PROVISIONAL SPECIFICATION.
Improvements in the Treatment for the Purification of Sewage of all
Kinds, Domestic or otherwise, including Effluents from Dye-
works and the like.
GEORGE DRAKE WILD, Hunsworth House, Cleckheaton, Yorks., Dyer, do hereby
declare the nature of this invention to be as follows;-
-
I collect the raw sewage into a tank, and with a powerful air pump I force
atmospheric air or gas into it to keep it in a state of violent agitation for a period
according to the nature of the sewage. I then put in lime or other precipitant and
agitate it again in the same manner after which it is ready. The whole is
pumped, syphoned, or run off into settling tanks. After settling, the clear liquor
is then allowed to run off. By repeating this operation according to the nature
of the sewage, an almost perfectly clear effluent can be produced.

Improvements in the Treatment for the Purification of Sewage of all
Kinds, Domestic or otherwise, including Effluents from Dye-
works and the like.
I, GEORGE DRAKE WILD, late of Hunsworth House, Cleckheaton, but now of
16, Edmund Street, Horton Lane, Bradford, in the County of York, Dyers Manager,
do hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, that is to say:-
It relates to improvements in the method of treating sewage whereby better
and more desirable results are obtained and with less outlay and expenditure of
labour than are incurred by following the method heretofore practised.
In carrying my invention into effect I make use of the devices illustrated by
the accompanying sheet of drawings in which;-
Fig. 1 is a view of a tank as seen from above.
Figs. 2 and 3 are sectional side and end elevations respectively of said tank.
Fig. 4 is a sectional end view (enlarged scale) of a pipe constructed as herein-
after described.
The sewage to be treated is conducted into a tank, as that at a, wherein the
pipes (which are preferably made of porcelain or like material to prevent
corrosion) are mounted as shown, said pipes 6 having lateral openings c made

page_text: in them preferably in the relative positions shown by Fig. 4, while the outer
end d of same is closed.
On the sewage being collected within the tank a I force a powerful current of
atmospheric air or gas into it thus causing it to be violently agitated and thoroughly
intermixed or impregnated with said air and this action I continue for a longer
or shorter period as the nature of the sewage may require.
After thus treating the sewage for a desired period of time (say from twenty
to forty minutes) I then add thereto a suitable precipitant, such as unslaked lime,
and after this I again subject the sewage to the agitating and other actions of the
air being forced into it, on which the whole liquid mass is allowed to flow from
the tank a (as by raising the hinged door f into the position shown in broken
lines Fig. 2) into either tanks or holders where it is allowed to remain until the
solid matter has precipitated to the bottom of such tanks. (Or it may be allowed
to flow directly on to the land where it is allowed thus to precipitate.) The
clear liquid above being drawn or allowed to flow away leaving the refuse with,
the precipitant to be afterwards treated by any of the well known processes.
The openings c are made in the pipes b in the positions shown by Fig. 4, so
as to direct the currents of air downward thus enabling same better to agitate the
sewage within the tank a and also avoid choking of the pipes b.
Having now particularly described and ascertained the nature and object of my
said invention, and in what manner the same is to be performed, I declare that what
I claim is:
The treatment of sewage by subjecting same to the agitating and other actions
of air then adding a precipitant thereto and afterwards again subjecting said
sewage to similar actions of said air substantially as herein specified.
Dated this 7th day of April 1899.
