Market Analysis and Customer Cases of Wastewater Treatment Equipment and Waste Gas Treatment Equipment in South America

South America is experiencing accelerated industrial growth, urbanization, and stricter environmental regulations, creating substantial market opportunities for advanced wastewater treatment equipment and exhaust gas treatment systems(including scrubbers, flue-gas desulfurization units, and VOC/NOx controls). Governments across the region are prioritizing pollution reduction to address water scarcity, river contamination, and urban air quality issues, while industries such as mining, oil & gas, and manufacturing seek compliant, energy-efficient solutions. Exporters of membrane bioreactors, activated sludge systems, biological treatment units, scrubbers, and particulate filters stand to benefit significantly.

Wastewater Treatment Market: Strong Growth Driven by Urbanization and Regulations

The Latin America water and wastewater treatment market is projected to reach USD 48.12 billion by 2032, growing at a CAGR of 5.9% from 2025–2032, with the wastewater segment accounting for 61.1% of the share in 2025. Brazil leads with 36.7% of the regional market, fueled by rapid industrialization and mandates for universal sanitation coverage.

Key drivers include:

• Low wastewater treatment rates in many countries (e.g., only partial coverage in parts of Peru and Argentina).

• Industrial demand from mining (Chile/Peru), agriculture, and manufacturing.

• Water scarcity in arid zones and rising public health concerns over water-borne diseases.

The equipment segment (filtration, disinfection, biological treatment) is expected to grow at a CAGR of around 5.1–5.4% through 2033, with municipal applications dominating but industrial uses expanding fastest.

Recent Wastewater Treatment Cases Highlighting Equipment Needs

• Peru (October 2025): The government launched a USD 200 million World Bank-funded 10-year program to modernize wastewater management, promote circular economy practices (reuse and sludge valorization), and expand treatment capacity across multiple regions. This directly boosts demand for advanced biological reactors, membrane systems, and sludge dewatering equipment.

• Chile (2025): Sacyr Water secured a major public-private partnership for the region’s largest wastewater reuse plant in Antofagasta. The facility treats municipal sewage for industrial and agricultural reuse, incorporating tertiary treatment and desalination integration to combat severe drought.

• Brazil (2025 onward): Upcoming concession tenders for water and sewerage services, combined with the national mandate for universal sanitation by 2033, are driving billions in investments. States like São Paulo and Rio de Janeiro are upgrading facilities with energy-efficient aeration and disinfection technologies.

Exhaust Gas Treatment Market: Tightening Air Quality Rules Fuel Industrial Demand

While specific South American data is emerging, the global air pollution control equipment market (including exhaust gas systems) is expanding at 5.3% CAGR through 2034, with Latin America as a high-growth emerging region. Mining smelters, oil refineries, and power plants require scrubbers, electrostatic precipitators, and selective catalytic reduction (SCR) units to control SO₂, NOx, particulates, and VOCs.

Regional drivers:

• Adoption of the Regional Action Plan on Air Quality 2026–2029.

• Mining “sacrifice zones” in Chile prompting lawsuits and stricter permits.

• Oil & gas methane regulations (e.g., Colombia’s pioneering rules) and refinery upgrades for low-sulfur fuels.

Industrial flue-gas desulfurization (FGD) scrubber system — essential equipment for mining smelters and refineries to remove SO₂ and particulates from exhaust gases.

Recent Exhaust Gas Treatment Cases

• Chile Mining Sector (2025): Major copper producers like Codelco and Anglo American face legal pressure over air pollution in saturated zones (e.g., Calama and Quillota). Companies are retrofitting smelters with flue-gas treatment plants; Anglo American reported an 18% reduction in particulate matter through upgraded scrubbers and filters. New environmental approvals for expansions now mandate state-of-the-art exhaust controls.

• Brazil Refineries (2025–2029): Petrobras is investing billions in the Abreu e Lima (RNEST) refinery’s second train to produce S10 low-sulfur diesel, replacing high-emission fuels and reducing NOx/SOx output. Similar upgrades at other facilities drive demand for catalytic converters and VOC recovery systems.

• Colombia: As the first South American country to regulate methane from oil & gas, operators are installing capture and treatment equipment, creating new opportunities for flare gas recovery and exhaust abatement systems.
