Several methodologies are used to produce the Black Berkey Filter elements.
MICROFILTRATION
The first line of defense is that Berkey elements comprise a proprietary formulation of more than six different media types, all constructed into a very compact matrix containing millions of microscopic pores.
These pores are so small that they create what we refer to as a “Tortuous Path,” which dramatically reduces the presence of trihalomethanes, inorganic minerals, heavy metals, pharmaceuticals, VOCs, petroleum products, perfluorinated chemicals, rust, silt, sediment, radiological contaminants, and more.
These paths are so small that pollutants cannot physically pass through them and become trapped, eliminating them from drinking water. This process is known as microfiltration.
ADSORPTION
Secondly, our media formulation uses unique adsorption and absorption properties. Adsorption creates an ionic barrier similar to surface tension. This barrier is perfectly suited to the micro-porous water filter because it effectively blocks contaminants smaller than the pore size.
Next, heavy metal ions (metal ions) such as cadmium, chromium, copper, lead, mercury, aluminum, and other dangerous heavy metals are extracted from the water through an Ion exchange process, attracting and transforming them by electrically bonding to the media.
FLOW RATE
Finally, Berkey systems effectively remove contaminants from water due to their extremely long “contact period.” Other filtration systems rely on pressure that forces water molecules through the 60-90 PSI elements.
These water molecules contact the filter media for a mere fraction of a second. By comparison, water molecules passing through the Black Berkey elements are gently drawn by gravity and remain in contact with the media for a long period.
This allows the filter media to capture contaminants more efficiently. This advanced technology was developed, refined, and proven through years of diligent, investigative research and testing performed by water purification specialists, researchers, and engineers.
