The
History of the Doulton Ceramic Filter Candle
John Doulton founded
his first pottery in 1815 at Lambreth, England on the banks of the
Thames river. The main products of the original company were ceramic
busts, figurines, canning jars and tableware. Influenced by the unrelenting progress of tho Industrial Revolution, Doulton placed
equal emphasis on industrial applications for ceramic technology. As
early as 1827, this fine china manufacturer was in the water
treatment business, using various earth and clay materials in the
first Doulton water filters,
In 1835, Queen Victoria recognized the present health dangers in her
drinking water and commissioned Doulton to produce a water filter
for the Royal household. Doulton created a gravity fed stoneware
filter that combined the technology of a ceramic filter with the
artistry of a hand crafted pottery water container. In consideration
of her pleasure with the new device, Queen Victoria bestowed upon
Doulton the right to embellish each of its units with the ROYAL
CREST.
John Doulton's son, Henry, introduced the Doulton Manganous Carbon
water filter in 1862, the same year that Louis Pasteur's experiments
with bacteria conclusively exploded the myth of Spontaneous
Generation. This more advanced understanding of bacteria made it
possible to direct Research and Development efforts to the creation
of a porous ceramic capable of filtering out these tiny organisms.
By 1901, King Edward knighted Henry Doulton and honored the company
by authorizing it to use the word ROYAL in reference to its
products. In 1906, Doulton introduced a filter that proved to be
equal to the one Louis Pasteur had developed in France. It was
rapidly adopted by hospitals, laboratories and for use in domestic
water filtration throughout the world. The popularity, and
effectiveness of even the early 20th century designs has resulted in
their continued use in Africa and the Middle East. The range and
efficiency of Doulton domestic water filters has been widely
extended over the years to meet the demands of increasingly
sophisticated uses.
At the core of the Doulton ceramic filter element is the most basic
of elements ...EARTH. This is the same substance which artisans,
first in Asia then in Europe, refined into exquisite porcelain and
pottery of the Shoguns and Kings. This material is Diatomaceous
Earth [D.E.], a fossil substance, made up of tiny silicon shells
left by trillions of microscopic, one celled algae called diatoms
that have inhabited the waters of the earth for the last 150 million
years,
Diatoms have one property that sets them apart from other algae.
They weave microscopic shells which they use for the protection and
locomotion. These shells are covered with a pattern of tiny holes so
regular that even the slightest change in their design usually
signifies a different species. As the diatoms died, their. shells
survived, slowly piling up in deposits at the bottom of geological
lakes and lagoons. When these lakes dried up, what remained were
huge deposits of "diatomaceous earth". Today there are
over 1500 uses for Diatomaceous Earth, from abrasives for
toothpaste, filtering agents for water and milk, heat insulators for
kilns, to polishing agents in nail polishes, and many more.
The latest designs of Doulton filter elements incorporate
Oligodynamic silver impregnated into a porous ceramic outer shell
[80,000,000 pores] that can trap bacteria down to as low as .22 of a
micron in particle size [1/100,000 of an inch]. Laboratories
consider a filtering medium with an effective pore size of .01
micron to .45 micron to be bacteriologically sterile and .45 micron
to 1.0 micron to be bacteriologically safe. Regrowth of bacteria
that becomes trapped either on the outside of the element or in the
ceramic's pores is controlled by the silver which, on contact with
water, reduces small quantities of positively charged metals ions.
These ions are taken into the enzyme system of the bacteria's cell
and thereby neutralize it. The flow rate of the ceramic filter can
be easily renewed by simply brushing its outer surface under running
water. As the top layer of ceramic and the contaminants are brushed
off and flushed away, a new layer becomes available. This process
can be repeated several hundred times before the ceramic material is
exhausted.
Doulton water filters have been available in the United States since
1983 and are registered with the Environmental Protection Agency [E.P.A.]
and certified by the National Sanitation Foundation [N.S.F] under
Standards 53 and 42 for:
Health Effects,
Turbidity Reduction,
Cyst Removal,
Bacteriostatic Effects,
Particulate Reduction,
Taste and Odor Reduction and
The only ceramic fillers available today to be certified
under both of these
standards.
