Description
본 발명은 역삼투막 정수기의 세균오염 방지 및 제균, 항균시스템에 관한 것으로, 더욱 상세하게는 역삼투막 정수기에 있어서 정수량이 적은 정수시스템의 특성상 소비자의 사용편의를 위해 설치하고 있는 저장탱크 또는 압력탱크에 발생하는 세균 오염문제를, 은활성탄과 MF(혹은 UF) 중공사막을 소재로 하여 일체화시킨 제균 필터와, 정수된 물이 저장탱크에 저장되어 있는 동안 외부공기와의 접촉으로 발생하는 세균오염을, 은첨착항균세라믹재(볼)를 충전한 은첨착항균세라믹부재로 완벽하게 제균 및 항균역활을 수행할 수 있는 역삼투막 정수기의 제균 및 항균 시스템에 관한 것이다.The present invention relates to a bacterial contamination prevention, bactericidal, and antibacterial system of a reverse osmosis membrane water purifier, and more particularly, to a storage tank or a pressure tank installed for convenience of a consumer due to the characteristics of the water purification system having a small amount of purified water. Bacterial contamination problems include silver-based charcoal sterilization filter integrated with silver activated carbon and MF (or UF) hollow fiber membrane, and bacterial contamination caused by contact with external air while purified water is stored in the storage tank. The present invention relates to a bactericidal and antimicrobial system of a reverse osmosis membrane water purifier capable of performing a complete bactericidal and antimicrobial role with a silver impregnated antibacterial ceramic member filled with an antimicrobial ceramic material (ball).
현재, 역삼투막 정수기는 오염물질의 제거에 있어서 지금까지 개발된 그 밖의 정수방식에 비해 탁월하다고 알려져 있다. 하지만, 역삼투막 정수기에서 역삼투막 필터를 통과한 정수수는 역삼투막의 우수한 제거능력 때문에 원수보다 pH가 낮아지는 경향이 있고 또한, 사용초기의 역삼투막 필터 소재에서 냄새가 나고 물맛이 쓰다는 것이 지적되고 있으며, 이 문제 때문에 대부분의 역삼투막 정수기의 제조업체는 역삼투막 필터 후단에 활성탄 필터(별칭:후처리 활성탄 필터)를 사용함으로써 해결하려고 하지만, 이 활성탄 필터는 단시간에 세균에 오염되고 그 세균을 저장탱크(역삼투막 정수기는 미세한 기공을 통해 정수하기 때문에 정수량이 적어 거의 모든 역삼투막 정수기의 제조업체에서 채택하고 있다)로 흘러 들어가기 때문에 이 활성탄 필터를 사용하는 것이 저장탱크내의 정수수를 세균에 오염시키는 주된 원인이 되고 있다. 또한 이 활성탄 필터에서 발생한 미세한 활성탄 분진도 저장탱크 안으로 흘러 들어가 세균의 영양물질의 되기 때문에 저장탱크 내에서의 세균의 오염을 보다 더 늘리고 있다.Currently, reverse osmosis membrane water purifiers are known to be superior to other water purification methods developed so far in the removal of contaminants. However, it is pointed out that the purified water passed through the reverse osmosis membrane filter in the reverse osmosis membrane water purifier has a lower pH than the raw water because of the excellent removal ability of the reverse osmosis membrane, and also smells and tastes water in the initial reverse osmosis membrane filter material. As a result, most manufacturers of reverse osmosis membrane water purifiers try to solve the problem by using activated carbon filters (alias: post-treatment activated carbon filters) at the back of the reverse osmosis membrane filter. Because of the small amount of purified water, which is used by almost all manufacturers of reverse osmosis membrane water purifiers, the use of this activated carbon filter is the main cause of contaminating the purified water in the storage tank with bacteria. In addition, fine activated carbon dust generated from the activated carbon filter flows into the storage tank and becomes a nutrient for bacteria, thereby increasing the contamination of bacteria in the storage tank.
