The core working principle of medium-pressure ultraviolet equipment is to emit ultraviolet rays covering a wide wavelength range (wavelength range 200nm~400nm), especially the UVC band (200~280nm) through a special medium-pressure mercury lamp. It can emit ultraviolet rays covering a wide wavelength, including multiple bands that have significant effects on sterilization and decomposition of organic matter.
Through ultraviolet irradiation, the DNA or RNA structure of microorganisms is destroyed, making them unable to reproduce and survive, thereby achieving efficient sterilization and disinfection. In addition, the energy of ultraviolet rays can also cause the molecular bonds of organic matter to break and decompose organic pollutants, such as removing humus and odor substances in water.
Highly durable light source system
The core is a medium-pressure mercury lamp, which has high power and wide spectrum output, and can continuously and stably emit full-band ultraviolet rays. Some equipment is also equipped with multiple mercury lamps to increase the intensity of ultraviolet radiation;
Reaction chamber
A well-designed reaction chamber ensures that ultraviolet rays are evenly irradiated on the treatment object, improving the treatment effect. Its material is usually selected from materials with high UV transmittance and corrosion resistance, such as quartz glass;
Control system
Realizes precise control of parameters such as equipment start, stop, running time, UV intensity, etc., automatic cleaning, convenient operation and ensures stable operation of the equipment;
Broad-spectrum sterilization and disinfection
Full-band UV can effectively kill a variety of bacteria, viruses, fungi, algae and other microorganisms, with a wide coverage;
Efficient treatment of organic matter
Decompose organic pollutants in water, such as removing humus and odor substances in water;
Quick response
The action process of ultraviolet rays with microorganisms and organic matter is rapid, and can achieve the effect of sterilization and decomposition of organic matter in a short time;
No secondary pollution
The ultraviolet sterilization and disinfection process is a physical action, and will not produce secondary pollution like chemical disinfectants.
In soilless cultivation, although the recycling of nutrient solution can save water resources and fertilizers, it will also bring new problems. Recycled nutrient solution may spread root diseases, especially in high temperature and high humidity environments, pathogens are easy to breed. Therefore, the nutrient solution must be disinfected before use to prevent the spread of diseases.
Filtration treatment
The nutrient solution needs to be filtered through a 50-70nm filter before disinfection to remove plant debris or other particulate matter and improve the sterilization effect;
Ultraviolet disinfection
Use medium-pressure ultraviolet light for disinfection to ensure that a certain dose (100mJ/cm² is required to kill bacteria and fungi, and 250mJ/cm² is required to kill viruses) is reached to ensure the disinfection effect;
Effect verification
The effect of ultraviolet disinfection is affected by the transmission factor of ultraviolet light in the solution. Pathogens hidden behind suspended particles may be difficult to kill, so it is necessary to ensure that the nutrient solution is fully filtered before disinfection.
