EngineeringCenter of Seawater MultipurposeUtilization, directed by Congjie Gao, academician of the ChineseAcademyof Engineering, is based on the platform of Ocean University of China SeawaterResources Multipurpose Utilization Laboratory. It is mainly engaged in thedevelopment and industrialization research of seawater desalination and watertreatment, utilization of seawater chemistry resources and marine finechemicals. It has successively launched a series of cooperation with ShengliOil Field, China Sinoma Group, Shandong Zhaojin Motian LLC, Datang HuangdaoPower Plant and Qingdao Ocean Chemical Engineering Factory in fields includingoil reinjection water treatment, seawater desalination, sewage treatment, etc.It has gained the support of the National “11thFive-Year” and “12thFive-Year” Key Technologies R&D Program, National High-tech R&D Program(863 Program), National Marine Public Welfare Projects and Shandong Science andTechnology Key Projects Fund. At present, research funding of ongoing projectsis nearly 8,000,000 yuan.
