British Berkefeld Water Filters Elements

MTBE REDUCTION PF4 FILTERS


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 - butane toluene ethylene xylene and TOC - total organic carbons) are adsorbed more readily, and MTBE often slips by standard carbon filters, ending up in the filtered water. The PFE-1 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 PFE-1, secured as a post filter, to more efficiently remove MTBE.


The PFE-1 filter 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. *The reduction efficiency of the PFE-1 filter is greater than 95% and each four-oz. cartridge, of the four cartridge set, has an approximate capacity of 1,200 gallons even if contamination level is as high as 600ppb! MTBE removal is achieved via a special medium called "AquaBond". Its unique pore structure, created using a proprietary process, is designed for increased adsorption capacity for trace organics and weakly adsorbed species, such as MTBE, DBCP, THM's, pesticides and herbicides. The "AquaBond" granular medium has proven superior adsorption capacity compared to standard activated coal-based carbon. Generally, the longer the contaminated water is in contact with the effective medium, the greater the removal of MTBE. This is known as the "Trickle Method". Because the PFE-1 filters used in conjunction with a British Berkefeld gravity filter incorporate the "Trickle Method", it is the preferred system for removing MTBE from contaminated drinking water sources.
