Sewage, Drainage, and the like Matters:
1 JOSEPH FENTON of Cross Bank, Batley, in the county of York, Accountant, do
hereby declare the nature of Invention to be as follows:-
The object of my invention is by a simple and inexpensive means to rapidly purify,
filter and precipitate sewage, drainage and the like matters.
I employ a box containing alum through which the sewage or drainage passes, and
then to a tank in which are a series of strainers, these strainers are inexpensive and
easily removed and renewed, the liquid then passes away in a purified state.

Sewage, Drainage, and the like Matters.
I JOSEPH FENTON of Cross Bank, Batley, in the county of York, Accountant, 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:-
The object of my invention is by a simple and inexpensive means to rapidly purify,
filter, and precipitate sewage, drainage, and the like matters.

page_text: I employ a box or tank containing alum through which the sewage or drainage
passes, on its way to a tank or series of tanks in which are a series of strainers, these
strainers are composed preferably of straw or reeds, but may be made of other suitable
fibrous material so that they are inexpensive and easily removed and renewed, the
liquid then passes away in a purified state.
DESCRIPTION OF DRAWINGS.
Fig. 1 shows a cross sectional elevation of my filter tanks, on the line A. B of
Fig. 2.
Fig. 2 is a plan of my improved filtering system.
Fig. 3 is a longitudinal elevation of Fig. 2 on the line C. D.
E is the box of tank containing alum or its equivalent, through which the sewage
or drainage passes on its way to the tanks F, F, and F, of which there may be any
number according to the amount of sewage to be treated, is the inlet, and H the
outlet, these tanks are divided at intervals by division walls J, having openings J at
their bottoms, and strainers K placed in the upper parts of these division walls, through
which the liquid passes, the tanks are preferably formed with a rising bottom I from
the inlets to the outlets, the outlets M for the sediment being under or near the inlets G,
by this arrangement as the sewage passes through the box or tank E containing aluni
or its equivalent, it is deorderized, disinfected, and precipitated, the top or purer
portion of the liquid then passes to the tanks and through the first screens or strainers,
and then through the next, and so on, according to the amount of filtering required,
and the amount of sewage to be treated, the sludge or dense matter precipitated is
taken out at the outlets M. near or under the inlets, the sloping bottom L, assisting it
to the sludge outlets M.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The treatment of sewage by passing it through a tank containing alum or its
equivalent, and then to a series of tanks and strainers for the purposes shewn and
described.
2. The general arrangement of tanks as shewn and described.