또한, 일반적인 역삼투막 정수기 저장탱크는 플라스틱(ABS수지, PE수지 등)으로 제작되는데, 만수된 물은 통상 한꺼번에 100% 사용되지 않고 일부의 물만이 사용되며, 그물이 사용될 때 유입되는 공기와 접촉하여 세균에 오염되거나 저장탱크 내의 남은 물과 새로 들어온 정수수가 섞이는 과정에서도 공기와 접촉하여 세균에 다시 오염이 되는 것이다.In addition, the general reverse osmosis membrane water purifier storage tank is made of plastic (ABS resin, PE resin, etc.), the full amount of water is usually not 100% at a time, only part of the water is used, and when the net is used in contact with the incoming air bacteria Is contaminated by bacteria in contact with air even when the water is contaminated or the remaining water in the storage tank is mixed with fresh water.
결과적으로, 역삼투막 정수기는 매우 미세한 기공의 역삼투막 필터를 통과해 수중의 각종 오염물질을 완벽하게 제거하더라도 역삼투막 필터 후단에 활성탄필터(별칭:후처리 활성탄 필터)에서의 세균의 오염 문제가 근본적으로 해결되지 않는 한 저장탱크내의 정수수의 세균 오염은 피할 수 없는 문제이다.As a result, even if the reverse osmosis membrane water purifier completely removes various contaminants in the water through a very fine pore reverse osmosis membrane filter, the problem of bacterial contamination in the activated carbon filter (alias: post-treatment activated carbon filter) after the reverse osmosis membrane filter is not fundamentally solved. Unless otherwise, bacterial contamination of purified water in storage tanks is an unavoidable problem.
따라서, 이와 같은 세균 문제를 해결하기 위해 대부분의 정수기 제조업체는 소비자(사용자)에게 저장탱크를 정기적(월 3회-4회)으로 청소하도록 권하고 있는 데, 현실적으로 실시되는 것은 어렵고 그 효과도 미지수로 근본적인 해결책이 되지 않고 있으며, 또한 정수 시스템 안에 자외선 램프를 설치하여 물을 통과시키는 방법을 취하고 있으나, 완전한 살균효과가 없을 뿐만 아니라 자외선에 의한 소재 [정수기의 각 부분에 사용되고 있는 소재(ABS수지, PE수지 등)]의 부식문제 등 새로운 문제가 생겨나 실용성이 없고 세균문제의 근본적인 해결이 되지 않는다.Therefore, to solve this bacterial problem, most water purifier manufacturers recommend that consumers (users) clean the storage tank regularly (3-4 times a month), which is difficult to carry out in reality and its effect is unknown. The solution is not solved, and the UV lamp is installed in the water purification system to pass the water, but it does not have a perfect sterilization effect and the material caused by ultraviolet light [A material used for each part of the water purifier (ABS resin, PE resin) New problems such as corrosion problems are not practical, and they are not a fundamental solution to bacterial problems.
그밖에 싱크대 밑에 설치하는 언더싱크 타입의 역삼투막 정수기의 경우에 있어서도 일반적으로 압력탱크에서 취수꼭지로 물을 추출하는 과정에서 활성탄 필터를 사용하는데, 이 활성탄 필터는 세균에 오염되기 쉽기 때문에 취수꼭지로부터 취수하는 물은 세균오염의 면에서 안전을 보장받을 수 없는 상태로 방치되고 있는 것이다.In addition, in the case of the undersink reverse osmosis membrane water purifier installed under the sink, an activated carbon filter is generally used in the process of extracting water from the pressure tank to the intake faucet, which is easily contaminated by bacteria. Water is left unattended in terms of bacterial contamination.
