The History of the Doulton Ceramic Filer 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 thc 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 yeaxs,
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". Tt~day 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
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
are the only ceramic fillers available today to be certified under both of these
standards.
Doulton holds accreditation / certification / approval from:
· ISO- 9002
· The World Health Organization
· Department of Health [Toronto, Ontariol
· Counties Public Health Laboratories [London, England]
· Japan Food Research Laboratories
· University of Arizonn (USA)
· Spectrum Labs (Minneapolis, USA)
· National Sanitation Foundation (standards 42 & 53)
· Over 50 Independent Laboritories Worldwide
They are currently sold and used in over 150 countries throughout the world.
