Catch basin filter absorber apparatus for water decontamination

A filtration apparatus for mounting in an associated catch basin for receiving associated runoff water which comprises:

• a housing, said housing having a top and a bottom, said bottom having an outlet for discharging a liquid;
• at least a first suspension member having a first axial extremity for attaching to a wall of the associated catch basin and a second axial extremity for attaching to said housing;
• a filtration media disposed in said housing and disposed to cause liquid in said housing to pass through said filtration media before passing out of said outlet;
• said housing having an overflow that allows passage of liquid entering said housing, at a rate that is greater than a predetermined rate, to bypass said filtration media wherein said filtration media includes one or more absorbents, said apparatus further includes a deflector for directing associated runoff water into said housing and wherein said filtration media is disposed in a cartridge having a central bore.

A filtration apparatus for decontaminating runoff water from a plurality of catch basins which comprises:

• an interceptor tank to collect the runoff water;
• a containment tank for treatment of runoff water, a plurality of modular filter/absorber cartridge assemblies disposed in said containment tank;
• a float operated sump pump disposed in said interceptor tank for directing runoff water from said interceptor tank to said containment tank;
• and
• a drain conduit extending from said containment tank to discharge treated runoff water.

A filtration apparatus for mounting in an associated catch basin for receiving associated runoff water which comprises:

• a housing, said housing having an inside and an outside and a top and a bottom;
• an elongated perforate standpipe having an inside and an outside and a first axial extremity and a second axial extremity and a plurality of openings therein disposed along the axial extent, said standpipe being mounted in said housing with a fluid tight connection between the second axial extremity of said standpipe and said bottom of said housing with the interior of said standpipe in fluid communication with the outside of said housing and each of said plurality of openings therein disposed along the axial extent of said standpipe providing a plurality of fluid communication paths between said inside of said housing and said inside of said standpipe;
• a filtration media disposed in said housing proximate to an axial portion of said standpipe, said filtration media being dimensioned and configured to filter the associated runoff passing through said plurality of fluid communication paths
• said filtration media comprising a plurality of horizontally layered absorbent materials, each layer in the said plurality of horizontally layered materials having a unique composition, respective layers being disposed in aligned relationship with respective fluid communication paths whereby the filtration media characteristics at respective fluid communication paths will be different.
