The water and wastewater treatment equipment market is segmented by application, technology, product type, and geographic regions. By application, water and wastewater treatment equipment market is divided into Industrial and Municipal. In terms of technology, water and wastewater treatment equipment market is classified into Tertiary Treatment, Secondary Treatment, and Primary Treatment. Based on product type, water and wastewater treatment equipment market is segmented into Biological, Membrane Separation, Sludge, Disinfection, and Others. Regionally, the water and wastewater treatment equipment industry is classified into North America, Latin America, Western Europe, Eastern Europe, Balkan & Baltic Countries, Russia & Belarus, Central Asia, East Asia, South Asia & Pacific, and the Middle East & Africa.
The industrial application segment is projected to account for 55.3% of the market revenue in 2025, making it the leading application area. Growth is primarily being driven by rising water consumption across sectors such as power generation, food and beverage, pharmaceuticals, and chemicals, all of which require reliable treatment solutions for both process optimization and regulatory compliance. Industrial wastewater is often highly complex, containing toxic substances, oils, and heavy metals, making advanced treatment equipment critical for ensuring safe discharge or reuse.
Companies are increasingly investing in energy-efficient and automated systems that reduce costs and improve sustainability performance. The industrial sector is also benefiting from stricter discharge regulations, which mandate compliance with stringent water quality standards, thereby boosting equipment adoption. Recycling and reuse of water within industrial plants are becoming a standard practice, further enhancing demand.
Moreover, the integration of smart monitoring tools and predictive maintenance solutions is improving operational reliability As industries continue to prioritize sustainability and efficiency, the industrial application segment is expected to maintain its leadership, supported by consistent global investments.
The tertiary treatment segment is expected to hold 40.7% of the market revenue in 2025, establishing it as the leading technology type. Growth is supported by the increasing demand for advanced purification methods that can remove residual contaminants, nutrients, and pathogens not addressed by primary and secondary treatment. Tertiary systems play a critical role in enabling water reuse for industrial processes, irrigation, and even potable applications, which aligns with global efforts to address water scarcity.
Adoption is being reinforced by stricter government regulations that require higher water quality standards for discharge into the environment. Tertiary treatment technologies such as membrane filtration, UV disinfection, and advanced oxidation processes are being increasingly deployed due to their effectiveness and efficiency. Additionally, the ability of these systems to be customized for different applications enhances their versatility.
Industrial users and municipalities are adopting tertiary systems not only to comply with regulations but also to reduce dependence on freshwater sources As water reuse becomes a central element of sustainable water management, tertiary treatment is set to remain the dominant technology in the market.
The biological product type segment is projected to capture 28.9% of the market revenue in 2025, making it a key contributor within the product category. Its growth is being fueled by the rising demand for environmentally friendly solutions that use natural processes involving microorganisms to break down organic matter. Biological treatment equipment is widely adopted due to its cost effectiveness, scalability, and ability to manage large volumes of wastewater efficiently.
Industries and municipalities favor these systems as they align with sustainability goals and offer reduced reliance on chemical-intensive processes. The segment is also gaining traction as stricter environmental regulations push organizations toward green treatment technologies that ensure compliance while minimizing ecological impact. Innovations such as advanced bioreactors, aerobic and anaerobic systems, and biofilm technologies are enhancing performance and adaptability across diverse wastewater streams.
The reduced energy footprint and operational flexibility of biological systems further add to their appeal As global initiatives increasingly prioritize sustainable water management, biological treatment equipment is expected to expand steadily and strengthen its position in the market.
Key players in water and wastewater treatment equipment market are increasing their focus towards expanding their reach in different geographies, by means of distributing their products in lucrative regions.
