PROVISIONAL SPECIFICATION.
Improvements in the Treatment of Sewage or analogous Foul
Waters or Matters for Effecting the Disinfection and Purification
thereof.
I ARTHUR PEACH HOPE of Imperial Buildings, Leicester, Analytical Chemist
do hereby declare the nature of my invention to be as follows:-
The principal object of my invention is to provide means by which sewage or
like foul waters or matters can be disinfected and purified efficiently and where
desired continuously.
According to my invention I forcibly inject air or oxygen into the sewage. This
injection can be effected by means of steam and there may also be used with the
said steam and air antiseptics disinfectants or deodorisers such as cresilic, cresotic,
carbolic or creosote emulsion or an emulsion of two or more of them combined or
the chemical equivalents thereof.
The injection of the air or oxygen by means of steam in conjunction with the
antiseptic disinfecting or deodorising medium if so desired can be effected by means
of injecting apparatus wherein the forcible passage of steam induces a current of
air which passes with the steam and with the antiseptic disinfectant or deodoriser
when such is used into the sewage or the like preferably through perforated pipes
which distribute the steam and air and antiseptic disinfectant or deodoriser (if such
be used) throughout the mass of sewage or the like passing thereover or in proximity
thereto. After the sewage or the like has been treated in this way it may have
applied to it any suitable or ordinary precipitant and thereafter the effluent water
and the precipitated solid matters may be collected in any suitable manner.

COMPLETE SPECIFICATION.
Improvements in the Treatment of Sewage or analogous Foul
Waters or Matters for Effecting the Disinfection and Purification
thereof.
I, ARTHUR PEACH HOPE of Imperial Buildings, Leicester, Analytical Chemist
do hereby declare the nature of my invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
The principal object of my invention is to provide means by which sewage or
like foul waters or matters can be disinfected and purified efficiently and where
desired continuously. According to my invention I forcibly inject air or oxygen
into the sewage by means of steam there being used with the said steam or steam
and air, antiseptics, disinfectants, deodorizers, germicides or oxygenating agents
such as crecylic acid, creasotic acid (wood creasote) carbolic acid or coal tar
creasote which for instance may be in the form of crude tar creasote known as
black carbolic acid or an emulsion of one or two or more of the said antiseptics,
disinfectants, deodorizers or germicides or the chemical equivalents thereof. The
emulsion may be made by means of soap in the usual way of making emulsions.

page_text: The injection of the air or oxygen by means of steam in conjunction with the
antiseptic or like medium can be effected by means of injecting apparatus wherein
the forcible passage of the said steam induces a current of air which passes with
the said steam and with the antiseptic or the like into the sewage or the like
preferably through perforated pipes which distribute the steam and antiseptic or
the like and air throughout the mass of sewage or the like passing thereover or in
proximity thereto. For example the sewage may be run into a vessel or channel
with openings in its bottom or side over each of which is situated a nozzle for the
admission of steam in conjunction with the antiseptic or the like selected, this
nozzle being surrounded by a casing through which air or oxygen is drawn by the
steam.
If the steam nozzle be narrowed and then again splayed out at the end and
caused to discharge into openings of a double cone form in the bottom or side of
the vessel or channel a very efficient action of the air steam and antiseptic or the
like is produced. The antiseptic or the like employed may be in the crude form
or in any other desired form such as an emulsion for instance and it may be placed
with the water in the boiler and carried over with the steam supplied to the
nozzles or the antiseptic or the like may be placed in a vessel or pipe distinct from
the boiler through which box or pipe steam passes on its way from the boiler to
the sewage or noxious matter or the steam and antiseptic or the like may be injected
together in any other convenient way. The currents of the said steam and air as
they pass from the nozzles act upon the sewage which passes through the holes in
the bottom or side of the vessel or channel in a very efficient manner. After the
sewage or the like has been treated in this way it may have applied to it any
suitable or ordinary precipitant and thereafter the effluent water and the precipitated
solid matters may be collected in any suitable manner.
The invention may be applied to the disinfection of other foul matters such for
instance as to the disinfection of clothes or rags.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The treatment of sewage or analogous foul waters or matters by the injection
of air or oxygen in combination with steam and an antiseptic disinfectant or
deodorizer substantially as and for the purposes hereinbefore described.
2. The treatinent of sewage or analogous foul waters or foul matters by firstly
treating it or them as set forth in the preceding claiming clause and subsequently
subjecting it to precipitation substantially as and for the purposes hereinbefore
described.
