Complete Specification Left, 21st Mar., 1894-Accepted, 5th May, 1894
PROVISIONAL SPECIFICATION.
An Improved System for the Purification and Filtration of Sewage,
Foul Water from Sewers, Manufactories, and other Sources.
I, GEORGE BELL SHARPLES, of Victoria Buildings, Manchester, in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
=
The object of my invention is the purification of sewage, foul water from
sewers, manufactories or other sources, by a combined system of precipitation and
filtration.
I accomplish this by forming a series of precipitation tanks of the requisite
area, on the continuous flow principle, and placing at the overflow side of as many
of the tanks, as necessary, a platform of perforated slabs of concrete or other
suitable material, through which the water rises to overflow into the next tank.
Upon the platform of slabs is placed, and secured in a suitable manner, suitable
filtering media, and if necessary suitable chemicals, through which the water must
pass to the next tank.
I preferably form a double series of tanks, so that one may be cleansed while the
other is working if necessary, and also furnish suitable valves, pipes, sludge pits,
and other necessary apparatus for the convenient working of the system.
Dated this 21st day of June 1893.

COMPLETE SPECIFICATION.
An Improved System for the Purification and Filtration of Sewage,
Foul Water from Sewers, Manufactories, and other Sources.
I, GEORGE BELL SHARPLES, of Victoria Buildings, Manchester, in the County
of Lancaster, Engineer, 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 the purification of sewage, foul water from
sewers, manufactories, or other sources, by a combined system of precipitation and
filtration.
I accomplish this by forming a series of precipitation tanks of the requisite
area on the continuous flow principle and placing at the overflow sides of as many
of the tanks as necessary a platform of perforated slabs of concrete or other
suitable material through which the water passes to overflow into the next tank.
Upon the platform of perforated slabs is placed, and secured if necessary in a
suitable manner, suitable filtering media, and when necessary suitable chemicals,
through which the water must pass to the next tank.
By suitable divisions across the tanks the water can be made to pass upwards
or downwards, as may be best, through the filtering media &c. or both methods
may when advisable be combined in one system.
preferably form the first tank in duplicate so that one may be cleansed while
the other is working if necessary, and also furnish suitable valves, pipes, sludge
pits, and other necessary apparatus for the convenient working of the system.

page_text: Referring to the drawings sent herewith, Fig. 1 is a section, and Fig. 2. a
plan of a system of tanks and filtering media constructed according to my
invention.
a, indicates the inlet pipe, which conducts the impure water into the 1st tank b
whence after passing round washboard 62, as indicated by arrows, it passes over
partition 63 into the 2nd tank c, it then passes over partition c2, into 3rd tank d
then over partition d 2 and rises up through perforated slabs e and filtering
media and over partition d 3 into 4th tank g, whence it falls over partition g2
and downwards through filtering media fand perforated slabs e rising over
partition g 3 into effluent conduit the 4th tank g forming the final tank of this
series.
The tanks are provided with float pipes which by means of pipes i 2 enable the
surface water to be drawn off from any tank as required. Sludge pipes k are also
provided if necessary for conveying the sludge into sludge pit 7 whence it is
removed in the usual way.
By means of sluice door m, moveable washboards 62 and c 2 and moveable
partitions 64 and 65 the flow of water can be reversed through the first two tanks
or run through one of the tanks while the other is be cleansed.
By moveable partitions the flow can be regulated to rise or fall through the
filters as desired.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1st. The combination with a system of continuous flow precipitation tanks, of
suitable perforated slabs carrying suitable filtering media or chemicals, or both,
substantially as described and shown hereinbefore, and in the accompanying
drawings, for the purpose set forth.
2nd. The combined system of continuous flow precipitation tanks and perforated
slabs carrying filtering media, or chemicals, or both, as described and shown
herein before and in the accompanying drawings for the purpose set forth.
