IN THE PROCESS OF AND COMBINATION OF MATERIALS FOR THE PURIFICATION AND
DEODORIZATION OF SEWERAGE AND OTHER SIMILARLY POLLUTED MATTER AND TO
RENDER THE SAME MORE VALUABLE FOR MANURIAL PURPOSES
"
The object of this Invention is the more perfect and effectual purification and
deodorization of sewerage and other similarly polluted matter in an easy and less
expensive manner than hitherto performed
In carrying our Invention into practical effect we proceed as follows :—
The impure or polluted matter on being received from the sewer or other place
passes into a receptacle and is vigorously agitated by any known means and
simultaneously with the agitation we cause streams of Hydrochloric Acid and a
solution of Alkaline Soda to be injected into the matter requiring purification.
The effect of these chemicals meeting in the Company of the sewerage or other
matter causes Chlorine Gas to be evolved thereby destroying all sulphurretted

carbonaceous particles
The matter thus treated is then caused to flow into another receptacle or reservoir
and a solution of Sulphate of Iron is introduced which combining with the neutral
Salt (Chloride of Sodium) already produced by the chemical action in the "agitating"
receptacle hereinbefore described hastens the precipitation and renders perfect the
deodorization of all solid matter, preserving the ammoniacal and phosphatic salts,
thus increasing the fertilizing properties of the deposit and enhancing its value as
a manure

"
The object of this Invention is the more perfect and effectual purification and
deodorization of Sewerage and other similarly polluted matter in an easy and far
less expensive manner than hitherto performed
In carrying our Invention into practical effect we proceed as follows: the impure
or polluted matter on being received from the Sewers or other places passes into an
Agitator and simultaneously with the agitation we cause streams of Hydrochloric
Acid and a solution of Alkaline Soda to be injected into the matter requiring
purification The effect of these chemicals meeting in company with the Sewerage
or other matter causes Chlorine Gas to be evolved thereby destroying all impure
gases and at the same time Oxygenating all carbonaceous particles
The matter thus treated is caused to flow by means of a Channel into a receptacle
or Reservoir at the entrance of which a solution of Sulphate of Iron is introduced
which combining with the neutral Salt (Chloride of Sodium) already produced by
the chemical action in the agitating receptacle herein before described hastens the
precipitation and renders perfect the deodorization of all solid matter preserving
therein the ammoniacal and phosphatic salts thus increasing the fertilizing
properties of the deposit and enhancing its value as a manure.
The proportions of these Chemicals hereinbefore mentioned in relation to each
other are as follows:-
1st Hydrochloric Acid.
35 parts
2nd Crude Alkaline Soda by weight 55
3rd Sulphate of Iron

It is obvious that the process and proportions of the materials employed may be
varied as the carrying the Invention into practical effect may require as for instance
Sewerage containing the output from Chemical Manufactories Tanneries Gas Dye
and other works at times would require the addition in minute quantities of Clay
Coal dust or Ground Clinkers and occasionally the addition of either Lime or
Charcoal or Sulphuric Acid according to the various circumstances of each
individual case
We claim, the above process with the combined application therein of the
aforesaid materials all substantially as described.
In witness whereof we the said George James Andrews and Frank Hermitage
Parker have hereunto set our hands and seals the Nineteenth day of
September in the year of our Lord One thousand eight hundred and eighty
