Disinfection methods and principles

A, water treatment and disinfection methods

Ultraviolet sterilizer it is a kind of water treatment equipment through the ultraviolet germicidal lamp on the water flow in the pipeline sterilization. Ultraviolet light is a high-energy electromagnetic waves, especially in the wavelength of 254 nanometers of ultraviolet light has a strong sterilization effect. When a certain intensity of ultraviolet irradiation of living organisms, the instantaneous high energy will make the biological DNA strand break and become inactive.

Two, ultraviolet sterilizer sterilization principle

Use of appropriate wavelengths of ultraviolet light can destroy the microbial organism cell DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) of the molecular structure of the cell, resulting in the growth of cell death and/or regenerative 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.

Three, ultraviolet sterilizer features

Fast sterilization, high efficiency: can be achieved in a few seconds chlorine disinfection dozens or tens of minutes disinfection effect.

Large sterilization range: almost all viruses, bacteria in a sufficient amount of ultraviolet radiation dose will be killed, especially for chlorine disinfection of protozoa with tolerance.

No secondary pollution : There is no need to add other substances in the disinfection process, no harmful substances to the environment.

Small environmental impact: water temperature, pH and other conventional factors have almost no effect on the UV disinfection effect.

Installation and operation is simple: compared with other disinfection methods, the structure is simple, not highly toxic, corrosive, flammable and explosive characteristics.
