Zero Liquid Discharge (ZLD) Systems Market Set to Touch USD 11.8 Billion by 2029

Zero Liquid Discharge (ZLD) Systems Market

BlueWeave Consulting, a leading strategic consulting and market research firm, in its recent study, estimated the global zero liquid discharge (ZLD) systems market size at USD 7.04 billion in 2022. During the forecast period between 2023 and 2029, BlueWeave expects the global zero liquid discharge (ZLD) systems market size to grow at a significant CAGR of 7.73% reaching a value of USD 11.77 billion by 2029. The stringent government regulations regarding wastewater discharge, which has resulted in the destabilization of the ecosystem and water bodies boosting the market growth. ZLD systems aim to remove all liquid and solid waste from a system and produce clean water suitable for reuse. The captured solid waste can be repurposed for various industrial processes. The clean water obtained from ZLD water treatment systems is used as a coolant for systems and in different industrial processes such as cooling tower blowdown, boiler blowdown, and oil refinery effluent. The growing demand for water conservation and environmental protection in various industries has also led to an increased preference for zero liquid discharge systems.

Opportunity: Increasing Government Regulations Regarding Wastewater Management and Discharge

Governments across countries are implementing strict regulations on wastewater discharge, including limits on the number of pollutants that can be discharged into water bodies. As a result, industries are increasingly turning to ZLD systems to comply with these regulations and avoid costly penalties. For example, in India, the Central Pollution Control Board (CPCB) has mandated that all industries in heavily polluted areas must implement ZLD systems by 2022.

Similarly, the US Environmental Protection Agency (EPA) has implemented the Effluent Limitation Guidelines (ELG) program, which sets limits on the amount of pollutants that can be discharged from industrial facilities into water bodies. Companies in the zero liquid discharge (ZLD) systems market are benefiting from these regulations by providing innovative solutions that enable industries to comply with these regulations. For example, Suez Water Technologies & Solutions has developed the Aquapure ZLD system, which is designed to recover up to 95% of the wastewater generated by industries and eliminate liquid discharge. Similarly, Aquatech International offers a range of ZLD solutions, including its HERO (High-Efficiency Reverse Osmosis) technology, which provides an efficient and cost-effective solution for treating wastewater. As governments continue to implement stricter regulations on wastewater discharge, the demand for ZLD systems is expected to continue to grow. The development of new and innovative technologies, coupled with the increasing focus on environmental sustainability, is likely to further drive the growth of the global ZLD systems market in the coming years.
