Industrial Wastewater Treatment Market Report 2026

The industrial wastewater treatment market size has grown strongly in recent years. It will grow from $31.75 billion in 2025 to $33.87 billion in 2026 at a compound annual growth rate (CAGR) of 6.7%. The growth in the historic period can be attributed to rising industrial pollution levels, stringent regulatory frameworks, increasing environmental sustainability concerns, expansion of industrial production activities, early adoption of treatment technologies in key industries.

The industrial wastewater treatment market size is expected to see strong growth in the next few years. It will grow to $44.84 billion in 2030 at a compound annual growth rate (CAGR) of 7.3%. The growth in the forecast period can be attributed to growing investments in wastewater infrastructure, increasing demand for water conservation solutions, rising implementation of advanced filtration and chemical treatment, expansion of industrial modernization programs, stronger enforcement of discharge compliance regulations. Major trends in the forecast period include increasing adoption of advanced industrial effluent treatment solutions, rising focus on water reuse and resource recovery, growing emphasis on strict environmental compliance, expansion of industrial water purification infrastructure, increasing implementation of high efficiency treatment processes.

Increasing industrialization is expected to play a major role in driving the growth of the industrial wastewater treatment market in the coming years. Industrialization refers to the transition from an economy primarily based on agriculture or natural resources to one centered on mechanized manufacturing and industrial production. Industrial wastewater treatment is applied to treat and purify wastewater generated from industrial operations, which results from wet waste production and the disposal of chemical effluents across multiple industries. For example, in October 2024, data released by Eurostat, a Luxembourg-based government agency, showed that in August 2024, industrial production increased by 0.1% in the euro area and by 0.2% across the European Union compared with the same month in 2023. As a result, rising industrialization is supporting the growth of the industrial wastewater treatment market.

Key players operating in the industrial wastewater treatment market are emphasizing the development of innovative treatment technologies, including advanced organic wastewater systems, to improve purification efficiency, minimize environmental impact, and enable water and energy recovery. Advanced organic wastewater systems are high-performance treatment solutions designed to speed up the degradation of organic pollutants in industrial effluents, allowing industries to treat water more efficiently, reduce sludge generation, lower chemical and energy consumption, recover energy, decrease operating costs, and limit environmental harm. For instance, in September 2025, JSP Enviro, an India-based cleantech company, introduced the Bio-Electrochemical Anaerobic Digestor System (BEADS), an innovative solution for treating industrial organic wastewater, especially in textile and dyeing facilities. BEADS functions without electricity, requires minimal chemical usage, accelerates microbial decomposition, produces low sludge volumes, reduces treatment expenses, enables energy recovery, and lowers CO₂ emissions by around 80 tons per year for every 100-cubic-meter-per-day installation in Erode and Perundurai, Tamil Nadu. Backed by stricter environmental regulations and carbon credit incentives, the company plans to scale BEADS across industries such as food processing, pharmaceuticals, and chemicals, delivering a return on investment within 3-4 years while helping organizations meet global compliance standards, including EU carbon taxation frameworks.

In May 2023, Xylem Inc., a US-based water technology company, acquired Evoqua Water Technologies Corp. for an undisclosed value. Through this acquisition, Xylem sought to enhance and expand its global water technology platform by integrating its existing water-cycle solutions with Evoqua’s advanced treatment technologies and service capabilities. This strategic move broadened Xylem’s product and service portfolio and strengthened its capacity to address complex water and industrial wastewater treatment challenges at scale. Evoqua Water Technologies Corp. is a US-based company specializing in industrial wastewater treatment solutions.
