Ballast Water Treatment Market Size, Share & Industry Analysis, By Treatment Type (UV Treatment, Filtration, Solid-Liquid Separation, Chemical Disinfection, Others), By Ship Type (Container Ship, Bulk Carrier, Oil Tanker, Cargo Ship, Others) And Regional Forecast, 2026-2034

The global ballast water treatment market size was valued at USD 7.66 billion in 2025. The market is projected to grow from USD 8.33 billion in 2026 to USD 16.26 billion by 2034, exhibiting a CAGR of 8.72% during the forecast period. 

Ballast water treatment is a system that consists of freshwater or saltwater, which is shrouded in the ballast tank of ships focused on protecting the marine organism. Ballast water provides maneuverability draft and stability to cargo ships during the rough seas or when the ships are not carrying enough heavy loads or cargo. The ballast water market has a progressing technology with a growing manufacturer in the industry.

Based on treatment type, the market is segmented into UV treatment, filtration, chemical disinfection, solid-liquid separation, and others. The solid-liquid separation helps separate the solid suspension of solid materials from the ballast water and is highly effective for various organisms. The separation is done by sedimentation or by surface filtration process where the solid materials settle out by their weight and are effective against many organisms’ type and sediments. Based on these factors, the solid-state separation is expected to dominate the market segment.

Based on the ship type, the market is segmented into general cargo, bulk carriers, oil tankers, container ships, cargo, and others. The oil tankers are anticipated to dominate the market segment owing to the transportation of large quantities of LPG, crude oil across various locations through the ocean. With the increasing oil demand and nature of trade, sometimes oil tankers run with empty tanks. Onboard the ballast water treatment is essential for safety during the empty runs, directly impacting the ballast water treatment market.

One of the major drivers for the global ballast water treatment market is the growing volume of the shipping industry. Other than that, for protecting the marine environment the government has implemented initiatives along with International Maritime Organization (IMO) which anticipated growing the global ballast water treatment.

The storage allocations generated due to by-products after the ballast water treatment acts as the major restraints. Other than that, the initial cost associated with the installation of ballast water treatment hinders the market growth.

Key Market Driver -

The regulation for mandatory installation of ballast water treatment on ships lead by International Maritime Organization (IMO) drives the global ballast water treatment market.

Key Market Restraint -

The storage capacities held by the generation ballast water treatment byproducts hinders the ballast water treatment market.

Key players covered:

Some of the major companies present in the global ballast water treatment market are Trojan Marinex, Xylem Inc., Norwegian Greentech, Evoqua Water Technologies LLC, Ecochlor Inc., Calgon Carbon Corporation, Veolia Environment, Alfa Laval AB, Hyde Marine, Mitsubishi Heavy Industry, Optimarin AS, Heraeus, LightSources, Mareno Tech, NEI Treatment, Damen Shipyards Group, and MH Systems Inc.

Regional analysis:

The ballast water treatment market has been studied across North America, Europe, Asia Pacific, Latin America, the Middle East & Africa. The Asia Pacific is expected to dominate the market in terms of volume of ports and harbors leading to the automotive industry and electronics trading; other than that, the IMO has made mandatory guidelines for installing ballast water treatment which is anticipated to create the need for ballast water treatment in ships across the region. Following the Asia Pacific, North America and Europe have made regulatory laws for environment protection. The rising concern for protecting the marine environment is expected to drive the ballast water treatment market across the region. In the Middle East & Africa, the ballast water treatment market has been driven by the growing investments in shipyards and canals for transportation and trading through cargo ships and others; this has led to the increasing number of ships and boosted the ballast water treatment market.
