Invention field

Present invention relates in general to be used for removing medium and device and the manufacturing and their method of use of pollutent from fluid.

Description of Related Art

For various reasons, need from water-based and/or gas mixture, purify or remove pollutent.For example, the air of purification and/or water may be that following aspect is needed: crowd's general health; Emergency application during natural disaster or terrorist menaces or the attack; Leisure purposes (for example go on a hike or camp); The purposes relevant with biotechnology; Be used for hospital and dental clinic; The production of laboratory " clean room " and semiconductor material.In addition,, industrial pollutants, microorganism and other fragment or infectious substance will not cause crucial health risk from air or tap water, particularly in Susceptible population for example among children, the elderly or the ill crowd if not removing.

It is underground water that all in the world fresh water has more than 97%, and have tens populations with underground water as its unique water source.In the world, the water that can not obtain capacity of the population more than 1,000,000,000 is supported the family.The result is, has every year at least one ten million people to die from water-borne disease, is childs and these philtrums have two million peoples at least.As everyone knows, pathogenic organisms is grown up strong and sturdy in untreated, antihygienic water.Though historically, people thought once that underground water was more purified, because passed through the diafiltration of table soil, show about the research of testing various underground water sources, be positive to Cryptosporidium, Giardia or to both up to 50% active underground water place in the U.S..And, time that can be longer when virus is present in underground water source than bacteria living, propagation farther, partly cause is their small size and colloid physics-chem characteristic.(Azadpour-Keeley etc., EPA Ground Water Issue, 2003, it is incorporated this paper in full into and does reference).Though the bacterial analysis method has occurred a lot of years, has just established phreatic viral indicator in recent years.There are a lot of misunderstandings about the virus in the underground water in past, and comprising: virus is not the normal microflora of animal intestinal, therefore can only be by infected individual the drainage; Lack the detection of viral indicator generally; Think, virus only can in the perceptual cell of survival, exist and propagation and a group to take in a spot of virus be harmless.Some even more important factors of influence virus transhipment comprise the kind and the waterpower stress of sorption in soil water content, temperature, the soil and desorb, pH, salts contg, virus.Also conjecture now, generally speaking, virus is adsorbed to solids and the settling that for example suspends on the solid surface, and this makes them can keep survival for a long time.(Sakoda etc., Wat.Sci.Tech., 35,7, pp.107-114,1997, it is incorporated this paper in full into and does reference).Since 2002, USEPA (The U.S.Environmental Protection Agency) was specified high pollution thing horizontal target (MCLGs) for pathogenic microorganism in the tap water, and it comprises that the set(ting)value of virus is zero.Therefore, removing pollutent, particularly virus from the water source is crucial health problem.

USEPA Science Advisory Board (The U.S.EnvironmentalProtection Agency Science Advisory Board) classifies contaminated tap water one of as maximum publilc health risk.Water-borne pollutent comprises virus, enterovirus (poliovirus for example, Coxsackie virus, ECHO virus, hepatitis virus), rotavirus and other reovirus, the agent of adenovirus Norwalk type, other microorganism, comprise fungi (comprising mould), bacterium (comprises Salmonellas, Shigellae, Yersinia, mycobacterium, enterocolitica, the intestinal bacteria Campylobacter, legionella, Cholera), flagellates, amoeba, Cryptosporidium, Giardia, other protozoon, Protein virus, protein and nucleic acid, sterilant and other agrochemical formulations include organic compounds, mineral compound, halogenated organic compound and other fragment.

The filtering system of standard is mainly based on chemical oxidation, for example reverse osmosis of for example ozonize, and/or UV treatment and/or micro-filtration.Yet these systems are expensive and always can change into and be suitable for handling a small amount of gas, steam or liquid (for example for single user), and a large amount of material (enough hamlets or community).In addition, uncleanly storage facilities once removes pollutent water afterwards before may pollute.Some examples of existing strainer are at United States Patent(USP) Nos. 4,298, discuss in 475 and 4,995,976.

Therefore, also need to be used for removing the filtration medium of pollutent in this area from gaseous state, steam and/or liquor.And, also need to be used to remove the method for pollutent or cleansing soln in this area and device that the high-performance that can provide purifies.

Summary of the invention

The present invention relates to be used for removing " multibarrier " filtration medium, device and the system of pollutent from fluid.The synergy beyond expectation that the present invention particularly obtains based on making up one or more halogenated resins and one or more pollutent sorptive mediums.For example, compare with any independent a kind of filtration medium, the combination of halogenated resin and pollutent sorptive medium not only causes removing the uniform more high-level efficiency of common contaminants (comprising bacterium and virus), and makes the remarkable increase of the fluidic volume that can purify.In addition, another advantage that one aspect of the present invention brought comprises compares significantly higher flow of per unit area with traditional single filter system or equipment.

