly and operating instructions are included. |

PF-4 Post Filter Reduction Element
PF-4 reduction elements are designed for use in conjunction with British Berkefeld and Berkey series of water filters to adsorb the following four unwanted elements most commonly found in drinking water.
MTBE (Methyl-tertiary-butyl-ether)
Fluoride
Lead
Arsenic
PF-4 filters are also designed to adsorb:
DBCP (Dibromo-chloro-propane)
THM’s (trihalomethanes)
Herbicides & Pesticides
Heavy Metal ions
Installation:
Assemble the water filter as per the water filter assembly instruction. On the underside of the upper chamber locate the stem of each ceramic filter (do not remove the wing nut holding the ceramic filter in place). With clean hands, remove blue caps and screw a PF-4 filter onto each filter stem (the blue arrow should point away from upper chamber) giving five full revolutions. Do not screw more than five revolutions as this may damage the internal media screen. When complete, seat upper chamber on top of the lower chamber. Fill upper reservoir. When the lower reservoir is full, discard the first batch of water, which may contain process dust. (Note: when lower chamber is full of water, the PF-4 filters will be immersed).
Technical Information:
MTBE: The PF-4 is manufactured to exceed ANSI/NSF Standard 53 which requires that MTBE be reduced by at least two thirds from an influent rate (water going in) of 15ppb to an effluent rate (water going out) of less than 5ppb (> 95% reduction*). LEAD: Tests have shown that when 2000 gallon of influent water at a concentration of lead of 150-200 ppb pass through 200 grams of media at a flow rate of 1gpm, the lead level was reduced to less than 1ppb (>99% reduction). FLOURIDE: 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).
Replacement:
Under normal conditions it is recommended that PF-4 elements be replaced at six-month intervals ( Actual capacity is dependent on the presence of other competing contaminants in the source water. High levels of total organic carbons, volatile organic compounds or certain inorganic minerals may reduce the capacity and efficiency of these elements. )*. Note: do not boil this element.
MTBE (Methyl-tertiary-butyl-ether) is the most common oxygenated fuel additive used in reformulated gasoline. Contamination of groundwater with MTBE is a rapidly growing problem in 49 U.S. states. In drinking water, even trace amounts of MTBE can cause taste and odor problems, which may lead to nausea and dizziness. The potential long-term health effects of MTBE are not understood at this time, however, initial studies indicate MTBE may cause kidney and liver problems. MTBE removal from water is a challenge because it is very soluble in water and must compete with other organics for binding sites on the filter medium. These other contaminants (BTEX - and TOC - total organic carbons) are adsorbed more readily, and MTBE often slips by standard carbon filters, ending up in the filtered water. The PF-4 filter has been specifically designed to remove MTBE from drinking water when used in conjunction with a British Berkefeld gravity filter system. The media within the Super Sterasyl filters, in the upper chamber, capture the more strongly adsorbed BTEX and TOC's. This permits the downstream PF-4, secured as a post filter, to more efficiently remove MTBE.
