Low profile catch basin filter
View Patent ↗A catch basin configured to filter water by way of a matrix filter and a filter pouch. If the matrix filter should become clogged, a bypass weir provides means of bypassing the matrix filter to prevent the catch basin from clogging.
1. A catch basin filter, comprising:
(a) a filter, wherein said filter comprises a textile surrounding a rigid skeleton;
(b) an inlet flume positioned upstream of said filter and configured to direct fluid towards said filter;
(c) a pouch positioned downstream of said filter;
(d) an outlet positioned downstream of said pouch; and
(e) a bypass weir positioned downstream of said inlet flume, said bypass weir substantially surrounding said filter and positioned along the bottom of the basin wall and configured to direct fluid passing through said weir to said outlet.
2. The catch basin filter of claim 1 , wherein said textile is polypropylene monofilament geotextile fabric.
3. The catch basin filter of claim 1 , wherein said rigid skeleton is formed of polypropylene.
4. The catch basin filter of claim 1 , wherein said pouch includes an absorbent material capable of collecting and retaining hydrocarbons.
5. The catch basin filter of claim 4 , wherein said pouch includes fossil rock.
6. A catch basin filter wherein said filter comprising:
a) a first flow route comprising:
i) a filter, wherein said filter comprises a textile surrounding a rigid skeleton;
ii) an inlet flume positioned upstream of said filter and configured to direct fluid towards said filter;
iii) a pouch positioned downstream of said filter; and
iv) an outlet positioned downstream of said pouch; and
b) a second flow path comprising:
i) an inlet flume; and
ii) a bypass weir positioned downstream of said inlet flume, said bypass weir substantially surrounding said filter and positioned along the bottom of the catch basin wall and configured to direct fluid passing through said weir to said outlet.
7. The catch basin filter of claim 6 , wherein said filter comprises a textile surrounding a rigid skeleton.
8. The catch basin filter of claim 7 , wherein said textile is polypropylene monofilament geotextile fabric.
9. The catch basin filter of claim 7 , wherein said rigid skeleton is formed of polypropylene.
10. The catch basin filter of claim 6 , wherein said pouch comprises an absorbent material capable of collecting and retaining hydrocarbons.
11. The catch basin filter of claim 6 , wherein said pouch includes fossil rock.
