Medium Pressure UV Sterilizer Disinfection System
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.
