Aquarium filter media including nanofibers
View Patent ↗A filtration device for an aquarium comprising a filtering chamber for receiving water and a filter medium therein wherein said filter medium comprises fibers having a diameter from 0.1 nm to 3000 nm and an aspect ratio of length to diameter of 5:1 to 10,000 to 1 wherein said fibers provide for colonization of nitrosomonas bacterium and/or nitrobacteria.
1. A filtration device for an aquarium comprising:
a filtering chamber including a nanofiber filter media therein wherein said nanofiber filter media comprises random nanofibers having a diameter from 100 nm to 900 nm and an aspect ratio of length to diameter of at least 5:1 wherein said nanofibers contain nitrosomonas bacterium and/or nitrobacteria; and
wherein the nanofiber filter media does not include a support material.
2. The filtration device of claim 1 wherein 80% by weight of said nanofibers in said filtering chamber have a diameter of 200 nm to 800 nm.
3. The filtration device of claim 1 wherein said nanofibers have a surface area of 2.0 m 2 /gram to 10.0 m 2 /gram.
4. The filtration device of claim 1 wherein said nanofibers are in the form of a nonwoven fabric.
5. The filtration device of claim 1 wherein said nanofibers have a surface and said colonization of said nitrosomona bacteria and/or said nitrobacteria occurs on said surface of said nanofibers.
6. The filtration device of claim 5 wherein 50.0% or more by weight of said nitrosomona and/or said nitrobacteria occurs on said surface of said nanofibers.
7. The filtration device of claim 1 wherein said nanofibers are bonded together.
8. The filtration device of claim 1 further including at least one of the following: ceramic material, crushed coral or crushed clam shells.
9. The filtration device of claim 1 further including at least one of the following: activated charcoal, zeolite, foam or glass fiber.
10. Filter media of claim 1 wherein 80% by weight of said fibers have a diameter of 200 nm to 800 nm.
11. Filter media of claim 1 wherein said nanofibers have a surface area of 2.0 m 2 /gram to 10.0 m 2 /gram.
12. Filter media of claim 1 wherein said nanofibers are in the form of a nonwoven fabric.
13. Filter media of claim 1 wherein said nanofibers have a surface and said nitrosomona bacteria and/or said nitrobacteria are present on said surface of said nanofibers.
14. Filter media of claim 13 wherein 50.0% or more by weight of said nitrosomona and/or said nitrobacteria occurs on said surface of said nanofibers.
15. Filter media of claim 1 wherein said nanofibers are bonded together.
16. Filter media of claim 1 further including at least one of the following: ceramic material, crushed coral or crushed clam shells.
17. Filter media of claim 1 further including at least one of the following: activated charcoal, zeolite, foam or glass fiber.
18. Filter media comprising:
a nanofiber filter media comprising random nanofibers having a diameter from 100 nm to 900 nm and an aspect ratio of length to diameter of at least 5:1 wherein said nanofibers contain nitrosomonas bacterium and/or nitrobacteria; and
wherein the nanofiber filter media does not include a support material.
19. A method for filtering water in an aquarium comprising: supplying a nanofiber filter media wherein said nanofiber filter media comprises random nanofibers having a diameter from 100 nm to 900 nm and an aspect ratio of length to diameter of at least 5:1 wherein said nanofibers contain nitrosomonas bacterium and/or nitrobacteria and contacting said water with said nanofiber filter media, wherein the nanofiber filter media does not include a support material.
