On March 28, 2025, the national standard GB/T 45486-2025 “Ships and marine technology—Ballast water management systems (BWMS)—Computational physical modelling and calculations on scaling of UV reactors in Ballast Water Management Systems (BWMS)” was officially released by the State Administration for Market Regulation and the Standardization Administration of China. This marks China’s technical specifications in the field of ship ballast water treatment entering the globally leading ranks. The birth of this milestone standard is inseparable from the in-depth participation of Lightbest Co.,Ltd.(Lightbest) — as one of the core drafting organizations,with over a decade of accumulated ultraviolet technology experience, provided critical data support and engineering validation for the formulation of the standard, helping Chinese standards step onto the world stage.

From Standard Drafter to Industry Definer: The Technical Strength of LightbestUV

Ballast water is an important guarantee of ship navigation safety; however, untreated ballast water may carry invasive organisms and pose a serious threat to the marine ecosystem. According to the requirements of the International Maritime Organization (IMO), ships worldwide are required to fully install compliant Ballast Water Management Systems (BWMS) by 2024. As the core component of BWMS, the performance of the ultraviolet reactor directly determines treatment effectiveness and ship operational efficiency.

The newly released GB/T 45486-2025 standard, for the first time, clearly defines computational physical modelling and calculations on scaling of UV reactors from laboratory models to actual engineering applications, filling a technical gap both domestically and internationally. Relying on its profound accumulation in the field of ultraviolet disinfection, Lightbest UV completed multiple key experiments: by simulating the hydrodynamic characteristics and ultraviolet dose distribution of reactors at different scales, the reactor structural design was optimized; combined with actual ship operating conditions, a dynamic adjustment model was established to ensure a balance between treatment efficiency and energy consumption. These achievements were not only incorporated into the standard text, but also became an important reference for global shipbuilders in the design of BWMS.