본 발명은 위와 같이 세균오염 문제를 경제성 및 실용성을 만족시키면서 인체에 안전한 방법으로 완벽하게 해결하고자 하는 것으로, 역삼투막 정수기의 정수시스템 최종 말단에 은활성탄과 MF(혹은 UF)중공사막을 소재로 하여 일체화시킨 제균필터를 장착함으로써, 은활성탄은 세균의 발생을 억제함과 동시에 냄새를 제거하는 역할을, MF(혹은 UF) 중공사막은 세균과 활성탄에서 발생되는 미분진을 완벽하게 제거함으로써, 세균과 세균의 영양물질인 활성탄 미분진이 저장탱크 안에 들어가는 것을 완전히 차단시킨다.The present invention is to completely solve the bacterial contamination problem in a safe manner to the human body while satisfying the economics and practicality, integrated with silver activated carbon and MF (or UF) hollow fiber membrane at the end of the water purification system of the reverse osmosis membrane water purifier. By installing the antibacterial filter, the silver activated carbon suppresses the generation of bacteria and removes the smell. The MF (or UF) hollow fiber membrane completely removes the fine dust generated from the bacteria and activated carbon. Activated charcoal dust, a nutrient for nutrients, is completely blocked from entering storage tanks.
또한, 저장탱크 안에 정수수가 공기의 접촉에 의해 오염되는 것을 방지하기 위하여 저장탱크내의 정수수에 은첨착 항균세라믹 부재를 형성함으로써, 은첨착 항균세라믹재(볼)에서 용출되는 항균금속인 은이온이 저장중의 정수수 안으로 균일하게 퍼지면서 세균오염의 억제 및 방지하는 역할을 수행하도록 한다.In addition, in order to prevent the purified water from being contaminated by contact of air in the storage tank, a silver-attached antibacterial ceramic member is formed in the purified water in the storage tank, whereby silver ions, which are antibacterial metals eluted from the silver-attached antibacterial ceramic material (balls), are stored. Spread uniformly into the purified water in the water to act to inhibit and prevent bacterial contamination.

본 발명의 기술 사상을 구체화함에 있어서, 구성부품들의 사양에 특별한 성능 및 구조가 요구되는데, 이하 본 발명의 사용 상태의 구체적인 예를 도면에 의거하여 상세히 설명하면 다음과 같다.In embodying the technical idea of the present invention, a special performance and structure are required for the specification of the component parts. Hereinafter, specific examples of the use state of the present invention will be described in detail with reference to the accompanying drawings.
도 1 은 본 발명의 역삼투막 정수기의 정수 시스템의 수배관도를 설명하는 것으로 이것을 이용하여 개략적인 물의 정수과정을 설명하면 수도꼭지(도면에는 도시되어 있지 않음)에 연결되는 원수공급 호스를 통해 물이 역삼투막 정수기의 본체 내로 유입되고 전처리여과필터(1)(이것은 주로 녹성분과 부유하고 있는 고형물을 제거하는 역할을 한다)에 연결된다. 그리고 원수급수밸브(2)를 통해 가압펌프(3)에 연결되지만 저장탱크(10)의 수위센서가 만수를 감지하면 원수급수밸브(2)는 닫히고 가압펌프(3)는 동작을 멈춘다.1 illustrates a water pipe diagram of a water purification system of a reverse osmosis membrane water purifier of the present invention. When the water purification process is schematically described using this, the water is reversed through a raw water supply hose connected to a faucet (not shown). It is introduced into the main body and connected to the pretreatment filtration filter (1), which mainly serves to remove rust and suspended solids. And the raw water supply valve 2 is connected to the pressure pump 3, but when the water level sensor of the storage tank 10 detects full water, the raw water supply valve 2 is closed and the pressure pump 3 stops the operation.
또한, 전처리활성탄필터(4)에서 수중의 염소, 발암물질, 유기성 화합물질이 제거되고 역삼투막필터(5)에 연결되어 0.0001미크론 이상의 수중에 용해되어 있는 대부분의 오염물질과 유해성분이 제거된다. 이때 역삼투막필터(5)에 의해 제거된 불순물은 농축수 조절밸브(6)을 통해 물맛이 개선되고 냄새와 가스 성분이 제거된다.In addition, the pretreatment activated carbon filter 4 removes chlorine, carcinogens and organic compounds in the water, and is connected to the reverse osmosis membrane filter 5 to remove most contaminants and harmful components dissolved in water of 0.0001 micron or more. At this time, the impurities removed by the reverse osmosis membrane filter 5 are improved in water taste through the concentrated water control valve 6 and odor and gas components are removed.
