Membrane Separation Process of Oxytetracycline Fermentation Broth with Magnetization

The oxytetracycline filtered broth by plate and framefilter was purified and concentrated with membrane separation techniques in magnetic field.Experiment results indicate that ultrafiltration membrane PES20 and nanofiltration membrane NF270 separation properties is better effect in 0.4 T,and the production quality of oxytetracycline increased compared with no magnetization treatment process or the original technology.
