Bubbleless membrane aeration is a promising method for water oxygenation. In this work, the oxygen transfer characteristics of hydrophilic treated polypropylene (PP) microporous hollow fiber membranes were studied. Both cross flow and parallel flow modules were used for the bubbleless aeration of wa
Polysulfone hollow fiber membranes were fabricated by a dry/wet spinning process, with N-methyl pyrrolidinone (NMP) and water as solvent and coagulant, respectively. The results indicate that air-gap length and ambient humidity have dramatic effect on the membrane morphology. Macrovoids in the membr
