Ozone’s shortcomings are that the production cost is high and it is difficult to maintain the disinfection effect for a long time; in addition, even if it has been treated once, it has to be reprocessed if it is contaminated again.
오존은 생산비가 비싸고, 소독 효과를 오랫동안 유지하기 어려우며 또한 한 번 처리했더라도 다시 오염되면 재처리해야 한다는 단점이 있다.
