(MENAFN- GlobeNewsWire - Nasdaq) The global zero liquid discharge (ZLD) systems market is projected to grow from USD 9.15 billion in 2026 to USD 13.65 billion by 2031, registering an 8.3% CAGR. Growth is driven by water scarcity, stricter discharge regulations, industrial water reuse, and demand for energy-efficient hybrid ZLD systems. Pharmaceuticals are the fastest-growing end-use segment, while filtration is the second-fastest-growing process. The Middle East & Africa is a key growth region. Leading companies include Alfa Laval, Veolia, Aquatech, GEA Group, Thermax, Mitsubishi Chemical, and Andritz.Dublin, Oct. 01, 2026 (GLOBE NEWSWIRE) -- "Zero Liquid Discharge Systems Market by Process, Capacity, Application, System, End-use industry, and Region - Global Forecast to 2031" has been added to ResearchAndMarkets.com's offering.
The global zero liquid discharge (ZLD) systems market is projected to grow from USD 9.15 billion in 2026 to USD 13.65 billion by 2031, registering a compound annual growth rate of 8.3% during the forecast period. Market expansion is being supported by stringent environmental regulations, rising water scarcity, industrial water reuse requirements, and growing investment in advanced wastewater treatment infrastructure.
Hybrid ZLD systems are expected to generate significant growth opportunities because of their ability to improve water recovery while reducing energy consumption and operating costs. These systems integrate membrane technologies, including reverse osmosis, with thermal processes such as evaporation and crystallization. The combined configuration reduces the energy demand placed on thermal units, improves operating performance, and supports corporate carbon-reduction and sustainability objectives.
Industrial users in power generation, chemicals, pharmaceuticals, and electronics are increasingly adopting hybrid ZLD solutions to comply with discharge regulations and accommodate changing wastewater compositions. Flexible deployment options and advances in energy-efficient, modular technologies are expected to strengthen adoption across both established and emerging industrial markets.
Pharmaceuticals Expected to Be the Fastest-Growing End-Use Industry
The pharmaceutical industry is projected to be the fastest-growing ZLD systems market segment by value through 2031. Pharmaceutical manufacturing generates high-strength wastewater containing active pharmaceutical ingredients, solvents, and organic compounds. Regulatory scrutiny of effluent discharge, antibiotic pollution, and chemical contamination is encouraging manufacturers to invest in advanced wastewater treatment and ZLD technologies.
Demand is also increasing as pharmaceutical production capacity expands across Asia Pacific, North America, and Europe. Companies are prioritizing water reuse, sustainability, and regulatory compliance while investing in sophisticated ZLD systems capable of delivering high water-recovery rates. Complex wastewater characteristics, testing requirements, and treatment processes further increase the value of advanced systems for pharmaceutical facilities.
Filtration to Record the Second-Fastest Process Growth
Filtration is forecast to be the second-fastest-growing ZLD process segment by value. Ultrafiltration, nanofiltration, and reverse osmosis remove suspended solids, dissolved salts, and other contaminants before wastewater enters thermal evaporation processes. Effective filtration reduces scaling, fouling, and energy consumption in evaporators and crystallizers, improving plant reliability and lowering downstream treatment costs.
Investment in advanced membrane systems is rising as regulatory requirements increasingly emphasize complete water reclamation and zero facility discharge. Developments in membrane durability, automation, and anti-fouling capabilities are strengthening long-term economic performance. Adoption across power generation, chemicals, pharmaceuticals, and electronics is expected to drive continued expansion of the filtration segment.
Middle East & Africa Emerges as the Second-Fastest-Growing Regional Market
The Middle East & Africa is projected to be the second-fastest-growing ZLD systems market by value, supported by industrial expansion and severe freshwater scarcity. Investments in oil and gas, petrochemicals, mining, and power generation are creating strong demand for industrial water recycling and waste-management systems.
Governments across the region are introducing stricter environmental requirements and supporting water-recycling initiatives intended to reduce dependence on desalination and groundwater extraction. Gulf countries are contributing significantly through infrastructure development and industrial growth programs. Large-scale ZLD installations can also deliver substantial financial returns in water-constrained industrial environments, reinforcing the region's position as a major development market.
