- Hansung Cleantech Co., Ltd. is an environmental engineering and industrial water treatment company that specializes in the engineering, procurement, and construction (EPC), as well as operation and maintenance (O&M), of advanced industrial water processing systems for high-tech manufacturing sectors. Founded in 1990 and headquartered in Seoul, South Korea, the company delivers specialized water treatment infrastructure primarily to the semiconductor, display, electronics, petrochemical, secondary battery, and power generation industries. Hansung Cleantech Co., Ltd. operates across multiple core product and service categories, comprising: ultrapure water (UPW) production systems engineered to eliminate micro-particles, dissolved oxygen, and trace silica for semiconductor fabrication; pure water and demineralized industrial water preparation systems; industrial wastewater treatment (WWT) and chemical neutralization plants; advanced water recycling, reclamation, and zero-liquid discharge (ZLD) systems; seawater desalination facilities utilizing membrane and thermal processes; environmental infrastructure engineering including sludge drying, thickening, and thermal incineration facilities; industrial liquid waste treatment and waste battery recycling process solutions; and long-term facility operation, environmental monitoring, and comprehensive maintenance management services. The company conducts business primarily in South Korea, while maintaining international operations, project execution capabilities, and regional operating subsidiaries in Vietnam, Hungary, and the United States. In recent corporate developments, the company completed a major structural reorganization following an absorption merger with its listed parent company, EN Corporation, subsequently unifying its corporate identity and rebranding the KOSDAQ-listed entity under the Hansung Cleantech Co., Ltd. name. Operationally and strategically, the company has secured substantial multi-year EPC infrastructure contracts, including major ultrapure water system installations and wastewater treatment facility packages for Samsung Electronics at its P4 and P5 Pyeongtaek fabrication complexes, wastewater treatment system installations for SK Hynix at the Yongin Semiconductor Cluster and Cheongju P&T7 facilities, an ultrapure water EPC contract for DB HiTek at its Sangwoo fab, and international ultrapure water infrastructure deliveries for SoulBrain in the United States. Additionally, Hansung Cleantech has advanced the commercialization of state-backed research initiatives focused on the localization of high-purity ultrapure water production technologies for semiconductor manufacturing, strengthening its vertically integrated environmental platform spanning plant design, equipment supply, and lifecycle facility management.
