This paper introduces the application of integrated membrane separation and concentration technology in heparin sodium extraction. Ceramic microfiltration clarifies enzymatic hydrolysate, ultrafiltration intercepts heparin, and nanofiltration with diafiltration achieves desalination and concentration. Compared with traditional processes, this low‑temperature method raises yield, cuts ethanol consumption and wastewater, and allows smooth scale‑up from lab trials to mass production, though membrane fouling needs to be managed via CIP and process tuning.
Membrane filtration offers efficient, low-temperature clarification and concentration for fruit wine. It removes suspended impurities, prevents sediment, retains natural fruit aroma and extends shelf life, an advanced alternative to traditional fruit wine filtration processes.
