We designed and built a landmark seawater desalination plant for Wanhua Chemical Group, one of the world's top 20 chemical companies, at their Penglai Industrial Park in Yantai, Shandong. With a total designed capacity of 300,000 cubic meters per day, to be delivered in three phases, this project is the largest industrial membrane-based seawater desalination initiative planned in China to date. Upon commissioning, it will not only contribute to the protection of local freshwater resources but also support the ecological transformation of the industrial sector.
