Introduction to South American White Shrimp Farming:

South American white shrimp, scientific name Litopenaeus vannamei, commonly known as white shrimp, is one of the three highest yielding shrimp species in the world. It has the characteristics of wide salinity, wide temperature, strong stress resistance, fast growth, and short breeding cycle. Since 2001, South American white shrimp has been widely promoted in China. However, due to climate conditions, deteriorating water quality, and other reasons, infectious diseases of South American white shrimp occur frequently, spread rapidly, and have a high mortality rate. Common infectious diseases include viral diseases, bacterial diseases, and parasitic diseases, among which viral diseases mainly include vitiligo syndrome, Tora virus disease, yellow head disease, infectious subcutaneous and hematopoietic organ necrosis disease, liver and pancreas parvovirus like virus disease, etc; Bacterial diseases mainly include vibriosis, eye rot disease, gill rot disease, tail rot disease, enteritis disease, etc; Parasitic diseases mainly include ciliate disease and yellow gill disease. The occurrence of these diseases not only causes significant losses to farmers, but also, in the process of treating these diseases, the use of a large amount of drugs can cause the water purification capacity to spiral out of control, affecting the balance of the ecological environment.

Peide Water Treatment Company supplies UV sterilizers, medium pressure lamp UV sterilizers, open channel UV sterilizers, aquaculture UV sterilizers, etc. This chapter focuses on introducing the medium pressure lamp UV sterilizer used for South American white shrimp farming. It is designed and produced based on the actual situation and usage environment of the South American white shrimp farming industry to meet the needs of different customers.

1. High power single lamp (400w-10000w/single), with fewer UV lamp installations, can save daily maintenance costs;

2. The all stainless steel shell is corrosion-resistant and has a long service life;

3. UV sterilization is a physical method that does not cause secondary pollution to water bodies and the surrounding environment;

4. High UV output power and strong sterilization ability;

5. Quartz sleeves have high transmittance and low energy loss;

6. The medium pressure lamp ultraviolet sterilizer used for South American white shrimp farming has a small volume, beautiful appearance, and easy and flexible installation.

Why is it necessary to use a medium pressure lamp ultraviolet sterilizer for disinfection in the cultivation of South American white shrimp

Unlike commonly used low-pressure ultraviolet lamps in China, medium pressure ultraviolet lamps can generate a wider ultraviolet spectrum and act on the entire microorganism, effectively avoiding the occurrence of photoreactivity and dark repair of DNA in microorganisms, thus having an inactivating effect on microorganisms. In addition, compared with ozone and chlorine disinfection, medium voltage ultraviolet lamp disinfection has a stronger ability to kill bacteria and decompose chemicals, with advantages such as no pollution, green environmental protection, small space occupation, easy installation, simple operation, low operating costs, and long working life.

The diseases of shrimp, especially viral diseases such as white spot syndrome virus disease, Tora virus disease, and infectious subcutaneous tissue necrosis virus disease, are the main threats to the cultivation of South American white shrimp in China, especially white spot syndrome virus disease, which currently occurs and spreads in some parts of China. In addition, shrimp diseases caused by bacteria, fungi, and other physicochemical factors are also common diseases in shrimp farming.

After using the medium pressure lamp ultraviolet sterilizer produced by Peide Water Treatment, the continuous detection of pond water quality shows that the killing rate of Vibrio is greater than or equal to 99%, the killing rate of Cymbidium is greater than or equal to 95%, and the killing rate of blue-green algae is greater than 90%. The medium pressure lamp ultraviolet sterilizer produced by Peide Water Treatment has a good control effect on diseases such as bacteria and viruses, and can ensure food safety.

Advantages of medium pressure lamp ultraviolet sterilizer for South American white shrimp farming

Quality assurance:

1. High illuminance maintenance rate

The main suppliers of medium voltage ultraviolet lamps are foreign manufacturers, and currently there are no domestic manufacturers that can produce medium voltage ultraviolet lamps with stable quality and long-term application in water treatment. Peide's medium voltage ultraviolet lamps also have unique advantages in foreign products. Firstly, Peide has its unique lamp tube design, which adopts technology to ensure the transmittance of medium voltage ultraviolet lamps and prevent blackening of lamp tube walls, resulting in a longer service life of Peide ultraviolet lamps. The illumination of Peide medium voltage ultraviolet lamps is well maintained at 82.6%.

2. High lifespan of the lamp tube

Medium voltage ultraviolet lamps often need to be adjusted for dimming based on water quality and quantity. Ordinary medium voltage ultraviolet lamps will accelerate the blackening of the lamp wall during dimming, greatly reducing the lifespan of the ultraviolet lamp and affecting its performance. Peide's medium pressure lamp effectively solves this problem, saving energy consumption, and is particularly suitable for ballast water treatment systems used in the renovation of old ships and municipal water supply systems with large changes in water supply volume.

3. High quality electronic ballasts

The low-frequency electronic ballast used by Peide Company for medium voltage ultraviolet lamps also has its unique advantages. Using electronic ballasts not only ensures high stability, but also has energy-saving effects. The original ballast designed by Peide has a power conversion efficiency of over 90%.

4. Professional design and calculation

In the design and manufacturing of medium pressure ultraviolet sterilizers for South American white shrimp farming, in addition to the selection of core products, the integration of equipment will be very important. The surface temperature of the lamp wall of medium voltage lamps can reach up to 600-800 ℃, and the selection and configuration of the sleeve have a significant impact on the lifespan and effectiveness of the lamp tube; Due to the high temperature of the lamp tube, extremely high requirements are placed on the sealing design and cooling system of the system; The control system for ballasts and lamp dimming, as well as other control systems, will be crucial for the stable operation of the system. Whether another water treatment and disinfection system can become a reliable sterilization and inactivation system requires professional UV dose calculation and verification. Peide Company has accumulated considerable experience in the application of medium voltage systems.
