The Berkey purification system removes pathogenic bacteria, cysts and parasites while extracting chemicals including herbicides, pesticides, organic solvents, VOCs, detergents, cloudiness, silt, sediment, foul tastes and odors. It reduces heavy metals such as cadmium, chromium, copper, lead, mercury, aluminum, nitrates and nitrites WITHOUT removing the BENEFICIAL minerals your body needs.
The unique design of Black Berkey purifier elements combines the tried and true process of micro-porous filtration together with modern state-of-the-art technology and the highest quality materials bringing you the finest water purification system available anywhere at such an economical value. The micro-pores within the self-sterilizing and cleanable Black Berkey purification elements are so incredibly small that pathogenic bacteria cannot pass through them.
The media inside the Black Berkey elements removes contaminants by a surface phenomenon known as adsorption which results from the molecular attraction of substances to the surface of the media. These exclusive purification elements are also impregnated with proprietary media that promote ionic 'absorption' of pollutants within the micro-porous elements.
Another reason Berkey systems are so effective in removing contaminants from water is the extremely long 'contact period'. Other filtration systems rely on water pressure that forces water molecules through the filters at 60-90 PSI. In such systems, individual water molecules come in contact with the filter media for a mere fraction of a second. Water molecules passing through the micro-pore structure of the Black Berkey® purification elements are drawn by gravity and stay in contact with the media for several minutes (the Tortuous Path), making the Black Berkey filter media much more efficient in capturing contaminants.
Berkey purifiers using the Black Berkey purification elements have been proven to reduce pathogenic bacteria (including E. Coli, Klebsiella, Pseudomonas Aeruginosa, Giardia and Cryptosporidium) by 99.99999%. When contamination levels exceed one billion pathogens per liter of water (10,000 times the density of contamination used in the standard test protocol for bacteriological removal) they're classified as "TNTC" (too numerous to count).
Under normal testing protocol, one pathogenic organism is tested at a time, each with a fresh purifying element. For documented tests on the Berkey system, however, the laboratory was directed to combine three separate pathogenic TNTC cultures. Tested under this extreme contamination level, absolutely no pathogens were able to make it through the purification elements.
The laboratory then incubated the water, and nothing grew. When the filtered water was viewed under an electron microscope not even in-viable (dead) microbes were detectable - nothing was present but pure H2O. Furthermore, contaminants reduced to below detectable limits include Trihalomethanes, Radon 222, and volatile organic compounds including Benzene, 2,4-D, Heptachlor, MTBE, Styrene, Tetrachloroethylene and Toulene, among many others. |
