Microfiltration-adsorption hybrid system in organics removal from water

摘要

A series of experiments was conducted with a Millipore flat plate microfiltration module modified to incorporate in-line powdered activated carbon (PAC) addition. In-line PAC was mixed continuously through a spiral mixing device for a predetermined time prior entering a membrane unit. The results showed that this system is excellent in removing fulvic acid (FA). This system provides so sufficient contact time for PAC to adsorb organics compared to the system with in-line adsorbent addition. More than 85
