When elapsed 2.0x10 ¹ 99.3 * CFU: Colony For Minute Unit
* Used strain: E. coli (E.coli KCCM 12515)
* Test environment: 22.0℃

In Table 2, CFU is an abbreviation of (Colony For Minute Unit, colony forming unit), and means one of the number of bacteria units.

In general, bacteria are fine in size, so it is impossible to identify one bacteria with a human eye. Therefore, in order to display the number of bacteria, first, the bacteria are cultured using a plate medium, and the number of bacterial colonies contained in 1 mL of raw water is counted and displayed in units of CFU/mL.

In addition, the test method used in Experimental Example 1 is'Method for measuring the number of E. coli: Total E. coli group of the water pollution process test standard-variant of the plate colony method', and the used strain is E. coli (E. coli KCCM 12515).

In addition, the number of bacteria refers to the number of colonies of bacteria contained in 1 mL of raw water.

Referring to Table 2, before the start of the test, the number of bacteria contained in the raw water is 2.7x10 ³ CFU/mL.

And, if 15 minutes have passed since the start of the test, the number of bacteria contained in the purified water that has passed through the integrated sterilization/filtration filter is 7.2x10 ² CFU/mL, so the bacteria reduction rate of the purified water is 73.3% [(2700-720)/2700 ]to be.

And, if 30 minutes have elapsed since the start of the test, the number of bacteria contained in the purified water is 3.0x10 ¹ CFU/mL, so the bacterial reduction rate of the purified water is 98.9% [(2700-30)/2700].

And, if 60 minutes have elapsed from the start of the test, the number of bacteria contained in the purified water that passed through the integrated sterilization/filtration filter is 2.0x10 ¹ CFU/mL, and the bacteria reduction rate of the purified water is 99.3% [(2700-20)/2700 ]to be.

In the water purifier for companion animals using the antibacterial ball according to the present invention, raw water of 1,000 mL or more can be accommodated. However, in this antibacterial test, the test was conducted using 800 mL of raw water.

In the water purifier for companion animals according to the present invention, the flow rate of the pump is 2,500 mL/min, the apparent volume occupied by a plurality of antibacterial balls having a diameter of 5 mm and a weight of 120 g is 60 mL, and an empty space between the plurality of antibacterial balls through which raw water passes. The total pore volume is 25 mL.

And, in order to sterilize raw water having a total volume of 800 mmL with an efficiency of 99.9% or more in the water purifier, it must contact a plurality of antibacterial balls for at least 10 minutes.

When raw water with a volume of 25 mL passes through the integrated sterilization/filtration filter inside the water purifier once, it contacts a number of antibacterial balls for 0.6 seconds [(25 mL×60 seconds) ÷ 2500 mL].

And, in order for raw water with a volume of 25 mL to contact a number of antibacterial balls for 10 minutes inside the water purifier, the area in which the plurality of antibacterial balls are accommodated is 1,000 times [(10 min ÷ 0.6 sec/time) = (600 sec ÷ 0.6 sec /Time)] You have to cycle.

At this time, in order for raw water with a total volume of 800 mL to contact multiple antibacterial balls for 0.6 seconds (0.01 minutes), the water purifier for companion animals using the antibacterial balls must be operated for 19.2 seconds [(800mL/25mL)×0.6 seconds].

Therefore, in order to contact the raw water with a total volume of 800 mL with a number of antibacterial balls for 10 minutes (600 seconds), the water purifier for companion animals using the antibacterial ball is 5 hours and 20 minutes [600 seconds / 0.6 seconds × 19.2 seconds = 19,200 seconds] Should work while.

If the operating time of the pet water purifier using the antibacterial ball has elapsed for 15 minutes, the raw water with a total volume of 800mmL is about 28 seconds ((15 minutes/320 minutes) × 10 minutes × 60 seconds) with a number of antibacterial balls inside the water purifier. /Min=28.125 seconds].

