200 m³ Ships UV Ballast System
Application
BWMS is a key international measurement for environmental protection that aims to stop the spread of potential invasive aquatic species in ships' ballast water enters into force. Being a relatively more mature disinfection technology, compared to other disinfection technologies, ultraviolet disinfection does not produce active substances, does not pose an occupational hazard to crew, more economical and environmentally friendly.

System Operating Principles
In the ballast process of the ship, the ballast water enters the ballast water management system from the ballast pump through the filter, then is treated by the MPUV (medium pressure Ultraviolet) reactor, and then enters the ballast tank. Through the filter; large inorganic particles, most zooplankton and phytoplankton will be removed to ensure the effectiveness of downstream MPUV disinfection. Ultraviolet irradiation at 200-280nm wavelength in MPUV reactor can cause damage to cells and realize disinfection of residual plankton, bacteria and viruses in ballast water.
During de-ballasting, the ballast water is directly pumped into the MPUV reactor; by passing the Filter for secondary disinfection treatment before discharge.
