Global zero liquid discharge systems market is expected to reach USD 9.74 Billion by 2025, at a CAGR of 8.64% from 2018 to 2025. Imposition of strict environmental regulations along with growing concerns over the disposal of saline concentrates into water bodies are projected to drive the global zero liquid discharge systems market.  

Market Overview:

Zero-liquid discharge (ZLD) is a water treatment process in which all the wastewater is purified and recycled while leaving zero discharge at the end of the treatment cycle. It is an advanced wastewater treatment method that includes ultrafiltration, reverse osmosis, evaporation/crystallization, and fractional electrode ionization. ZLD systems significantly lower the waste volumes and decrease the cost associated with waste management. Also, the ZLD systems have the ability to treat and recover valuable byproducts such as ammonium sulfate fertilizer from the wastewater. A well-designed, efficient, and effective zero liquid discharge wastewater treatment system is able to handle any fluctuations in flow rate and capable to recover around 95% to 99% of water for reuse. Implementation of strict environmental regulations pertaining to effluent treatments such as U.S. Environmental Protection Agency’s Steam Electric Power Generating Effluent Guidelines is anticipated to boost the global demand for the ZLD systems.
