Improvements in the Manufacture of Materials for Use in the
Filtration and Purification of Impure Water and other
Liquids.
We ARTHUR ANGELL of the County Laboratory Southampton in the County
of Hants Ph. D., F.1.C. and FRANK CANDY of No. 56 Nightingale Lane Balbam
in the County of Surrey Manufacturer do hereby declare the nature of this
invention to be as follows:-
Our invention consists in the improvements hereinafter described in the manu-
facture and preparation of materials for use in the filtration and purification of
impure water and other liquids the object of our said invention being to produce
materials having greater porosity and higher oxydising properties than are
possessed by materials heretofore known and employed for such purposes.
According to our said invention we take a quantity of the dust or powder
produced in the granulation of the porous substance manufactured as described in
the Specification of Letters Patent No. 13818 of 1884 granted to one of us namely
the aforesaid Arthur Angell or we take a quantity of the dust or powder produced
in the granulation of the porous substances manufactured as described in the
Specifications of Letters Patent No. 15948 of 1885 and No. 1793 of 1886 which
said Letters Patent were granted to the other of us namely the aforesaid Frank
Candy and we mix the said dust or powder with powdered or finely granulated
manganese and clay in various proportions according to the plasticity of the clay
and the quantity of powder to be used and to the said mixture we add water or
organic matter such as tar or a solution of organic matter such as treacle and we
mould the whole into blocks or lumps and dry them or partially dry them and
place them in a retort or oven or kiln and heat them to a sufficient degree to
render them capable of being readily granulated and to impart to them sufficient
hardness to enable the granules to withstand the wear and tear to which filter beds
are subjected.
In some cases we omit the powdered porous substances herein before referred to
and produce a material for the purpose hereinbefore stated by mixing together the
other matters hereinbefore named and referred to and treating the mixtures as
hereinbefore described.

of Hants Ph. D., F.I.C. and FRANK CANDY of No. 56 Nightingale Lane Balham
in the County of Surrey Manufacturer do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
Our invention consists in the improvements hereinafter described in the manu-

impure water and other liquids the object of our said invention being to produce
materials having greater porosity and higher oxydising and purifying properties
than are possessed by materials heretofore known and employed for such

are subjected.
In some cases we omit the powdered porous substances hereinbefore referred to
and produce a material for the purpose hereinbefore stated by mixing together the
other matters hereinbefore named and referred to and treating the mixtures as
hereinbefore described.
Where the filtrant is required to be used in a granulated form we break the
carbonized or calcined lumps or blocks into pieces or granules of the required size.
The use of the ingredients hereinbefore named and referred to in any particular
proportions is not of importance the proportions hereinafter stated have however
been found to produce satisfactory results.
Dust or powder of any one or more or
all of the patented porous substances
hereinbefore referred to
Powdered or granulated manganese
Dried and powdered clay
Tar
100 parts by weight.
5 parts by weight.
100 parts by weight.
2 parts by weight.
Water sufficient to convert the whole into a mass of such consistence as to
admit of thorough incorporation of all the ingredients.
Where a solution of treacle is to be weed in lion
L

page_text: solution consisting of say ten parts by weight of treacle to ninety parts by weight
of water and add sufficient thereof to convert the whole into a mass of such a
consistence as to admit of thorough incorporation of all the ingredients.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that we
claim :-
First. A filtrant consisting of a carbonized or calcined mixture of any one or
more or all of the porous substances hereinbefore referred to and manganese and
clay and organic matter of the kinds hereinbefore referred to.
Secondly. A filtrant consisting of a carbonized or calcined mixture of powdered
manganese and clay and organic matter of the kinds hereinbefore referred to.
