Doulton Sterasyl® Ceramic Filtration Efficiency
Doulton ceramic water filters have been continually manufactured for
over 170 years. The first water filters were manufactured in the early
1800’s at Doulton & Co.’s Lambeth works on the banks
of the River Thames. At that time Cholera outbreaks were a common
occurrence and Doulton water filters soon began to play a vital
role in controlling this disease.
The early innovation associated with the
Doulton name has continued well into the twenty first century with
an increasingly sophisticated range of water filtration products
being developed to meet the needs of modern water purification systems.
Doulton ceramic water filters provide clean, safe and affordable wholesome drinking water for residential, industrial and institutional
use - for travel and marine purposes, disasters and emergency situations.
• Doulton ceramic water filtration element exceeds US Public Health CDC/EPA guidance on drinking water for
people with severely weakened immune systems. Far exceed EPA three log cysts removal standard.
|N.J. Butler, M.Sc., F.I.Biol., A.I.F.ST. --
tested the Royal Doulton ceramic filtration element for bacteria removal efficiency, and stated: "Providing
the physical integrity of the filter elements is intact these
can be used to produce sterilized water."
|Absolute (defined as >99.99%) filtration rating
|Nominal (defined as >99.9%) filtration rating
||0.5 to 0.8 micron
|Salmonella Typhi (Typhoid)
|Vibrio Cholerae (Cholera)
This data, from tests conducted by independent laboratories, demonstrates
the removal capabilities of Doulton's ceramic purification element. This
does not imply that these contaminants are present in individual water supplies.
It should be clearly understood that the concentration of bacteria
fed to the filtration element is artificially high in order to simulate
a challenging test for the ceramic element. The most aggressive
"real life" condition would normally be at least 1000 times less severe.
|Professor A. Dodin, a scientist at the prestigious Institute Pasteur,
tested the Doulton filtration element against cholera and other pathogenic bacteria and stated: "
The Doulton filtration element is excellent for the prevention of bacterial contamination."