후처리활성탄필터(7)를 거친 물은 도 2a에 나타낸 바와 같이 본 발명에 의한 은활성탄(13a)과 MF(혹은UF)중공사막(12a)이 장착되어 있는 제균필터(8a)를 통과하는데, 이때 은활성탄은 물맛을 개선함과 동시에 은이온을 용출하여 세균의 번식을 막으며, 또한 그 은이온은 저장탱크에 흘러 탱크내의 항균을 돕는 역할을 한다.한편MF(혹은UF)중공사막(12a)은 활성탄에서 미세한 분진을 완벽하게 제거하고 은활성탄에서 처리할 수 없었던 세균을 완벽하게 제거하는 역할을 수행한다.Water passing through the post-treatment activated carbon filter 7 passes through the antibacterial filter 8a equipped with the silver activated carbon 13a and the MF (or UF) hollow fiber membrane 12a according to the present invention, as shown in FIG. 2A. At this time, silver activated carbon improves the taste of water and elutes silver ions to prevent the growth of bacteria, and the silver ions flow to the storage tank to help antibacterial in the tank. On the other hand, MF (or UF) hollow fiber membrane (12a) ) Completely removes fine dust from activated carbon and completely removes bacteria that could not be processed on silver activated carbon.
또한, 본 발명에 의한 제균필터(8a)는 도 2a에서 나타내는 은활성탄(13a)과 MF(혹은UF)중공사막(12a)을 도 2b와 같이 각각 은활성탄필터(13b)와 MF(혹은UF) 중공사막(12b)으로서 분리하여 양쪽 필터를 모두 장착하여 사용한다거나, 또는 도 2c와 같이 앞에 서술한 제균필터(8a)를 후처리활성탄필터(7)의 대체필터(8b)로서 장착하여 사용하더라도 앞에 기술한 제균필터(8a)와 같은 역할을 수행할 수 있다.In addition, the antibacterial filter 8a according to the present invention uses the silver activated carbon 13a and MF (or UF) hollow fiber membrane 12a shown in FIG. 2A, respectively, as shown in FIG. 2B. The silver activated carbon filter 13b and MF (or UF) are respectively shown in FIG. Even if both filters are separated and used as the hollow fiber membrane 12b, or the disinfection filter 8a described above is used as the replacement filter 8b of the aftertreatment activated carbon filter 7, as shown in FIG. It can play the same role as the disinfection filter 8a described above.
상기의 처리를 거친 정수수는 튜브를 통해 저장탱크(10)에 저장되는데, 저장탱크(10)의 정수수는 일정시간동안 정체(정수기를 사용하지 않을 때), 추출(정수기의 사용으로 정수수가 추출될 때), 유입(저장탱크에 정수수가 새로 유입될 때)하는 과정을 반복하면서 외부의 공기와 접촉되어 다시 쉽게 세균에 오염되도록 되는데, 종래의 정수기는 이런 저장탱크(10)내의 세균 오염문제를 근본적으로 해결할 수 있는 방안을 제시할 수 없었다.The purified water after the treatment is stored in the storage tank 10 through the tube, the purified water of the storage tank 10 is stagnant (when not using the water purifier) for a predetermined time, the extraction (using the water purifier to extract the purified water When a new water is introduced into the storage tank, the water is repeatedly contacted with the outside air to be easily contaminated by bacteria. The conventional water purifier is a fundamental solution to the bacterial contamination problem in the storage tank 10. Could not suggest a solution.
도 3 은 본 발명에 의한 저장탱크 내에서의 향균시스템을 나타낸 것으로, 은첨착항균세라믹볼(또는 은첨착항균세라믹재, 이하 은첨착항균세라믹볼이라 칭함)(15)과 부레(14)가 형성되어 있는 은첨착항균세라믹부재(9)를, 외부공기와의 접촉에 의해 세균오염 가능성이 있는 저장탱크(10)내에 형성한 것이다.3 shows an antimicrobial system in a storage tank according to the present invention, in which silver-impregnated antimicrobial ceramic balls (or silver-impregnated antibacterial ceramic materials, hereinafter referred to as silver-impregnated antibacterial ceramic balls) 15 and bures 14 are formed. The silver-attached antibacterial ceramic member 9 is formed in the storage tank 10 in which bacteria may be contaminated by contact with external air.
