The global zero liquid discharge systems market size reached USD 8.2 Billion in 2024. Looking forward, IMARC Group expects the market to reach USD 14.9 Billion by 2033, exhibiting a growth rate (CAGR) of 6.8% during 2025-2033. The market is witnessing substantial growth, driven by strict environmental policies and the escalating demand for sustainable water treatment techniques. Moreover, sectors including oil and gas, power generation, and chemicals are rapidly deploying ZLD systems to lower their wastewater production and improve resource efficiency, thereby propelling the market growth.
Zero liquid discharge (ZLD) systems refer to the strategic wastewater treatment solutions used for processing industrial plant discharges to prevent the release of liquid effluents in the water bodies. They include equipment and tools for ultrafiltration, reverse osmosis, crystallization and fractional electrodeionization (EDI). ZLD systems utilize crystallizers and membrane-based and multiple effect evaporation systems for the recovery and recycling of water. These systems also facilitate recycling and reuse of wastewater, thereby preventing the intake of freshwater. As a result, they are commonly used in process plants, bulk drug manufacturing units, textile factories and chemical plants, along with desalination and power plants.
The increasing demand for effective wastewater treatment solutions across industries is one of the key factors driving the growth of the market. Various industrial and manufacturing units utilize ZLD systems for the processing and disposal of brine concentrates. They are also used in coal-fired and thermal power plants located near water bodies for removing liquid and solid waste from the system and producing clean water that is suitable for reuse. The clean water obtained is further utilized as a coolant and for various industrial processes, such as cooling tower and boiler blowdown. In line with this, both private and public organizations are launching numerous water decontamination programs, which is also contributing to the growth of the market. Additionally, various product innovations, such as the development of hydrophobic hollow fiber membranes, are acting as other growth-inducing factors. These membranes are utilized for effective brine treatment and recovering useful resources from the water. Other factors, including the implementation of favorable government policies prohibiting the discharge of concentrated effluents in water streams, along with the increasing requirement for clean and potable water, are anticipated to drive the market toward growth.
