I GEORGE HENRY LEANE 21 Queen Annes Gate in the city of Westminister Civil
Engineer do hereby declare the nature of my invention for AN IMPROVED METHOD
OF CONTINUOUS FILTRATION APPLICABLE TO THE PURIFICATION OF SEWAGE, AND
FOR OTHER PURPOSES, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My Invention relates to an improved method of continuous filtration, and is
specially applicable to the purification of sewage and sewage water, and all cases
in which large volumes of foul fluids are required to be purified, and freed from
organic, or other suspended matter, as well as matter held in solution.
I carry out my invention in the following manner, which will be readily
understood by reference to the drawing, in which,
Fig. 1 is a plan of the filter.
Fig. 2 a section of part of same to enlarged scale upon line A B.
Fig. 3 one of the filter plates.
In any convenient position, I construct a tank of rectangular, or other suitable
shape, see Figs. 1 & 2, in which A, is the outer, or boundary wall. This tank is
divided at any suitable point by a partition B, which with the wall A forms the
inlet C, by which the sewage, or other fluid enters. The partition B, has a series
of ports, or sluices D, through which the sewage or fluid enters to the depositing
chambers E. In the drawing three of these chambers are shewn ; but any required
number may be employed, depending upon the volume of fluid to be defecated, or
purified.
Within the depositing chambers, and between the ports D, in each division B¹,
are placed the perforated plates F F; see also Fig. 3, these may be made of wood,
zinc, iron, stone, perforated brick, or tiles, or any other substance suited to the
purpose. Between each set of plates F F, F F, a channel G, is formed which
receives the filtered fluid and forms the outlet for it. The bottom of the chamber G
which is supported at intervals upon supports K K, may also be of similar
construction with the sides thereof, so as to admit of upward filtration, thus
increasing the filter area, without increasing the size of the tank. The space H,
between the filter plates F F, is filled with a special form of carbon; obtained as a
residual product from the distillation of Kimmeridge shale, after the oil, and other
ונם...מ

I find this form of carbon specially active in deoderising and defecating, or
purifying, all forms of impure fluids; and when spent, and mixed with the
deposited foecal, or other matter in the chambers E, it forms an exceedingly rich
fertilizer, the ammonia and other fertilizing ingredients contained in the fluid
being fixed, or retained by it. If desired the carbon can be cleansed by burning,
and used again.
The water, or fluid to be filtered, flows in the direction shewn by the arrows,
depositing its solid matter in the chambers E, and passing away purified by the
channels G. The solid matters remaining in the chamber E, can be pressed, & dried,
or treated in any way which may be desired.
I have now described my invention, and wish it to be understood that in con-
structing my filter, and in the application and use of the carbon medium for the
purposes set forth, I do not bind myself to the exact details shewn, and described,
since these may be varied to suit circumstances without in any way departing
from its nature or intent. I lay no claim to the forms of carbon, or charcoal, now
in use for purposes of filtration, but what I believe to be novel, and desire to
claim is
The general arrangement, combination, and method of continuous filtration
with the medium employed for the purification, defecation, or cleansing of sewage
and other foul fluids. The filtering medium being that form of carbon obtained
as a residual product in the distillation of Kimmeridge shale substantially as
shewn, and for the purposes described.
