Membrane filtration technology has attracted extensive attention in academia and industry due to its advantages of eco-friendliness related environmental protection high efficiency. Polyamide thin-film composite nanofiltration (PA TFC NF) membranes have been widely used their separation performance. Non-acid-resistant PA NF face tremendous challenges an acidic environment. Novel relatively acid...

In this work we presented a general strategy for the fabrication of membranes with well-defined ions transport channels through solvent-responsive layer-by-layer assembly (SR-LBL). Multilayered poly (diallyldimethylammonium chloride) (PDDA) and poly (acrylic acid) (PAA) complexes were first introduced on the inner pore wall and the surface of sulfonated poly (ether ether ketone)/poly (ether sul...

The manufacture of Prolastin®-C (alpha1-proteinase inhibitor [human]) uses a modified process for Prolastin® that incorporates two new dedicated virus reduction steps: a unique solvent/detergent treatment and a small pore nanofiltration. The Prolastin-C manufacturing process was investigated for its capacity to remove or inactivate relevant viruses or models of relevant viruses by evaluating in...

A lactose-hydrolyzed milk with low sweetness was developed using nanofiltration. Raw milk was treated with 0.03% β-galactosidase at 4°C for 24 h to hydrolyze lactose partially. The resultant lactose-hydrolyzed milk containing 0.43% lactose was then concentrated using a nanofiltration membrane to reach concentration factor of 2.13. The concentration factors and coefficients of retention of milk ...

Aqueous phase separation (APS) is a recently developed sustainable alternative to the conventional organic solvent based nonsolvent-induced (NIPS) method prepare polymeric membranes. In APS, polyelectrolytes are precipitated from aqueous solutions through pH or salinity switches. Although APS differs NIPS in polymer and solvents, they share many tuning parameters. this work, we investigate APS-...
