    Ballast water treatment systems

     

    International Convention concerning ballast waters, was adapted in February, 2004 by International Maritime Organization (IMO, London) and requires ballast water treatment on board. The requirement for system installation on new-building ships entered into legal force in January, 2009.

    RWO-Veolia Company has elaborated a module system CleanBallast. System operation is based on the two-stage method of ballast water treatment:

    CleanBallast System of RWO-Veolia Company is easily integrated into vessel process and systems. Module design allows the installation of CleanBallast system and its components in the available area taking into consideration the arrangement of ballast system pipelines. It is very important for building of new crafts and modernization of old ones.

    System possibility 150 – 2500 m3/h (increase up to 3750 m3/h is available)

    RWO-Veolia Company, one of the first manufacturers of ballast water treatment systems in the world, has acquired a high-speed 360o 3D scanner. 

    It allows:

    Advantages of RWO-Veolia oily water treatment system:

     

      Other manufacturers RWO RWO advantages
    Type of oily water separator Closed type Suction type Suction type allows to avoid intensive mixing of source water, so, the cleaning efficiency increases. As a result, we have a longer service life of the device
    Coalescence stage Nontight installation or separator with plate coalescence filters without filtration effect Special coalescence element with additional filtration element Filtration on the first stage allows to avoid blockage of second stage and extends the service life.
    Bypass device Not included Included Second stage will be used only under extreme necessity, so the service life is extended and operation costs are considerable decreased.
    Second stage of filtration Fine coalescence device. In order to achieve the efficiency of absorber, the coalescence device on the 2nd stage is to be very “fine” (<1 µm), what will lead to inconvertible blinding in a short period of time Absorbing cartridges Absorption has a high efficiency for oily water (emulsions), so it provides good cleaning values and security (ex. in case of control by port government)
    Quality of water The most part is tested > 5 ppm, i.e. they don’t comply with class of ecological data sheet or requirements of limited access zones Tested and certified << 5 ppm High purity of treated waste water, environmental sound, green passport and requirement of limited access zones are executed. No problem with control by port government.

    WWT-LC — Hygienically safe effluent according to IMO-Standards

    The RWO-Veolia WWT-LC sewage treatment plant is a 3-chamber process. The heart of the plant is a well-established Moving-Bed Biofilm Reactor (MBBR), where organic matter is degraded into carbon dioxide and water by microbial activity. The air required for this process is generated by an integrated blower. The aeration stabilises at the same time the biomass and prevents harmful and dangerous gases from forming, such as methane and hydrogen sulphide.

    From the Bioreactor the wastewater flows into the Clarifier compartment. Here residual solids are separated by sedimentation and returned back into the Bioreactor compartment. The treated wastewater flows into the Disinfection compartment where a chlorine based disinfection chemical is added. The clean and hygienically safe water is pumped overboard via the discharge pump, controlled by level sensor in the disinfection tank. To meet the limit values set for the chlorine content, a special neutralising agent, LC35, is dosed prior to the discharge pump. This post-treatment process is a unique feature of WWT-LC making it independent from on-board water quality and keeping the pH values within limits.
