Abstract
A unit cartridge with a support ring gasket, and upper debris sweep, and debris retention bin is presented for use in filtering storm water runoff. Unlike some other configurations of cartridges, which rest the bottom of the cartridge on a support grate and ring, the present configuration rests on a support ring formed or built to the top of the cartridge. A
debris bin is formed above and as part of the unit cartridges to capture sediment which would otherwise lie on top of the cartridges or filter baskets to prevent or impede removal. At the top of the cartridge is a debris sweep to remove adhering debris to allow easier installation and removal of the cartridge. Below the support ring may be formed or placed a gasket to prevent further debris or water bypass when the cartridge is seated. The cartridge is adapted to existing or new storm water or water infiltration wells which have been adapted to receive and support the cartridge filter. The cartridge can be fit into conventional storm water infiltration wells that are pre adapted to receive filters.

Description
REFERENCE TO A "SEQUENCE LISTING," A TABLE, OR A COMPUTER
PROGRAM LISTING APPENDIX SUBMITTED ON A COMPACT DISK
Not applicable TECHNICAL FIELD This invention relates to a cartridge filter with sweep used in storm and other water infiltration wells.
BACKGROUND OF THE INVENTION
In storm water diversion into recharge wells, filters are used to remove finer sediments and dissolved components of the water stream. The finer sediments are trapped in and on top of the filters. Experience shows the sediment layer can be substantial so that the sediment can form a friction layer against removal of the filters. The cartridge filter herein uses a sweep to reduce sediment, a debris or sediment capture barrel, and a gasket on a cable removable filter.
DISCLOSURE OF INVENTION
I have come to the realization that sediment can lead to maintenance issues by impeding removal of the filters below, and by falling into the well below the filters on removal could result in contaminated sediments being spilled into the bottom of the recharge well.
be a major impact on recharge wells, including filtered recharge wells. Many recharge wells without sweeps and debris barrels or debris removal mechanisms have to be redrilled periodically. Filtered wells need more frequent maintenance because of debris or sediment. A structure is provided herein for sweeping the sidewalls of the receiving well of debris, for providing a gasketed fitting to an existing or new receiving ring, and for capturing debris in a chamber above the media filters but not in the baxrel of the well above the filters. Once through the cartridge, the water is directly discharged into a recharge well or into further filtered recharge well.
A cartridge is disclosed herein which has a sweep to clean the wall of debris and sediment which would otherwise bind the cartridge by friction into the well wall. Further a gasket is disclosed to further prevent bypass and to provide more even seating of the cartridge. A cartridge is disclosed herein where there is a sediment or debris chamber above the filter media. A cartridge is disclosed herein where there are filter media below the debris chamber. A cartridge is disclosed herein where a filter separation layer rests on an integral (formed or mechanically fastened) grate being the bottom part of the cartridge.
Description CROSS-REFERENCES TO RELATED APPLICATIONS
Aquifer recharge techologies are becoming more common and more accepted and included unfiltered wells, unfiltered horizontal drains, vegetative strips, and infiltration ponds and galleries. A problem with these technologies is the accumulation of debris and sediment in the body of unfiltered wells, plugging of the formation around the well, or the plugging of upper surfaces of the soils by debris.
Further, there are sediment traps such as ponds which require large tracts of lands, horizontal pipes without filters, centrifugal sediment trapping technologies which fit in series with systems for recharge, and catchbasin inserts.
The structure disclosed herein can be used instead of or as an add on technology. For example when used instead of a sediment pond, a builder can use the land formerly set aside for ponds to build green space, more houses, and to protect the public from debris and flows.

BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is profile view of the cartridge filter.
FIG. 2 is a profile view of the cartridge filter in a new or existing adapted infiltration well.
FIG. 3 is plan view of top of the textile based debris trap.
DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, a cartridge for storm water is illustrated. The body of the cartridge is a pipe (1) of known strength and radius. The pipe (1) has an upper support ring (3) fastened to the top of the pipe by a glue or screws(2) or is made integral with the cartridge body (1). A cable (15) with connectors (16) is used to install and remove the cartridge. A sweep (14) is fastened to the top of the support ring (3). A
gasket (13) is below the support ring (3). A series of eye bolts (12) with nuts (11) through holes (4) in the wall of the pipe (1) are used to fasten the support cables (15). At the bottom of the cartridge is a support grate 6), on which rests a filter fabric (5) designed to retain the fines of the filter media (7). Above the filter media (7) are other media layers (8,9) (of which two are shown. Above the media is a sediment or debris chamber (21). A
sediment or debris catcher not shown herein may also be present.
Referring to Figure 2 one sees a complete cartridge (19) fit into an existing storm or other water recharge well (17). A support ring (18) is adapted to support the cartridge (19). The well may be slotted (20) and or open at the bottom.
Referring to FIG.3 one sees the a plan view. The sweep (14) is visible. Below the sweep (14) is shown the cartridge body (1). The eye bolt holes (4) are shown in the body of the cartridge (1). The top filter media (9) is shown looking at it from the top.
The filter connector screws (2) are shown. The support ring is shown (3).
The invention as shown herein Allows for the use of a cartridge filter with a sediment chamber, a debris sweep, a bottom grate and filter fabric to be placed in new or old adapted stormwater or other water charging or recharge wells. The cartridge rests on a support ring at its top, and has a gasket to provide for more secure seating.
A cable with connectors is able to remove the filter. The cartridge relys on the sweep and gasket, and not on filter cartridge expansion, as is the case of other filters, to prevent bypass.
Finally, the patent device is a patentable article, useful to commerce and the environment, and the process is patentable with the articles, and is useful to commerce.
