Prussia and German Empire for an Invention of AN IMPROVED PROCESS
FOR MANUFACTURING ARTIFICIAL DUNG AND SIMULTANEOUS PURIFICATION OF
SEWAGE WATER FROM FŒCAL MATTER AND ALSO IN THE PURIFICATION OF
ALL WASTE OR FOUL WATER PRODUCED BY CHEMICAL AND OTHER FACTORIES
PROVISIONAL SPECIFICATION left by the said Samuel Walter at the Oflice
of the Commissioners of Patents on the 6th November 1882.
SAMUEL WALTER of the City of Berlin in the Kingdom of Prussia and Gerinan
Empire. AN IMPROVED PROCESS FOR MANUFACTURING ARTIFICIAL DUNG AND
SIMULTANEOUS PURIFICATION OF SEWAGE WATER FROM FECAL MATTER AND ALSO
IN THE PURIFICATION OF ALL WASTE OR FOUL WATER PRODUCED BY CHEMICAL
AND OTHER FACTORIES.
My invention relates to an improved process for manufacturing artificial dung
and simultaneous purification of sewage water from foecal matter and also in the
purification of all waste or foul water produced by chemical and other factories.
The principal features of my said invention consists :-
Firstly therein that the solid matter is precipitated in exceedingly short time
from sewage of all descriptions it being immaterial from whence such sewage is
taken, from cesspools, the ordinary town sewage or from chemical or other factories
and that simultaneously with the precipitation of such said solid fecal matter all
inaterial which produces fermentation is eliminated.
Secondly theroin that the fluid containing foecal matter is so thoroughly purified
that the so purified water can be led off into any stream, river or otherwise
without producing any deleterious effects and can also be employed for drinking
and other purposes.
In respect to the first part of my said invention id est the precipitation of focal
matter from sewage and other water I carry out this said part of my invention in
the following manner.

page_text: Brine in which herrings or other sea fish have been salted, the salt remaining
as deposit in old herring casks, common sea silt or its equivalent is diluted with
lime water according to the matter contained in such said sowage, waste or foul
water.
This mixture of brine and lime water is added to the sewage or other water so
that the said fecal matter contained in the fluid is precipitated in from 5 hours to
3 days according to the size of the receptacle or basin and at the same time freed
from all matter tending to produce fermentation.
•
In order to thoroughly purify the remaining fluid from all light foecal stuff and
nauseous smell this said fluid is led off through a grating formed of thin moveable
rods which said rods are tapered to an edge at the lower side, into a receptacle
of zinc or other suitable material or the said grating can be replaced by a fine sieve
of suitable wire.
This said zinc receptaclo is provided with a perforated sliding or moveable false
bottom from whence the fluid escapes into a filtering basin filled with finely sifted
sand.
The fluid passes through the perforated bottom of this said filter filled with
finely sifted sand into a second filter filled with coke, sand or other suitable filtering
material and from this said filter into a third filter filled or partially filled with
wood or vegetable charcoal and passes off from this said third filter in a perfectly
lucid pure state so that the said water can be employed for drinking or other
domestic purposes or can be led into a river canal or other water course.
Between the said zinc receptacle or basin and between the remaining filters I
employ a space of about 0,5 to 3 Meters=194 inches to 10 feet filled with thorn
twigs or brush.
The precipitate obtained in the various receptacles is removed from the same,
placed in covered sheds and dried in the-air-or-by-means of suitable.steam_or_other
drying apparatus.
The so dried foecal matter is now pulverised in suitable mills and then passed
through sieves of various degrees of fineness.
The artificial dung so produced forms a valuable substitute for the expensive
guano.
The fluid passing off from the first operation can be employed as fluid dung or
can be purified in the manner as described above in this specification and employed
for general purposes or led off into public streams, canals or other water courses
Another advantage attained by my said process is that the spent sand in the filters
which said sand is intimately mixed with focal matter can be employed for
improving the growth of grass on meadows or pastures generally.
The coke and vegetable charcoal employed for such said filtering purposes the
pores of which are filled with the fatty parts of the foecal matters, possess increased
heating properties and are as such of greater value than previous to their
employment as filtering material.

