New Crown does not advocate UV for the following reasons:
First of all, because UV disinfection has greater limitations, it is not recommended as a means of routine disinfection in the home. Ultraviolet light is light, once there is a cover and blocking the effect immediately greatly reduced, and the family furniture and too many gaps, UV light can not get in, naturally, the effect of disinfection.
Secondly, the traditional UV lamps generally disinfection time to half an hour, although these years there are some new developments in UV technology, but have not yet seen a systematic, authoritative research or reports that prove that 0.3 seconds can be achieved disinfection. In the field disinfection, because the environment temperature is different, the degree of contamination is different, if you use such a short disinfection time to do disinfection, disinfection effect is very difficult to guarantee.
Moreover, ultraviolet light itself has too much energy, if people do not have professional protection measures to irradiate, it will have certain side effects on the human body. When people's exposed epidermis is directly irradiated by ultraviolet lamps, there will be redness, swelling, itching, and flaking symptoms, and the more serious patients may even develop cancer and skin tumors.
Ultraviolet disinfection
Ultraviolet disinfection is the use of appropriate wavelengths of ultraviolet light can destroy the microbial organism cell DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the molecular structure, resulting in the growth of the cell death and/or regeneration of the cell death, to achieve the effect of sterilization.
Ultraviolet disinfection technology is based on modern epidemiology, medicine and photodynamics, the use of specially designed high-efficiency, high-intensity and long-life UVC-band ultraviolet irradiation of flowing water, the water will be a variety of bacteria, viruses, parasites, algae, and other pathogens directly killed.