이때, 은첨착항균세라믹부재(9)내에 들어있는 음첨착항균세라믹볼(15)은 물에 젖어 세라믹볼 내부의 다공성 속으로 물이 흡수된다. 물에 젖은 은첨착항균세라믹볼(15)은 항균금속이온(온이온)을 방출하는데, 이와 같이 방출된 항균 금속이온은 저장탱크(10)의 정수수 중으로 도 3에서 파선(---)같이 천천히 퍼지게 된다. 은이온은 그 밖의 금속이온보다도 세균에 대한 살균능력이 뛰어나다고 보고되고 있으며, ppb단위의 은이온은 인체에 무해하다는 것이 밝혀졌고, 유럽 등에서는 은이온을 이용한 음용수의 살균처리가 정수처리방식으로서 일방화되고 있다. 하지만 은이온은 미국 등의 일부 나라에서는 음용수의 수질기준상, 2차 오염물질(SECONDARY CONTAMINANT)로서 그 허용기준은 50ppb 이하로 규제하고 있기 때문에, 본 발명에서는 은첨착항균세라믹부재를 저장탱크 내에 띄우든가 고정하여 탱크 내에서 균일하게 은이온이 퍼지게 함으로써, 미량의 용출(10ppb∼15ppb)로 항균효과를 극대화시켰으며 허용기준치인 50ppb을 넘지 않도록 했다. 이러한 조건하에서 은첨작항균세라믹볼(15)에서 용출되는 은이온은 저장탱크내의 수중으로 천천히 퍼지면서 외부공기와의 접촉으로 유입된 세균의 대사작용을 파괴, 완벽하게 사멸시킴으로써 항상 신선하고 청결한 정수수로서 유지시킨다.At this time, the negatively-attached antibacterial ceramic ball 15 contained in the silver-impregnated antibacterial ceramic member 9 is soaked in water and water is absorbed into the porous inside the ceramic ball. The silver-attached antibacterial ceramic ball wetted with water 15 emits antimicrobial metal ions (on ions). The antimicrobial metal ions released as described above are slowly discharged as shown by a dashed line (---) in FIG. 3 in the purified water of the storage tank 10. Spreads. Silver ions have been reported to be more effective in sterilizing bacteria than other metal ions, and it has been found that silver ions in ppb units are harmless to humans. In Europe, drinking water using silver ions is used as a water treatment method. It is unified. However, in some countries, such as the United States, because the water quality standards of drinking water, the secondary standards (SECONDARY CONTAMINANT) is regulated to less than 50ppb, in the present invention, silver-impregnated anti-ceramic ceramic members appear in the storage tank By dispensing silver ions and spreading the silver ions uniformly in the tank, a small amount of elution (10ppb to 15ppb) maximized the antimicrobial effect and prevented it from exceeding 50ppb. Under these conditions, silver ions eluted from the silver antimicrobial ceramic ball 15 slowly spread into the water in the storage tank, destroying and completely killing the metabolism of bacteria introduced by contact with external air, thereby completely purifying water as fresh and clean water. Keep it.
또한, 저장탱크(10)의 물이 일정시간 동안 정체(정수기를 사용하지 않을 때), 추출(정수기의 사용으로 정수수가 추출될 때), 유입(저장탱크에 정수수가 새로 유입될 때)하는 과정을 반복하면서 정수수중의 은이온의 농도가 변화하면 다시 은첨착항균세라믹볼에서 일정량의 은이온이 용출, 농도가 평형하게 유지되어 저장탱크(10)내의 정수수는 항상 무균의 상태로 유지된다.In addition, the process of the water in the storage tank 10 stagnated for a predetermined time (when not using a water purifier), extraction (when purified water is extracted by using the water purifier), inflow (when purified water is newly introduced into the storage tank) When the concentration of silver ions in the purified water is changed while repeating, the silver ions are eluted from the silver-impregnated antibacterial ceramic ball again, and the concentration is maintained in equilibrium so that the purified water in the storage tank 10 is always kept aseptic.
