Ballast Water Treatment Market Report 2026

The ballast water treatment market size has grown exponentially in recent years. It will grow from $139.67 billion in 2025 to $184.87 billion in 2026 at a compound annual growth rate (CAGR) of 32.4%. The growth in the historic period can be attributed to implementation of imo ballast water management convention, rising international maritime traffic, adoption of physical and chemical treatment methods, advancements in filtration and disinfection technologies, increasing environmental regulations for marine ecosystems.

The ballast water treatment market size is expected to see exponential growth in the next few years. It will grow to $502.95 billion in 2030 at a compound annual growth rate (CAGR) of 28.4%. The growth in the forecast period can be attributed to rising investments in eco-friendly ballast water treatment technologies, integration of smart monitoring and control systems, growing demand for retrofitting older vessels, expansion of global shipping fleet, development of hybrid treatment methods combining physical and chemical processes. Major trends in the forecast period include adoption of advanced uv and filtration technologies, integration of automated ballast monitoring systems, expansion of chemical treatment solutions for ballast water, growing focus on compliance with imo d-2 standards, increasing demand for energy-efficient ballast water treatment systems.

The growth of the shipping industry is expected to drive the expansion of the ballast water treatment market in the coming years. Shipping involves the transportation of goods, commodities, or cargo from one location to another, typically across bodies of water. It plays a crucial role in international trade, facilitating the movement of goods between countries and continents. As global trade continues to expand, the number of vessels operating in different regions also rises, increasing the risk of invasive species and aquatic organisms being introduced through ballast water. For example, in April 2024, a State of the Cruise Industry report by the Cruise Lines International Association (CLIA), a US-based cruise trade association, revealed that an estimated 31.7 million cruise ships carried passengers in 2023, representing a 7% increase over the previous four years. Consequently, the rise in shipping activity is fueling the growth of the ballast water treatment market.

Major companies operating in the ballast water treatment market are concentrating on the development of innovative technologies, such as advanced filtration and UV systems, to improve efficiency and address growing regulatory and environmental requirements. Advanced filtration and UV systems refer to technologies that eliminate impurities and microorganisms from ballast water through the use of fine filtration and ultraviolet light, ensuring environmentally safe and compliant water discharge. For instance, in October 2023, BIO-UV Group, a UK-based manufacturer of water purification and disinfection systems, introduced the BIO-SEA L01-0030 Mini, recognized as the smallest UV-based ballast water treatment system available in the market, aimed at operators of workboats, yachts, research vessels, and offshore support vessels. The company developed this fully automated system to combine filtration and UV treatment for ballast water flow rates ranging from 13 m³/h to 30 m³/h, featuring a compact skid footprint of only 1 m², thereby offering an efficient solution to meet the growing demand for ballast water treatment technologies.

In April 2024, Optimarin AS, a Norwegian manufacturer of ballast water treatment systems, acquired the Hyde Marine brand from Italy’s De Nora for an undisclosed amount. This acquisition aims to strengthen Optimarin’s ballast water management capabilities, allowing the company to offer more advanced treatment solutions and improve compliance with environmental regulations, positioning itself for long-term growth in the competitive maritime industry. Hyde Marine, Inc. is an Italy-based manufacturer of ballast water treatment systems (BWTS) designed to prevent the spread of non-native aquatic species.
