WebAlthough membranes with surfaces resistant to bacterial adhesion are expected to have higher resistance to biofouling as well, our recent study reported that membrane surface properties have no significant relationship with biofouling under no filtration condition (Lee et al., 2010 [27]). WebThe AgNP@SiO 2 -immobilized membrane showed excellent antibacterial properties against Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus, even with a relatively low particle coverage. Importantly, the separation performance (water flux and salt rejection) of the membrane was not impaired by particle immobilization. WebBoth filters performed with efficient solvent clearance and track a theoretical process in which no retention of the solvent by the membrane is assumed, calculated using a sieving coefficient (S) of 1. The decrease in DMSO removal rate after ~8 diavolumes may be due to the presence of dead legs in the system and charge interactions. Figure 2. shrimp crab or lobster