결과적으로 사용자는 정수기의 사용 중이거나 또한, 일정시간동안 정수기를 사용하지 않을 때에도 세균 등의 오염문제로부터 해방된다.As a result, the user is free from contamination problems such as bacteria even when the water purifier is in use or when the water purifier is not used for a certain time.
도 4 는 언더싱크 타입의 역삼투막 정수기에 있어서 제균의 시스템을 나타낸 것으로, 수도꼭지(도면에는 도시하지 않았음)에 연결되어 원수 공급호스를 통해 수도수가 정수기의 본체로 유입되어 전처리여과필터에 연결된다. 이것은 녹성분과 수중에 부유하고 있는 고형물을 제거하는 역할을 한다.Figure 4 shows the system of disinfection in reverse osmosis membrane water purifier of the undersink type, it is connected to the tap (not shown), tap water is introduced into the body of the water purifier through the raw water supply hose is connected to the pretreatment filter. This removes rust and solids suspended in water.
또한, 일반적으로 수압이 낮은 경우, 사용되는 가압펌프(3)을 통해 전처리활성탄필터(4)로 수중의 염소, 발암물질, 유기성화학물질이 제거된 후, 오토셧오프밸브(16)를 거쳐 역삼투막필터(5)에 연결된다. 이 때 오토셧오프밸브(16)의 역할은 정수된 물이 압력탱크(18)에 저장되어 일정압력(1∼2kgf/cm2)이 발생되면 원수의 입수를 차단해 준다. 또한 역삼투막필터(5)에서는 0.0001미크론 이상의 오염물질과 유해성분이 제거되고 역삼투막필터(5)를 통과하지 않은 불순물 등은 농축수 조절밸브(6)를 통해 외부로 배출되며 정수된 정수수는 후처리활성탄필터(7)를 통해 물맛이 개선되고 냄새와 가스성분이 제거된 후, 압력탱크(18)의 압력을 감지하는 수압스위치(17)을 거쳐 압력탱크(18)에 저장된다.In general, when the water pressure is low, the chlorine, carcinogen, and organic chemicals in the water are removed by the pretreated activated carbon filter 4 through the pressurized pump 3 used, and then the reverse osmosis membrane is passed through the auto shutoff valve 16. Is connected to the filter (5). At this time, the role of the auto shutoff valve 16 is the purified water is stored in the pressure tank (18) when a certain pressure (1 ~ 2kg f / cm 2 ) occurs to block the intake of raw water. In addition, in the reverse osmosis membrane filter (5), contaminants and harmful components of 0.0001 micron or more are removed, and impurities that do not pass through the reverse osmosis membrane filter (5) are discharged to the outside through the concentrated water control valve (6). After the water taste is improved (7) and odors and gas components are removed, the water is stored in the pressure tank 18 via a water pressure switch 17 for sensing the pressure of the pressure tank 18.
이때, 압력탱크(18)에 물이 저장되어 그것에 의해 일정압력(1∼2kgf/cm2)이 발생하면 수압스위치(17)는 이것을 감지하여 가압펌프(3)의 전원이 끊어지고 오토셧오프밸브(16)는 원수(수도수)의 입수를 차단시킨다.At this time, when water is stored in the pressure tank 18 and a constant pressure (1 to 2 kg f / cm 2 ) is generated thereby, the water pressure switch 17 detects this and the power of the pressure pump 3 is cut off and auto shuts off. The valve 16 shuts off the raw water (tap water).
