Ballast water treatment industry navigates 2024 challenges

Compliance drives technological evolution

The ballast water treatment industry faced an eventful year in 2024, with developments ranging from technological breakthroughs to regulatory milestones and lingering compliance challenges.

Across the globe, the maritime sector’s commitment to meeting environmental standards sparked a wave of innovation, industry collaboration, and regulatory scrutiny.

One key area of development was the introduction of new technologies aimed at enhancing the efficiency and reliability of ballast water management systems (BWMS).

Companies focused on addressing the longstanding issues of filter clogging and energy consumption. One such development was the HYCHLOR 2.0 system, which removed traditional filters to simplify maintenance and reduce space requirements.

As its developer explained, “The absence of filters not only eliminates concerns but also results in increased customer benefits by saving installation space and costs.”

Similarly, advances in ultraviolet treatment technology improved performance in challenging water conditions while reducing energy use.

The ongoing struggle with compliance

Compliance remained a central issue in 2024, with various reports underscoring the challenges shipowners face.

For example, failures during commissioning tests were reported at rates as high as 13%, with issues ranging from sediment buildup to improper installation practices.

These failures persist despite industry improvements. As one expert noted during a Riviera webinar, “Crew training is important as is correct calibration to prevent [compliance] failure.”

Regulatory disparities between regions added another layer of complexity for shipowners. In the Great Lakes region, fresh water and low salinity presented unique operational challenges.

One industry observer remarked, “No systems work consistently in the Great Lakes due to extreme conditions.”

Meanwhile, Australia implemented stricter biofouling regulations, bringing it ahead of International Maritime Organization’s progress on invasive species management.
