subject: Uv H2o Sterilizer Working Principle [print this page] It is in general recognized that the seven styles of light (red, yellow, orange, green, indigo, blue and purple) are created by the different wave duration with the light. Ultraviolet (UV) is also a type of light which happens to be of high energy. The wave duration of ultraviolet ranges from 40nm to 400nm, so this brief wave cannot be seen by human eyes. Ultraviolet is additional divided into ultraviolet A radiation (UVA), ultraviolet B radiation (UVB), ultraviolet C radiation (UVC) and vacuum ultraviolet radiation.
UV has robust bactericidal action and may destroy the bacteria and virus which are unhealthy for human health. The sterilization principle of UV is to destroy the DNA construction with the vital middle by irradiating the cells and virus. In this case, protein which happens to be the component of this microbe can not be formed as it used to. Then the cells or virus will die instantly or lose its reproduction capacities. Generally, UV can achieve its goal of sterilizing inside a couple of seconds. Like a make a difference of fact, all the microbes are sensitive to UV. Consequently, UV water sterilizer has outstanding qualifications in h2o therapy.
Ultraviolet water sterilizer has numerous advantages in h2o treatment, this kind of as immediate and thorough sterilizing, water high quality not affected, easy operation and reduced maintenance price.
Speed & Efficiency
The sterilizing speed of UV is much faster than that of ozone and chlorine. The sterilizing of ozone and chlorine may take ten to twenty minutes, while, high intensity UV only needs a couple of seconds. Technology of ozone and chlorine sterilizing can't kill the parasites (such as cryptosporidium and giardia) that are more dangerous for body of a human. What's worse, traditional chlorine sterilizing may even produce gano-chlorine which is carcinogenic for our well being. Ozone sterilizing may have ozone in this air which will do harm to the physical and mental health of the stuff working around. Luckily, UV is efficient to almost all of the bacteria, virus, parasites, pathogens and algae. It will not cause any secondary pollution or leave any toxic substances in the h2o.
Easy Equipment
As a consequence of its high efficiency in sterilizing, uv water sterilization has comparatively easy equipments. Once after the water flows past the UV h2o sterilizer, it can be utilized directly. The maintenance of UV h2o sterilizer can also be rather simple. The only thing we need to do is clean it periodically.
For the underlying factors mentioned above, we can see that UV water sterilizer is the most advanced, effective and economical way for h2o sterilizing. No wonder why it really is extensively applied in a great number of countries.
