Abstract
A sorptive-filtration system for removing at least one of negatively or positively charged ions, complexes or particulates from an aqueous stream. The system includes a) flow formed substantially from at least one of rainfall-runoff or snowmelt-runoff; b) a filter containment communicating with the runoff stream such that at least part of the stream passes through the filter containment; and c) a granular filter media disposed within the filter containment, the filter media having an amphoteric material applied thereto, wherein the amphoteric material comprises a metal selected from at least one of Fe, Al, Mn, or Si.
Claims32
A filtration system for removing waterborne constituents, comprising:
- a. an inflow conduit positioned to receive water runoff from a paved surface;
- b. a filter containment communicating with said inflow conduit such that at least part of said water runoff passes through said filter containment;
- and
- c. a granular filter media disposed within said filter containment, said filter media comprising an amphoteric material applied thereto, wherein said amphoteric material comprises at least one of aluminum oxide or manganese oxide, and wherein said filter media has a specific surface area of at least 20 m2/gram.
A filtration system for removing waterborne constituents from water runoff, comprising:
- a. a flow comprising water runoff from a paved surface;
- b. a filter containment communicating with said flow such that at least part of said flow passes through said filter containment;
- and
- c. a cementitious granular filter media disposed within said filter containment, said filter media comprising an amphoteric material applied thereto, wherein said amphoteric material comprises at least one oxide of a metal selected from at least one of Fe, Al, Mn, or Si.
A filtration system for removing waterborne constituents, comprising:
- a. a flow comprising water runoff from a substantially impermeable surface;
- b. a filter containment communicating with said flow such that at least part of said flow passes through said filter containment;
- and
- c. a granular filter media disposed within said filter containment, said filter media comprising an amphoteric material applied thereto, wherein said amphoteric material comprises at least one of aluminum oxide or manganese oxide.
A filtration system for removing waterborne constituents, comprising:
- a. a rigid media housing;
- b. a filter containment comprising a porous mesh material positioned in said media housing;
- and
- c. a granular filter media disposed within said filter containment, said filter media comprising an amphoteric material applied thereto, wherein said amphoteric material comprises at least one of aluminum oxide or manganese oxide.
A filtration system for removing waterborne constituents, comprising:
- a. an inflow conduit positioned to receive water from a unit operation and process system;
- b. a filter containment communicating with said inflow conduit such that at least part of said water runoff passes through said filter containment;
- and
- c. a granular filter media disposed within said filter containment, said filter media comprising an amphoteric material applied thereto, wherein said amphoteric material comprises at least one of an aluminum oxide, an iron oxide, a manganese oxide or silica, and wherein said filter media has a specific surface area of at least 20 m2/gram.
