The latest report by IMARC Group, titled “Zero Liquid Discharge (ZLD) Systems Market Report by Process (Pretreatment, Filtration, Evaporation and Crystallization), Systems (Conventional ZLD Systems, Hybrid ZLD Systems), Technology (Thermal-based, Membrane-based), End Use Industry (Power, Oil and Gas, Metallurgy and Mining, Chemicals and Petrochemicals, Pharmaceutical, and Others), and Region 2025-2033,” finds that the global zero liquid discharge (ZLD) systems market size reached USD 8.2 Billion in 2024. Zero liquid discharge (ZLD) systems refer to the strategic wastewater treatment solutions designed to remove all the liquid waste from industrial plants to prevent the release of effluents in the water bodies. These systems employ advanced wastewater/desalination treatment technologies for ultrafiltration, reverse osmosis, crystallization and fractional electrodeionization (EDI). They also facilitate recycling wastewater and purifying clean water that is suitable for reuse. Consequently, ZLD systems are widely used in process plants, bulk drug manufacturing units, textile factories and chemical plants, and desalination and power plants.
Global Zero Liquid Discharge (ZLD) Systems Market Trends:
The market is primarily driven by the increasing demand for effective wastewater treatment solutions across various industries. Besides this, ZLD systems are also utilized in coal-fired and thermal power plants located near water bodies to remove liquid and solid waste from the system and produce clean water that is suitable for reuse. In addition, both private and public organizations are launching numerous water decontamination programs, which represent another major growth-inducing factor. Moreover, the introduction of hydrophobic hollow fiber membranes that assist in effective brine treatment and recovering useful resources from the water is also augmenting the market growth. Furthermore, the implementation of favorable government policies prohibiting the discharge of concentrated effluents in water streams and the increasing requirement for clean and potable water are anticipated to create a positive market outlook in the coming years. Looking forward, IMARC Group expects the market value to reach USD 14.9 Billion by 2033, exhibiting a CAGR of 6.8% during the forecast period (2025-2033).
