Abstract

A portable, personal apparatus for treating drinking water comprises a generally tubular or cylindrical filter housing containing filtration media and water-permeable screen or mesh or felt or membrane or netting layer at the top and bottom ends of the filter. The design of the apparatus involves the bottle exterior and interior contouring to the filter and enables the efficient and rapid gravity flow of water in through the filter. The apparatus may be configured such that water is first passed through a top reservoir designed to receive water, followed by a porous mesh, followed by granular filtration and antimicrobial media agitated by turbulent motion of influent water, followed by a porous mesh before reaching a durable and reusable water containment vessel.

Claims

1. A portable, personal apparatus for treating drinking water, comprising:

a generally tubular or cylindrical filter housing having a filter containing filtration media that comprises a water-permeable screen or mesh or felt or membrane or netting layer at the top and bottom ends of the filter enabling gravity flow of water through the filter.

2. The apparatus of claim 1, wherein said filter allows for bidirectional flow.

3. The apparatus of claim 1, wherein said filter allows for a bottle fill rate of 0.5 Lpm to 5 Lpm through the filter cartridge.

4. The apparatus of claim 1, wherein the apparatus includes a reservoir at the top entrance of the filter to temporarily hold and funnel influent water into the filter.

5. The apparatus of claim 1 further comprising a cap configured to be placed on top of the filter to prevent water from escaping the unit when sealed.

6. The apparatus of claim 5, wherein said cap is sealable to the filter.

7. The apparatus of claim 1 further comprising a portable, personal, reusable bottle body serving as a vessel upon which said filter housing is attached.

8. The apparatus of claim 7, wherein said bottle is configured to match the ergonomic curvature of the filter housing.

9. An apparatus as claimed in claim 1 wherein said filter includes one or more of the following media:

adsorbent media, granular activated carbon, KDF-55, KDF-85, brass filings, CuZn, ion exchange media, ion exchange resin, zeolites, activated alumina, mechanical filtration mesh, oxidation media, activated carbon cloth, carbon mesh, carbon screen, carbon padding, carbon fabric, carbon sponge, carbon foam, carbon felt or carbon fiber mat.

10. The apparatus of claim 9, wherein said media is homogeneously mixed, separated, compartmentalized, orientated, heterogeneously mixed, or any combination thereof.

11. An apparatus as claimed in claim 1 wherein said filter includes filtration pellets that are surface-embedded with antimicrobial agents, biocidal agents, silver, titania, zinc, KDF fines, ion exchange media, zeolites, activated alumina, powdered activated carbon, oxidation media, nanoparticles, microparticles, adsorbing agents, absorbing agents, catalytic agents or any combination thereof.

12. An apparatus as claimed in claim 1 wherein at least two filtration media are chosen as to interact with one another and enhance filtration efficacy.

13. The apparatus of claim 12 wherein said combination of two or more media are chosen such that rate of contaminant reduction is greater with the combination than that with individual media is not housed in combination.

14. The apparatus of claim 12 wherein the phenomena associated with media combinations may be but are not limited to co-precipitation, ion exchange, redox reaction, oxidation, reduction, chelation, flocculation, adsorption, absorption, or any combination thereof.

15. An apparatus as claimed in claim 1 wherein at least two filtration media are used in a layered configuration where influent water contacts one filtration media region or compartment prior to another filtration media region or compartment, in a fashion to enhance contaminant reduction and filtration efficacy.

16. The apparatus of claim 15 wherein the phenomena associated with media combinations may be but are not limited to co-precipitation, ion exchange, redox reaction, oxidation, reduction, chelation, flocculation, adsorption, absorption, or any combination thereof.

17. An apparatus as claimed in claim 1, wherein said filter is configured to reduce at least one contaminant conforming to the NSF/ANSI 42 standard at a given flow rate of at least 0.5 Lpm.

18. An apparatus as claimed in claim 1, wherein said filter is configured to reduce at least one contaminant conforming to the NSF/ANSI 42 standard at a given flow rate of approximately 1.9 Lpm to approximately 2.3 Lpm.

19. An apparatus as claimed in claim 1, wherein said filter is configured to reduce contaminants, organic compounds, inorganic compounds, chloramines, chlorine, particulates, turbidity, arsenic, lead, cadmium, chromium, copper, formazin, pesticides, atrazine, volatile organic compounds, hormones, endocrine disruptors, heavy metals, or the like from drinking water.

20. The apparatus as claimed in claim 1, wherein said filter includes a permeable filter bag with filtration media contained therein.

21. The apparatus as claimed in claim 1, wherein said filter includes one or more filtration chambers.

22. The apparatus as claimed in claim 1, wherein said filter includes a sachet filtration system.

23. A portable, reusable apparatus for treating drinking water, comprising:

a bottle having a mouth;

a filter housing including a water filter and a reservoir, the filter housing configured to be removeably and sealingly attached to the mouth of the bottle; and

a cap configured to scalingly close the reservoir of the filter housing.

24. The apparatus as claimed in claim 23, wherein the filter housing and the bottle are threadably attached.

25. The apparatus as claimed in claim 24, wherein the cap and the filter housing are threadably attached.

26. The apparatus as claimed in claim 23, wherein in the filter is configured to filter water entering and exiting the bottle when the filter housing is attached to the bottle.

27. A portable, reusable apparatus for treating drinking water, comprising:

a generally cylindrical bottle having a mouth;

a generally cylindrical filter housing including a water filter and a reservoir, the filter housing configured to be threadably attached to the mouth of the bottle, the water filter being configured to reduce at least one contaminant conforming to the NSF/ANSI 42 standard as water passes through the water filer and into the bottle at a flow rate of at least approximately 0.5 Lpm; and

a cap configured to threadably close the reservoir of the filter housing.
