Secondary Water And Wastewater Treatment Equipment Market is Expected to grow at a robust CAGR of 4.77% through 2030F

The increasing global secondary water and wastewater treatment equipment market is driven by growing adoption of membrane bioreactor (MBR) Systems, increasing emphasis on water reuse and circular economy during the forecast period 2026-2030F.

According to TechSci Research report, “Secondary Water And Wastewater Treatment Equipment Market – Global Industry Size, Share, Trends, Competition Forecast & Opportunities, 2020-2030F”, The Global Secondary Water And Wastewater Treatment Equipment Market was valued at USD 24.64 Billion in 2024 and is expected to reach USD 32.88 Billion by 2030 with a CAGR of 4.77% during the forecast period. One of the most significant trends in the secondary water and wastewater treatment equipment market is the widespread adoption of Membrane Bioreactor (MBR) systems. MBR technology combines conventional biological treatment with membrane filtration, offering superior effluent quality and a smaller footprint compared to traditional secondary treatment methods. This has made it particularly attractive for both municipal and industrial users facing space constraints and stringent discharge norms.

The global demand for MBR systems is increasing due to their ability to remove suspended solids and pathogens more effectively than conventional activated sludge processes. Industries such as pharmaceuticals, chemicals, and food and beverages are adopting MBRs to comply with stricter environmental regulations and to enable water reuse.

Additionally, MBR systems offer scalability, modularity, and automation compatibility, which enhances their operational efficiency and reduces manual intervention. Advanced MBR configurations with energy-efficient membranes and automated control systems are driving further adoption. For example, the latest submerged hollow fiber membrane modules offer longer life and reduced fouling, thereby decreasing maintenance needs.

With urban areas expanding and centralized wastewater treatment infrastructure under pressure, decentralized MBR-based systems are being implemented in housing colonies, commercial complexes, and hospitals. This trend is also supported by government incentives in several countries for compact and efficient treatment technologies.

Based on Equipment Type, Filtration Equipment is the fastest growing segment in the global Secondary Water And Wastewater Treatment Equipment market during the forecast period, due to increasing demand for higher quality effluent and stricter discharge regulations. As industrial activities expand and urban populations grow, the need to treat wastewater to safer, reusable levels has intensified. Filtration systems—such as sand filters, membrane filters, and disk filters—are highly effective at removing suspended solids, organic matter, and pathogens after primary treatment, making them an essential part of secondary treatment processes.

Governments and environmental bodies around the world are tightening wastewater discharge norms. For example, many countries now mandate tertiary-level treatment before discharging effluent into water bodies, pushing industries and municipalities to upgrade their secondary systems to include high-efficiency filtration. Moreover, as industries like pharmaceuticals, food & beverage, and chemicals generate wastewater with complex compositions, conventional treatment methods are insufficient, boosting the need for advanced filtration systems capable of handling high contaminant loads.

The rapid development and deployment of membrane technologies such as membrane bioreactors (MBRs) have also contributed to this growth. These systems combine biological treatment and membrane filtration, offering superior performance and compact design—ideal for space-constrained urban areas. Additionally, the falling cost of membrane manufacturing and improvements in durability and efficiency are making these solutions more accessible across both developed and developing regions. Filtration systems also support water reuse initiatives, which are gaining traction globally due to increasing water scarcity. In the Asia Pacific region, particularly in countries like India and China, governments are investing heavily in decentralized wastewater treatment and reuse projects that rely on efficient filtration equipment.

Based on region, Asia Pacific is the fastest growing region in the Global Secondary Water And Wastewater Treatment Equipment Market during the forecast period due to rapid industrialization, urban expansion, and increasing environmental awareness. Countries such as China, India, Indonesia, and Vietnam are witnessing unprecedented economic growth, leading to a surge in both municipal and industrial wastewater volumes. This trend is driving strong demand for advanced secondary treatment systems capable of meeting tightening regulatory standards and supporting water reuse initiatives.

Governments in the region are implementing stringent regulations to combat water pollution and ensure public health. For instance, China’s “Water Ten Plan” mandates stricter discharge norms, while India’s “Namami Gange” mission prioritizes advanced sewage and effluent treatment infrastructure. These national-level programs are significantly boosting investment in secondary water and wastewater treatment technologies, including aeration systems, clarifiers, and membrane filtration units.

Moreover, water scarcity in many parts of the region has accelerated the need for wastewater recycling and reuse, especially in agriculture and industry. According to the Asian Development Bank, over 80% of wastewater in developing Asia is discharged untreated—highlighting a huge opportunity for infrastructure development and equipment deployment.

Private sector participation and foreign direct investments are also playing key roles in this growth. International players are forming joint ventures with regional firms to introduce modern, energy-efficient equipment into local markets. Additionally, megacities like Jakarta, Manila, and Bangkok are investing in centralized wastewater treatment facilities to manage increasing waste volumes sustainably. Rising public awareness, improved funding mechanisms, and a shift toward decentralized treatment in rural and peri-urban areas further enhance the region’s growth prospects. Collectively, these factors position Asia Pacific as the fastest growing region in the market, fueled by urgent needs, regulatory pressure, and a growing commitment to sustainable water management practices.
