Global Zero Liquid Discharge System Market Size, Share, Growth Analysis, By System, By ProcessSub-SegmentsEvaporation/Crystallization, Filtration, and Pre-treatment, By End-Use - Industry Forecast 2024-2031

Global Zero Liquid Discharge (ZLD) Systems Market size was valued at USD 5.84 billion in 2022 and is poised to grow from USD 6.32 billion in 2023 to USD 11.87 billion by 2031, growing at a CAGR of 8.2% in the forecast period (2024- 2031).

Zero Liquid Discharge (ZLD) Systems are gaining popularity as they ensure that industrial wastewater is not discharged into the environment. This zero discharge is achieved by treating wastewater through recycling and subsequent recovery and reuse for industrial purposes. Governments worldwide have implemented stringent regulations for the treatment of wastewater generated by industries. As a result, many industries are now implementing ZLD systems primarily for end-of-pipe treatment to comply with these regulations. Cost-effective designs for ZLD systems can be identified, as they can be integrated into interplant water network systems either as central or distributed units. Industries globally invest significant amounts of money in waste management. Therefore, ZLD systems help reduce waste volumes using cost-effective techniques. They also facilitate on-site water recycling, leading to reduced treatment needs and lower water acquisition costs and associated risks. Furthermore, ZLD systems contribute to reducing the number of trucks and other vehicles involved in off-site wastewater disposal, thereby reducing their greenhouse gas emissions and the associated risks of community road incidents.

Drivers of the Global Zero Liquid Discharge (ZLD) Systems Market

The rapid industrialization and the abundance of seawater have led to a significant scarcity of fresh water for the growing population. Salination has become a major concern in the Middle Eastern region. In response to this issue, Dusan Energy announced in August 2022 that they would invest 840 billion to build a saltwater desalination facility in Saudi Arabia. One of the key applications of the zero liquid discharge system is its ability to provide drinkable water through the desalination of seawater. This addresses the need for fresh water required for drinking, industrial purposes, and domestic needs, thereby compensating for the scarcity of fresh water.

Restraints in the Global Zero Liquid Discharge (ZLD) Systems Market

The significant investment and capital expenditure required for zero liquid discharge systems have been a major hindrance to market growth. To address this issue, alternative solutions for wastewater treatment with lower operating costs have emerged. These alternative solutions enable manufacturers and municipal authorities to recover approximately 95% of liquid discharge compared to zero liquid discharge arrangements.

Market Trends of the Global Zero Liquid Discharge (ZLD) Systems Market

Power plant owners prioritize water management due to various factors, including stricter environmental regulations on wastewater discharge, regional water shortages, and public perception of power plants. Implementing Zero Liquid Discharge (ZLD) systems can help address these challenges.
