Improvement of anti-biofouling properties of hollow fiber membranes with bismuth-BAL chelates (BisBAL).

In this study, hollow fiber membranes with and without bismuth dimercaptopropanol (Bis-BAL) additive were fabricated. Membranes were characterized in terms of permeability, surface properties, anti-biofouling and antibacterial properties. Membranes were operated in a lab-scale submerged membrane bioreactor (MBR). During the MBR operation, flux, chemical… CONTINUE READING
