How Berkeys Work

More than just a Water Filter it is a Water Purifier

Any Berkey system containing Black Berkey elements are certified to the Water Purifier classification. Actually, Berkey Water Purifiers far exceed the bacteria standard for purifiers by removing 99.9999999% or to an incredible log 9 reduction of pathogenic bacteria.  In fact, the Black Berkey® purification elements have been tested with more than 10,000 times the concentration of pathogens per liter than is required by the standard test protocol.  This concentration of pathogens is so great that the post filtered water should be expected to contain 100,000 or more pathogens per liter (99.99% reduction – the requirement for pathogenic removal). Incredibly these elements removed 100%. Absolutely no pathogens were able to be cultured from the effluent nor could any be detected using an electron microscope, setting a new standard in water purification.  To our knowledge no other water filtration device in the world can match that claim.

Advanced Scientific Design

So how does the Black Berkey purification element accomplish these amazing results?  Thru exhaustive research and the incorporation of several scientific methods into its design, this makes the Black Berkey® the most unique and finest purification element in the world.  The Black Berkey® is a formulation of more than six unique filter media types which are constructed and compressed into a very tight matrix with literally millions of microscopically sized pores.  These pores are so tiny that they create what is referred to as a ”torturous path” thorough which the contaminated water must pass before exiting the filter.  As water works its way slowly though this matrix it is stripped of all micro-organisms and large molecules simply because the pores are so small that viruses, pathogenic bacteria, cysts, parasites, sediment and sedimentary minerals are unable to pass through them.  This process is known as micro-filtration.

Also due to the unique bactericidal and virucidal properties of the media bacteria, viruses, cysts and parasites are killed making the Black Berkey a powerful self-sterilizing purification element to further protect your family from harm.

Next, the special formulation of our media causes a class of chemical reactions known as sorption to occur, adsorption, absorption and ion exchange, which further purifies the water.  First is adsorption, unique media properties cause the bonding of some molecules. Bio-molecules or dissolved solids to its surface mainly through surface tension.  Next, some contaminants are literally absorbed or taken into the media itself.  Last heavy metal ions are extracted through an ion exchange process in which they become  “electrically bonded” to the media.

But the real key is the micro-fine pore design coupled with the longer contact time created by the gravity fed purification system.  Since the water molecules are traveling though the filter at a much slower rate, due to the ‘”torturous path” of the micro-fine pores and the slow pull of gravity, than conventional pressurized filtration systems, which typically force water thru at 60 to 90 PSI, the water molecules have a much longer contact time with the media in a Black Berkey purification element allowing more contaminates to be extracted through the sorption processes described above.

Amazingly, this little purification powerhouse is so advanced it is even able to remove red food coloring from water without removing the beneficial minerals your body needs. This advanced technology was developed, refined, and proven through years of diligent, investigative research and testing performed by water purification specialists, researchers and engineers.  So while the Black Berkey is simple in function, it is complex in its science.  It combines modern state-of-the-art technology with the highest quality materials replicating the best purification processes known in nature.  The end result is the freshest, healthiest and most delicious drinking water available for just pennies a day…
