1. The Importance of Ballast Water Management

    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 transfer of ballast water cannot be avoided since ballast water is absolutely essential to the safe and efficient operation of modern shipping. But the transportation of non-native species can be eliminated by means of appropriate treatment of ballast water.
    The International Maritime Organization (IMO) has adapted the International Convention for the Control and Management of Ship’s Ballast Water and Sediments, 2004, which mandates all ships that carry ballast water install treatment system by the required year depending on their ballast tank capacity and the year being built.

3. Ballast Water Management Principle Introduction

    The treatment procedure includes three major parts: Filtration, Seawater Electro-chlorination for disinfection and Neutralization.
    (1) Filtration: during ballasting, total volume of ballast water flow through a 50um filtration unit, marine organism and particles larger than 50um are filtrated and discharged back to local water;
    (2) Seawater Electro-chlorination for disinfection: a small amount of filtrated sea water flows into electrolysis unit to generate high concentrated sodium hypochlorite solution, which will be injected back to main ballast pipe line after de-gas treatment. Sodium Hypochlorite solution will be mixed with the sea water form main ballast pipe line to a certain designed concentration, which is able to kill the marine organism including spores, lavas and pathogen within the water, in order to meet the disinfection standard (D-2 Standard and the others). The concentration of active agent in main pipe line is monitored and controlled through TRO unit and system main control unit.
    (3) Neutralization: during vessel de-ballasting, when the residual chlorine concentration is lower than IMO requirement, Neutralization Unit will not be operating; If the residual chlorine concentration is higher than the requirement, Neutralization Unit is automatically dosing Neutralization agent in water stream. The dosing concentration is monitored and controlled automatically through TRO Unit and System Control Unit.