the said Samuel Walter in the Great Scal Patent Offico on the 1st May
1883.
SAMUEL WALTER, of the City of Berlin, in the Kingdom of Prussia and German
Empire, "IMPROVED PROCESS FOR MANUFACTURING ARTIFICIAL DUNG AND
SIMULTANEOUS PURIFICATION OF SEWAGE WATER FROM FŒCAL MATTER, AND ALSO
IN THE PURIFICATION OF ALL WASTE OR FOUL WATER PRODUCED BY CHEMICAL
AND OTHER FACTORIES.'
"
My Invention relates to an improved process for manufacturing artificial dung
and simultaneous purification of sewage water from foecal matter and also in the
purification of all waste or foul water produced by chemical and other factories.
The principal features of my said invention consist;
Firstly therein that the solid matter is precipitated in exceedingly short time
from sewage of all descriptions it being immaterial from whence, such sowage is
taken, from cesspools, the ordinary town sewage or from chemical or other factories
and that simultaneously with the precipitation of such said solid foccal matter all
material which produces fermentation is eliminated.
Secondly therein that the fluid containing focal matter is so thoroughly purified
that the so purified water can be led into any stream, river or otherwise without
producing any deleterious effects and can also be employed for drinking and other
purposes.
In respect to the first part of my said invention id est the procipitation of focal
matter from sewage and other water I carry out this said part of my invention in
the following manner.
Brine in which herrings or other sea fish have been salted, the salt remaining as
deposit in old herring casks, common sea salt, or its equivalent is diluted with
lime water according to the matter contained in such said sewage, waste or foul
water.
This mixture of brine and lime water is added to the sewage or other water so
that the said fecal matter contained in the fluid is precipitated in from 5 hours to
3 days according to the size of the receptacle or basin and at the same time freed
from all matter tending to produce fermentation.
In order to thoroughly purify the remaining fluid from all light foecal stuff and
nauseous smell, this said fluid is led off through a grating formed of thin moveable
rods which said rods are tapered to an edge at the lower side, in a receptacle of
zine or other suitable material or the said grating can be replaced by a fine sieve
of suitable wire.
This said zinc receptacle is provided with a perforated sliding or moveable false
bottom from whence the fluid escapes into a filtering basin filled with finely sifted
sand.
The fluid passes through the perforated bottom of this said filter filled with finely
sifted sand into a second filter filled with coke, sand or other suitable filtering
material and from this said filter into a third filter filled or partially filled with
wood or vegetable charcoal and passes off from this said third filter in a perfectly
lucid pure state so that the said water can be employed for drinking or other
domestic purposes or cau be led into a river canal or other water course.
Between the said zinc-receptacle or basin and between the remaining filters I
employ a space of about 0,5 to 3 Meters-19 inches to 10 feet filled with thorn,
twigs or brush.
The precipitate obtained in the various receptacles is removed from the same,
placed in covered sheds and dried in the air or by means of suitable steam or other
drying apparatus.

page_text: The so dried foecal matter is now pulverised in suitable mills and then passed
through sieves of various degrees of fineness.
The artificial dung so produced forms a valuable substitute for the expensive
guano.
The fluid passing off from the fresh operation can be employed as fluid dung or
can be purified in the manner as described above in this specification and
employed for general purposes or led off into public streams, canals or other water
courses.
Another advantage attained by my said process is that the spent sand in the
filters, which said sand is intimately mixed with foccal matter, can be employed for
improving the growth of grass on meadows or pastures generally.
The coke and vegetable charcoal employed for such said filtering purposes, the
pores of which are filled with the fatty parts of the foecal matters, possess increased
heating properties and are as such of greater value than previous to their
employment as filtering material.
Having now described my said invention and the manner in which the same is
to or may be carried into effect I wish it to be understood that what I claim and
desire to secure by Letters Patent is :-
1. The employment of the process of precipitating foccal matter from sewage or
other foul and impure waters by adding herring brine or sea salt to the said waters
in-order-to be able to use the solid parts of the said fecal inatter (gained in the
further process of filtration) as dung or guano substantially as hereinbefore. set
forth.
2-The employment of the process of thoroughly purifying the fluid containing
foecal matter passing it through a grating into a receptacle with a perforated and
moveable bottom, then through bramble or brush in a filtering basin and from here
again over brush into a third receptacle whence at last passing through heaped up
charcoal, it can be led into any river, stream, lake or other water course_without
producing any deleterious effects substantially as hereinbefore set fortli.
In witness whereof I the said Samuel Walter have hereunto set my hand and
seal this twenty second day of February in the year of our Lord One
thousand eight hundred and eighty-three.
