2026 Outlook for Wastewater Treatment and Waste Gas Treatment Equipment Market: Focus on Southeast Asia and South America Market

As global environmental awareness continues to rise and industrialization accelerates, the wastewater treatment and waste gas treatment equipment markets are showing strong growth momentum in 2026. According to market research reports, the global water and wastewater treatment market is projected to reach approximately USD 400.32 billion in 2026, growing at a compound annual growth rate (CAGR) of 7.5% through 2034. Similarly, the air pollution control systems market is experiencing rapid expansion, particularly in emerging economies, with Latin America expected to become one of the fastest-growing regions at a CAGR of 8.4%. As a leading supplier in the environmental protection equipment sector, our company is committed to delivering efficient and innovative solutions to meet the demands of these markets. 

In 2026, the wastewater treatment equipment solution market will benefit from water scarcity issues and increasingly stringent environmental regulations. The industrial wastewater treatment chemicals market is expected to reach around USD 166 billion, with a CAGR of 5.3%, driven primarily by industrialization and the push for sustainable development. In the waste gas treatment sector, technologies such as catalytic converters and scrubbers will continue to dominate, with the global air pollution control market growing at a CAGR of 6.3%. 

Southeast Asia Market: A Growth Engine Driven by Rapid Industrialization and Policy Support

Southeast Asia, as a core part of the Asia-Pacific market, is undergoing unprecedented industrialization and urbanization. Countries such as Indonesia, Thailand, and Vietnam, and India are vigorously promoting the adoption of wastewater and waste gas treatment equipment. In 2026, the Asia-Pacific water and wastewater treatment market is expected to account for approximately 45% of the global share, with a market value of around USD 65–180 billion in related segments, growing at some of the highest CAGRs regionally (8.43%–9.47% in key sub-sectors).

Key growth drivers include:

• Stringent Environmental Regulations: Governments across Southeast Asia are enforcing stricter wastewater discharge standards. For example, large-scale investments continue in sewage pipeline networks and treatment capacity expansions, directly boosting demand for advanced equipment such as biological treatment systems and membrane technologies.

• Industrial Expansion: Industries like textiles, pharmaceuticals, and food processing are generating surging volumes of wastewater, driving adoption of zero-liquid-discharge (ZLD) technologies and exhaust gas scrubbers.

• Water Scarcity: Population growth and climate change are exacerbating water pollution, prompting greater investment in reusable water treatment equipment.

The air pollution control equipment customized waste gas treatment solutions market in Southeast Asia is also thriving, fueled by rapid urbanization and high pollution levels that necessitate large-scale emission control deployments. For foreign trade enterprises, this represents a golden opportunity. Our company has successfully exported multiple high-efficiency wastewater treatment systems to the region, helping clients achieve compliance and sustainable operations.

South America Market: Emerging Potential and Infrastructure Investment Hotspot

South America, particularly Brazil and Argentina, is emerging as a dark horse in the wastewater and waste gas treatment equipment markets. In 2026, the Latin American water pollution control market—led by Brazil—focuses heavily on the mining and agriculture sectors. The air pollution control systems market in the region is projected to grow at a high CAGR of 8.4%, supported by expanding industrial activities and strengthened environmental enforcement. Overall, the Latin American water and wastewater treatment market is benefiting from infrastructure deficits and water scarcity, with significant expansion expected in the coming years.

Major growth drivers include:

• Mining and Agriculture Demand: Brazil's mining projects require substantial water treatment equipment to handle mining wastewater, while agricultural effluent treatment needs are also rising.

• Government Initiatives: International cooperation and domestic regulations are accelerating the adoption of clean air technologies, such as filtration systems and gas treatment equipment, to address urbanization and industrial pollution.

• Emerging Opportunities: Water scarcity is driving investments in advanced wastewater recycling technologies, with industrial applications expected to dominate.

The potential in South America is immense, especially in infrastructure development. Our company has partnered with numerous South American enterprises, providing customized waste gas treatment solutions to help them reduce emissions and improve efficiency.
