Doosan Heavy Industries & Construction announced on February 6 that it had signed a contract with Korea South-East Power Corporation (KOEN) to supply them with its advanced wastewater treatment technology – the zero liquid discharge (ZLD) system.
Doosan’s zero liquid discharge (ZLD) system treats flue gas desulfurization (FGD) wastewater of thermal power plants by combining its advanced membrane solutions, such as reverse osmosis (RO), and thermal processes involving evaporators and crystallizers. The company’s advanced wastewater treatment technology helps remove not only industrial liquid waste, such as mercury, which could be removed using existing wastewater treatment solutions, but it also eliminates nitrate and selenium, which fall under contaminants to regulate in the recently tightened environmental regulations adopted worldwide.
Doosan developed its advanced ZLD technology in-house, capitalizing on its industry-leading seawater desalination technologies for which it has an extensive track record. The company 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.
Seokwon Yun, Water BG CEO of Doosan Heavy Industries & Construction, said, “Winning this new project proves that our wastewater treatment solutions are recognized for its reliability and excellence. Doosan is poised to further serve our clients worldwide with our advanced wastewater treatment solutions, as complying with the stricter environmental regulations has become more critical than ever in recent years.”
