1. Ballast Water Management Plant: Global Action to Aquatic Invasive Species

    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.

2. Ballast Water Management Plant Description

    The ballast water management plant 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.
    Adopting totally chemical-free process, the Cyeco TM BWMS best suits the demand of ship by effectively avoiding the uptake or discharge of harmful organisms but generating no toxic substance to environment and human health or corrosion contribution to ballast system.
    Ballast water is treated going through the complete process (filter followed by UV reactor) at ballast water intake and re-treated at discharge through the UV reactor only (filter bypassed). The UV irradiation of ballast water again during de-ballasting ensures that any bacterial regrowth that may have occurred in the ballast tanks is fully disinfected before discharge.
3. Ballast Water Management Plant Advantages

    (1) Automatic back-flushing filter in front — a natural choice for ballast water management plant.

    The automatic self-cleaning filter serves to remove larger organisms and sediment particles, improving the transparency of water, and hence the effectiveness of UV irradiation.
    The filter is designed to automatically back-flush itself at the end of each ballasting or de-ballasting operation, and when a timer is triggered or preset differential pressure is reached.
    This automatic back-flushing mechanism keeps the filter screen clean and provides reliable, non-stop operation at high sediment loads. All organisms and particles removed by the filter are continuously returned to the sea at ballasting site. The filter is bypassed during the de-ballasting operation.
    (2) UV disinfection — easiest and most reliable solution for ballast water management plant.

    The device adopts medium pressure ultraviolet (UV) as a means of disinfection. Unlike chemical disinfectant, this purely physical disinfection process uses nothing but UV light to deactivate or damage the DNA of organisms, killing them or making reproduction impossible without any side effect.
    The medium pressure lamps that our device utilizes produce polychromatic UV output across the entire spectrum of germicidal curve. Taking into account the various poor water quality challenges at high flow rates, the powerful medium pressure lamps are regarded as a better solution for ballast water treatment application rather than low pressure lamps.
    The medium pressure lamps are installed to be oriented perpendicular to fluid flow, which results in high performance and compact size for easy installation.
   (3) Control panel  completely automatic control

    The entire ballast water management plant is controlled by a PLC (programmable logic controller) control panel with in-touch screen mounted on it. The PLC system monitors and controls all components (filter, UV, automatic valves, if required) and keeps the UV unit running at optimal status.
    All operations and indications can be viewed on in-touch screen and the system can be easily integrated into ship control system to allow for operation and monitoring in control room.