In addition, if the operating time of the pet water purifier using the antibacterial ball has elapsed for 30 minutes, the raw water with a total volume of 800mmL is about 56 seconds [(30 minutes/320 minutes) × 10 minutes × 60 seconds/minute = 56.25 seconds].

In addition, when the operating time of the water purifier for companion animals using the antibacterial ball is 60 minutes, raw water with a total volume of 800mmL is about 1 minute 52 seconds with a number of antibacterial balls inside the water purifier [60 minutes/320 minutes × 10 minutes × 60 seconds/minute = 112.5 seconds].

Referring to Table 2, when 60 minutes have elapsed from the start of the test, the time when raw water having a total volume of 800 mL is in contact with the plurality of antibacterial balls is about 1 minute 52 seconds, and at this time, the bacterial reduction rate of the purified water is 99.3%.

Therefore, after 5 hours and 20 minutes from the start of the test, raw water having a total volume of 800 mL is in contact with a number of antibacterial balls for 10 minutes, resulting in a bacterial reduction rate of 99.9% or more.

A: initial number of bacteria in the control group

B: Number of bacteria in the test group after a certain period of time

Referring to Table 3, before the start of the test, the initial number of bacteria contained in the raw water of the control group is 3.0 × 10 ³ CFU / mL.

And, if 10 minutes have passed since the start of the test, the number of bacteria in the test group is 10 Since it is CFU/mL, at this time, the bacterial reduction rate of the integer is 99.7%[(3000-10)/3000].

Thus, a number of antibacterial balls can be sterilized by 99.7% or more of Legionella bacteria by contacting raw water with a number of bacteria of 3.0×10 ³ CFU/mL for 10 minutes.

Experimental example 3: Antibacterial ball Staphylococcus sterilization test by

From May 9, 2018 to May 11, 2018, the Korea Institute of Machinery, Electrical and Electronic Tests conducted a staphylococcal sterilization test with an antibacterial ball for the purpose of quality control.

One. Sample name

1) The sample used in the Staphylococcus aureus sterilization test with an antibacterial ball is a number of antibacterial balls (150±1)g with a diameter of 10mm coated with silver iodide in a film form.

2. Test method

1) Preparation of strain: Dilute staphylococcus aureus (ATCC 6538) to about 5.0×10 ³ CFU/mL and use it as an inoculum.

2) Put 150g of sample in 200mL glassware and mix with 45mL of test bacteria solution. At this time, the control bacteria are tested as having no sample.

3) Close the lid of the sample and react in a shaking incubator at 200 rev/min for 20 minutes.

4) After 10 minutes, the strains of the test group and the control group are collected and diluted appropriately.

5) Add 1 mL of diluted solution to Petri dish, mix evenly with TSA to harden, and cover with TSA on the hardened medium to prevent proliferation.

6) After culturing for 24 hours, count the number of colonies to check the number of bacteria.

7) The bacterial reduction rate is calculated using the following equation.

Bacterial reduction rate (%) = {(A-B)/A}×100

A: initial number of bacteria in the control group

B: Number of bacteria in the test group after a certain period of time

3. Test equipment

1) The test equipment used in the Staphylococcus aureus sterilization test with an antibacterial ball is an incubator with device number KTC-17-178.

4. Test result

Table 4 shows the results of the Staphylococcus aureus sterilization test by antibacterial balls.

(ATCC 6538) Control 4.7×10 ⁴ 4.7×10 ⁴ - Test group 4.4×10 99.91

Referring to Table 4, before the start of the test, the initial number of bacteria contained in the raw water of the control group is 4.7×10 ⁴ CFU/mL.

And, after contacting the test group with a plurality of antibacterial balls for 20 minutes, the number of bacteria contained in the purified water was 44 Since it is CFU/mL, the bacterial reduction rate of the purified water at this time is 99.91%[(47,000-44)/47,000].

Therefore, a number of antibacterial balls can be sterilized by 99.91% or more of Legionella bacteria by contacting raw water with a number of bacteria of 4.7×10 ⁴ CFU/mL for 20 minutes.
