Development of a novel high performance filtration system - Optimization of operating conditions

► A new filtration system with a spiral guide rod in a ceramic tube and slurry prepared in a well dispersed state has been developed. ► The filtration flux of this system was dramatically improved compared to the conventional cross-flow filtration system. ► The filtration flux increased with the flow rate of circulation and did not depend on the filtration pressure. ► The achieved optimal value of the pitch produced the maximum filtration flux. ► Fouled particles can be removed easily and the filtration flux can be recovered to the initial condition by ultrasonication.
