An integrated enzymatic membrane and concentrated to a method cephalexin concentrated

A method of integrated enzymatic membrane and concentrated concentrated cephalexin, cephalexin relates to a method of concentrating. The present invention is a method to solve the conventional need to use highly concentrated cephalexin extraction solvent will be harmful to the environment and energy problems. METHODS: a, prepared by the enzymatic cephalexin concentrated mother liquor feed is placed in the storage tank; two, through the fine filtration means; third, through an ultrafiltration membrane unit; Fourth, through a nanofiltration membrane means; V. transmitted to the reaction permeable membrane unit, i.e., too. The method of the present invention permits the original cephalexin solution was concentrated more than 10 times, low energy consumption, significantly reduce the use of the process of extraction solvent used interchangeably, reducing the impact on human health and environment-friendly. The present invention is for concentrating cephalexin.
