Water Treatment for Aquaculture Global Market Insights 2025, Analysis and Forecast to 2030, by Manufacturers, Regions, Technology, Product Type

Water Treatment for Aquaculture Market Summary

The water treatment for aquaculture market encompasses technologies and solutions designed to manage and purify water used in the farming of aquatic organisms, such as fish, shellfish, and aquatic plants, ensuring optimal conditions for growth while mitigating environmental impacts. This market is critical to addressing the challenges posed by aquaculture wastewater, which contains organic matter, nitrogen, and phosphorus primarily from residual feed and aquatic organism excretions. According to research, producing 1 kg of fish generates approximately 162 g of excretions, including 50 g of protein, 31 g of lipids, and 81 g of carbohydrates, with only about 25% of feed protein utilized by the species, leaving significant ammonia and organic nitrogen in the water. Phosphorus inputs, largely from feed (97%–98%), result in 72%–89% deposition in water bodies. Emerging contaminants, such as antibiotics like enrofloxacin, florfenicol, and sulfamethoxazole, further complicate wastewater management. Treatment technologies are categorized into physical (e.g., foam separation, membrane filtration), chemical (e.g., ozone treatment, electrochemical methods), and biological (e.g., microbial agents, constructed wetlands, ecological farming). The market is driven by global aquaculture production, which surged to 223.2 million tons in 2022, a 4.4% increase from 2020, with top producers like China (36% of global output), India, Indonesia, and Vietnam accounting for 89.8% of production. The industry faces pressures from stringent environmental regulations and the need for sustainable practices, while trends like recirculating aquaculture systems (RAS), UV disinfection, and biofiltration shape its future. Key players like Veolia, bolstered by its 2022 merger with SUEZ, and Xylem lead in innovation, addressing both commercial and environmental demands.

Market Size and Growth Forecast
The global water treatment for aquaculture market is projected to reach USD 2.5–3.0 billion by 2025, with an estimated compound annual growth rate (CAGR) of 7%–9% through 2030. This growth is propelled by rising global seafood demand, stricter environmental regulations, and advancements in water treatment technologies. The market benefits from the expansion of aquaculture operations and the increasing adoption of sustainable systems like RAS to address water scarcity and pollution concerns.
