Berkey Water Purification Process
Several well known methods are used to produce the Black Berkey purification elements used to produced, clean, fresh Berkey water. These methods are combined and blended to produce a unique filter process that competitors just can't match.
The first line of defense is that the Berkey purification elements are composed of a formulation of more than six different media types, all constructed into a very compact matrix containing millions of microscopic pores. These pores are so minute that they produce what we refer to as a torturous path that pathogenic bacteria, cysts, parasites, sediment and sedimentary minerals must travel through. These paths are so small that pollutants physically cannot pass through them, and become trapped, eliminating them from your drinking water. This is known as microfiltration.
Secondly our media formulation uses unique adsorption and absorbtion properties. Adsorption works to create an ionic barrier similar to surface tension. This barrier is perfectly suited to the micro-pourous water filter because it effectively allows the tiny pores to block water contaminants that are smaller than the pore size itself. This blocking process is how the Berkey water purifier is able to remove submicron viruses that other brands of water filters cannot -- without the use of obnoxious chemicals like iodine or chlorine.
Next, the heavy metals ions (mineral molecules) are extracted from the water through an Ion exchange process where they are attracted to and transformed by electrically bonding to the media. Finally, because of their gravity flow nature, water molecules can take several minutes to pass through the filter elements, whereas these water molecules in other filtration systems can pass through in only fractions of a second. This longer contact time between the water molecules and the filter media, provides much greater removal rates of harmful water contaminates not obtainable through conventional pressurized water filtration methods.
As you can see, Berkey water is so phenomenal because our filters incorporate several different scientific methods to produce unmatched drinking water quality. We are able to do all of this and still maintain simplicity. All that you, as a Berkey user, are required to do is simply pour water into the top of the filter chamber. All of the processes mentioned above will continue to work for you behind the scenes for many years to come. This long filter life allows you to produce purified drinking water for pennies a gallon.
