Advanced Oxidation Processes in Water Treatment Market is Expected to grow at a robust CAGR of 4.18% through 2030F
The increasing global advanced oxidation
processes in water treatment market is driven by integration of AOPs in hybrid
and multi-barrier treatment systems, rising adoption of AOPs in industrial
wastewater reuse during the forecast period 2026-2030F.
According to TechSci Research report, “Advanced Oxidation Processes in
Water Treatment Market – Global Industry Size, Share, Trends, Competition
Forecast & Opportunities, 2020-2030F”, The Global Advanced Oxidation
Processes in Water Treatment Market was valued at USD 724.11 Million in 2024
and is expected to reach USD 934.12 Million by 2030 with a CAGR of 4.18% during
the forecast period. A key trend in the global AOP market is the integration of
AOPs into hybrid water treatment systems, combining them with biological,
membrane, adsorption, or electrochemical technologies. As water contamination
becomes more complex due to the presence of pharmaceuticals, PFAS,
microplastics, and resistant organics, standalone systems often fall short.
Hybrid systems address this by utilizing the strengths of multiple
technologies. AOPs are increasingly being paired with membrane filtration
(e.g., ultrafiltration or nanofiltration) to remove dissolved contaminants
while ensuring long-term membrane life. In municipal wastewater, AOPs are used
post-biological treatment to degrade residual micro-pollutants and antibiotics,
enhancing water safety and enabling reuse.
In industrial applications, AOPs are
integrated with biological reactors and ion exchange units to meet discharge
norms more reliably. The multi-barrier approach ensures robustness and
flexibility across varying influent conditions. For example, the combination of
UV/H₂O₂ and membrane bioreactors is
now widely used in pharmaceutical effluent treatment. Hybrid systems also help
reduce the limitations of AOPs—such as high energy use or formation of
byproducts—by balancing reaction conditions and loading rates across multiple
units. This trend is especially visible in Zero Liquid Discharge (ZLD)
applications, where AOPs act as polishing steps to minimize residual COD before
crystallization. The growing preference for customized, plug-and-play treatment
trains has further fueled this trend. Equipment manufacturers now offer modular
hybrid AOP systems with integrated controls, making them more scalable and
user-friendly. As regulatory frameworks emphasize holistic water quality and
sustainability, hybrid AOP systems are poised to become standard in
high-performance treatment facilities globally.

Based on technology, non-hydroxyl
radical-based AOPs is the fastest growing segment in the global Advanced
Oxidation Processes in Water Treatment market during the forecast period, due to their
enhanced stability, selectivity, and applicability in challenging treatment
environments. Unlike traditional AOPs that rely on hydroxyl radicals (•OH) for
pollutant degradation, non-hydroxyl radical-based systems utilize alternative
reactive species such as sulfate radicals (SO₄•⁻), superoxide anions (O₂•⁻), or singlet oxygen (¹O₂). These species exhibit higher oxidation potential in specific pH
ranges and offer better resistance to radical scavenging, particularly in
complex wastewater matrices. Sulfate radical-based AOPs (SR-AOPs), for
instance, are gaining significant attention due to their strong oxidative
power, longer lifespan in solution, and effectiveness across a wider pH range
(3–9) compared to hydroxyl radicals. They also demonstrate superior performance
in high-salinity and high-organic-load wastewaters, making them well-suited for
industrial sectors like textiles, pharmaceuticals, oil & gas, and
petrochemicals.
The growing need to treat difficult-to-degrade
contaminants such as PFAS, chlorinated solvents, and certain pharmaceuticals
has driven interest in these advanced technologies. SR-AOPs, activated using
persulfates or peroxymonosulfates and catalysts (e.g., transition metals, UV
light, or heat), are showing greater removal efficiency for such
micropollutants, contributing to their market momentum. Moreover, increasing
R&D investments, pilot-scale deployments, and favorable test results are
accelerating the commercialization of non-hydroxyl AOPs. Several startups and
technology developers are focusing on scalable, low-energy variants of these systems,
which appeal to industries seeking sustainable yet robust treatment options. With
regulatory bodies tightening discharge limits and industries facing mounting
environmental pressures, non-hydroxyl radical-based AOPs are emerging as a
next-generation solution. Their operational flexibility, targeted pollutant
removal, and potential for integration with hybrid systems position them as the
fastest-growing technology segment in the evolving AOP market landscape.
Based on region, Asia Pacific is the
fastest growing region in the Global Advanced Oxidation Processes in Water
Treatment Market during the forecast period driven by rapid industrialization,
rising water pollution levels, and increasing regulatory pressure to improve
water quality. Countries like China, India, and Southeast Asian nations are
experiencing growing demand for advanced water treatment solutions due to urban
expansion, high population density, and deteriorating freshwater resources. The
region faces severe challenges from industrial wastewater discharge,
particularly from sectors such as textiles, chemicals, pharmaceuticals, and
electronics. Many of these effluents contain persistent organic pollutants and
emerging contaminants that cannot be effectively removed by conventional
treatment methods. AOPs, with their ability to break down refractory compounds,
are increasingly being adopted in industrial zones and special economic regions
to meet discharge compliance and enable water reuse.
Governments in the region are also tightening
environmental norms. For example, China’s Water Pollution Prevention and
Control Action Plan and India’s National Mission for Clean Ganga both include
strong mandates for upgrading wastewater treatment infrastructure, including
advanced oxidation technologies. Moreover, policy shifts encouraging Zero
Liquid Discharge (ZLD) practices are creating a favorable environment for AOP
adoption in heavy industries. Additionally, the Asia Pacific region is
investing heavily in smart water infrastructure, including IoT-enabled and
automated AOP systems. Local and global players are expanding manufacturing and
R&D capacities in the region to meet rising demand, supported by government
incentives and public-private partnerships. The increasing focus on sustainability,
circular economy principles, and water reuse, especially in urban developments
and industrial clusters, further contributes to the surge in AOP installations.
With a growing awareness of water quality issues, expanding regulatory
frameworks, and rising industrial activity, Asia Pacific is poised to lead
global growth in the adoption of AOP technologies throughout the forecast
period.
