Introduction of Litopenaeus vannamei
White shrimp,Litopenaeus vannamei is one of the three largest shrimp varieties in the world, which can grow in the wide range of salt concentration,temperature and bad environment.Fast growth rate and short farming cycle are its main characteristics.Litopenaeus vannamei was widely cultured in China since 2001.With bad climatic condition and water quality,infectious diseases occurred frequently and spread quickly,so the mortality rate increased.Infectious diseases include virus disease,bacterial disease and parasitic disease.Virus disease contains White spot syndrome, Taura syndrome,Yellow head disease,Infectious hypodermal,Hematopoietic necrosis and Hepatopancreatic parvovirus.Bacterial disease contains vibrio,eye-rot,gill-rot and enteritis. Parasitic disease contains ciliate and yellow gill. The occurrence of disease will not only bring loss to the farmers but also make water self-purification capacity be out of control during the treatment process.
Changzhou Peide Water Treatment Equipment Co.Ltd supplies UV sterilizer, medium pressure UV disinfection system,open channel UV sterilizer and aquaculture UV sterilizer for fish farming. This chapter focuses on the usage of medium pressure UV disinfection system for Litopenaeus vannamei.

Quality Assurance of Medium pressure UV disinfection system for Litopenaeus vannamei
1.High illumination maintenance
The suppliers of Medium pressure UV disinfection system are all foreigners.No factory can produce medium pressure UV lamp that is stable and long-term applied to water treatment in China.Medium pressure UV lamp of Peide has unique advantages in foreign products.Firstly,Peide has unique design of lamp.It uses new technology that make sure the transmittance and prevent lamp black,which makes it long service life.The illumination of Peide medium pressure UV lamps is well maintained at 82.6%.
2.Long service life of lamp
Medium pressure UV disinfection system adjust the power output according to the water quality and water flow rate.Common medium uv lamp inner glass is easy to get black when adjust the power output which will affect the life time of lamp and the disinfection efficiency. Medium pressure UV lamp of Peide can solve the problem perfectly,which save energy cost a lot.
3.Electronic ballast with high quality
Low frequency electronic ballast of Peide has unique advantages.Not only it has high stability but also saves energy cost.The power conversion rate is above 90%.
