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.
Claims29
A filtration system for removing waterborne constituents, comprising:
- a. a flow formed from water runoff;
- 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 oxide of a metal selected from at least one of Al, Mn, or Si.
A filtration system for removing waterborne constituents from water runoff, comprising:
- a. a flow formed substantially from water runoff;
- 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 oxide of a metal selected from at least one of Fe, Al, Mn, or Si;
- d. wherein said media is a granular media produced by a process comprising the steps of:
- i. providing a granular media having a specific gravity of between about 0.2 and about 1.0;
- ii. providing a wet cement mix comprising in part an amphoteric solution;
- iii. coating said media with said wet cement mix;
- and
- iv. hydrating or drying said wet cement mix on said substrate.
A filtration system for removing waterborne constituents, comprising:
- a. a flow formed substantially from water runoff;
- b. a filter containment communicating with said flow such that at least part of said flow passes through said filter containment;
- and
- c. a porous fixed matrix 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 formed substantially from at least one of rainfall-runoff or snowmelt-runoff;
- 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 a specific gravity of less than one and at least a partial cementitious coating having an amphoteric material applied thereto, wherein said amphoteric material comprises a metal selected from at least one of Fe, Al, Mn, or Si.
A filtration system for removing waterborne constituents, comprising:
- a. a flow formed from water runoff;
- 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 oxide of a metal selected from at least one of Al or Mn, and wherein said filter media has a specific surface area of at least 10 m2/gram.
