The swift electron of attached dose of surface to contaminant molecule that may be present one or more of shifts；And (ii) is from adsorbent
In the case that composition discharges any active component, concentration should be in WHO in the limit of safe drinking water, thus avoiding providing
The needs of second level clean unit.
The gravity feeding storage water purifier of the present invention includes film cloth, and it has ground floor and the second layer.On the one hand,
Granular sterilization composition is placed between ground floor and the second layer.Film cloth (is such as subject to from raw water using depth-type filtration mechanism
The water of pollution) in remove dust, sand and deposit.Graininess sterilization composition can be by leaching in water simultaneously silver ion
And by absorption on the boehmite nanostructure of organic formwork for the virus or the chemical interaction with the silver ion leaching,
To eliminate the bacterium in drinking water and virus.Print by propositions such as T.Pradeep before us for the exemplary sterilization composition
It is described in degree patent application 947/CHE/2011 and 20070608, the full content of described patent application is with way of reference
It is expressly incorporated herein.
On the one hand, the use of water purifier may need manually by water (as contaminated water) with 1 liter/min to 2 liters/
The typical flow rates of minute are poured on film layer of cloth.On the one hand, flow rate can be 0.1 liter/min to 5 liters/min.
The water passing through can contact graininess sterilization composition, and wherein silver ion can be leached to water from sterilization composition.Through film

The advantage of gravity feeding storage water purifier is as follows：(i) due to only using single container, so reducing Water warfare
The purchase cost of device.(ii) because the concentration of silver ion remaining in water is less than or is far below WHO limit, therefore do not need further
Purified water.(iii) greatly improve effective duration of each circulation of Water warfare, thus promoting the net of supply consumer
Change the faster availability of drinking water.
From prior art it is also known that the technology for purifying drinking water needs (Advances in of rational time of contact
Water treatment by adsorption technology, Ali etc., Nature Protocols, 2006,1 (6),
2661).In the case of activated carbon, the absorption of pollutant may the needs air-land combat (EBCT) of 10 minutes
(Predicting GAC performance with rapid small-scale column test, Crittenden etc.,
J.Am.Water Works Assoc.1991,83,77–87).Dechlorination is gone typically quickly by activated carbon, because it is alive
Redox reaction between charcoal and chlorine for the property, and be not therefore adsorption process (Reduction of aqueous free
Chlorine with granular activated carbon-pH and temperature effects, Suidan etc.,
Environ.Sci.Technol., 1977,11 (8), 785 789).Similarly, the activated carbon of immersion silver had been used for 30 seconds
EBCT remove bacterium (Silver-embedded granular activated carbon as an from drinking water
Antibacterial medium for water purification, Bandyopadhyaya etc.,
J.Chem.Technol.Biotechnol.,2008,83,1177–1180).Bridges etc. is in PCT Publication application 2008/
It has been reported that the sterilised medium based on chlorine and bromine needs the time of contact of 1 second to 3 seconds to kill microorganism in 106276.
Active sterilization agent generally can be leached in the microbicide composition from the water passing through, and containing active sterilization agent
Water is kept the time of restriction.Generally, kill microorganism can complete in two ways：Relatively low time and high dose or higher when
Between and low dosage.The second way is favourable, because preventing extra filtration step to remove excessive bactericidal agent from water
Need.Mistry etc., in PCT Publication application PCT Publication application 2004/000732, for the sterilised medium based on chlorine, uses
With the standing time implementing more than 30 minutes.
It is to come using described composition purifying drinking water by being filled in composition in film cloth, the EBCT of 0.1 second is available for
For the contact between composition and water.The design of the water purification installation of our here reports is to be purified based on a kind of composition
Water, described composition is boehmite nanometer framework (Ag-OTBN) of the organic formwork based on dipping Nano silver grain.Preparation side
Method and its purposes in water purification have been described in detail in our earlier patents application 947/CHE/2011, described special
Profit application is herein incorporated by reference.Although not wishing to be bound by theory, it is believed that the sterilizing activity mechanism of Nano silver grain
It is the release due to silver ion in water.This silver ion releasing mechanism is used for the activity of sterilizing before.For Ag-OTBN,
Have proven to the sustained release of the silver ion in the water more than 1,500 liters of volume capacities before.In water, the concentration of silver ion is usual
It is about 20ppb, and the limit far below the 100ppb for safe drinking water defined for the WHO.
For avoiding using two containers it is necessary to store in a vessel purified water, and avoid in another container
The needs of middle storage raw water (as contaminated water).At described aspect, raw water (as contaminated water) with go out
Antimicrobial composition contacts in the porch of the container for storing purified water.Preferably, microbicide composition is filled in two-layer
Between film cloth.
However, the key restriction factors of the use of microbicide composition in film cloth be microbicide composition with non-purified
The contact of water (as contaminated water) is minimum.As illustrative embodiment, the Ag-OTBN particle of 20x60 sieve mesh can be clipped in two
Between tunic cloth.The size of such a cylinder filter element is 10cm (D) × 10cm (H), and wherein Ag-OTBN accounts for 1cm's
Depth.For the typical flow rate of 1L/min, EBCT is calculated as 0.1 second.Generally, in online water purifier, implement 2 seconds
To the EBCT of 5 seconds.
Effectively the second aspect of sterilizing activity is to provide the standing time of feedwater when there is the bactericidal agent of leaching in water.
This is all genuine in the nearly all bactericidal agent become known for drink water purifying.This is previously reported by (Mistry's etc. some
PCT Publication application PCT Publication application 2004/000732；Antibacterial Activity and Mechanism of
Action of the Silver Ion in Staphylococcus aureus and Escherichia coli, Jung
Deng, Appl Environ Microbiol., 2008,74 (7), 2171；Observations on Halogens as
Bathing Water Disinfectants, Brown etc., J.Appl.Microbiol., 1966,29,3,559) reported in
Road.Higher with sterilizing agent concentration used in water, the standing time of needs is then fewer, and vice versa.However, using more
The bactericidal agent of high concentration is probably unfavorable, because：(i) exceed the permission limit of drinking water concentration need additional step so that
Remove bactericidal agent, and the sterilizing agent concentration of (ii) excess also can result in and the organic loading generally finding in drinking water
Redox and/or other reaction.
Standing time can be realized by some modes, described mode depend primarily on required standing time lasting when
Between and water purifier design complexity：(i) to consumer with regard to product simple notification, when illustrating to need fixing placement
Between to kill microorganism completely, (ii) realizes the travel path of water, and wherein before reaching the outlet of water receptacle, water is in Water warfare
Lentamente move in device, (iii) is arranged on to stop the device of water flowing at outlet tap, and wherein user is being filled with water appearance
Connect described device after device, and described device cost regular time opens obstruction water being flow through to tap, and
(iv) device being located in water purifier, described device is activated by hydraulic pressure and deactivates after the predetermined time period
(described device may or may not be integrated into the obstruction that water flows through tap).In the concrete condition of the present invention, in outlet tap
Above analogue means is installed, for controlling water standing time in a reservoir.The general structure of device is based on mechanical watch, example
As described mechanical watch includes oscillator and control device, and wherein oscillator (being generally made up of pendulum or mechanical wheel) is with pre-
Fixed frequency repeats to swing/vibration.Described oscillator can be supplied by the weight of spring or the rope being suspended from being looped around on pulley
