Product Introduction
Ultraviolet rays can destroy the DNA or RNA structure of microorganisms, making them unable to reproduce and survive, thus 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.
Features
High durability 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 light. Some devices are also equipped with multiple mercury lamps to increase the intensity of ultraviolet radiation;
Reaction chamber
A properly designed reaction chamber ensures that the ultraviolet rays are evenly irradiated on the treated object, thus improving the treatment effect. The material used is usually a material with high ultraviolet transmittance and corrosion resistance, such as quartz glass.
Control System
Achieve precise control of equipment start, stop, running time, UV intensity and other parameters, automatic cleaning, easy operation and ensure stable operation of equipment;
Broad spectrum sterilization
Full-band ultraviolet rays can effectively kill a variety of bacteria, viruses, fungi, algae and other microorganisms, covering a wide range;
Efficient treatment of organic matter
Decompose organic pollutants in water, such as removing humus and odorous substances in water;
Quick response
Ultraviolet rays react quickly with microorganisms and organic matter, and can achieve the effects of sterilization and decomposition of organic matter in a short time;
No secondary pollution
The ultraviolet sterilization process is a physical action and will not produce secondary pollution like chemical disinfectants.
Notes: above dimension is equipment length plus width, height and accessory equipment dimension can custom-make according to practical situation, other parameter are in line with actual product.Guanyu UV sterilizer labeled with GYA is auto cleaning style, GYM is manual cleaning style, GYC means common style, GYF means frame (open channel) style.
Problems of recycling nutrient solution in soilless culture
In soilless cultivation, the recycling of nutrient solution can save water resources and fertilizers, but it also brings new problems. The recycled nutrient solution may spread root diseases, especially in high temperature and high humidity environments, where pathogens are easy to breed. Therefore, the nutrient solution must be disinfected before use to prevent the spread of diseases.
Specific application steps for medium pressure ultraviolet disinfection
Filtration
The nutrient solution needs to be filtered through a 50-70 nm filter before disinfection to remove plant debris or other particulate matter and improve the sterilization effect;
UV disinfection
Use medium-pressure UV light for disinfection, ensuring a certain dose (100mJ/cm² to kill bacteria and fungi, 250mJ/cm² to kill viruses) to ensure the disinfection effect;
Effect verification
The effectiveness of ultraviolet disinfection is affected by the transmission factor of ultraviolet rays 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.
