Year: 1876

page_text: LETTERS PATENT to John Hanson, of Savile Town, near Dewsbury, in the
County of York, Manufacturing Chemist, for the Invention of " IMPROVE-
MENTS IN TREATING SEWAGE AND OTHER FOUL WATER, AND IN DEODORIZING
AND UTILIZING URINE, TO BE USED FOR MANURE."
Sealed the 24th March 1876, and dated the 20th January 1876.
PROVISIONAL SPECIFICATION left by the said John Hanson at the Office
of the Commissioners of Patents on the 20th January 1876.
JOHN HANSON, of Savile Town, near Dewsbury, in the County of York, Manu-
facturing Chemist. "IMPROVEMENTS IN TREATING SEWAGE AND OTHER FOUL
WATER, AND IN DEODORIZING AND UTILIZING URINE, TO BE USED FOR MANURE."
This Invention relates to certain improvements in the method or process of
treating sewage and other foul water, such as that from sewage, dye, tan, or other
similar works or places, and it comprises an improved method or means of
deodorizing and utilizing urine for manure, the first portion of the improvements
having connection with the Invention of " Improvements in the Treatment of
Sewage and in the Manufacture of Manure therefrom," for which Letters Patent were
granted to me bearing date the 28th day of July 1875, No. 2675.
In carrying out my present Invention in order to clarify precipitate, or make
colourless sewage, dye, tan, or other coloured or foul water, I apply thereto or use
the slag, dross, or scoria from blast or metal smelting furnaces, also chalk or whiting
commonly called "Paris white." Any or all of these materials I use separately or
in conjunction with the materials and process described in the Specification of the
before-named Letters Patent. The slag, dross, or scoria and chalk or whiting I
use either ground, crushed, sifted, powdered, granulated, or reduced or made fine
by any convenient method or apparatus, and I mix the same with the sewage or
other foul water, with or without the addition of a suitable quantity of sulphuric
or muriatic acid.
The proportions or quantities that I propose to use of the above-named materials
are: To twelve millions of gallons of the sewage or foul water, about seven tons of
the slag, dross, or scoria; of the black ash, as included under my previous Patent,
about seven tons; and of lime, about six tons; or I may use about six tons of lime,
seven tons of the black ash, and seven tons of the chalk or whiting, with sulphuriq

page_text: or muriatic acid as required. In some cases a change in the above may be required
by using varying proportions of each material or any separately.
In order to deodorize, absorb, and utilize urine I apply and use fine coal ashes,
which are sifted and powdered or made fine by any convenient means. I propose to
use about nine pounds of the coal ashes to one gallon of urine. The ashes thus
prepared are placed in any suitable receptacle for containing the urine, and when
the ashes are completely saturated the contents of the receptacles can be removed,
and can be used as a valuable manure.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Hanson in the Great Seal Patent Office on the 22nd June 1876.
JOHN HANSON, of Savile Town, near Dewsbury, in the County of York, Manu-
facturing Chemist. " IMPROVEMENTS IN TREATING SEWAGE AND OTHER FOUL
WATER, AND IN DEODORIZING AND UTILIZING URINE TO BE USED FOR MANURE."
This Invention relates to certain improvements in the method or process of
treating (by precipitation) sewage and other foul water, such as that from dye, tan,
or other similar works or places, and it comprises an improved method or means of
deodorizing and utilizing urine for manure, the first portion of the improvements
having connection with the Invention of "Improvements in the Treatment of
Sewage and in the Manufacture of Manure therefrom," for which Letters Patent
were granted to me bearing date the 28th day of July 1875, No. 2675.
In carrying out my present Invention in order to clarify, precipitate, or make
colourless sewage, dye, tan, or other coloured or foul water, I treat the same with
slag, dross, or scoria from blast or metal smelting furnaces, and with chalk or whiting
commonly called "Paris white." These materials I use separately or in combina-
tion with any or all of the materials described in the Specification of my above
referred to Letters Patent (for effecting the precipitation of the sludge), previously
grinding or powdering and sifting them by any convenient means. In using these
materials I first thoroughly intermix them in their powdered state, and with the
addition of water, and then mix them with the sewage or other foul water (with or
without the addition of a suitable quantity of sulphuric acid or muriatic acid),
which is then either pumped or allowed to run into a settling tank or tanks for
precipitation, which completes the clarifying process. Valuable manure may then
be made from the precipitate thus obtained by the method or process described in
my above referred to Letters Patent.
As sewage or other foul water varies considerably in impurity, varying propor-
tions of the precipitating materials are required to be used. Amongst other formula
I use the following:-For each twelve millions of gallons of the sewage or foul
water I use (1) about seven tons of the slag, dross, or scoria, and about seven tons of
the black ash (otherwise known as black ash refuse), and about six tons of the
slacked lime; both of the latter as included under my said previous Patent; or (2),
about 6 tons of lime, about seven tons of black ash, and about seven tons of chalk
or whiting; or (3), about sixteen tons of lime, and about three tons of black ash;
or (4), about seven tons of slag, dross, or scoria, about three tons of black ash, about
six tons of lime, and about four tons of chalk or whiting; or (5), about seven tons
of slag, dross, or scoria, about three tons of black ash, and about ten tons of lime;
or (6), about five tons of chalk or whiting, about three tons of black ash, and about
twelve tons of lime. To these formula I sometimes add about one ton of either black
ash refuse, or slag, dross, or scoria mixed with half a ton of either muriatic acid or
sulphuric acid of the strength of about 140 to 170 degrees Twaddle.
In order to deodorize, absorb, and utilize urine I treat the same with fine coal
ashes, powdered or made fine, and sifted by any convenient means. I use about
nine pounds of coal ashes to one gallon of urine, the ashes being placed in. any

:
Having now described the nature and object of my said Invention for "Improve-
ments in Treating Sewage and other Foul Water, and in Deodorizing and Utilizing
Urine to be used for Manure," together with the manner in which the same is to be
or may be performed or carried into practical effect, I would remark in conclusion
that I claim as my Invention,-
The application and use of slag, dross, or scoria from blast or metal smelting
furnaces, and chalk or whiting (commonly called "Paris white,") separately or in
combination with muriatic acid or sulphuric acid (of 140 to 170 degrees Twaddle),
and with any or all of the materials described in the Specification of my said former
Letters Patent, No. 2675/75 (for effecting the precipitation of the sludge) for the
purpose of clarifying, precipitating, and rendering colourless sewage, dye, tan, or
other coloured or foul water.
I also claim the use of fine prepared coal ashes for the purpose of deodorizing,
absorbing, and utilizing urine as manure.
In witness whereof, I, the said John Hanson, have hereunto set my hand
and seal, this Twentieth day of June, in the year of our Lord One thousand
eight hundred and seventy-six.
JOHN HANSON. (L.S.)