Another advantage of one aspect of the present invention is, even the combination of halogenated resin and pollutent sorptive medium makes pollutent harmless and the wash-out of pollutent from strainer takes place, also is very little.Therefore, the exhausted filtration medium can be disposed safely at landfill yard.For example, traditional fluid filter or purification system may make pollutent strike off or wash-out from strainer under high pH level and/or temperature variation.When this thing happens, effusive fluid may contain the pollutent than the fluid greater concn that flows into.Yet under high pH condition, halogenated resin (comprising iodinated resin) produces the halogen of higher concentration, and they make common pollutent (comprising bacterium and virus) become harmless.

Another advantage of an aspect comprises: the lasting biocide that is brought by halogenated resin in long-term no process.Because halogenated resin produces halogen continuously, these halogens arrive the surface of strainers, if Fliod fluid decontamination system for a long time need not, halogen just serves as biocide, prevents microbial growth.According to identical mode, the characteristics of described " multibarrier " filtration medium make halogenated resin contact for a long time with fluid to be clean, so improved microorganism killing and detoxification efficient.In addition, the surprising synergetic property of the combination of one or more pollutent sorptive mediums and one or more halogenated resins makes and can particularly use two kinds of littler components in portable system that this has reduced total cost.

Another advantage of an embodiment comprises simplicity of design and makes easily, because owing to described " multibarrier " fluid medium makes common length-to-diameter ratio (for example, for MicrobialCheck

Post, length-to-diameter ratio〉3) become unnecessary.

At last, because the high-level efficiency of " multibarrier " Fliod fluid decontamination system, can use the halogenated resin of low residue, this makes only need remove still less free halogenation material before the fluid after distribution is cleaned.In fact, if the content of halogen height must be enough to killing microorganisms low be enough to obtain the content of halogen of safety in the fluid and purify after the taste and/or the smell of fluidic pleasant, so even might allow halogen stay in the fluid.

The pollutent sorptive medium

The present invention relates to comprise filtration medium, device, system and the sheathing tool (kit) of one or more pollutent sorptive mediums and one or more halogenated resins.In certain embodiments, the present invention relates to one, two, three, four, five, six, seven, eight, nine, ten, 12,15,20,50,100 or more kinds of pollutent sorptive medium.In some aspects, if comprise, for each considers identical or multiple different pollutent sorptive medium more than a kind of pollutent sorptive medium.In some aspects, if comprise more than a kind of pollutent sorptive medium, some media can be identical and other medium can be different.Can make multiple pollutent sorptive medium separated from each other with physics method or chemical method, perhaps can they be combined with physics method or chemical method.Therefore, described filtration medium can have multilayer, and some layers use identical medium and the different pollutent sorptive medium of other layer use.

Because halogen, particularly chlorine and iodine can serve as biocide efficiently, so wish in fluid purifying medium, to comprise one or more halogenated resins.Yet most of halogens make fluid have undesirable taste, so wish just to remove all substantially halogens in case eliminated microorganism.In some cases, for stop or storage, transportation and/or the distribution process of suppression fluid in microbial growth, may wish in fluid, to keep a spot of one or more halogens.

Described pollutent sorptive medium can comprise material known or unknown, that can be used to absorb or adsorb at least a pollutent and/or at least a halogen in this area.Usually, but always be not, sorption is filtered by pore size and is taken place, and adsorption is filtered by electrochemical charge and taken place.This class material can include, but are not limited to the primitive fiber or the micronize thing (for example glass, pottery, wood, synthetic measuring fiber, steel fiber, polymer fiber, nylon fiber, lyocell fiber etc.) of organic or inorganic; Polymkeric substance; Ion or non-ionic material; Pottery; Glass; Mierocrystalline cellulose; Derivatived cellulose (for example phosphorylated cotton or diethylamino ethyl (DEAE) Mierocrystalline cellulose); Fabric is artificial silk, nylon, cotton, wool or silk for example; Metal; Activated alumina; Carbon or gac; Silica; Zeolite; Diatomite; Clay; Settling; Kaolin; Sand; Loam; Activated alumina, hydroxyapatite (calcium hydroxyapatite); Artificial or natural film; Material based on nano ceramics; Nano-alumina fiber (for example

By Argonide-referring to, for example, U.S. Patent No. 6,838,005, it is for referencial use that its full content is incorporated this paper into; Perhaps Structured Matrix ^TMBy GeneralEcology-referring to, for example, Gerba and Naranjo, Wilderness Env.Med., 11,12-16 (2000), it is for referencial use that its full content is incorporated this paper into); Ion exchange resin; Comprise anionite-exchange resin, strongly basic anion exchange resin more especially, for example, as U.S. Patent No. 5,624, described in 567 It is for referencial use that its full content is incorporated this paper into.

