PROVISIONAL SPECIFICATION
Improvements in Apparatus for the Disinfection of Sewage
I PATRICK O'DOWD of Mount Pleasant, Ballyglass, in the County of Mayo,
Ireland, Landed Proprietor and Farmer, do hereby declare the nature of this
invention to be as follows
My invention relates to improvements in apparatus for the disinfection of
sewage for the purpose of utilization as manure, and consists of an intercepting
tank or chamber of special construction and arrangement in which the sewage
matter to be utilised is disinfected and piec pitated by a chemical or other suitable
agent
The intercepting tank or chamber, which I propose to arrange in connection with
the ordinary house drains, is prefer bly constructed of galvanized cast iron, sheet-
metal, or for large systems, of stone or brick work
An inter-
The tank may be of any convement form and is divided internally by two
horizontal cieens or partitions consisting of layers of fine wire, arranged one
Upon
above and one below the connection with the house drain or sewage inlet
the lower screen I prefer to place a sheet or layer of course canvas
mediate chamber is thus formed in the tank to receive the sewage, and a suitable
precipitating agent being supplied to the upper and lower screened compartments,
the fluid percolates through the lower wire screen and becomes disinfected without
carrying away the composition, soil cr chemical agent contained within the
screen
A compartment at the bottom of the tank receives the fluid which has been
disinfected and a suitable outlet being provided in connection with the bottom
compartment the fluid matter flows away to the main sewer or other conduit
To facilitate the removal of the solid matter from the tank I may arrange for
the upper screen to be hinged at one side or to be otherwise detachably arranged,
and both screens may be made detachable or removable for the purposes of
cleansing and renewal when required

page_text: The intercepting tank or chamber which I propose to arrange in connection with
the ordinary house drains is preferably constructed of galvanized cast iron, sheet
metal, or for large systems of stone or brickwork
The tank may be of any convenient form and is divided internally by two
horizontal screens or partitions
In order that my invention may be the better understood reference is had to the
accompanying drawings upon which
-
Figure 1, is a vertical section of my improved apparatus
The intercepting tank A as shewn on Fig 1 may be of any convenient size and
form the horizontal screens or partitions B consisting of layers of fine wire
arranged one above the other and situated either both below the connections C with
the house drain as shewn on Figure 1, or one above and one below the connection
with the sewage inlet or house drain as shewn in dotted lines Upon each of these
screens B I prefer to place a sheet or layer of coarse canvas band a suitable
precipitating agent being supplied to the upper and lower screened compartments
the fluid percolates through the lower wire screen and becomes disinfected without
carrying away the composition, soil or chemical agent contained within the
screens B
I prefer to use peat charcoal and sulphate of non as the disinfecting agents, the
upper screen being supplied with a layer of sulphate of iron E covered with a
sufficient quantity of peat charcoal D and the lower shelf being filled entirely with
peat charcoal
After passing through the lower chamber the sewage is perfectly disinfected and
the charcoal D retains the solid matter
A compartment at the bottom of the tank A receives the fluid which has been
disinfected and a suitable outlet F being provided in connection with the bottom
compartment-the fluid matter flows away to the main sewer or other conduit
To facilitate the removal of the solid matter from the tank I may airange for
the upper screen to be hinged at one side or to be otherwise detachably arranged,
and both screens may be made detachable or removable for the purposes of cleansing
and renewal when required
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
-
1 A disinfecting apparatus or chamber for sewage comprising a tank A having
a hinged or removable cover-said tank being furnished with two or more fixed or
removable perforated partitions B and inlet and outlet branches, as described herein
and illustrated upou Figure 1 of the accompanying drawings
