We WILLIAM FREDERICK BARTON MASSEY-MAINWARING of No 30 Grosvenor
Place Hyde Park in the County of Middlesex Bachelor of Laws and JAMES
EDMUNDS of No 8 Grafton Street Piccadilly in the County of Middlesex Doctor of
Medicine Member of the Royal College of Physicians of London Medical Officer of
Health and Public Analyst for the District of Saint James Westminster do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN ARRANGEMENTS
FOR USE IN OXYGENATING WATER CONTAMINATED WITH ORGANIC MATTER" to be
as follows:-
Our invention relates to arrangements for use in oxygenating water contaminated
with organic matter such as water intended for the supply of towns for drinking
purposes and for domestic use and the effluent or supernatant water of sewage and
our said improvements consist essentially of provisions admitting of the descent
and subsequent ascent of the water to be treated and the supply of air to the water
at or near the part where it ceases to descend and begins to ascend.
According to one application of our said Invention we form a well of considerable
depth and divide it into two compartments by means of a vertical partition at the
lower part of which is an opening which forms a communication between the said
compartments and we arrange in the well a pipe connected with a suitable
apparatus for forcing air which pipe terminates at its free end in the lower part
of the well and we force air through the said pipe and cause the water to be
oxygenated to flow into the well on one side of the said partition. The water thus
flowing into the well passes through the opening in the said partition into the
other compartment and rises therein and flows off from the upper part thereof and
the air forced through the said pipe mingles with and is dissolved in the flowing
water as it passes through the lower part of the well and is retained in solution in
the said water until by the said water rising in the compartment on the exit side
of the said partition the pressure gradually diminishes and the residual air escapes
from the water.
According to another application of our said invention we construct a passage
or conduit of tubes so arranged as to cause the water to be treated to descend.
and afterwards to rise and flow off the lower part of which passage or conduit is

page_text: provided with means admitting of the discharge of air into the water at the said
part. In some cases we form the said passage or conduit of tortuous or zig-zag
form or of spiral form or of other form which will cause the flow of water through
the said passage or conduit to be retarded and thus prolong the period during
which the air is held in solution in the water.
The application of our Invention is not limited to the precise arrangements
herein before described as the improvements constituting our said Invention are
capable of application to or embodiment in arrangements or apparatus of other
form.

We WILLIAM FREDERICK BARTON MASSEY MAINWARING of N° 30 Grosvenor
Place Hyde Park in the County of. Middlesex Bachelor of Laws and JAMES
EDMUNDS of N° 8 Grafton Street Piccadilly in the County of Middlesex Doctor of
Medicine Member of the Royal College of Physicians of London Medical Officer of
Health and Public Analyst for the District of Saint James Westminster 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:-
Our invention relates to arrangements for use in oxygenating water contaminated
with organic matter such as water intended for the supply of towns for drinking
purposes and for domestic use and the effluent or supernatant water of sewage and
our said improvements consist essentially of provisions admitting of the descent
and subsequent ascent of the water to be treated and the supply of air to the water
at or near the part where it ceases to descend and begins to ascend.
According to one application of our said Invention we form a well of considerable
depth and divide it into two compartments by means of a vertical partition at the
lower part of which is an opening which forms a communication between the said
compartments and we arrange in the well a pipe connected with a suitable
apparatus for forcing air which pipe terminates at its free end in the lower part
of the well and we force air through the said pipe and cause the water to be
oxygenated to flow into the well on one side of the said partition. The water thus
Howing into the well passes through the opening in the said partition into the

