Ballast Water Filtration System (BWTS)

Ballast Water Filtration System (BWTS)

The Ballast Water Filtration System (BWTS) is a cutting-edge, eco-friendly solution designed to treat ballast water onboard ships, essential for maintaining stability during their voyages. This system efficiently uses a ballast water filter to remove marine organisms, bacteria, microbes, eggs, larvae, and sediments, ensuring compliance with the International Maritime Organization (IMO) regulations. By employing physical separation techniques through water strainer baskets and possibly integrating with other treatment methods such as the Filtrex ballast water filter, the system minimizes ecological, economic, and health-related risks associated with untreated ballast water.

Technologies in Ballast Water Treatment Systems (BWTS)

  • Chemical Disinfection: Employs biocides, typically chlorine, to deactivate microorganisms. The treated water might need neutralizing before discharge, about half of all systems use this method, which often includes a ballast water treatment system filter for post-treatment clarity.
  • UV Treatment: Uses ultraviolet light to damage the DNA of organisms, stopping reproduction. Its effectiveness is linked to the quality of pre-treatment filtration and is less effective in waters with low total suspended solids (TSS).
  • Deoxygenation: Kills organisms by injecting inert gas (e.g., nitrogen) to remove oxygen, effective over 2-4 days with sealed tanks. Not suitable for short voyages.
    Heat Treatment: Eliminates organisms by heating the ballast water, either in its tanks or by passing it near the ship’s engines. Though effective, it's slow and can cause tank corrosion.
  • Ultrasonic Treatment: Applies high-energy ultrasound to destroy organisms, best when used alongside other methods like UV or biocides due to synergistic effects.
    Pulse Plasma System/Electric Pulse Method: Utilizes short, high-energy pulses to disrupt and kill organisms in the water. This method is efficient and avoids chemical use, fitting well with integrated treatment strategies.
  • Magnetic Field Treatment: Combines magnetic fields with coagulation techniques to clump together and then remove microorganisms and sediments. It’s an innovative approach, especially when used in combination with other treatment methods.

Key Advantages

  • Efficiency: Capable of filtering organisms and sediments down to sub-micron sizes, ensuring maximum effectiveness and compliance with IMO standards.
  • Equipment: Equipped with screens or discs for removing large particles, hydrocyclones for centrifugal separation, and media filters for finer particles. Water inlet strainers and bilge water filtration systems also play a crucial role. Coagulation equipment enhances the removal of smaller particles by agglomerating them into larger ones, often necessitating ballast water strainer replacement for optimal performance.
  • Automation: Fully automated system requiring minimal human intervention, primarily for supervision.
  • Maintenance: Designed for low maintenance with minimal operating costs, not requiring frequent media paper or ballast water filter replacement.

Product Applications

  • Maritime Industry: Ideal for shipping companies and vessels of all sizes to treat ballast water before discharging it back into the sea, thereby preventing the transfer of invasive species and protecting marine ecosystems.


  • Environmental Compliance: Helps ship owners and operators meet stringent international and local environmental regulations regarding ballast water management. Seawater filtration, along with the monitoring of ballast water filter cost, also supports budgeting and financial forecasting in maritime operations.

This integration of advanced technologies and system components ensures that the BWTS not only meets but exceeds the regulatory requirements for ballast water treatment, paving the way for more sustainable maritime practices.

 By preventing the transfer of invasive species and pollutants, the system plays a crucial role in protecting marine ecosystems and human health from potential threats posed by untreated ballast water.

No matter what your sea vessel needs for ballast water treatment, we have the perfect filter for you. If you have a large vessel, such as an oil or gas tanker, and need a much higher flow rate to quickly fill enormous ballast tanks, then our Ballast Water Filtration System is right for you.

The installation is straightforward, and designed to integrate seamlessly with existing ship infrastructure.

With low maintenance and operational costs, the system is a cost-effective solution for ballast water treatment. Its efficiency in filtering and treating water reduces the long-term environmental and regulatory costs for ship owners.

The system is designed for low maintenance. Routine checks and occasional cleaning of filters and screens ensure optimal performance. Our customer support provides guidance and services for any maintenance needs.
