Effect of UF membrane separation on adsorption process of vitamin B_(12)

Yueping Zhang

Abstract

The feed quality of vitamin B_(12) adsorption process is improved with UF membrane separation technology beforehand.Fermentation filtrate of vitamin B_(12) is treated with UF membrane of MWCO 10 000.Adsorption experimentation of UF filtrate shows that high-unit's purity increases 50.3%and recovery ratio increases 12.5%,whereas consumptions of adsorption process decrease to different extent.
