The series ultraviolet disinfection device is made of 304/316 stainless steel material. Internal and external polishing. Has corrosion resistance. Characteristics such as not easily deformed. The B-series ultraviolet disinfection device is equipped with a working indicator light. Power cord plug with power-off protection. Time counter and UV intensity detector (optional). The series ultraviolet disinfection device is made of 304/316 stainless steel material. Internal and external polishing. Has corrosion resistance.

The ultraviolet disinfection device for drinking water integrates comprehensive sciences such as optics, microbiology, mechanics, chemistry, electronics, and fluid mechanics. The ultraviolet disinfection device for drinking water uses a specially designed high-efficiency, high-intensity, and long-life ultraviolet UV-C light generating device to produce strong ultraviolet UV-C light that illuminates the flowing water. When bacteria, viruses, etc. in water are exposed to a certain dose of UV-C light (wavelength 253.7nm). The DNA and structure of its cells are destroyed, and cell regeneration cannot proceed, thus achieving water disinfection and purification. The spectral line with a wavelength of 185nm can also decompose organic molecules in water, generate hydrogen radicals, and oxidize organic molecules in water to carbon dioxide, achieving the goal of removing TOC.