도 5는, 도 4에서 나타낸 제균필터부분에 대한 상세도로서 압력탱크(18)에 저장된 정수수는 소비자(이용자)가 물을 추출하려고 해서 취수꼭지(19)를 열면 은활성탄(13a)과 MF(혹은UF)중공사막(12a)이 장착된 제균필터(8a)를 통과하는데 이때 은활성탄(13a)은 물맛을 더욱 개선함과 동시에 세균의 번식을 막는 항균 역할은 하며 MF(혹은UF)중공사막(12a)은 활성탄에서 유출되는 미세한 분진을 완벽하게 제거하고 은활성탄에서 처리할 수 없었던 세균을 완벽하게 제거하는 역할을 수행한다.FIG. 5 is a detailed view of the sterilization filter part shown in FIG. 4, wherein the purified water stored in the pressure tank 18 is activated silver 13a and MF (when the consumer (user) opens the intake faucet 19 to extract water. Or UF) through the antibacterial filter (8a) equipped with a hollow fiber membrane (12a), the silver activated carbon (13a) further improves the taste of water and at the same time acts as an antibacterial to prevent the growth of bacteria and MF (or UF) hollow fiber membrane ( 12a) completely removes fine dust flowing out of activated carbon and completely removes bacteria that could not be treated in silver activated carbon.
결과적으로 사용자는 정수기의 사용 중 또는 일정시간 정수기를 사용하지 않을 때라도 세균의 오염 등에서 해방된다.As a result, the user is free from contamination of bacteria even when the water purifier is in use or when the water purifier is not used for a certain time.
도 6 은 일반적으로 역삼투막 정수시스템을 채택하고 있는 역삼투막 정수기의 저장탱크 내에 발생하고 있는 일반세균수의 측정결과이다. 각 지역에서 사용 중인 정수기를 임의로 선택하여 측정한 결과이다. 모든 수치가 『먹는물』의 일반세균의 기준치(100CFU/㎖)보다 휠씬 높았다.6 is a measurement result of the general bacterial count occurring in the storage tank of the reverse osmosis membrane water purifier which generally adopts the reverse osmosis membrane water purification system. This is the result of selecting the water purifier used in each area arbitrarily. All the values were much higher than the standard bacteria (100 CFU / mL) of 『Eating Water』.
도 7 은 본 발명에 의한 제균 및 항균 시스템을 장착한 역삼투막 정수기를 가지고 53주간(약 1년간)에 거친 저장탱크내의 일반 세균수를 측정한 결과를 나타낸 것이다. 53주간의 장기간을 거쳐도 일반세균수가 "0" 이라는 완벽한 항균효과를 얻을 수 있었다.Figure 7 shows the result of measuring the general bacteria count in the rough storage tank for 53 weeks (about 1 year) with a reverse osmosis membrane water purifier equipped with the antibacterial and antibacterial system according to the present invention. Even after a long period of 53 weeks, the normal bacterial count was able to obtain a perfect antimicrobial effect of "0".
도 8 은 본 발명에 의한 제균 및 항균 시스템에 사용되는 은첨착항균세라믹부재내에 충진되어 있는 은첨착항균세라믹볼의 항균력 테스트이다. 은첨착항균세라믹볼이 들어있는 플라스크와 은첨착항균세라믹볼을 넣지 않은 플라스크(Control)의 일반세균의 자연 증가수를 측정하여 비교한 것이다. 도 8에서 보는 바와 같이 Control은 크게 증가하고 있는 것에 반해, 은첨착항균세라믹볼이 들어있는 플라스크 내의 일반 세균수는 8시간 후부터는 거의 "0"이 된 것을 볼 때, 은첨착항균세라믹볼이 뛰어난 항균력을 지니고 있는 것을 알 수 있다.8 is an antimicrobial activity test of silver-impregnated antibacterial ceramic balls filled in silver-impregnated antibacterial ceramic members used in the bactericidal and antibacterial system according to the present invention. The natural increase in the number of ordinary bacteria in a flask containing silver-impregnated antibacterial ceramic balls and a flask without silver-impregnated antibacterial ceramic balls was measured and compared. As shown in FIG. 8, the control is greatly increased, whereas the number of ordinary bacteria in the flask containing the silver-impregnated antimicrobial ceramic ball becomes almost "0" after 8 hours. It can be seen that it has.
