The Doosan zero liquid discharge (ZLD) system, which was developed in-house, treats flue gas desulfurization (FGD) wastewater of thermal power plants by combining its membrane solutions, such as reverse osmosis (RO), and thermal processes involving evaporators and crystallizers.

Doosan will be in charge of the entire project including the design, manufacturing and commissioning processes of the Yeongheung Thermal Power Plant, which is scheduled to be completed by August 2018.
 
Once completed, the plant will be capable of recycling 1250m3 of FGD wastewater daily.
