Loading ballast water is the necessary method during ship sailing. When loading ballast water, organisms in seawater could be carried into ballast tanks and discharged to the destination sea area. Ballast water in ships from one sea area to another could cause the invasion of harmful aquatic organisms and pathogens. The unlimited ballast water discharging could cause serious ecological, economic and public heath impact to the receiving environment. The invasion of alien organisms had been listed by GEF as one of the four hazards to the ocean.
In order to control the invasion of harmful aquatic organisms and pathogens in ballast water effectively, the International Maritime Organization (IMO) has developed the International Convention and Management of Ship’s Ballast Water and Sediments in 2004. The convention came into force since 2009 and requires that new ships must install ballast water treatment systems and this requirement is also suitable for the existing ships. Meanwhile, the convention had set regulation D-2 which regulated the category and the quantity of the surviving organisms in treated ballast water.
1. Brightsky Electronic has the complete intellectual property right about BSKYTM BWMS such as America, European Union, Japan, Korea and China patent.2. EPT（Enhanced Physical Treatment） technology clearly show the best performance in Ballast Water Management with…
●Small volume and reasonable space ●High treatment capacity ●Good filtering effect ●Low pressure loss and flush swimmingly ●Especially suitable for atrocious sea water conditions ●Pressure difference control, time set control and manual control
The BWMS features two-stage process, applying efficient automatic filtration to remove larger organisms and sediments followed by powerful medium pressure UV unit to disinfect and inactivate smaller plankton, bacteria and pathogens.
Around the world approximately 3 to 5 billion tons of ballast water is transferred via ships each year, introducing aquatic invasive species into new environment, posing serious threats to maritime ecosystems, aquatic economy and human health….
The treating process of BWMS is mainly consisted of the following three procedures: Filtration —The ballast water is filtrated by an automatic backwashing filter with 50µm screen to remove marine organisms larger than 50µm. Disinfection —…
