ABSTRACT
Objective:
To study the influencing factors of membrane flux (J) and membrane fouling resistance (Rf) in the mincrofiltration of the water extract of Cassia Semen with ceramic membrane.Methods:
Based on single-factor experiment, the process parameters in the mincrofiltration of the water extract of Cassia Semen were optimized by orthogonal design method using weighted composite score of Rf and J as evaluation. The correlation between Rf and J with main four process parameters was analyzed.Results:
The best microfiltration process condition was as follow Membrane aperture size was 0.2 μm, concentration of the water extract of Cassia Semen was 50.0 g/L, transmembrane differential pressure was 0.1 MPa, and crossflow velocity was 3.32 m/s. Membrane aperture size had a significant correlation with Rf and J.Conclusion:
The process parameters have an important effect on Rf and J. The primary and secondary order of the effect of four process parameters on Rf and J is as follow Membrane aperture size > transmembrane pressure > feed concentration > crossflow velocity.
