250 m³ UV Ballast Water System
Brief Indroduction
BWMS is a combined treatment system which takes advantage of filter and EPT (Enhanced Physical Treatment-UV/US) unit. It is most environmental friendly and optimally designed for all types of vessels. Adopting a pure physical treatment technology. BWMS effectively disinfects harmful aquatic organism and pathogen in water without generating any toxic substance during ballasting and de-ballasting process.

Ballasting
During ballasting process, ballast water firstly passes through a self-cleaning filter for filtration of big microorganism and particulates. The filtration of big microorganism and particulates. The filtered ballast water then passes through an EPT chamber where UV light is used to disinfect the water prior entering the ballast tank.
De-ballasting
During de-ballasting process, ballast water is pumped from the ballast tanks through the filter and EPT disinfection chamber for final treatment before being discharged overboard.
Filter Unit
During uptake ballast water passes through an automatic self-cleaning. The filter removes particulates, sediments, zooplankton and phytoplankton 50 microns. Automatic back flushing ensures and maintains filtration precision, which can achieve high working efficiency in the waters of high turbidity.
EPT Unit
UV(Ultraviolet) radiation is used to disinfect water efficiently and safely. UV technology is easy to operate and needs no potentially hazardous chemicals. US(Ultrasound) device is combined with UV radiation to penetrate cell membrane and cell wall to assist UV in destroying DNA and RNA of the microbes, affecting synthesis of enzymes and protein in the cells caused by variation, with the result of cell’s death due to abnormal metabolism.