In brief, Sometimes be called the iodine washing composition, comprise a plurality of trialkyl amidos, each comprises the alkyl that contains 3 to 8 carbon atoms, and it can remove iodine or iodide from the aqueous solution.

In an example, the electropositive fiber of nano-scale (nonosize), for example U.S. Patent No. 6,838, described in 005 It is for referencial use that its full content is incorporated this paper into, can be used as sorbing material, and it utilizes electric power to assist and holds back pollutent from fluid.For example, if the static electric charge of described filtration medium and particulate matter or pollutent is opposite, electrostatic attraction will promote pollutent to deposit on dielectric surface and keep so.Yet,, will repel if electric charge is similar.The variation of fluidic pH to be filtered and electrolyte concentration changes the surface charge of strainer.For example, reduction pH or interpolation cationic salts will reduce electronegativity, and some absorption is taken place.Because the pH scope of most of tap water is between 5 and 9, employing electronegativity strainer often needs to add acid and/or salt when removing virus.

In brief,

Fiber comprises high electropositive aluminium hydroxide or sapphire whisker, and its diameter is approximately 2 nanometers, and surface-area is at from 200 to 650 meters ²In the scope of/gram.Work as handle

When nanofiber was allocated in the water, they can be connected on electronegativity particle and the pollutent or keep them, comprised silica, organic substance, metal, DNA, bacterium, micelle, virus and other fragment.Except these fibers self, also can be by disperseing described fiber and/or they being adhered on glass fibre and/or other fiber and described fiber is made secondary sorptive medium (secondary sorbent media).Mixture can be processed into nonwoven filter.

Feature in some comprise ten times to 100 times flows to super pore membrane, owing to hold back realize higher by electric charge rather than size and hold back, the intracellular toxin decreasing ratio surpasses〉99.96%, the DNA decreasing ratio surpasses〉99.5% and micron-scale particulate filtration efficient surpassed 99.995%.

In addition, can handle the high surface area material that is shaped to the fine holes structure, hold back so that obtain the enhanced pollutent with water-soluble polymer amount cationic polymers and silver halide mixture, this also be the present invention institute advised (referring to, for example, Koslow, Water Cond.﹠amp; Purif., 2004, it is for referencial use that its full content is incorporated this paper into).This class material may more have resistance to the variation of variable ionic strength (unit price, divalence and trivalent ion), water temp and pH.Yet the next performance of this class may depend on the duration of contact of flow velocity, fluid and the fiber of filtration unit, the hole dimension of filtration medium and the existence of positive zeta-potential (being also referred to as electrokinetic potential).

Any material in these examples of disclosed sorbent material and/or absorber material can in conjunction with or network in the matrix of another kind of material, thereby form composition material or film.

In at least one embodiment, described pollutent sorptive medium comprises carbon and/or gac.Gac can comprise Any shape or form (for example, it can be ball shape, granular or powdery) and can be based on any acceptable source, for example coal (particularly brown coal or bituminous coal) wood, sawdust or Exocarpium cocois (Cocos nucifera L).Gac can be that ANS I/NSF standard 61 and I SO 9002 are that authenticated and/or meet the requirement of U.S.Food Chemical Codex.

Gac may have absorption and/or characterization of adsorption, and this may change according to carbon source.Generally speaking, activated carbon surface is nonpolar, and this causes the avidity to nonpolar adsorbate (for example organic compound).All characterization of adsorptions depend on physical force (for example Van der Waals force), and are saturated by the trim point representative.Because characterization of adsorption moral physical properties, adsorption process are reversible (adopting the variation of heat, pressure, pH etc.).Gac also can chemisorption, at carbon chemical reaction takes place at the interface thus, changes the state (for example, by water dechlorination process) of adsorbate.Generally speaking, loading capacity is directly proportional with surface-area (this is determined by activation degree), and lower temperature generally makes loading capacity increase (unless under situation of viscous liquid).Equally, reducing under the deliquescent pH condition of adsorbate (generally being lower pH), loading capacity increases.As all characterization of adsorptions, need enough duration of contact reach adsorption equilibrium and make the adsorption efficiency maximization with gac.

In at least one embodiment, one or more pollutent sorptive mediums comprise general respirator carbon (

), it is as U.S. Patent No. 5,492, the impregnated granules gac of many purposes purposes in respirator or other fluid purifying apparatus described in 882, and it is for referencial use that this patent full content is incorporated this paper into.URC is by forming with the bituminous coal of suitable binder combination, and its preparation is by the high-temperature steam activation with the controlled group compound dipping (not using chromium, so dispose simply) of copper, zinc, ammonium sulfate and ammonium dimolybdate at stringent condition.
