The Treatment of Alkali Waste for Use in the Purification and
Deodorization of Sewage and Impure Waters or Matters.
J, JOHN HANSON of Wakefield in the County of York Manufacturing Chemist do
hereby declare the nature of this Invention to be as follows :-
The object of my Invention is to so treat alkali waste that it is rendered more suitable
for and effective in, the treatment of sewage and impure waters or matters for deodo-
rizing and purifying them than it would otherwise be. With this object submit the
alkali waste to intimate contact with oxygen which is effected by finely dividing or
grinding the alkali waste and submitting it in that state to the action of atmospheric
air. Or in place of or in addition to the oxidation I may subject the ground or finely
divided alkali waste to the action of sulphurous acid gas which I prefer to generate by
means of hydrochloric acid and partially oxidised alkali waste the gas formed by the
contact of these matters being led off and caused to enter into and amongst the finely
divided or ground alkali waste to be absorbed thereby.

Deodorization of Sewage and Impure Waters or Matters.
1 JOHN HANSON of. Wakefield in the County of York Manufacturing Chemist do
hereby declare the nature of this Invention and in what manner the same is to he
performed to be particularly described and ascertained in and by the following
statement that is to say :-
The object of my Invention is to so treat Alkali waste that it is rendered more
suitable for and effective in the treatment of Sewage and impure waters or matters
for deodorizing and purifying them than it would otherwise.be.
With this object I submit the Alkali waste to intimate contact with Oxygen which
is preferably effected by finely dividing or grinding the Alkali waste and submitting
it in that state to the action of atmospheric air.
In order to cause the air to act effectually on the Alkali waste the latter is preferably
finely riddled and allowed to fall through the air thus exposing all the fine particles of
waste to the action of the air and thereby causing them to be rapidly oxidized. The
Alkali waste may be placed in heaps exposed to the air which is allowed to penetrate
the bulk or mass or the Alkali waste may be spread in thin layers exposed to the air
which is mechanically forced through the powder or any other suitable means may be
employed for the same purpose namely oxidizing the waste-Or in place of or in
addition to the oxidation I may subject the ground or finely divided Alkali waste to
the action of Sulphurous Acid gas which I prefer to generate by means of hydrochloric
acid and partially oxidized Alkali waste the gas formed by the contact of these matters
being led off and caused to enter into and amongst the finely divided or ground Alkali
waste to be absorbed thereby.
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 :-
First. The treatment of Alkali waste for use in the purification and deodorization of
sewage and impure waters or matters by exposing the Alkali waste in a pulverized or
finely divided condition to the action of atmospheric air or oxygen substantially as
herein before described.
Second. The treatment of Alkali waste for use in the purification and deodorization
of Sewage and impure waters or matters by exposing the Alkali waste to the action of
Sulphurous Acid Gas generated by the action of Hydrochloric Acid on Alkali wasto
or otherwise substantially as herein before described.

of sewage and impure waters or matters by exposing the Alkali waste to the combined
action of atmospheric air or oxygen and Sulphurous Acid gas substantially as herein-
before described.
Fourth. The improved process for the treatment of Alkali waste as and for the
purpose herein before set forth.
