Invasive Species: A Global Concern Ships transport over 80% of the world’s commodities, and transfer 3 to 5 billion tons of ballast water annually between oceans, all the while ballasting and discharging water during operation. Ballast water contains many marine organisms, larvae, eggs, plankton… that, when introduced into a new environment, may survive and invade the local marine ecological system. It has been estimated that more than 7000 species are transported each day through ballast tanks, and that some 40 recent invasions occurred because of ballast water discharge. The International Maritime...

The Ballast Water Management Convention The BWM Convention requires ships to develop ballast water management plans, to maintain ballast water record book, and to undertake certain measures (exchange of ballast water under D-1 rule, and treatment under D-2 standard) to control the ballast water discharges. The limits set by the D-2 regulation are presented in this table. IMO D-2 Standard For Discharge Ballast Water Microorganism category Toxicogenic Vibrio Cholerae < 10 Colony Forming Unit / 100 mL Escherichia Coli < 250 Colony Forming Unit / 100 mL Intestinal Enterococci < 100 Colony Forming...

BALLAST TANK UV TREATMENT BALLASTING: Filtration + UV disinfection When the pressure gauge indicates clogging of the filter, the self-cleaning cycle is automatically launched. The dedicated backwash pump ensures the discharge of the filtrate, without loss of flow rate while filling the ballast tanks. BALLAST TANK UV TREATMENT DEBALLASTING: UV disinfection only - filtration is automatically by-passed. CLEANING: At the end of operation (either ballasting or deballasting) a total purge of the system is performed, followed by flushing and filling of the filter and UV reactors with fresh water. Well...
