I, JOHN HANSON, of Wakefield, in the County of York, Manufacturing Chemist.
and Sewage Engineer, do hereby declare the nature of said Invention for "IMPROVE-
MENTS IN THE TREATMENT OF SEWAGE OR FOUL WATERS OR OTHER SOLID
LIQUID IMPURITIES OR FOUL MATTERS FOR THE PURPOSE OF DEODORIZING
SAME AND FOR THE PREVENTION OF THE FORMATION OF SEWER, GAS" to 1

My Invention consists in effecting the deodorizing of sewage or foul waters or
other solid and liquid impurities or foul matters by the employment of what is
known as Black Ash Waste. a bye product from alkali works which may be
practically effected as follows:-
Into a suitable receptacle I place a quantity of Black Ash Waste, and fill up
with sewage, foul or other water or liquid and I thoroughly incorporate or mix
the whole and afterwards add the same or a decoction thereof to the sewage or
other foul water, thus fixing the volatile vapours and rendering the sewage
or other foul water free from smell.
For deodorizing foul solid matters, or mixed solid and liquid matters I add
thereto quantities as required of the liquid above described. Or I may add the
crude Black Ash Waste itself to the said matters in proportion as required, with
the result that they are, completely deodorized and the smell is immediately
checked on account of all the vapours becoming fixed and they therefore cannot
afterwards decompose.
By applying the liquid from Black Ash Waste to the sewage of common sewers
the prevention of sewage gas will be effected, and little or no smell will be observed
from the drains.
In places where Black Ash Waste is plentiful there are often found pools of the
liquid or decoction which decoctions have been naturally made by the rains perco-
lating through the heaps of the Black Ash Waste. This naturally made liquid is
equivalent to the liquid or decoction I above describe and therefore I may use it
for the purposes of my Invention.

I JOHN HANSON of Wakefield in the County of York Manufacturing Chemist
and Sewage Engineer do hereby declare the nature of my invention. for "IMPROVE-
MENTS IN THE TREATMENT OF SEWAGE OR FOUL WATERS OR OTHER SOLID AND
LIQUID IMPURITIES OR FOUL MATTERS FOR THE PURPOSE OF DEODORIZING THE
SAME AND FOR THE PREVENTION OF THE FORMATION OF SEWER GAS," and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My Invention consists in effecting the deodorizing of Sewage or foul waters or
other solid and liquid impurities or foul matters by the employment of what is
known as "black-ash waste" a lye product from alkali works which may be
practically effected as follows:-Into a cistern or receptacle of any suitablė
description I place a quantity of black ash waste and I put into or fill up the
said cistern or receptacle with Sewage or foul water or other water or liquid and
I thoroughly incorporate or mix. the whole and afterwards add the same (or a
decoction thereof after settlement) to the Sewage or foul waters to be treated
thus fixing the volatile matters or vapours and rendering the sewage or foul
waters free from offensive odour.
In preparing the aforesaid liquid or decoction I find good results are obtained if
I add to every 100 Gallons of water about 28lbs of Black ash waste.
For deodorizing foul solid matters or mixed solid and liquid matters I add
thereto quantities as required of the liquid prepared from Black ash waste as
above described or I may add the crude black ash waste itself to the said matters
in proportion as required with the result that they are completely deodorized
and any offensive odour is immediately checked on account of all the vapours
or vapourizable matters becoming fixed and they therefore cannot afterwards
decompose. By applying the liquid from black ash waste to the Sewage of
common Sewers the prevention of Sewage Gas will be effected and little or
no offensive odour will be observable from the drains.
In places where black ash waste is deposited there are often found pools of the
required liquid the decoction having been naturally made by the rain percolating
through the heaps of black ash waste. This naturally made liquid is of course.
equivalent to the liquid or decoction artificially prepared as herein before described
and therefore I may use it for the purposes of my Invention.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
The treatment of solid and liquid impurities or foul matters with black ash
waste or a liquor or decoction resulting or prepared therefrom substantially as
and for the purposes hereinbefore described.