page_text: other compartment and rises therein and flows off from the upper part thereof and
the air forced through the said pipe mingles with and is dissolved in the flowing
water as it passes through the lower part of the well and is retained in solution in
the said water until by the said water rising in the compartment on the exit side
of the said partition the pressure gradually diminishes and the residual air escapes
from the water.
Figure 1 of the accompanying drawings represents in vertical section an
arrangement of the kind herein before described. A is the well B is the vertical
partition by which the said well is divided into two compartments a¹, a³ and b¹ is
the opening in the partition B which opening forms the communication between
the said two compartments. C is the pipe through which air is forced into the
water in the well A by means of any suitable apparatus (not shown in the
drawings) the said pipe being provided at its end with a spreader c¹. D is a pipe
through which the water to be treated enters the well A and E is a pipe through
which the water passes from the well after treatment and by which it is conveyed
away as required. The course of the water passing through the well is indicated
by the arrows.
Instead of arranging the outlet c¹ of the air pipe C in the compartment a³ in
which the water descends it may be arranged in the lower part of the com-
partment a in which the water ascends.
According to another application of our said invention we construct a passage or
conduit of tubes so arranged as to cause the water to be treated to descend and
afterwards to rise and flow off the lower part of which passage or conduit is
provided with means admitting of the discharge of air into the water at the said
part. In some cases we form the said passage or conduit of tortuous or zig-zag
form or of spiral form or of other form which will cause the flow of water through
the said passage or conduit to be retarded and thus prolong the period during
which the air is held in solution in the water.
An arrangement in which the water to be treated is caused to pass through a
tortuous or zig-zag conduit formed of tubes is illustrated in elevation partly in
section in Figure 2 of the accompanying drawings and in plan in Figure 3.
Referring to the said Figures 2 and 3 F F are the zig-zag pipes arranged in a
pit G in which the said pipes are supported by any suitable means (not shown in
the drawings). The end f1 of the pipe F opens into a channel H communicating
with the source of supply of the water to be treated and the end f³ of the pipe F¹
is arranged over a conduit I into which the water passes from the said pipe F¹ after
treatment. F is a box or chamber with which the lower ends of the pipes F F¹
communicate and J is the pipe through which air is forced into the water passing
through the pipes F and F¹ and the box or chamber F. The said water passes
through the said pipes and box or chamber by gravity in the direction indicated
by the arrows in Figure 2. The said pipes may be provided with means for
obtaining access to their interiors at the lower part for cleaning when necessary.
Figure 4 of the accompanying drawings is an arrangement corresponding with
that illustrated in Figures 2 and 3 except in respect of the form of the conduits F
and F¹ which in the said Figure 4 consists of spiral coils of pipes. The parts of
the said Figure 4 are marked with letters and Figures of reference corresponding
with those in Figures 1, 2 and 3 and need no further description.
Instead of making the pipe or conduit F in which the water descends of tortuous
or zig zag form as shown it may be made straight.
We prefer to make the well A herein before described with reference to Figure 1
of such depth and the stacks of pipes F F¹ hereinbefore described with reference to
Figures 2. 3 and 4 of such height that the height of the column or columns of
water therein will be sufficient to produce considerable pressure at the lower part
say from about twenty pounds to the square inch upward. We however do not
limit ourselves to any particular depth or height or proportions of the parts of the
apparatus herein before described.

page_text: In order to provide against fracture of the pipes F F by the pressure of the
water within them the pit G in which they are arranged may be filled with
water.
The apparatus for forcing air into the water in the well A or the pipes F, F¹
may be a force pump or any other known form of forcing apparatus of sufficient
power.
The application of our Invention is not limited to the precise arrangements
herein before described as the improvements constituting our said Invention are
capable of application to or embodiment in arrangements or apparatus of other
form.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
"
First Arrangements for use in oxygenating water which admit of the con-
tinuous descent and subsequent ascent of a stream of the water to be treated and
of the introduction of air into the said water at or near the point where it ceases
to. descend and begins to ascend.

Secondly-The arrangement hereinbefore described with, reference to and
illustrated in Figure 1 of the accompanying drawings for use in oxygenating
water.
Thirdly The arrangement herein before described with reference to and illus-
trated in Figures 2 and 3 of the accompanying drawings for use in oxygenating
water.
Fourthly The arrangement herein before described with reference to and illus-
trated in Figure.4 of the accompanying drawings for use in oxygenating water.
