in this study, nf membrane was used for surface water treatment. the rejection of organic material, measured as total organic carbon (toc), by nanofiltration was examined. the effects of application of pre-ozonation and pre-chlorination on toc removal are discussed and their performances are compared with the performances of nanofiltraion system without pretreatment process. in nf, natural orga...

In this study, air pollution control (APC) residue is conducted with water washing process to reduce its chloride content. A novel electrical conductivily (EC) measurement method is proposed to monitor the dynamic change of chloride concentrations in leachate as well as the chloride content of the residue. The method equally applies to various washing processes with different washing time, liqu...

This paper presents a novel system that protects digital contents in home environment by embedding both perceptible and imperceptible watermarks into contents. The imperceptible watermark is used for illegal copy detection, usage states management and forensic tracking.