도 9 는 역삼투막 정수기에서 일반적으로 사용되고 있는 후처리활성탄필터의 통과수에 대한일반세균 측정결과와 또한 각 제조사 마다의 은활성탄 필터의 통과수에 대한 일반세균 측정결과(항균성능)이다.도 10 은 본 발명에 의한 제균필터(8b)의 내부소재로서 사용되는 MF(혹은UF)중공사막의 일반적인 사양을 나타낸 것이다.9 is a general bacteria measurement results for the pass water of the after-treatment activated carbon filter commonly used in the reverse osmosis membrane water purifier, and a general bacteria measurement results (antibacterial performance) for the pass water of the silver activated carbon filter for each manufacturer. The general specification of the MF (or UF) hollow fiber membrane used as the internal material of the bactericidal filter 8b according to the present invention is shown.
본 발명은 정수량이 적은 시스템의 특성상 저장탱크를 설치하고 있는 역삼투막 정수기에 있어서, 은활성탄과 MF(혹은UF)중공사막을 소재로 하여 일체화시킨 제균필터를 장착하여, 역삼투막 필터를 통과한 정수수의 pH하락, 냄새 발생, 맛 변화 등의 문제를 해결하기 위해 설치하고 있는 활성탄 필터(별칭:후처리활성탄필터)에서 나오는 세균과, 그 활성탄에서 발생되는 세균의 영양분이 되는 미분진이 저장탱크 내로 유입하는 것을 차단함으로써 저장탱크내의 오염을 방지한다.The present invention provides a reverse osmosis membrane water purifier in which a storage tank is installed due to the characteristics of a small amount of purified water, and is equipped with a sterilization filter integrated with silver activated carbon and an MF (or UF) hollow fiber membrane, and the pH of the purified water passed through the reverse osmosis membrane filter. The inflow of microorganisms from the activated carbon filter (alias: post-treatment activated carbon filter) installed in order to solve problems such as dropping, odor generation and taste change and nutrients of bacteria generated from the activated carbon are introduced into the storage tank. Blocking prevents contamination in the storage tank.
또한, 은첨착항균세라믹부재를 저장탱크 내에 형성함으로써, 은첨착항균세라믹볼에서 용출되는 50ppb 이하의 미량(10-15ppb)의 은이온이 물의 대류작용에 의하여 균일하게 퍼지면서, 저장탱크 내에 저장되고 있는 정수수가 외부 공기와의 접촉에 의해 세균으로부터 오염되는 것을 방지한다.In addition, by forming the silver-impregnated antibacterial ceramic member in the storage tank, a trace amount (10-15ppb) or less of silver ions eluted from the silver-impregnated antibacterial ceramic ball is uniformly spread by the convection action of water and stored in the storage tank. Prevents purified water from being contaminated by bacteria by contact with outside air.
또한, 언더싱크 타입의 역삼투막 정수기의 경우는 압력탱크와 취수꼭지 사이에 제균필터를 사용하여 취수꼭지에서 추출되는 물이 제균필터를 통하는 시스템으로 함으로써 완벽하게 제균되는 시스템을 만들 수 있다.In addition, in the case of the undersink type reverse osmosis membrane water purifier, using a disinfection filter between the pressure tank and the intake faucet, a system through which the water extracted from the intake faucet passes through the disinfection filter can be made.
이와 같은 시스템으로 완전하게 세균 오염문제를 해결하여 정수기의 사용 중 혹은 정수기를 일정기간 사용하지 않을 때도 그 세균 문제에서 해방되는 것은 물론, 빈번한 물탱크의 세척에 의한 비경제성, 비실용성 문제와 그리고 자외선 필터를 사용함으로써 발생되는 인체의 안전성 문제, 소재(정수기의 각 부분에 사용되고 있는 ABS수지, PE수지 등)의 부식문제 등을 해결할 수 있다.This system completely solves the problem of bacterial contamination, freeing the bacteria from the water purifier during use or when not using the water purifier for a certain period of time. The use of the filter can solve the safety problems of the human body and corrosion problems of materials (ABS resin, PE resin, etc. used in each part of the water purifier).
