Formation of Dynamic Membrane for Printing Wastewater Reuse
This paper presented a new type of powdered activated carbon (PAC) dynamic membrane on porous ceramic tubes to reuse of washing water from secondary treated printing wastewater. Various operation parameters which can affect the separate characteristics of the dynamic membrane (DM) were considered, such as trans-membrane pressures, formation time, cross flow velocity and suspended particles concentration. With the help of grey relational analysis (GRA), a fast and effective methodology for the optimization of the preparation process of the DM was obtained. Under this condition, the prepared membrane had a uniform and compact structure and the highest COD removal rate. The renewed membrane by backwashing can reach up to 90% of initial permeability each time. The result shows that PAC dynamic membrane was considered as a promising method for purification aimed at reuse of printing wastewater, resulting in direct environmental and economic benefits.
